Description

one

A device for the injection of Ca m in the process of its salting is intended for the introduction of brine into meat with the production of sausage-ham products and can be used in the meat industry in milling enterprises.

A device for injection of meat during its salting is known, comprising a conveyor for feeding meat, a brine delivery system, a pneumatic system, an injection device comprising a manifold mounted on guide posts with the ability to move in a vertical plane, a movable bar attached to the collector. holders with needles and located in the latter, as well as a drive (1.

The disadvantage of this device is the deformation or breakage of the needles as a result of the lack of adjustment of the brine pressure, which reaches a considerable value when it comes into contact with the bone.

Due to the lack of elasticity in the fluid medium used as the working fluid, the performance of the syringe decreases, and during the contact of the needle with the bone, the brine continues to flow, which causes salinity in this place.

As a result of the fact that the movable strap of the needle bridge is pressed by means of compression springs, small pieces of meat can be squeezed (squeezed out) by the strap from the working area; in addition, the range of processed raw materials is limited.

The purpose of the invention is to increase the reliability of operation by eliminating breakages and deformation of the needles at the time of contact with the bone and improving the quality of salting.

For this reason, the collector is made with two compartments, the lower one of which is connected to the pneumatic system and the cavities of the guide holders, and the upper one - to the brine supply system, with each holder provided with an abutment and has an opening positioned so that in the initial position and at injection it is combined with the upper reservoir compartment.

In addition, at the ends of the strip, there are cylindrical holes, and the guide posts are connected to the pneumatic system and are equipped with pistons installed with the possibility of inserting them into the holes of the strip. FIG. 1 shows the described device, a general view; in fig. 2 shows section A-A in FIG. in fig. 3 is a view along arrow B in FIG. 2; in fig. 4 shows a section B-B in FIG. 2; in fig. 5 - device for injection in operation. The device has a housing 1, an oil supply conveyor 2, a brine supply system, a pneumatic system 3, an injection device, water and a control mechanism 4. The injection device comprises a manifold 5, an upper compartment 6 and a lower compartment 1. The cavity of the upper compartment 6 through Holes 8 are connected to hose 9 supplying brine from the paccoxta feed system. The cavity of the lower compartment 7 is connected with the cavities 10 of the tubular guides 11 rigidly attached to the manifold 5. The guides 11 are equipped with pistons 12, have holes 13 through which the cavities 10 communicate with the chassis cavities 14 of the movable plan 15. The lower The compartment 7 and the cavities 10 and 14 are connected via a flexible hose 16 to the pivic system 3. The guides 11 are connected to the pneumatic power rods 17. The movable bar 15 has sealing sleeves (18, in the holes of which the ends of the injection needles 19 with holes The injection needle 19 is reinforced in The holder 20. A piston 21 is mounted at the lower end of the holder, and an abutment 22 is mounted at the upper end. The holders 20 in the upper part have radial holes 23 communicating with the cavity of the upper compartment 6, and the piston 21 is placed in guide -24 communicating with the cavity lower compartment 7. The syringe drive consists of a pneumatic cylinder 25 whose rod is connected to a ratchet mechanism 26. A sprocket is fixed on the same shaft with the ratchet mechanism 26, driving a conveyor chain 2. The control mechanism 4 is connected to a cam system 27. Brine delivery system composed from tank 28 and cylinder 29 with piston 30 connected through hose 9 to upper manifold cavity 5. Works jiiirTpH. in the following way. On the conveyor 2 on the right side stack lumpy m with. The control mechanism 4 is activated to cycle the syringe. Using the cam system 27, a signal is applied to the pneumatic cylinder 25, which through the ratchet wheel 26 moves the conveyor chain to the desired value. At the same time, the cam 27 of the system 27 is given a signal to turn on the pneumatic system 3 and the brine delivery system, from the pneumatic system 3 air is supplied to the pneumatic cylinder 17 and through the hose 16 and the cavity 10 of the guides II - to the lower compartment of the collector 5. At the end of the movement of the conveyor 2 by one cam jaw system 27 stops the conveyor and determines the time it takes for the meat to be extruded with brine. As soon as the conveyor is stopped, the rod of the pneumatic cylinder 17 lowers the injection device and brings it to the mouse. At the same time, an adjustable dose of brine from the tank 28 is supplied to the cavity of the cylinder 29 and the piston 30 is pumped through the hose 9 into the upper cavity .6 of the manifold 5. The operation of the injection device is performed as follows. As soon as the fixture approaches the mozyr, the movable bar 15 presses the lumpy mois. The amount of pressure is regulated by using compressed air supplied from the pneumatic system 3 into the cavity 14 of the bar 15. The guides 11 of the device continue to move downward, overcoming the resistance of the compressed air by the pistons 12. With this, the needles 19 exit the sealing sleeves 18, insert the tempered grains into the grains and inject the brine into it. If the tip of the injection needle meets the bone, the holder 20, overcoming the compressed air resistance by the piston 21, begins to move upwards. The holder hole 23 extends from the upper cavity of the manifold 5, and the brine feed to the needle is stopped. This eliminates the re-salting of meat in the zone of its joining with the bone. At the end of the injection period, the injection device moves upward and under the action of compressed air all its elements return to their original position. The raw material processed on the syringe is discharged from the co-winery 2 on the left side into special carts. The invention will improve the quality of the product being manufactured and labor productivity, as well as increase the reliability and durability of the device. Claim 1.
