The purpose of the present invention is to solve the above-mentioned conventional problems.To achieve the above-mentioned purpose, the present invention provides a sterilization tank at the front stage, a cleaning means at the rear stage, and a heat pump heating mechanism in the sterilization tank. The cleaning means is equipped with a cooling mechanism for the heat pump.

[Effect]

The present invention is based on the above-mentioned structure, and the cleaning means uses a cooling mechanism of a heat pump to extract energy for cooling, and the sterilizing tank is heated by supplying the energy to a heating mechanism.

[Effect of idea]

Since the present invention has the above-mentioned structure and function, the energy taken by the cooling by the cleaning means can be used for heating the sterilization tank, and the energy efficiency is greatly improved.

A water-cooled type may also be used.

In the above configuration, the sterilizing tank 1 is filled with water containing a sterilizing agent such as sodium hypozinc oxide or acetic acid, heated to about 50 to 80°C, and air is blown into the water from the air blowing pipe 11. Vegetables or processed vegetable products such as pickles are fed into the sterilization tank 1 from the inlet 12 as the processed material T. During such treatment, the water in the tank flows from the inlet 12 of the sterilizing tank 1 to the outlet 13 by the pump 15, and then returns to the inlet 12 of the sterilizing tank 1 from the reflux path 14. During this time, the water flows through the heating device 17. is heated to the above temperature range. The material to be treated T comes into contact with water containing the disinfectant in the tank and is sterilized while being carried by the water flow to the outlet section 13 where it is taken out by the take-out conveyor 16. Then, on the conveyor 16, cold water is removed from the cleaning tank 2 by the shower 3 via the water supply path 32 by the pump 31, and the disinfectant adhering to the object T to be treated is washed off. Thereafter, the object to be treated T is introduced from the conveyor 16 into the inlet portion 22 of the cleaning tank 2 . In the cleaning tank 2, the workpiece T is cleaned while blowing air into the water in the cleaning tank 2 from an air blowing pipe 21. The water in the cleaning tank 2 flows from the inlet part 22 of the cleaning tank 2 to the outlet part 23 by the pump 25, and further flows through the reflux path 24.
The water flows back to the inlet section 22 of the cleaning tank 2, and during this period, the water is cooled by the cooling device 27. The object T from which the sterilizer has been completely removed is carried by the water flow to the outlet 23 of the washing tank 2 and taken out from the take-out conveyor 26, where the water is removed by the shower 4 and the object T is completely washed. Ru.

Closed circuit 51 in heat pump system HP
The circulating medium is compressed and liquefied by the compressor 54, and the heating mechanism 52 of the heating device 17 radiates heat to heat the heating device 17. The radiated medium is stored in the receiver 56 and the valve 61 is heated. The water from the cleaning tank 2 is cooled by being dehumidified by the dryer 55 and vaporized by the cooling mechanism 53 of the cooling device 27 . The suction pressure of the thus vaporized medium is adjusted to a predetermined value by the suction pressure regulating valve 58, and the medium is circulated to the compressor 54 again. In the heat pump system HP, an extra amount of heat is added to the medium based on the mechanical work of the compressor 54, and the temperature of the medium in the system gradually rises, and the pressure also rises. When a predetermined pressure rise is reached, the condensing pressure regulating valve 65 opens, the medium flows through the auxiliary condenser 63, and heat balance is achieved by radiating heat to the surroundings. Furthermore, if heat dissipation conditions are poor, such as high ambient temperature or poor ventilation,
This is detected by the thermostat 66 and the fan 64 is operated to air-cool the medium passing through the auxiliary condenser 63 to achieve heat balance.

Other than this embodiment, the cleaning means after the sterilization tank may be only a shower or only a cleaning tank.
