Description

  The present invention relates to a skinning method for producing a processed food with a skin by attaching a large number of strip-like outer skin materials to the front and back surfaces of an inner packaging material.

  Conventionally, various types of processed foods with skin, for example, processed foods such as shumai mainly made of minced meat, have been proposed, and are described in, for example, JP-A-10-327825, which is Patent Document 1 described below. As described above, there has been proposed a form in which strip-like or shredded strip-like outer skin materials are attached to the front and back surfaces of an inner packaging material as a material.

According to Patent Document 1, the skin material of processed food is, for example, a material obtained by kneading flour or the like with salt water and extending it into a thin sheet and cutting it into strips. It is said that it is used by making it adhere to the surface of a dumpling.
Japanese Patent Laid-Open No. 10-327825

  However, the processed food with a skin using the above-described skin material is required to have a skillful skill in a cooking operation in which the skin material is uniformly adhered to the surface of the dumpling-like material that is the inner packaging material. For this reason, even today, the work of attaching the elongated strip-shaped outer skin material to the front and back surfaces of the inner packaging material must be done manually by the cooking worker, and such work cannot be mechanized and skillful cooking. There was a problem that an excessive burden was imposed on the worker.

  The present invention was made in order to solve the above-mentioned problems, and a strip-like or strip-like outer skin material is mechanically attached to the front and back surfaces of the inner packaging material as a material, It aims at providing the method which can manufacture a processed food with a skin.

  In order to achieve this object, the processed food skinning method according to claim 1 is a method for manufacturing a skinned processed food in which a large number of strip-like outer skin materials are attached to an inner packaging material. A lot of outer skin material is laid and loaded with a predetermined width and thickness, and the belt material is transferred from the upstream side to the downstream side, and the width direction of the belt transferred by the outer skin material transfer step. An inner packaging material supplying step of attaching an outer skin material loaded on the belt to one side of the inner packaging material by placing the inner packaging material formed in a shape having a front surface and a back surface on one side; and The belt is bent upward in a substantially U shape by lifting both sides in the width direction of the belt being transported and raising the belt in the downstream direction of the belt transport direction from the placement position of the inner packaging material in the inner packaging material supply process. Belt deformation process to be deformed and its By the belt deformation process, the inner packaging material placed on the outer skin material on one side in the width direction of the belt is dropped to the central portion in the width direction of the belt, and the outer skin material is attached to the other surface of the inner packaging material. And an inner packaging material reversing step.

  According to the processed food skinning method of claim 1, a large number of outer skin materials are laid on a wide belt with a predetermined width and thickness, and the belt is transferred from the upstream side to the downstream side by the outer skin material transfer step. to continue. Then, on the way to the downstream side of the belt, the skinned processed food packaging material formed into a form having a front surface and a back surface is formed on a number of skin materials loaded on the belt by the packaging material supply process. Placed on. At this time, in the inner packaging material supplying step, the inner packaging material is placed so that one side of the inner packaging material faces the outer skin material on one side in the width direction of the belt. The

  The inner packaging material placed on the outer skin material in the inner packaging material supply process is transported downstream by the outer skin material transporting process together with the belt while being placed on one side in the width direction of the belt. When the belt reaches a predetermined position downstream of the placement position of the inner packaging material, the belt is deformed by the belt deformation process. According to this belt deformation process, both sides in the width direction of the belt are lifted upright while being transferred by the outer skin material transfer process.

  Then, the inner packaging material is dropped from one side in the width direction of the belt toward the bottom of the belt curved in a substantially U shape, that is, toward the center in the width direction of the belt. At this time, the inner packaging material is dropped so that the other surface thereof, that is, the non-attached surface of the outer skin material faces the central portion in the width direction of the belt. Then, the other side of the inner packaging material is placed so as to face the outer skin material located on the center in the width direction of the belt, and the outer skin material is attached to the other side of the inner packaging material.

  In other words, the belt deformation process causes the inner packaging material reversal process to reverse the front and back of the inner packaging material on the belt, and this inner packaging material reversal process also attaches the outer skin material to the other side of the inner packaging material. Thus, a large number of strip-like outer skin materials are attached to both the front and back surfaces of the inner packaging material.

  By the way, when the belt loading surface is simply flat, the outer skin material on both sides in the width direction of the belt slides down to the center in the width direction of the belt in the process of deforming the belt by the belt deformation process. Then, along with the sliding-down of the outer skin material, the inner packaging material placed thereon may also slide down without being turned upside down at the center in the width direction of the belt. It was difficult to reliably attach a large number of strip-like outer skin materials to the other side of the material. Therefore, in the processed food skinning method of claim 2, the following means was adopted.

  The processed food skinning method according to claim 2 is the processed food skinning method according to claim 1, wherein the belt protrudes in a convex shape from the surface of the belt and is continuously formed in the transport direction of the belt. The inner packaging material reversing step is a process in which both sides in the width direction of the belt stand upright due to deformation of the belt by the belt deformation step, and the both sides in the width direction of the belt by the plurality of protrusions. This prevents the skin material from peeling off from the top.

  According to the processed food skinning method of the second aspect, in addition to acting in the same manner as the processed food skinning method of the first aspect, both sides of the belt in the width direction are formed by a plurality of protrusions during the belt deformation process. The skin material loaded on the part is prevented from peeling off. For this reason, during the deformation process of the belt, it is avoided that the outer skin material on both sides in the width direction of the belt slides down to the central portion in the width direction of the belt, and slipping of the inner packaging material induced by the sliding-down of the outer skin material. Falling is also prevented. As a result, the inner packaging material reversing step can be properly induced by the belt deformation step, and the inner packaging material can be reliably inverted and dropped from one side in the width direction of the belt to the central portion.

  The processed food skinning method according to claim 3 is the processed food skinning method according to claim 1 or 2, wherein the processed food skinning method is arranged opposite to each other on both sides of the belt in the width direction with an interval narrower than the belt width. The belt deforming step, when the belt deforming step lifts both sides in the width direction of the belt to stand upright, the belt deforming member passes the belt between the belt deforming members, As the belt moves toward the downstream side in the transport direction, both sides in the width direction of the belt are lifted so that the inclination angles of the both sides in the width direction of the belt gradually increase.

  According to the processed food skinning method of claim 3, the belt is being transferred between the belt deforming members in the same manner as the processed food skinning method of claim 1 or 2, and the belt being transported downstream in the transport direction is passed. Thus, the both sides in the width direction of the belt are lifted so that the inclination angle of the both sides in the width direction of the belt, that is, the angle formed by the raised side in the width direction and the horizontal plane gradually increases.

  As a result, both sides in the width direction of the belt are deformed so as to gradually rise as the belt moves downstream. For this reason, both sides of the belt in the width direction are suddenly deformed, and the enveloping material is not only reversed by that momentum, but can be prevented from rolling over more than one rotation, resulting in an incentive by the belt deformation process. By the inner packaging material reversing step, the inner packaging material can be reversed more reliably.

  The processed food skinning method according to claim 4 is the processed food skinning method according to any one of claims 1 to 3, wherein the inner packaging material is dropped to the center in the width direction of the belt by the inner packaging material reversing step. The outer skin material adhering to both sides in the width direction of the belt in the deformation process by the belt deformation process is peeled off by scraping from the belt, and moved to the center in the width direction of the belt. It is provided with a skin material peeling step for dropping.

  According to the processed food skinning method of claim 4, the same effect as in any of the processed food skinning methods of claims 1 to 3 is achieved, and the inner packaging material is bent into a substantially U shape of the belt by the inner packaging material reversing step. After being dropped to the bottom portion, that is, the central portion in the width direction of the belt, the outer skin material adhering to both sides in the width direction of the belt is scraped off and peeled off from the belt by the outer skin material peeling step. Then, the peeled many outer skin materials are put on the inner packaging material placed at the center in the width direction of the belt, and as a result, the outer skin material can be uniformly and evenly adhered to the inner packaging material.

  The processed food skinning method according to claim 5 is the processed food skinning method according to any one of claims 1 to 4, wherein the processed food skinning method is disposed on each of both sides in the width direction of the belt and on both sides in the width direction of the belt. Spatula members that are in contact with each other are provided, and the outer skin material peeling step scrapes and peels off the outer skin material adhering to both sides in the width direction of the belt being transferred by the spatula member.

  According to the processed food skinning method of claim 5, the spatula member operates in the same manner as the processed food skinning method of any of claims 1 to 4, and the spatula member of the belt transported downstream in the transport direction. By abutting on both sides in the width direction, the outer skin material is scraped off and peeled off from both sides in the width direction of the belt. That is, since the outer skin material is scraped off from the belt using the belt transfer motion, a unique power source for driving the spatula member is unnecessary, and accordingly, the use device and the use device for carrying out the present invention are not required. It can be simplified.

  The processed food skinning method according to claim 6 is the processed food skinning method according to claim 4 or 5, wherein the outer skin material is peeled off from the belt by the outer skin material peeling step on the downstream side in the belt transfer direction. In addition, the inner shell covered with the outer skin material by the pressing member that is disposed apart from the central portion in the width direction of the belt deformed by the belt deformation step and is rotatably supported in the belt transfer direction. A food pressing step for pressing the material from above is provided.

  According to this processed food skinning method of claim 6, the same effect as the processed food skinning method of claim 4 or 5 is applied, and the inner packaging material covered with the outer skin material in the outer skin material peeling step is loaded on the belt. By passing below the pressing member in such a state, the inner packaging material is pressed by the pressing member, the outer skin material is pressed against the inner packaging material, and the outer skin material is hardly peeled off from the inner packaging material.

  According to the processed food skinning method of the present invention, the strip-shaped or shredded strip-shaped outer skin material can be mechanically attached to the front and back surfaces of the inner packaging material, which is used as an ingredient. Even if an excessive burden is not imposed, there is an effect that the outer skin material can be continuously and uniformly attached to the front and back surfaces of the inner packaging material.

The separation conveyor 8 is disposed on the downstream side of the skinning processing conveyor 2, and a gap having a predetermined width is formed between the upstream end of the separation conveyor 8 and the downstream end of the skinning conveyor 2. Is provided. The gap between the separation conveyor 8 and the skinning conveyor 2 functions as a first recovery slit 23 for dropping the skin material K on the skinning belt 11 onto the recovery conveyor 9.

  The groove width of the first recovery slit 23 is made smaller than the planar size of the material G, and the height of the conveying belt 8a of the separation conveyor 8 is larger than that of the skinning belt 11 of the skinning conveyor 2. It is set low. For this reason, it is possible to prevent the ingredient G from falling from the first recovery slit 23 when the processed food S with skin is transferred from the skinning processing conveyor 2 to the separation conveyor 8. On the other hand, the skin material K remaining on the skinning belt 11 is dropped downward from the interval between the skinning conveyor 2 and the separation conveyor 8 and loaded on the transport belt 9a of the recovery conveyor 9.

  As shown in FIG. 2, a belt conveyor 10 of the next process is disposed on the downstream side of the separation conveyor 8, and an upstream end of the belt conveyor 10 of the next process and a downstream end of the separation conveyor 8 are There is a slight gap between them. The gap between the separation conveyor 8 and the belt conveyor 10 in the next process functions as a second collection slit 24 for dropping the skin material K scattered on the separation conveyor 8 onto the collection conveyor 9.

  The groove width of the second recovery slit 24 is also smaller than the planar size of the material G, and is further smaller than the groove width of the first recovery slit 23. Further, the height of the stacking surface of the conveyor belt 10 a of the belt conveyor 10 in the next process is set lower than that of the conveyor belt 8 a of the separation conveyor 8. For this reason, the transfer of the processed food S with skin is smoothly performed from the separation conveyor 8 to the belt conveyor 10 of the next process.

  As shown in FIGS. 1 and 2, the recovery conveyor 9 is disposed below the skinning conveyor 2, the separation conveyor 8, and the belt conveyor 10 of the next process, and the first and second recovery slits described above. 23 is a belt conveyor for stacking the skin material K dropped from 23 and 24 on the transport belt 9a and sending it back to the skin supply device 3. As a result, a large amount of the skin material K left over in the skinning process by the skinning conveyor 2 can be collected and supplied again onto the skinning belt 11 of the skinning conveyor 2.

  3 is a cross-sectional view of the skinned belt 11 in a flat state and a side view of the transfer conveyor 12 of the tool supply device 4, and is a partial vertical cross-sectional view taken along the line II-II in FIG. is there. In FIG. 3, in the leather belt 11, the transfer direction refers to a direction perpendicular to the paper surface, and the width direction refers to the left-right direction in the figure.

In addition, a plurality of ridges 25, 25,... Project from the stacking surface of the leather belt 11, and the plurality of ridges 25, 25,. It is formed continuously in the transfer direction (see FIGS. 1 and 4). In this embodiment, a total of four protrusions 25 are provided at equal intervals in the width direction of the leather belt 11 (left and right direction in FIG. 3). Since the spatula member 21 of the peeling device 7 is in contact, the protrusion 25 is not provided.

  The plurality of protrusions 25, 25,... Are peeled from the vertical portions 11 a, 11 a of the skinned belt 11 in the process in which both sides in the width direction of the skinned belt 11 are vertically held by the belt deformation device 5. The material K is prevented from peeling off and falling. That is, the skin material K on the leather belt 11 is restrained without being slipped off from the vertical portions 11a and 11a of the leather belt 11 by being caught by the plurality of protrusions 25, 25,. It is.

  The tool supply device 4 is arranged in a state where the downstream end (upper left side in FIG. 3) of the transfer conveyor 12 is spaced above the skinning belt 11. For this reason, when the ingredient G placed on the loading surface of the ingredient supply belt 13 of the transfer conveyor 12 reaches the downstream end of the conveyer 12, the non-contact surface with the ingredient supply belt 13 faces downward. Then, it is peeled off from the tool supply belt 13 and dropped onto the skinning conveyor 2. Then, the skin G is placed on the skin K in a state in which one side of the ingredient G is directed to the layer of the skin K on the skinning conveyor 2, and a large number of skins K are attached to one side of the ingredient G. .

  In the peeling device 7, the upper end portions of the support poles 19 are bent at substantially right angles, and the ends of the bent portions become the arm portions 19 a extending toward the substantially center in the width direction of the skinning conveyor 2. ing. The spatula member 21 is detachably attached to the tip part of the arm part 19 a of the support pole 19 via the connecting fitting 20. On the other hand, the lower end portion of each support pole 19 is inserted into a fixing bracket 22 attached to the gantry frame 16 of the skinning conveyor 2, and this insertion portion is fastened to the fixing bracket 22 with a bolt.

  For this reason, the direction and height of the arm portion 19a of the support pole 19 can be changed and adjusted by loosening the bolt and rotating the lower end portion of the support pole 19 within the fixing bracket 22. In addition, a plurality of attachment positions of the fixing bracket 22 of the support pole 19 are provided in the frame frame 16 of the skinning conveyor 2 in the transfer direction of the skinning belt 11, and the attachment positions of the support poles 19 and 19 are determined. It can also be changed.

  Each connection fitting 20 has an arm portion 19a of a support pole 19 inserted in a through-hole drilled in the center thereof, and is fastened to the arm portion 19a of the support pole 19 by a bolt screwed from the outer periphery thereof. ing. For this reason, by loosening the bolts of the connection fitting 20, the connection fitting 20 can be rotated around the axis of the arm portion 19a, and the rotation angle of the spatula member 21 with respect to the arm portion 19a (direction) ) Can be changed.

  FIG. 4 is a plan view of the belt deforming device 5, the pressing wheel 6, and the peeling device 7 in the skinning processing conveyor 2 in a plan view. As shown in FIG. 4, the belt deformation device 5 has both the front rollers 14 and 14 and the rear rollers 15 and 15 disposed on both sides in the width direction of the leather belt 11, respectively. The distance between the rollers 14 and 14 and the distance between the subsequent rollers 15 and 15 is made narrower than the width of the leather belt 11.

  By passing the leather belt 11 between the upstream rollers 14 and 14 and the downstream rollers 15 and 15 thus configured while being transferred from the upstream side to the downstream side in the transfer direction, As the distance between the front rollers 14 and 14 approaches, both side portions of the width are gradually lifted from the substantially flat state.

  FIG. 5 is an enlarged cross-sectional view of the pair of front rollers 14 and 14 in the skinning processing conveyor 2 in a vertical cross-sectional view, and is a partial vertical cross-sectional view taken along the line VV in FIG. As shown in FIG. 5, the pair of front rollers 14, 14 in the belt deforming device 5 are arranged to face each other in the width direction of the skinning conveyor 2. By passing between the pair of front rollers 14, 14, the leather belt 11 is lifted substantially upright on both sides in the width direction and deformed into vertical portions 11 a, 11 a, and the center in the width direction is It is deformed into a curved bottom portion 11b that is curved in a substantially arc shape so as to be recessed downward.

  As shown in FIGS. 4 and 5, the belt deformation device 5 is configured such that the inclination angle of each vertical portion 11 a of the skin belt 11 gradually increases as the skin belt 11 approaches between the front rollers 14 and 14. In this manner, the vertical portion 11a of the leather belt 11 is gradually lifted. For this reason, it is prevented that the inclination angle of the vertical part 11a of the leather belt 11 suddenly changes from the flat state to the substantially upright state, and the vertical part 11a of the leather belt 11 is vigorously moved by the rapid change. It is possible to prevent the ingredient G from rolling over more than one rotation after passing upside down.

  FIG. 6 is an enlarged cross-sectional view of a pair of subsequent rollers 15 and 15 in the skin processing conveyor 2 in a vertical cross-sectional view, and is a partial vertical cross-sectional view taken along line VI-VI in FIG. As shown in FIG. 6, the pair of rear rollers 15, 15 in the belt deforming device 5 are arranged to face each other in the width direction of the skin processing conveyor 2, as in the case of the front rollers 14, 14. Then, the skinned belt 11 passes between the pair of rear rollers 15 and 15 so that the width of the curved bottom portion 11b is further narrowed.

  In this manner, the belt deformation device 5 has the front rollers 14 and 14 and the rear rollers 15 and 15 that gradually reduce the width of the curved bottom portion 11b of the leather belt 11, so that the load associated with the curved deformation is applied to the belt. It is possible to prevent the belt 11 from acting in a concentrated manner. For this reason, the load and resistance when the skin belt 11 passes between the rear rollers 15 and 15 having a narrow interval can be reduced, and the power load for transferring the skin belt 11 and the overload on the skin belt 11 itself can be reduced. Can be suppressed.

  Further, as shown in FIGS. 5 and 6, the pressing wheel 6 is disposed such that the outer peripheral surface thereof is spaced above the curved bottom portion 11 b of the leather belt 11. The width of the pressing wheel 6 is slightly smaller than the distance between the opposing surfaces of the vertical portions 11a and 11a of the leather belt 11 between the rear rollers 15 and 15. It can be rotated without frictional contact with the parts 11a, 11a.

  Further, the outer peripheral surface of the pressing wheel 6 is curved and formed in a substantially arc shape that is recessed upward when facing the curved bottom portion 11 b of the leather belt 11. For this reason, the processed food S with skin having the skin material K attached around the ingredients G is pressed so as to be sandwiched between the curved outer peripheral surface of the pressing wheel 6 and the curved bottom portion 11 b of the leather belt 11. Then, the skin material K is pressed around the ingredients G.

  7 is an enlarged cross-sectional view of the skinning conveyor 2 showing the installation state of the peeling device 7, and is a vertical cross-sectional view taken along the line VII-VII in FIG.

  As shown in FIG. 7, the spatula member 21 is formed of a thick and long rectangular plate-like elastic material having flexibility and flexibility, such as silicon resin. The spatula member 21 has a base end portion connected to the outer peripheral portion of the connection fitting 20, and a tip end portion that is in contact with the stacking surfaces on both sides in the width direction of the leather belt 11. Specifically, the tip of the spatula member 21 is not attached to both sides of the flat skinned belt 11 in the width direction, but is peeled by the belt deforming device 5 so as to be curved and deformed in a substantially U shape in cross section. The belt 11 is in contact with the vertical portions 11a and 11a.

  Here, the leather belt 11 continues to be transported while being bent and deformed by the belt deformation device 5, so that it always bends or loosens slightly. For this reason, since the vertical portions 11a and 11a of the leather belt 11 are also slightly deformed, when the skin material K attached to the vertical portions 11a and 11a of the leather belt 11 is peeled off by the spatula member 21, the spatula is removed. If the member 21 is hard, the skin material K cannot be removed sufficiently, and the skin material K may remain in the vertical portions 11 a and 11 a of the skin belt 11. In addition, since the skinned belt 11 of the skin material K is kept in contact with the spatula member 21 while being transported, there is a concern about damage due to frictional contact between them.

  Therefore, the spatula member 21 of the peeling device 7 is formed of an elastic material having flexibility and flexibility, and is flexible to deformation such as bending of the vertical portions 11a and 11a of the leather belt 11 by elastically deforming itself. Corresponding to the vertical standing portions 11a and 11a of the leather belt 11. Moreover, the peeling device 7 can also be used by changing the attachment position of the support poles 19 and 19 with respect to the gantry frame 16 of the skinning conveyor 2 and the extending direction of the arm portion 19a of the support poles 19 and 19. The relative positional relationship between the member 21 and the leather belt 11 can be adjusted.

  Next, with reference to FIG. 8, the processed food skinning method using the skinning apparatus 1 comprised as mentioned above is demonstrated. FIG. 8 is an explanatory diagram of the processed food skinning method, and shows an example of the state change of the ingredient G and the skin material K loaded on the skinning belt 11.

  First, the skinning belt 11 starts to be circulated and transferred at a constant speed by the skinning conveyor 2. Then, as shown in FIG. 8A, a large number of skin materials K are predetermined on the stacking surface when the skin-attaching belt 11 is transferred from the upstream side to the downstream side in the transfer direction by the skin supply device 3. Laid in width and thickness. As a result, a large number of skin materials K continue to be spread on the loading surface of the peeled belt 11 being transferred.

  On the other hand, the ingredient supply device 4 forms the ingredient G into a predetermined form, for example, a lump with a predetermined thickness on the front and back, and the molded ingredient G is formed on the ingredient supply belt 13 of the transfer conveyor 12 at predetermined intervals. Is mounted and supplied. At this time, the ingredient G is stacked such that one surface of the ingredient G comes into contact with the loading surface of the ingredient supply belt 13. At this time, the tool supply belt 13 of the transfer conveyor 12 continues to be transferred at a constant speed.

  When the skinning belt 11 passes below the transfer conveyor 12 of the tool supply device 4, as shown in FIG. 3, the material from the stacking surface of the tool supply belt 13 that reaches the downstream end of the transfer conveyor 12. G falls. Then, as shown in FIG. 8 (b), the dropped material G is loaded on one side in the width direction of the skinned belt 11 with one side facing the stacking surface of the skinned belt 11. It is placed on a large number of skin materials K. As a result, a part of the skin material K loaded on the leather belt 11 adheres to one side of the ingredient G.

  The transfer conveyor 12 conveys the material G at a constant speed and at regular intervals, and the skin belt 11 also conveys the skin material K at a constant speed, so that the material is disposed on the skin belt 11 at regular intervals. G is sequentially supplied.

  The ingredient G placed so that the skin material K is attached to one side in this way is in a state of being placed on one side in the width direction of the skinning belt 11 as shown in FIG. It is transferred to the downstream side together with the skinning belt 11. Then, on the downstream side in the transfer direction of the leather belt 11 with respect to the mounting position of the material G, the belt deformation device 5 performs the bending deformation of the transferred leather belt 11.

  Then, as shown in FIG. 8 (c), the both sides in the width direction of the leather belt 11 are gradually lifted from the substantially flat state and finally vertically up to the substantially upright state, and the upper part is opened. It is bent and deformed into a substantially U-shaped cross-sectional view. As described above, when the inclination angle of the vertical portions 11a and 11a of the leather belt 11 gradually increases due to the bending deformation, it is placed on one side in the width direction of the leather belt 11, that is, one vertical portion 11a. When the inclination angle of the vertical part 11a exceeds a predetermined threshold value, the ingredient G falls from the vertical part 11a on one side thereof toward the curved bottom part 11b of the leather belt 11 as shown in FIG. 8 (d). Resulting in.

  When the material G falls as shown in FIG. 8D, the curved bottom portion of the ingredient G is arranged such that the other side of the skin material K which is not attached is opposed to the curved bottom portion 11b of the skinned belt 11. Since it is placed on the skin material K in 11b, the skin material K also adheres to the other surface of the material G.

  Further, in the process in which both sides in the width direction of the belt are vertically erected, as shown in FIG. 8C, the skin material K may be peeled and dropped from the vertically erected portion 11 a of the leather belt 11. 25, 25,... For this reason, when the vertical portions 11a and 11a of the leather belt 11 are gradually lifted, the skin material K is prevented from slipping down from the vertical portions 11a and 11a to the curved bottom portion 11b. The sliding down of the ingredient G induced by sliding down is prevented. In this way, the ingredient G is reliably reversed and dropped to the curved bottom part 11b without sliding down from the vertical part 11a of the leather belt 11.

  Further, when the material G is peeled off from the vertical portion 11a of the skin belt 11, the vertical portion of both the skin belts 11 is separated by the spatula member 21 of the peeling device 7 on the downstream side of the peeling position. The skin material K adhering to the surfaces of 11a and 11a is scraped off. Then, the scraped skin material K is peeled off toward the curved bottom portion 11b of the skin belt 11, and the skin belt 11 as shown in FIG. 8 (e) or FIG. 8 (e '). The material G placed on the curved bottom portion 11b is covered. After that, the material G covered with the skin material K is pressed from above by the pressing wheel 6, and the skin material K is evenly and evenly attached to the material G, as shown in FIG. 8 (f). Then, the skinning process on the skinned processed food S is completed.

  After the skinned processed food S and the unused skin material K have passed under the pressing wheel 6 together with the skinning belt 11, as shown in FIG. It is conveyed to the end. Thereafter, the processed food S with skin is transferred to the belt conveyor 10 of the next process through the separation conveyor 8, while the remaining skin material K is recovered from the first and second recovery slits 23, 24. 9 is dropped onto the conveyor belt 9a, returned to the leather supply device 3 by the recovery conveyor 9, and loaded onto the leather belt 11 of the leather processing conveyor 2 again.

  The present invention has been described based on the embodiments. However, the present invention is not limited to the above-described embodiments, and various improvements and modifications can be easily made without departing from the spirit of the present invention. It can be guessed.

  For example, in the present embodiment, the transfer conveyor 12 of the tool supply device 4 has been described as mounting the material G only on one side in the width direction of the leather belt 11, but the mounting position of the material G is However, the present invention is not necessarily limited to this, and if the skin belt 11 is bent and deformed and the material G falls from the upright portions 11a and 11a, it does not collide with another material G. You may make it mount in order in the width direction one side part and other side part in the loading surface of the attaching belt 11 alternately.
