Description

The invention relates to the processing of food products, in particular, to devices for forming semi-finished products (for example, meat, fish, potato and other meatballs, meatballs, etc.) from pasty food products.

A device for forming semi-finished products from pasty products can also be used on automatic filling machines as a dosing-forming device.

A device for forming semi-finished products from pasty food products is known, comprising a receiving hopper for the product, a forming mechanism with molding openings and an ejector of the formed semi-finished products til.

A disadvantage of the known device is that the pasty products stick to the parts of the ejector.

It is also known a device for forming semi-finished products from pasty products, comprising a receiving hopper for the product, forming fur, anism with molding holes, an ejector of the formed semi-finished products, made in the form of pistons and an open water bath t23.

In the known device, to avoid sticking the mass of the product to the ejector pistons, the working parts of the latter cyclically with the operation of the device are immersed in an open water bath and moistened with it.

However, the known device is characterized by the fact that the water in the bath during the operation of the device is consumed and it is necessary to monitor its level, to add periodic intervals, which complicates the maintenance of the device; the ejector pistons moistened with water moisten the surface of the semi-finished products, which in some cases is undesirable due to technological and qualitative considerations of the production of semi-finished products; with increasing device performance, i.e. with an increase in the number of its working cycles in minutes, the water in an open bath, due to inertial forces, is drained, which prevents the normal operation of the device, the ejector performs twice as many working strokes

ejection of semi-finished products from the molding holes and immersion into the bath to wet their working surfaces than the other moving parts of the device, as a result, with its high-speed operation mode, taking into account that the ejection process occurs abruptly, an excessive noise and vibration of the device appear.

The closest in technical essence and the achieved result is a device containing a product bunker, a forming mechanism and a bar with fallen pistons connected to a compressed air system for ejection of semi-finished products S.Z.

However, the known device is characterized by the fact that when a portion of compressed air is applied to the semi-fabricated at the time of their separation from the pistons, the semi-finished products are separated at the same time from the entire surface in contact with the piston. As a result, they are either scattered or interrogated on the side, i.e. do not occupy the same position, which makes it difficult to feed them to the packaging; in addition, when scattering and tilting semi-finished products, they deform Q, especially thin semi-finished products, 10-20 mm thick, as well as from some products, such as potatoes

The purpose of the invention is to increase the reliability of the device by

5 elimination of deformation and scattering of semi-finished products when they are issued.

The goal is achieved by the fact that in a device for molding semi-finished products from pasty products, containing a product bin, a mechanism and a bar with cannon pistons connected to a compressed air system, a piston with a groove on the working face surface is formed in each piston, forming with the end surface of the piston ring | slot for the passage of compressed air.

FIG. 1 is schematically depicted.

j A device for forming semi-finished products from pasty products contains a product bin 1 and a flat tank 2 with hollow pistons 3 connected to a compressed air system to eject semi-finished products.

The forming mechanism has a pressure chamber 4 with outlet openings 5, a movable plate 6 in which the molding openings 7 are made, a pressure means (for example, pores 8 for feeding the product from the receiving hopper 1 into the pressure chamber 4) creating pressure in it filling the molding openings with the product 7. In the pressure chamber 4, the overflow valve 9 is mounted to regulate the pressure in it by removing the surplus product back into the receiving hopper 1. Plank 2 with hollow pistons 3

5 mounted on drive rods 10

and 11. The shape and number of the pistons 3 correspond to the molding openings 7. Inside the hollow pistons 3 concentric with their inner surface is mounted an insert 12. A recess 13 is made on the working end surface of the insert 12, designed to reduce the area of contact between the insert 12 and the semi-finished products when they are ejected i.e. to reduce the total adhesion force of semi-finished products to it.

The liner 12 is made smaller in diameter (diameter, than the inner diameter of the hollow pistons 3 to form an annular gap 14, for the passage of compressed air acting on semi-finished products during their separation from the pistons 3.

The annular gap 14 is intended to direct the force of the ejected air to the semi-finished products directly in the vicinity of their attachment to the working end surfaces of the piston 3 and the liner 12, i.e. for reliable, simultaneous tearing of semifinished products from the entire touching surface of the pistons without subsequent scattering and deformation. when issued,.

For supplying compressed air to the annular gap 14 in the plate 2 there is a groove 15 and a nozzle 16, and in the insert 12 there is a longitudinal hole 17 and radial holes 18.

The kinematic implementation of the reciprocating motion of the forcing piston 8, the movable plate b and the piston strip 3 from a common drive is conventionally not shown.

The device works as follows.

The injection piston 8, moving from the leftmost position to the rightmost position, takes the corresponding amount of product weight from the hopper 1 and pushes it into the pressure chamber 4. At this time, the movable plate 6 moves from the rightmost position to the molding holes 7 with outlet openings 5 of the pressure chamber 4. Continuing on, the injection piston 8 closes the pressure chamber 4 and creates pressure therein, under which the molding openings 7 are filled with product through the openings 5.

Then, the movable plate 6 with the holes 7 filled with the product moves to the extreme right position, and the 8 - m delivery piston to the extreme left position and stops. The bar 2 is lowered, and the pistons 3 fixed on it pass through the molding openings 7 and push the semi-finished products out of them. At the moment when the pistons 3 reach the lowest position, through the pipe 16, the groove 15, the longitudinal hole 17 and the radial holes 18 into the annular slot 14 of the pistons 3, a portion of compressed air is fed, which presses on the semi-finished products directly near the point of their attachment to the working face the surfaces of the pistons 3 and the liners 12, whereby the semi-finished products are detached simultaneously from the entire working face, the surfaces of the pistons 3 and the liners 12 without their subsequent spreading and deformation.

Then the rod 2 with the pistons 3 rises to the extreme upper position, i.e. the pistons 3 exit the molding holes 7.

 In the future, the cycle of operation of the device is repeated.

The proposed device improves the reliability of the molding of semi-finished products from pasty food products, and also makes it possible to use it on filling and packaging machines as a dosage: vacuum-forming device, due to the exclusion of scattering of semi-finished products during their issuance.
