Description

The invention relates to the field of food processing and can be used, in particular, in the production of canned fish and meat, their sterilization in a clogged form.

Known devices for the sterilization of canned goods by LAGARDE company (France) containing a horizontal autoclave, water, steam and air supply lines, a water discharge line and a controlled valve system (see EPO Patent No. 1820410 A1, IPC A23L 3/00, V.P. Babarin . "Sterilization of canned food", St. Petersburg, GIORD, 2006, p.221-224).

These devices are quite complex, the design of the autoclave provides the process of cooling the sterilized product in two stages, and the process water is drained at the end of the cycle.

The closest in technical essence and adopted for the prototype is the device for sterilization of canned food "STERIFLOW" (see V.P.Babarin. "Sterilization of canned food", St. Petersburg, GIORD, 2006, p.219-221). The disadvantage of this device, as well as the device of the LAGARDE company, is that high-quality process water, which is used to sterilize and cool products, after that does not participate in the technological process, but is drained through a drain device into the sewer or into the sea when used on floating fisheries.

The problem solved by the claimed device is to reduce the flow of quality water necessary for the operation of the sterilization device, which is especially important for floating fish factories, which have limited supply of quality water.

This problem is solved in that the device for sterilization of canned food, containing at least one autoclave connected to the supply and discharge of process water, contains a reverse water supply system including a water purification unit connected to the process water drain line, an ultraviolet disinfection unit and two storage containers, one of which is connected through check valves and pumping and pumping pumps with a purification unit and connected to the process water line, and the second inlet is connected to UV disinfection device and output - with a pump for the process water supply line.

At the same time, the cleaning unit contains a coarse filter, a grease separator equipped with a grease discharge valve, and a fine filter.

The essence of the proposed technical solution is illustrated by the drawing. The device comprises one or more autoclaves 1, a transport and loading device 2, a process water supply line 3, a water discharge line 4, a reverse water supply system 5 connected between drain and supply water lines 3, 4. The reverse water supply system includes a water treatment unit 6 and ultraviolet water disinfection unit 7, as well as storage tanks 8 and 9. The water treatment unit includes a coarse filter 10, a separator of the fat fraction 11 with a controlled valve 12 for discharging greasy waste and a fine filter and 13. The separator 11 and the fine filter 13, respectively, through a pump out pump 15, controlled valves 16, 17 are connected to a storage tank 8 connected to the supply line of process water through valve 18. The drawing also shows controlled valves 19, 20, 21, 22 , 23, 24, pump 25.

A device for sterilizing canned food is as follows. Industrial water is poured into the storage tank 8, the pump 15 is turned on and the water enters the storage tank 9, passing a fine filter 13 and an ultraviolet disinfection unit 7. A certain amount of water from the tank 9 is pumped through the valves 25 through the valves 22 and 19 into the autoclaves 1. After loading the autoclaves 1 in them using a controlled valve 23, steam is supplied from the line and canned food is sterilized for a predetermined time. To eliminate the leakage of cans with canned goods loaded into the autoclave, backpressure is created by supplying air through valve 24. After sterilization, the outlet valves 20 are opened and the pump 14 is turned on. Dirty water with fragments of the canned products (in case of can’s leakage) passes through the coarse filter 10, separator 11, pump 14, check valve 16 and enters the storage tank 8. Valves 20 are closed, pump 14 is turned off, and valves 21 and pump 15 are turned on. Water from the storage tank 8 through the non-return valve 17 and the fine filter 13 enters through the block (s) of ultraviolet disinfection of water 7 into the storage tank of clean water 9, from the storage tank 9 pure drinking water through a controlled valve 22 is pumped through the valves 25 using a pump 25 19 into autoclaves 1 for reuse. The valve 18 is used for the inlet of industrial water in order to maintain the debit of recycled water and flushing the tank, and the valve 12 for the discharge of fatty waste.

Water consumption during the operation of autoclaves is from 300 to 1000 liters per autoclave. The minimum saving of the water resource of production when using one autoclave will be at least 1,500 liters of water per shift. In the case of a production line of six autoclaves, this device will save about 9000 liters of water, which is especially sensitive for floating fish factories.
