(5) DEVICE FOR HEAT TREATMENT OF FOOD PRODUCTS IN BANKS

I

The invention relates to devices for the heat treatment of food products in cans and can be used in the food industry, especially when blanching fish laid in open cans.

A device for heat treating food products in cans is known, comprising an endless chain conveyor with plates and combs for placing til cans between them.

A disadvantage of the known device lies in its low productivity, due to the fact that the plates and the dies are designed so that they do not allow the conveyor chain to be fully loaded with banks.

The purpose of the invention is to increase the productivity of the device by providing a tighter arrangement of cans on the conveyor.

To achieve the goal in a device for heat treatment of food products in cans including an endless chain conveyor with plates and combs for placing cans between them, the combs are corrugated with through grooves in the valleys of the corrugations for the passage of steam and broth draining and have a 7-shaped form in cross section , and the plates are also made with through grooves and provided with latches for fixing the combs.

Figure 1 shows a device for the heat treatment of food products in cans, a general view; in fig. 2 - comb with banks mouth. On the technological circuit of the chain eipa on the fig. 3 section aa in fig. 2, fig.

20 in FIG. 2, FIG. 5, view B in FIG. 2 in FIG. 6 is a section bb in FIG.

The device consists of a loading conveyor 1, casing blan 39

shirovalel 2, discharge conveyor 3, tray, conveyor with carrier 5 D for cans consisting of endless chains 6, with sprockets 7 and 8, partitions S, dividing the body into zones of cooking and drying, air ducts 10 for feeding and suction of an air-steam mixture, bubblers 11 serving to supply steam to the blanching area, plates 12 and combs 13, pallets 1 and latches 15. The carrier 5 for the cans is formed by each pair of combs 13. having a Z-shape in cross section. Each comb 13 is installed in the slots of the plates 12, which are fixed in pairs on each link of the parallel chains 6, which allows assembling a number of cans through two steps of the chain. Plates 12 .. are provided with latches 15. The front surface of the comb 13 is made corrugated with through slots in the valleys of the corrugations. The combs 13 in the plates 12 are mounted so that the upper bent edges of the combs 13 are directed in the direction opposite to the direction of movement of the conveyor.

A device for the heat treatment of food in cans works as follows.

The fish in the cans, in the downward position from the loading conveyor 1, collides with the next approx. Comb 13. At the moment of loading, the comb 13 is in a horizontal position, parallel to the loading conveyor belt 1. The banks 5 with fish are located on the reverse side of the comb 13.

Further, as the chain 6 descends from the sprocket 8, the comb 13 takes a vertical position, becoming parallel to each other and forming the carrier where the cans 5 with fish are placed. In this case, the banks 5 from the downward position move to the position on the side. With its open part, the can 5 is supported on the front surface of the frontal comb 13. The fish in the cans 5 contacts the surface of the comb 13 only where it touched the tops of the corrugations.

In such a position, the cans 5, together with the upper branch of the conveyor, pass through the zone of boiling and fall onto an asterisk 7. Passage through this

064

the sprocket of the comb 13 remains parallel with each other. The distance between the teeth of the sprocket 7 is calculated so as to ensure 5 a constant position of the combs 13. At the same time, the cans 5, together with the carriers, move along the asterisk 7, rotate 180, gradually moving from the vertical position on the 0 side to the position upside down and again to the position on the side, in which they, together with the conveyor belt, move through the drying zone.

5 The broth formed in the cans 5 when blanching fish is drained through grooves made in the troughs of the corrugations in the comb 13. The broth is collected in the trays 1 having troughs (not shown) along which it is then removed from the device.

When passing through the drying zone, the remaining 5 banks of broth are drained and the fish is dried. five . Then the carriers, together with the banks 5 in them, again arrive at the sprocket 8. The comb 13 alternately, skirting the sprocket 8, moves from the vertical position to 0 horizontal. The cans 5 at this moment under the action of their own weight fall down on the horizontal portion of the tray f, and the next for the previous comb 13 pushes the cans 5 with fish further to the inclined portion of the tray 4, in which they move to the discharge conveyor belt 3The comb 13 is attached in the plates dr 12 as follows. It is necessary by gently pressing the fingers to bend to the sides of the flexible latches 15 to install the comb 13 in the slots of the plates 12 so that its end tabs enter. in the grooves of the plates 12, then release the latch 15.

The removal operation of the comb is similar.

In the proposed device

cans are arranged through every

two chain steps, which allows to increase the filling of the conveyor and provides an increase in the productivity of the device by 1.5 times.

The execution of the dies makes them easy to manufacture and convenient to operate. It only takes a few seconds to install and remove each comb separately.

Making the comb corrugated significantly reduces the surface of its contact with fish, which has a positive effect on the quality of canned food. Through the grooves made in the front walls of the combs, the heat carrier is evenly distributed between rows of cans, creating favorable conditions for leveling the thermal field between them. In addition, the broth is drained through the slots, which is formed in the cans during the heat treatment of the fish.

Making the combs Z-shaped provides them with sufficient strength in the loaded state, and also ensures the stable position of the cans on any part of the conveyor, preventing the possibility of their falling out of the carriers.
