Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to an apparatus for crushing, stirring, and crushing surimi, etc., which is mainly used in the manufacturing process of fish paste products.

Conventional technology For example, fish paste products such as kamaboko, chikuwa, hanpen, and kaniashikaze kamaboko are made from fish meat obtained by harvesting raw fish using a meat-cutting machine, exposing it to water, and dehydrating it. After this fish meat is crushed, stirred, and crushed, each product is given a unique shape and flavor, and then heated in an appropriate method to make the product.

Currently, the grinding of fish meat in the above process is done by first pulverizing the frozen surimi using a cutter, then exposing it to water for dehydration, and leaving the unfrozen fish as it is. It is generally carried out using a crusher combined with a shaped pestle.

Problems to be Solved by the Invention In the conventional grinding machine, finely minced surimi or raw fish meat that has been exposed to water and dehydrated is placed in a rotating white, and the pestle rotates in the opposite direction to the white. It is designed to stir and crush the raw materials for Shiranai paste products.

However, such conventional grinding machines not only have problems in terms of work efficiency, but also the surface of the bowl-shaped surimi remains exposed to the atmosphere during the grinding process. Hygiene control throughout the workplace is difficult, and in order to prevent fish meat from becoming slurry (a phenomenon in which fish meat gels and loses fluidity), it is necessary to lower the temperature of the fish meat during mashing. It has many problems such as it is very difficult to keep it at the same level.

The present invention provides a crushing, stirring, and crushing device that can solve the conventional problems as described above.

Means for Solving the Problems The present invention provides a mortar body having a circumferential surface such as a cylindrical shape, a truncated cone shape, a dish shape, a barrel shape, etc., which is installed with its center line facing sideways or slightly inclined. A material input port and a material discharge port are provided at the upper and lower parts of the mortar, respectively, and the opening and closing are controlled by lids, and a scraping rotating shaft whose center line coincides with the center line of the mortar is provided on one side wall surface of the mortar. A scraper, which is rotatably provided, and which scrapes off at least material adhering to the inner surface of the circumferential surface of the mortar body and stirs and mixes the material within the mortar body as the scraping rotary shaft rotates. The scraping member is attached, and one or more rotary shafts for mashing, which are attached so that the mashing member can be replaced, are attached to one side wall surface of the mortar body on which the rotary shaft for scraping is provided. It is characterized in that the rotary shaft is rotatably mounted and supported below the centerline of the mortar body and parallel to or inclined at a predetermined angle to the centerline of the mortar body.

Function In the above, after putting the materials, auxiliary materials, additives, etc. as necessary into the mortar through the material input port, and sealing the material input port with a lid, the scraping rotating shaft is rotated at a speed of about 20 to 100 rpm, for example. When the rotary shaft for mashing is rotated at a high rotational speed and at the same time, the scraping member rotates as the rotary shaft for scraping rotates, scraping off the material attached to the inner circumferential surface of the mould. The material in the mortar is stirred and mixed, and the material being stirred and mixed as described above is strongly struck by the material being stirred and mixed as described above by the high-speed rotation of the rotary shaft for grinding, and the material is crushed into powder. Stir and mix materials in an extremely short time.
After the crushing and crushing are completed in a sealed space, the discharge lid is opened and the processed materials are discharged and collected from the discharge port by rotation of the two rotating shafts.

Embodiment An embodiment of the present invention will be described below with reference to the accompanying drawings.

In the figure, 1 is a mortar body, 2 is a rotary shaft for scraping that protrudes into the mortar body 1 from one side wall 3 of the mortar body 1, and the rotary shaft 2 for scraping is mounted on a bearing 4 on the outside of the side wall 3. , 5, and is rotatably driven by a motor 6 via sprockets 7, 8 and a chain 9 attached thereto.

The base of a scraping arm 10 that extends in the radial direction to near the inner surface of the circumferential surface 22 of the mortar body 1 is fixed to the tip of the scraping rotating shaft 2.
A scraping blade 11 along the inner surface of the circumferential surface 22 of the mortar body 1 is attached to the tip of the rotary shaft 2 for scraping.
As a result of the rotation, the scraping member 12 consisting of the scraping arm 10 and the scraping blade 11 rotates as a unit, scraping off the material adhering to the inner wall of the mortar body 1, and evenly stirring the material inside the mortar body 1. It's starting to mix.

In order to stir and mix the materials more effectively, a plurality of scraping members 12 may be provided radially at the tip of the scraping rotating shaft 2.

Reference numerals 13 and 13' denote rotary shafts for mashing, and the rotary shafts 13 and 13' for mashing are arranged at the lower part of the rotary shaft 2 for scraping, and similarly to the rotary shaft 2 for scraping, the rotary shafts 13 and 13'
The rotary shafts 13, 13' project into the mortar body 1 from one side wall 3 of the rotary shaft 13, 13', and are driven by motors 18, 18' to pulleys 19, 20, 19', 20' and a V-pulley hung thereon. It is designed to be rotationally driven via 21, 21', etc.

The rotary shafts 13 and 13' for grinding have a grinding rod 1.
The crushing members 14 such as 4' or cutters 14' are fitted through spacers 15 at appropriate intervals so as not to interfere with each other, and are fixed by screwing and tightening a nut 17 onto the threaded portion 16 at the end of the rotating shaft 13. ,
By removing the nut 17, the combination of types of crushing members 14 can be changed as appropriate depending on the type of material to be crushed.

The crushing rod 14' is for strongly pounding and crushing the material being stirred in the mortar 1 by the rotation of the scraping member 12 by the rotation of the rotating shaft 13, and the cutter 14'' is for rotating. By rotating the shaft 13' in one direction, the blade section cuts and crushes the material, and by rotating the shaft 13' in the opposite direction, the material is strongly struck with the thick back of the cutter to crush and crush the material.

The illustrated embodiment shows an example in which two rotary shafts for crushing are provided in parallel, but the number may be one, or if the capacity of the mortar 1 is large, three or more may be provided. Further, as in the illustrated embodiment, the rotary shaft for mashing may be disposed parallel to the rotary shaft for scraping 2, or the extension of the center lines of the rotary shaft for mashing and the rotary shaft for scraping may be mutually arranged. It is also possible to have a structure with a certain angle so that they intersect.

As described above, both the scraping rotating shaft 2 and the kneading rotating shafts 13 and 13' are structured to protrude into the mortar body 1 from one side wall 3 of the mortar body 1.
On the side 23 opposite the one side wall 3 there is no heavy object to be attached. Therefore, in the present invention, the mortar side part 23 facing one side wall 3 is sealed with a door 39 made of transparent or semi-transparent glass or synthetic resin, so that the outside of the door 39 is closed during the material crushing operation. The crushed state of the materials inside can be sufficiently checked visually from the inside, and since the door 39 is lightweight, opening and closing operations centering on the hinges 40 and 41 of the door 39 are extremely easy, and the crushing work is completed. Later cleaning, inspection, repair, etc. can be easily and fully performed by opening the door 39.

Although the door 39 is not shown, it goes without saying that it can be kept completely airtight by a locking mechanism.

Furthermore, since there is a risk that the inner surface of the door 39 will be rubbed by materials during the mashing process and its transparency may deteriorate over a long period of use, the inner surface of the door 39 may be made of transparent or semi-transparent material. It is desirable to attach a resin thin plate or thin film so that when the transparency decreases, the thin plate or thin film can be peeled off and replaced with a new one.

The upper surface of the mortar body 1 is provided with an input port 29 for inputting materials, auxiliary materials, additives, etc.
A discharge port 33 is provided at the bottom of the
is controlled to open and close by a lid 31 that rotates about a fulcrum 30, and the outlet 33 is controlled to open and close by a lid 35 that slides in the left and right direction in FIG. 2 while being guided by rails 36 and 37. It's summery. 34 is a grip handle for opening and closing the lid 35. The lids 31 and 35 are both adapted to keep the input port 29 and the discharge port 33 airtightly sealed.

A groove 32 substantially parallel to the rotating shaft 2 is formed on the inner surface of the central portion of the lid 31 of the inlet 29.
A fountain nozzle 42 whose opening and closing is controlled by a valve 42' is provided in the rotary shaft 2, 13, 13' after the mashing operation is completed and the material is collected from the discharge port 33 into the receiving box 38. By opening the valve 42' and injecting water into the mortar body 1 from the fountain nozzle 42 while rotating the mortar body 1, fine materials in the mortar body 1 can be washed and collected from the discharge port 33.

In addition, as in the illustrated embodiment, the material input port 29 is connected to the mortar body 1.
When the material input port 29 is installed directly above the center line of the material input port 29, a washing water fountain mechanism consisting of the groove 32 and the fountain nozzle 42 is provided in the input port lid 31 as described above.
If it is provided at a position shifted to the left or right from the position directly above the center line of the mortar body in Fig. 2, the concave groove 3
2 is formed on the inner wall of the circumferential surface of the mortar directly above the center line of the mortar,
A fountain nozzle 42 should be provided in the groove 32, and the method and function for cleaning the inside of the mortar body 1 in this case are the same as in the illustrated embodiment.

Reference numeral 24 denotes a cooling space formed outside the circumferential surface 22 of the mortar body 1 at an intermediate portion between the circumferential frame edges 25 and 26 of the mortar body 1; A cooling space formed at 28,
The inside of the mortar body 1 is cooled by flowing a liquid cooling medium such as cooling water into the cooling spaces 24 and 27 or by filling a solid cooling medium such as ice or dry ice during the mashing operation. It is now possible to prevent the temperature of materials from rising.

The shape of the abutment body 1 is not limited to the cylindrical shape as shown in the illustrated embodiment, but may also be a truncated cone shape, a partially truncated cone shape, a dish shape,
Any shape can be adopted, such as a spherical shape, an elliptical cylindrical shape, a barrel shape, etc., and the mortar body 1 having any of these shapes is fixedly supported on a frame while being placed horizontally or slightly inclined.

In the above configuration, materials such as minced fish are input into the mortar 1 through the input port 29, various additives are also input as required, the lid 31 is closed, and the motors 19 and 19' are rotated. The rotating shafts 13 and 13' are both rotated clockwise, and the rotating shaft 2 is also rotated counterclockwise by rotating the motor 6. A crushing rod 14' is attached to the rotating shaft 13, and a cutter 1 is attached to the rotating shaft 13'.
4", the cutter will fit the blade 14.
At the same time as cutting and crushing the material with a'', the crushing rod 14'
crushes the material, and at the same time the scraping member 12 also rotates to thoroughly stir and mix the material being cut, crushed, and crushed to quickly and evenly cut, crush, and crush the material.
Mixing and mashing are performed.

Once sufficient grinding, mixing, and mashing have been achieved, the lid 35 is opened by pulling the grip handle 34. Then, as the scraping member 12 rotates, the material flows out from the discharge port 33 and is collected into a receiving box 38 received below the mortar body.

In the above-mentioned work, the cutter shaft side of the rotary shafts 13 and 13' for mashing is 500 to 4000 rpm, the shaft on the mashing rod side is 250 to 2000 rpm, and the scraping rotary shaft 2 is approximately 20 to 400 rpm.
A rotation of about 100 rpm is appropriate.

The number, size and thickness of the cutters, length and diameter of the crushing rod have a great deal to do with the torque and heat generation of the rotating shaft, so they should be selected appropriately to match the type and purpose of the material.

The rotational direction of the scraping shaft 2 can be freely selected depending on the data, and the rotation speed can also be freely selected within the above range.

Sub-materials and various additives may be added at the same time as the material is input as mentioned above, or they may be added at the same time as the material is crushed, mixed,
It may be added at an appropriate time during the mashing operation.

When manufacturing fish paste products, it is desirable to keep the temperature of the material at a low level during mashing to prevent slurry, but in the present invention, the cooling spaces 24 and 2
The temperature of the material can be easily maintained at a low level by passing a liquid cooling medium such as cold water through the tube 7 or filling it with a solid cooling medium such as ice or dry ice.

In addition, the temperature inside the mortar body 1 can be checked at all times using the thermometer 43, and for example, if the rotation of the rotating shaft is high, the temperature inside the mortar body 1 may be at a predetermined temperature (for example, about 10°C).
It is desirable to automatically turn off the switch 44 and stop the motors 18, 18', 6 when the value exceeds the limit. In the case of overtorque, it is desirable to automatically stop it in the same way as above.

Generally, the temperature is kept constant and the time is stopped by the action of a time switch.

Furthermore, depending on the type of fish paste product, it may be crushed, mixed,
Although it is often desirable to perform mashing in a near-vacuum state, in the present invention, after the material is put into the mortar body 1, the interior of the mortar body 1 is sealed, and the air inside is extracted from the air extraction port 45, and then the vacuum gauge The above request can be satisfied by a method that suits the data, such as starting operation after confirming that the inside of the mortar 1 has reached a predetermined degree of vacuum in step 46, or creating a vacuum state during operation.

Depending on the type of material, it may be crushed, mixed, or
There may be cases where it is better to perform a crushing operation, but in that case, the interior can be easily pressurized by supplying air pressure from the air extraction port 45.

The processing status of the material during the above-mentioned material crushing, mixing, and crushing operations can be visually checked through the door 39.

After the mashing is completed as described above, the material is taken out from the discharge port 33, and then a container for washing water is placed under the discharge port 33, and washing water is sprayed from the fountain nozzle 42 on the upper part of the mould, and the rotating shaft 2, 13, 13' and mortar body 1
Wash the inside and stop the motors 19, 19', 6.

The interior of the mortar body 1 can be checked thoroughly by opening the door 39 to see if it is in a sanitary state, and can be kept clean at all times.

In the above embodiment, there are two rotary shafts for mashing, but if there is only one rotary shaft for mashing, rotating in one direction will cause cutting and crushing action by the cutter blade, and rotating in the opposite direction will cause cutting and crushing. It is also possible to use a structure in which the material is struck with the thick part of the back.

In order to improve the stirring and mixing function of the material by the scraping member 12 and to improve the guiding function to the discharge port 33 when discharging the material, an arm 10 and a scraping blade 1 are provided.
1 can also be given an appropriate twist or bend.

As mentioned above, this device can work even with small quantities of materials, and can efficiently and efficiently combine parts suitable for each situation from small quantities to large quantities. It is something that you can work on.

The opening and closing of the input port at the top of the mortar body and the opening and closing part of the discharge port at the bottom of the mortar container can all be automatically opened and closed using an oil cylinder, etc., according to a timer, and cleaning with a fountain nozzle can also be automated. .

Effects of the Invention As described above, according to the present invention, materials can be efficiently crushed, mixed, and crushed in an extremely hygienic manner, and if necessary, crushing, mixing, and crushing can be carried out under vacuum, pressurization, or low-temperature conditions. This can be easily carried out and can bring about great practical effects.

It goes without saying that the apparatus of the present invention can be applied not only to fish paste products but also to the crushing, mixing, and crushing processes of all types of materials.
