The invention relates to a nozzle arrangement, an apparatus and a method for the metered, shaping output of mass bodies of pumpable, viscous or doughy masses and the like

According to the state of the art, pumps for conveying viscous, pumpable masses, such as doughs, creams, foamed creams, ice creams, etc., are known in food technology, in which a mass feed for the metered discharge of the masses is closed at regular intervals in order to supply a mass body form. A disadvantage of conventional devices is that the viscous mass adheres to the closing device at least partially when closing and thus the mass body has no clearly defined cutting edge, but a thread-like extension. This effect occurs in particular in soft, flowable compositions with relatively low viscosity.

Furthermore, it is known in the prior art, the mass supply to

Promotion of the mass for the separation of a mass body by means of air pressure freizublasen. A disadvantage of this device is that the air pressure acts essentially in the output direction of the mass body. Although by blowing out the

Forming a thread-like extension of the mass body avoided. The disadvantage, however, is the effect that the air pressure deforms the portion region of the mass body uncontrolled and in particular bulges inward.

Object of the present invention is to provide an apparatus and a method for the metered, shaping output of mass bodies of pumpable, viscous masses, which allows accurate metering, accurate shaping and accurate cutting of the mass body of the mass. It is another object of the invention to provide a simple, inexpensive and maintenance-free device.

All these tasks can be subsumed under the task of efficient, metered, shaping output.

The object according to the invention is achieved in that a gas nozzle arrangement is provided for discharging one or more gas jets directed at the mass located in the separation area and for separating the mass body by forming.

In an advantageous manner, it can be provided that the gas nozzle arrangement comprises a gas nozzle which is used to deliver a self-piercing gas jet

is arranged so that the gas nozzle arrangement comprises a plurality of gas nozzles, which are adapted to deliver against each other directed gas jets, that the direction of the gas jet in the region of the gas nozzle exit from the discharge direction of the mass fed from the mass supply into the separation area mass that the gas jet or the gas jets transverse to the output direction of the mass run and / or that the gas jet or the gas jets are cross-shaped or the shape of a

Double cones, a hyperboloid, a single-walled hyperboloid, or one

Follow rotational hyperboloids.

Further advantageous features are that the mass in the separation area is moved as a free jet, that the gas jet (s) are directed in the separation area as a free jet outside the mass supply to the mass and / or the mass body, wherein the free jet of the gas jet is guided by a jet or guided by a wall, that the mass, the separation region and / or the mass supply is surrounded by a gas nozzle outlet or by a plurality of gas nozzle exits, that the gas nozzle outlet in

Substantially annular in the region of the separation area around the mass extends around, that the gas nozzle has a direction of gas nozzle outlet tapered section for focusing the gas jet and / or that the gas nozzle outlet is designed as an annular gap, in particular as an uninterrupted annular gap.

According to further advantageous embodiments can be provided that a distribution chamber is provided for distribution of compressed gas, which is connected to the pressure supply line and with the gas nozzle, that the distribution chamber extends annularly around the mass supply line, that the mass supply to influence the mass flow of the mass a closure is partially or completely closable, that the closure comprises a movable piston, that the closure and / or the piston is arranged in the mass supply line and / or that the piston has a sealing area, which is suitable for closing the mass supply to a sealing area of the mass supply can be brought into operative contact.

Furthermore, the object of the invention is achieved by a device for the metered, shaping output of mass bodies of pumpable, viscous masses such as doughs, edible creams, ice creams and the like, which is characterized in that one or more nozzle arrangements according to the invention are provided.

The device is preferably characterized in that a

Transport surface for transporting the separated from the mass forming

Mass body is provided that a plurality of nozzle arrangements are provided, which are arranged side by side in the region of the transport surface that a compressor for compressing a gas such as air is provided that the compressed gas passed via one or more pressure supply lines to the nozzle assemblies and in particular to the gas nozzle assemblies is, and / or that means for controlling the gas mass flow such as a control valve, a Flow regulator and / or a pressure regulator are provided.

Furthermore, the object of the invention is achieved by a method for metered, shaping output of mass bodies of pumpable, viscous masses, comprising the following steps: a mass is conveyed in a mass supply to a mass exit opening, the mass is through the

Mass exit opening from the mass supply conveyed into a separation area, the mass is in Trennbe rich cut off from a gas jet and formed, so that a mass body is formed.

The method preferably comprises the steps that the mass outside the

Nozzle assembly is cut and shaped by the gas jet that for separating a mass body from the mass, the mass and the gas jets meet as free jets and / or that the gas jet or the gas jets transversely to the discharge direction of the mass and / or substantially cross-shaped.

According to the present invention, the device is suitable for metering and shaping one or more mass bodies. For dosing, the mass flow of the mass in selectable and / or predetermined intervals

Mass body of desired size and / or desired mass. By appropriate control of the device, the size and weight of the dispensed

Be controlled mass body.

For shaping output, the invention provides that the mass is cut off by a closure and / or a gas nozzle. In particular, the gas nozzle is adapted to retighten thread-like extensions of

Prevent mass body to the supply line. According to the invention, the mass body should travel along a desired contour, e.g. be formed rounded. This is

in particular solved by the fact that a gas jet is used, the

Cut off mass body from the mass or the closure and / or shape it. The direction of the gas jet is preferably transverse to the output direction of the mass body. By the nozzle arrangement according to the invention comprising a gas nozzle arrangement and by the device according to the invention comprising a nozzle arrangement, the cut surfaces or the cutting areas of the mass bodies are given the desired shape.

As the direction of the gas jet is the direction of a current thread of the

Gas flow of the gas jet meant. In annular arrangement of

Gas nozzle assembly has or the gas jets on several directions. Preferably, the direction of each gas jet differs at least on exit from the gas nozzle from the output direction of the mass or the mass body in

Separation area.

As transverse to the output direction, it is defined that the gas jet for the most part does not run parallel to the output direction of the mass. In particular, transverse means a direction in which a cutting off of the mass body is made possible by the mass.

Preferably, the gas nozzle assembly and the gas nozzle are operated with air. For this purpose, a compressor is arranged, which compresses air and passes via a gas supply line to the gas nozzle arrangement.

The cutting and shaping of the mass body is done in a preferred manner by the gas jet, which is present as a free jet. As cutting or shaping by a free jet, a process is referred to, in which the deformation of the mass takes place substantially or completely through the gas jet. In contrast to blowing out a tube, in the present invention cutting takes place outside the nozzle and outside the bulk supply line. For this purpose, the mass in the separation region, ie in that region in which the mass leaves or left the mass supply, is cut off as a free jet of the gas jet (s), which likewise emerge from the gas nozzle as a free jet. The free jet of the gas can thereby beam-guided, so essentially without the influence of solid objects or

Wall guided, so be performed guided along a solid surface.

The gas nozzle arrangement can be annular, ring segment-shaped or

be arranged in sections around the exit area or the mass around. For uniform distribution of the compressed gas along several or an annular nozzle, a distribution chamber may be provided, into which the Compressed gas, coming from the compressor, is introduced. In this distribution chamber, the compressed gas is distributed and passed for example via holes or directly to the nozzle or to the nozzles of a nozzle assembly.

By an oblique, annularly arranged nozzle is a raumkörper- or

generated space-shaped gas jet. This follows, for example, a double cone, a hyperboloid, a single-shell hyperboloid or a rotational hyperboloid, wherein the axes of symmetry of the geometric shapes are substantially parallel or congruent with the output direction of the mass.

Furthermore, it can be provided according to the invention that two or more gas nozzles are arranged so as to be directed around the separation area. By the

Symmetrical arrangement, a lateral transverse deformation of the mass body can be prevented.

Subsequently, the invention will be further described by means of concrete embodiments.

Device according to the invention in a first position.

Fig. 2 shows a sectional view of the nozzle arrangement of a device according to the invention in a second position.

Fig. 3 shows a device according to the invention in a third position.

Fig. 5 shows a schematic view of a device according to the invention.

Fig. 1 shows an embodiment of the device according to the invention, in particular the nozzle assembly 32, with a ground lead 4 for supplying a mass 2 in an output area 5. In this case, the mass 2 through the mass lead 4 by a mass outlet 38 in the separation area 1 1 promoted. In that

Output area 5, a gas nozzle assembly 39 is provided. The

Gas nozzle arrangement 39 comprises one or more gas nozzles 6. The present gas nozzle 6 has a tapered, wedge-shaped section 10, which opens into the gas nozzle outlet 9. In a preferred manner, the gas nozzle is designed to taper in the direction of the gas nozzle outlet 9. For supplying the gas, in particular compressed air, a pressure feed line 12 is provided. This opens in the present embodiment in a distribution chamber 13 which extends annularly around the mass supply line 4 and is connected at one, at several points or directly to the gas nozzle 6. In the present embodiment are several

Distributor bores 18 are provided which extend from the distribution chamber 13 into the gas nozzle 6. The device has the separation area 1 1 in the output area 5. In this area, the mass 2 exits from the mass supply 4 and is there in a preferred manner by the inflowing mass or by gravity as a free jet advances. The direction of movement essentially follows the output direction 3. In the present embodiment of FIG. 1, the mass lead 4 also has a tapered region 19. In this conically converging region, if necessary, a deflection of the dispensing direction 3 is given. However, the promotion of the mass 2 and the mass body 1 follows in the

Essentially the illustrated output direction 3.

At the tapered portion 19 of the ground lead 4, the sealing area 17 of the ground lead is provided. Further, a closure 14 is provided, via which the mass supply 4 and the promotion of the mass 2 can be influenced or stopped. For this purpose, the closure 14 has a sealing region 16. The

Sealing region 16 of the closure 14 and the sealing region 17 of the mass supply 4 can be brought into operative contact via a suitable control to the

Promotion of mass 2 to stop or at least reduce. In the present embodiment, the shutter 14 is performed by a piston 15 disposed in the mass supply 4. The piston 15 is surrounded in the illustrated open position along its lateral surface of the mass 2 or lapped. By axial displacement, in particular by displacement along the dispensing direction 3 in the direction of separating area 1 1 or direction output area 5, the sealing region of the closure can be brought into operative contact with the sealing region of the ground supply become. For this purpose, the piston 15 has a conical, conical sealing region 16. The mass supply 4 has a conical, tapered conical

Sealing area 17 on. By an annular, linear or surface contact of the two sealing regions 16, 17, the promotion of the mass 2 can be stopped or

to be interrupted.

In the illustrated position of FIG. 1, the mass 2 is conveyed into the dispensing area 5. The piston is in retracted position. The closure 14 is thus opened and a promotion of the mass 2 in the output area is possible. The gas nozzle 6, the annular chamber formed as a distribution chamber 13 and the

Pressure supply line 12 are filled with a gaseous medium, in particular with air. According to the position in Fig. 1, the pressure of the gaseous medium in the gas nozzle 6 corresponds to the ambient pressure. There is thus essentially no gas exchange between the gas nozzle 6 and the outside area, in particular the dispensing area 5 or the separation area.

The mass 2 is bulged in the discharge area 5 and can be applied, for example, to a moving or fixed surface or a carrier body. From this bulge running area of the mass body 1 is formed and shaped by the procedural steps.

Fig. 2 shows the device of Fig. 1, but in a second position. In this position, the closure 14, in particular the piston 15, is displaced in the direction of the dispensing area 5 or in the direction of the mass outlet opening 38. In this case, the sealing region 16 of the closure 14 is pressed onto the sealing region 17 of the mass supply line 4. Due to the flat, linear or annular system of the two sealing regions 16, 17, the mass supply line 4 is closed and the promotion of the mass 2 of

Mass supply 4 interrupted in the separation area 11. In the illustrated position, compressed gas flows through the pressure feed line 12 into the distribution chamber 13. The distribution chamber 13 extends in a substantially annular manner around the mass supply line 4. Furthermore, the distribution chamber 13 distribution holes 18. The

Manifold bores 8 connect the distribution chamber 13 to the gas nozzle assembly 39 or the gas nozzle 6. Through the distribution bores 18, the gas flows into the

Gas nozzle 6, further through a tapered portion 10, to subsequently as Gas jet 7 or exit as gas jets 7 through the gas nozzle outlet 9. The gas jet 7 is directed to the mass 2 or a region of the mass body 1. The focused gas jet 7 is directed into the separation region 11 such that it is possible to cut off the mass body 1, preferably transversely to the discharge direction 3.

In the illustration of FIG. 2, the mass body 1 has an extension 20. This thread-like extension 20 is formed by cohesive forces and / or adhesion forces in the viscous mass 2.

The representation of FIG. 2 corresponds to the beginning of the cutting process by the gas jet 7.

Fig. 3 shows the same device as Figs. 1 and 2, but in a third position. The device in turn comprises a mass supply line 4 for feeding a mass 2 into an output region 5. In the position of FIG. 3, the mass supply line 4, in particular in the tapering region 19 of the mass supply line 4, through the

Closure 14 closed. Thus, the promotion of the mass 2 is stopped. From the mass supply 4, the mass at least partially leaked to a

To form mass body 1. This mass body 1 is cut off or separated according to the invention by the gas nozzle arrangement 39 and the gas jet 7 or the gas jets 7. For this purpose, compressed gas, in particular air, by a

Pressure supply line 12, optionally a distribution chamber 13, passed with connected distribution holes 18 in the gas nozzle assembly 39. The gas nozzle arrangement 39 is designed such that the gas jet transversely to the discharge direction 3 of the

Mass body 1 or the mass 2 meets the mass 2. In the output area, in particular in the separation area 1 1, the mass 2 is present as a free jet. This free jet is cut off by the gas jet 7 and / or shaped shaping. In the present embodiment, the gas nozzle assembly 39 is arranged such that the gas jet is guided in a substantially conical manner on the mass 2 and / or the mass body 1. The direction of the gas jet 7 thus essentially follows one

Bicone 21, which is shown schematically as a dotted line. Due to flow conditions, the direction of the gas jet 7 may also be similar or follow a hyperboloid 22, in particular a single-shell hyperboloid or a hyperboloid of revolution. By the energy of the gas jet 7, in particular by the kinetic energy of the moving gas, the mass body 1 is separated. The extension 20 is cut off or separated by the special nozzle geometry and the special direction according to the invention of the gas jet and deformed into a desired, shaped sectional surface 23. This is executed in the schematic representation of FIG. 3, for example, as a rounded cut surface 23. The tightening of thread-like extensions is prevented.

In the illustration of FIG. 3, a mass residue 24 remains on the closure 14 after the cutting process. This sticks by adhesive or cohesive forces on the closure 14th

By suitable shaping of the closure 14 of a not shown

Embodiment, however, the remaining of a residual mass 24 can also be prevented. For example, by a round, bulged configuration of the tip of the closure 14, the gas jet at the tip of the closure 14 along strip to lift the mass remainder 24 of this. In this alternative

Embodiment, the gas jet is also present as a free jet. However, the gas jet sweeps along the contour of the gas nozzle and along the contour of the closure 14 along. The free jet is preferably wall guided in this embodiment. Furthermore, the mass body is separated from the closure by the gas jet and not, as described in further embodiments of the mass. The separation of the mass forming the mass body happens through the closure.

Preferably, in the method according to the invention, the positions 1, 2, 3 of Figures 1, 2 and 3 in ascending order.

4 shows a detailed representation of the device according to the invention, in particular in the separation area 1 1. The device comprises a gas nozzle 6 for emitting a gas jet 7. The gas nozzle 6 has a tapered portion 10. This tapered portion causes the focusing of the gas jet 7. However, it is also the spirit of the invention, not to provide a tapered portion and the gas nozzle 6 substantially straight, with parallel or open walls to design. In the gas nozzle 6 distribution holes 18 open. About this gas flows from the distribution chamber 13 into the nozzle 6. According to the 4, the nozzle 6 is designed annular and / or conical. However, it also corresponds to the idea of the invention, the nozzle

to design interrupted. Thus, the gas nozzle assembly 39 divides into a plurality of gas nozzles, which are arranged, for example, along the circumference of the separation region 11. The provision of two cross-shaped counteracting gas nozzles, which give substantially the same sectional view as the sectional view of FIG. 4, corresponds to the inventive idea.

The gas nozzle 6 opens into the gas nozzle outlet 9, from which the gas can escape. For this purpose, in a preferred manner, the gas in the free separation region 1 1. Also, the mass 2 exits in the form of a free jet from the mass supply line 4. According to the

present embodiment, the gas nozzle outlet 9 in the immediate vicinity of

Separation area 11 is arranged.

The mass supply 4 is essentially formed by a cladding tube 25, which extends in one or more parts to the mass exit opening 38 and to the separation area 1 1. Toward the separation region 1 1, the cladding tube 25 has a tapering region 19. The outer wall 26 of the cladding tube 25 is carried out obliquely or conically in the direction of the separation region. The outer wall 26 forms a first wall of the gas nozzle 6 in this area. The second wall is formed by the inside of the nozzle shell 27. The nozzle shell 27 is connected to the cladding tube 25 and has a cavity to this, which corresponds to the gas nozzle 6 substantially. The inside of the nozzle shell 27 is also tapered or conical and forms the second nozzle wall of the gas nozzle 6. The inner wall of the nozzle shell 28 and the outer wall of the cladding tube 26 are thus arranged at a certain distance from each other.

The two walls 26 and 28 preferably approach one another in the direction of the gas nozzle outlet 9. As a result, the tapered portion 10 is formed.

The cladding tube 25 is connected to the main body 30. Also connected to the main body 30 is the chamber ring 29. In this case, the chamber ring 29 a

Inner diameter, which is greater than the outer diameter of the cladding tube 25 in the region of the chamber ring 29. Thus, an annular gap or an annular chamber between the chamber ring 29 and the cladding tube 25 is formed. The cavity thus formed is further bounded by the main body 30 and the nozzle shell 27. The cavity essentially forms the distribution chamber 13. In the chamber ring 29, an opening for connecting the pressure supply line 12 is provided. Via the pressure feed line 12, the gas can be conducted into the distribution chamber 13 and via distributor bores 18 into the gas nozzle 6. The manifold bores are provided in a portion of the nozzle shell 27 in the present embodiment. However, it is well within the spirit of the invention to perform these holes as exemptions in other elements of the device according to the invention. Further, it is also within the concept of the invention to make the chamber ring 29 and the nozzle shell 27 as one body.

To control and regulate the gas pressure, a buffer, a pressure regulator, a pressure gauge, an air heater and / or a flow regulator may be provided after the compressor. About these control options, the

Gas flow can be precisely controlled and / or regulated. In the arrangement of nozzles directed against one another or else in the case of conically arranged nozzles, part of the gas jet can be deflected in the discharge direction 3 due to dynamic effects of the gas jet. To the negative effect of uncontrolled deformation of the

To avoid mass body 1, in such a case, an exact adjustment of the control and / or control parameters of the gas flow is necessary. So is depending on

geometric configuration of the gas nozzle 6 to select the gas mass flow such that the deflected in the discharge direction 3 partial gas mass flow in the region of

Mass body has a speed that causes no uncontrolled deformation of the mass body. Advantageously, the velocity of the gas mass flow deflected in the discharge direction in the region of the mass body is only slightly greater than or equal to the output speed of the mass body

Mass body 1.

Thus, according to one embodiment, the gas pressure in the pressure feed line 12 may be about 0.1 to 3.5 bar. The gas volume flow is variable in this case from about 0.1 to 125 liters per minute and per gas nozzle. The opening time of the valve, during which the gas nozzle 6 is flowed through, can be between 0.01 and 2 seconds.

Also, the gas nozzle 6 has, similar to the distribution chamber 13, a certain

Cavity volume on. This void volume serves in particular for the distribution of the Pressure. The gap width of the gas nozzle outlet 9 may, for example, be between 0.1 to 0.8 mm in the illustrated embodiments. In particular, the required gap width depends on the viscosity of the mass to be cut.

The gas jet 7 is preferably conducted transversely to the discharge direction 3 in the direction of mass 2. For example, angles of 90 ° to 45 ° are suitable for this purpose. This angle is measured between the direction of the gas jet 7 at the gas nozzle exit 9 and the discharge direction 3. Preferably, the gas jet, as shown in the figures in

Movement direction of the mass inclined.

5 shows a device according to the invention for the shaping discharge of mass bodies from, for example, pumpable, viscous masses comprising a nozzle arrangement 32 according to the preceding description and in particular according to the preceding FIGS. 1 to 4. Furthermore, the device according to the invention comprises a transporting surface 31, which in the present embodiment when

Belt conveyor is executed. Furthermore, the device comprises a pressure regulator 33, a pressure gauge 35, a flow regulator 34, a gas valve 36 and a

Gas distributor 37.

Compressed gas is supplied from a compressor, not shown, coming via a controllable valve 36. Along the pressure supply line 12 are a pressure regulator 33 for controlling the inflowing pressure and optionally a pressure gauge 35 for measuring the pressure and a flow controller 34 for controlling the

Gas mass flow provided. The gas mass flow which can be varied and / or adjusted by means of these means is introduced into a gas distributor 37. This gas distributor 37 essentially corresponds to a pressure buffer store, which allows a plurality of openings for distributing the compressed gas to a plurality of nozzle arrangements 32. In the present illustration, the gas distributor 37 has five outgoing

Pressure supply lines 12, each leading to a nozzle assembly 32. Thus, the illustrated embodiment of the device according to the invention is adapted to simultaneously operate five nozzle assemblies 32 and thus simultaneously five

Output mass body 1 shaping. As noted in the foregoing description, the mass bodies 1 are deposited on a transport surface 31 and transported away. The mass bodies are schematic in the present FIG shown. The nozzle assemblies are juxtaposed according to the present embodiment. This means that they are arranged essentially along a straight line or along a region which runs transversely to the conveying direction of the mass bodies on the conveying surface. This enables a parallel and / or simultaneous output of several mass bodies.

Subsequently, the method according to the invention will be further described.

In a first step, the mass 2 through the mass lead 4 direction

Output area 5 passed. The mass may be conveyed, for example, by a mixer and a pump arranged thereafter or in front of it. The mass 2 flows into the discharge area 5 and passes through a mass exit opening from the

Mass supply 4 off. The promotion of the mass happens as long as the delivery by the pump is maintained or as long as the closure 14 of the device is open. The shutter 14 may be actuated via a suitable controller to close the bulk supply 4. If the desired amount of mass 2 leaked, the closure 14 is closed via the control. For this purpose, a piston 15 is moved in the output direction 3 in the present embodiment. The sealing region 16 of the closure is doing with the sealing region 17 of

Mass supply brought into operative contact to close the mass supply 4.

The leaked mass 2 and / or the mass body 1 is subsequently applied, for example, to a conveyor belt, to a stationary surface, to a moving carrier body or a similar arrangement. Preferably, the device according to the invention to the surface to which the mass 2 is applied, a certain distance. In this area is the mass 2 and / or the

Mass body 1 as a free jet before. If the mass supply 4 is closed by the closure 14, a valve is opened in order to conduct gas via the pressure feed line 2 into the gas nozzle arrangement 39. For this purpose, the compressed gas is distributed in a first step in a distribution chamber 13, in a further step on

Manifold holes 18 passed into the gas nozzle 6, where appropriate, distributed once more and finally a tapered portion 10 and the

Gas nozzle outlet 9 preferably spent focused. The resulting

Gas jet 7 or the resulting gas jets 7 are on the mass 2 or directed to the mass body 1 to allow the desired shaping output or the forming separation. In this case, gas jets are led outside the mass supply via a gas nozzle arrangement to the mass. Preferably, the gas jets are directed to the mass transverse to the mass output direction. In this case, the gas jets or the gas jet can be output from a plurality of nozzles or from a nozzle. To improve the shaping can be inventively provided that the gas jets are directed against each other directed to the mass. For this purpose, cruciform gas jets, conical gas jets or other forms of the course of the

Gas jets, where by the gas jets, a substantially symmetrical space body is formed. In particular, this symmetry is advantageous, as a lateral deformation of the mass body is avoided in the cutting area. The free jets, in particular the free-jet gas jets, can thereby

beam-guided or wall-guided. In wall-mounted gas jets, the gas jets sweep along a solid object, such as a cone.

If the mass body 1 is separated from the mass 2 or by the device, the closure 4 is opened again to form a further mass body 1. Subsequently, the above steps are repeated.

According to the present invention, a plurality of devices according to the invention, in particular nozzle arrangements, can be arranged side by side along a moving conveying surface. Several nozzle arrangements can be supplied by a compressor with compressed gas.

The device according to the invention and the method according to the invention are suitable and / or are adapted to be used in-line in an industrial production plant for food products. Examples of products are elongated bakery products with rounded ends, chocolate bars, fillings of

If desired, the device according to the invention can also be used for the shaping dispensing of doughs, edible creams or ice creams. Reference numerals:
