Output can be achieved, it is necessary that the product to be filled has a uniform Has density in order to ensure an even and constant weight of the formed portions of the product to ensure. Certain foods, such as meat, can have a sufficiently uniform density can be achieved by chopping the product very finely. Though chopping up the starting product is in no way disadvantageous in the production of certain goods, such as mince dumplings or meat or fish pastes, there can be an insurmountable difficulty in making other meat or fish Fish products or products from another food, if this is one of them have a peculiar fibrous structure. When dosing chicken when preparing canned soups or chicken patties * in which the product contains whole pieces of meat For example, it is desirable that the chicken be affected as little as possible. "Impaired as little as possible" is understood to mean that the pieces of meat are theirs as much as possible should retain the original fibrous structure and be recognizable as such by the end user should.

To achieve this object, according to the invention, a device for producing volumetrically subdivided ones is provided Proposed food portions which have a funnel for receiving the pieces of food, as well as a filling channel, which is then connected to

The funnel is arranged and suitable for the food to pick up objects from the funnel, as well as a separating wedge, which can be moved in one direction, which runs obliquely to the axis of the filling channel to move between the in the transition zone between the Hopper and the filling channel located food-3 do eic e to push the inside of the filling channel compress the pieces of food that are located and then close off the filling channel as part of its wall, furthermore a piston which is arranged in the filling channel and which is suitable for holding the pieces of food in the filling channel further compressing to form a contiguous bar of substantially constant view and to form cross-sectional dimensions and means for dividing this bar into individual portions.

The means for dividing the food bar into individual portions preferably comprise a Weßkamner arrangement, which has an overall cross-section which, geometrically, is essentially the cross-sectional dimension of the filling channel, wherein the measuring chamber arrangement is arranged so that it is the end of the bolt can receive when it is pressed into it by the piston and furthermore the measuring chamber arrangement is movable transversely to the filling channel in order to separate at least part of the food from the bar.

The power switch assembly may have a plurality of thin partitions have, which are arranged in planes running parallel to the bolt and the measuring camera arrangement

Subdivide into a number of individual measuring chambers. These partitions should be made so thin that their cross-sectional area compared to the total cross-sectional area of the bolt is insignificant. In this way, the cross section of the bolt in a number of equal portions can be divided.

Advantageously, the piston is arranged so that the pressure on the food bar during the Transverse movement of the measuring chamber arrangement is maintained in order to separate the individual portions from the handle. This ensures that the density of the material remains constant during the subdivision.

Preferably a pressurizable ejector is provided to eject the individual portions under pressure from the measuring chamber arrangement, the arrangement being such that the ejectors remain actuated until the measuring chamber arrangement has completed its retrograde transverse movement in order to receive a further part of the end of the hiegel. This prevents ready material from penetrating the measuring chamber assembly before it is fully in its receiving position, whereby the occurrence of shear stresses in the compressed bar is reduced to a minimum.

The filling channel preferably has a rectangular cross-section to form a rectangular bar , and the separating channel is shaped so that it forms part of the flat wall of the filling channel.

Each of the in the Pig. 1 to 5 shown embodiments of the device comprises a feed hopper 1, which is rectangular in plan and tapers towards its lower end in vertical section. Bas upper The end of the funnel 1 is open and forms a filling opening. The rectangular bottom 2 of the funnel is also open and ends in a filling channel 3 with a rectangular cross-section. The width of the upper opening of the funnel is equal to the width of the bottom 2 of the funnel. The connection between the Inside the feed hopper and the filling channel 3 can be opened and closed by means of a separating wedge, which is formed by a slide 4 »the is rectangular in plan and trapezoidal in elevation. This slide 4 is slidably mounted in a guide 5, the longitudinal axis of which is at an acute angle

with respect to the longitudinal axis of the filling channel 3 includes. The front edge of the slide 4 is flattened to form a knife edge 6, so that the slide in the position in which he establishes the connection between the interior of the feed hopper 1 and the AbfUllkanal 3 interrupts, forming part of the upper wall of the channel 3. The slide 4 is fixed to the piston rod T connected to a pneumatic cylinder 8 which is attached to the frame 9 of the device.

The filling channel 3 is closed at one end by a piston 10, which with the piston rod 11 is a second pneumatic cylinder 12, which is likewise attached to the frame 9 * In the embodiments shown in FIGS. 1 to 4, the channel 3 ends at the other TSnds with an outlet opening 13 # on which a block 14 rests, which by means of a pneumatic cylinder 19 attached to the frame 9 and is movable from.

The block 14 comprises a recess 16, the cross section of which corresponds to the cross section of the filling channel 3 and in which a number β or thin, vertical partition walls 18 are arranged, which the recess 16 in subdivide a number of equal measuring chambers 19 (FIG. 2). In the examples shown, the Partitions 13 the recess 16 in six Meflkammern.

An ejector device that can be acted upon by pressure with a bar 17 is arranged in the recess 16, the bar 17 having a number of slots 20 which are correspondingly assigned to the partition walls 10

are so that calibrate the partitions 1b in each position of the beam 17 extend into the slots 20. The depth of the slots 20 is chosen because the ends of the Slots 20 abut the rear edges of the partition walls 18 when the beam 17 is in its ejection position has reached. The pitch division of the beam 17 is shown in FIGS. 1, 3 and 4 in broken lines. posed.

On these catfish form the separation of the beam 17 between the slides 20 each have a piston assigned to a respective measuring chamber 19, the rear wall the outer surface 16 is provided with an opening 21 to which a compressed air line can be connected can.

The mode of operation of those shown in FIGS. 1-4 Device is as follows

When the feed funnel 1 has been filled with the pieces of food to be fitted into cans via its upper opening, the cylinder 6 is actuated so that the sole 4 opens the connection between the interior of the feed funnel and the channel 3. However , it is also possible to fill the feed hopper 1 in the open stall as the slide 4 lets the skins fall directly into the channel 3 from the feed material. As soon as the channel 3 is filled no further below the weight of the feed funnel 1, the cylinder 8 is actuated in order to move the bottom but also into the closed position. During the start of work ««

The knife edge 6 of the slide 4 pushes itself between the pieces of food, while the amount of pieces of food located below the flat end of the slide is compressed to a certain extent. Since the flattened end of the slide 4 moves not only downwards but also to a greater extent forwards during the closing movement, the closing movement of the slide exerts more of a splitting effect than a cutting effect on the mass of the pieces of food. The pieces of food in the channel 3 tend to assume such a position that the direction of their fibers runs parallel to the longitudinal axis of the channel. When the slide 4 has reached its closed position shown, the pneumatic cylinder 12 is actuated so that the piston 10 compresses the pieces of food located in the channel 3 with a specific pressure to form a bolt. During this additional pressure movement, the air contained between the pieces of food escapes behind the slide 4 and between the facing surfaces of the housing of the device and of the block 14. The pieces of food in the channel are thus pressed together to form a homogeneous bar which no longer has any cavities. ι

When the block 14 is in the position shown in FIG position shown in full lines, will dae The end of the bolt is pressed into the measuring chamber 19, with the opening 21 is then in connection with the ambient air ' stands and the Baiken 17 moves so far back under the influence of the pressure exerted by the bolt until it rests against the rear wall of the recess.

Since the partition walls consist of thin plates, the cross-section of the Hiegel remains when the measuring chambers are filled essentially constant, whereby damage to the pieces of food is kept to a minimum.

After the measuring chambers 13 have been completely filled, the cylinder 15 is actuated, which the block 14 moved to the position shown in broken lines in the drawing. This will the bolt separated in the plane which is indicated in the figure by the line II-II, whereupon the outlet opening of the channel 3 is closed by the plate 22 of the block. If the block 14 is interrupted in Has reached the position shown lines, compressed air is introduced through the opening 21, so that the bar 17 is moved to its ejection division and the block-shaped food is ejected as it is is shown schematically in the drawing.

Since the pneumatic cylinder 12 is continuously actuated both during filling and during ejection remains, the beam 17 is held in its ejection position after emptying the measuring chambers by the air pressure at the port 21 is maintained until the cylinder 15 passes the block 14 in full lines has moved back the starting position shown. The air pressure supplied through opening 21 is high enough in order to prevent the bar 17 from getting into the measuring chambers due to the dead center bar in the channel 3 exerted pressure to return to its starting position «as soon as the recess 16 with the channel 3 is open

Connection reached. Only after the block 14 has passed the in has reached the position shown in full lines, the opening 21 is again in communication with the atmosphere brought, whereby the bar can be moved under the influence of the bolt pressure, so that the measuring chambers be filled again. Since the beam 17 is held in its ejection position until the block has reached its filling position again, the pieces of food are prevented from being damaged or to disintegrate into individual lines.

If after a number of strokes of the block 14 of the piston 10 advanced by the cylinder 12 one Has reached the end division in which it is the outlet opening 13 of the channel 3 approaches, it is moved back to its starting position, in which 3 division the slide 4 is opened and a new amount of food pieces falls into the channel.

The device shown in Figure 3 differs from the device of Fig. 1 in that the partition walls between the measuring chambers are each connected in one piece with a knife 23 which extends beyond the block 14, these knives in slots 24 of the Housing of the device are performed. The cutting edges 23 of each knife 23 run obliquely with respect to the longitudinal axis of the channel 3, these cutting edges being retracted into a position outside the circumference of the channel when the block 14 assumes the position shown in full lines. When the block 14 is moved downward, the cutting edges on the ··

Make a number of "incisions" at the end of the latch in the channel 3i which incisions are aligned with respect to the partitions 1S when the block is back has reached its filling position. During the subsequent filling process of the measuring chambers 19 cause the partitions 16 in this way cause even less damage to the pieces of food.

In the device shown in Figure 4 is close to Outlet opening 13 of the channel 3 a number of fixed knives

26 arranged, the planes of these knives lying in the planes of the partition walls 18 and their cutting edges

27 in an oblique direction over the entire height of the Canal extend. Due to the relative movement between the bolt in the channel 3 and the knives 26 during the When the measuring chambers are filled, incisions are made in the bolt before it enters the measuring chambers achieved in order to reduce the damage to the food by the partitions 16 to a minimum.

The device shown in Figure 5 differs of the device shown in Figures 1 to 4 in that the block 28 containing the measuring chambers is pivotable about a fixed pivot axis 29. The block 28 is designed as a segment of a circle, its cylindrical surface constantly with a corresponding cylindrical surface of the body of the Device is in contact. In addition, the feed hopper contains a stirring device 30, which the Filling the channel 3 with pieces of food under the Hold her own weight if that benefits
