The invention relates to heat treatment (sterilization, pasteurization of food products, found in sealed cans and can be used in the fish, meat, vegetable and other industries engaged in processing and preserving food in metal cans.

The purpose of the invention is to increase the operational reliability and expansion of the sizes of the processed cans at the expense of providing them with air-lift transportation through the apparatus.

Figure 1 shows a schematic representation of the apparatus, the frontal section; figure 2 is the same cross section; FIG. 3 is a side section of the channel with a discharge device.

A continuous heat treatment apparatus for products in cans comprises a vertical body 1 with a tapering lower part 2, circulating 3 and separating 4 partitions forming the ascending 5 and descending 6 channels, the bottom of the body 7, which is corrugated so that each side The corrugation forms the bottom of one of the channels, with the sections 8 of the bottom 7 located below the ascending channels perforated, as well as inclined perforated guides 9, a pipe for entering Yu and exit 11 steam, steam capacity 12, loading 13 and 14 gruzochnoe device. The baffles 3 and 4 are fixed on the sides of the walls of the casing 1, while the upper ends of these baffles are located below the level of the liquid filling the apparatus by an amount not less than the largest size of the jar to be processed. Circulating partitions 3 in the lower part form a gap with the bottom 7.

The size of this gap should be equal to the largest of the size of the jar to be processed. The angle of inclination of the solid portion of the bottom 7 is chosen so as to ensure the guaranteed movement of the can toward the perforated portion 8, the angle of which can be different and selected from the conditions of the smallest flow resistances.

The circulation partitions 3 in the upper part have inclined guides 9, which are punched perforated, the seat was able to return to the descending channel 6. The loading device 13 is located outside the apparatus. The device includes only a pipe through which the bank from the boot device enters the device. In this case, the movement of the canister is carried out by force of gravity, since the nozzle is located at a certain angle to the horizontal. The outlet of the nozzle is located above the channel 6 at the level of the surface of the liquid, which facilitates the sliding of the can from the nozzle into the channel.

Razgru: zochny device 14 is also located outside the unit. The entrance to the unloading device is located at the bottom of the iryca core, flush with the inclined solid section of the bottom 7. The side walls of the housing in the channel with the unloading device are inclined, shaped 5

connecting to the center of the inlet nipple

boot device (Fig. H).

Alparat works as follows.

Through any of the pipes 10 or 1 1 (or a pipe specially welded to the body for filling the apparatus) the apparatus is filled with a heat-transfer fluid (for example, water). Then, through pipe 10, steam is supplied to steam vessel 12. Next, steam passes through openings in the perforated portion of bottom 7 and bubbles in channels 5 as puzzles, causing an upward movement of the vapor-liquid mixture in them. Upon reaching the required temperature and pressure in the apparatus, banks intended for heat treatment are fed through the loading device 13. Once in the canal, the banks move in the downstream with the fluid gradually warming up. Reaching the bottom 7, the banks roll down the inclined solid bottom section and fall under the upward flow of the vapor-liquid mixture, which picks them up and moves them to the upper part of the channel, where the vapor is separated from the liquid, and the bank is thrown into the next channel with the downward flow. To ensure that the can is moved to the next channel, in the upper part of the circulation partition, there are perforated inclined guides 9

Thus, the can passes through a series of channels, the length and number of which is determined from considerations of the heat treatment time. Getting into the last canal, the can, due to its shape, drops exactly to the entrance of the unloading device and is pushed out due to the pressure in the apparatus and the force of gravity.

Thus, the movement of the can in the apparatus is due to the airlift effect of the vapor-liquid mixture, the difference in the density of the can and liquid, and also the descent of the first flow. No mechanical conveyors are required, which is 1 S6.

MO simplifies the design of the meltllotz for heat treatment (storilizatgfov, pastorichorop). On the other hand, this design allows processing banks of any sizes and does not require any alterations for this.

The effect of weight and can size on

The Q residence time can be easily controlled by the steam supply, i.e. change in steam content in the upstream. This changes the flow rate of the fluid in the channels 5 and 6.

C The use of an airlift-type apparatus makes it possible to significantly reduce the capital expenditures on its creation and installation.
