る。In the case of a winter season where the outside air temperature is low,
After the feed fed into the sterilizer 18 is preheated via hot air by a heater unit (heated air circulation) 50, sterilization is performed by the same operation procedure as described above. More specifically, the heater unit (heated air circulation) 50 is a known one, and has an erofin tube 51 (shown diagrammatically) in which a fin is spirally wound outside the pipe. The heating source is steam, and steam of 3 to 5 kg / cm 2 is sent from the direction of the arrow, and the circulation ducts 52 and 53 and the main body 19 are sent.
When the retained air in the inside is flowed in a direction perpendicular to the erofin tube 51, the air becomes hot air when passing through the erofin tube 51, and this hot air is circulated duct 52, an airtight valve 54, a hot air inlet 21, the main body 19, The feed in the main body 19 is pre-heated by being circulated about 10 to 20 ° C. higher than the outside air temperature by circulating in the route of the outlet 22, the airtight valve 55, the circulation duct 53, and the heater unit (heated air circulation) 50, Next, the airtight valves 54 and 55 are closed, the main body 19 is hermetically closed, and the operation is performed in the same procedure as described above to perform the sterilization process. When it is necessary to return the product temperature raised by about 10 to 20 ° C. higher than the outside air temperature by the preheating, the introduction of steam is stopped, air is introduced through the intake valve 56, and It has been returned to the original temperature. In addition, heater unit (heating air circulation) 50, circulation duct 5
2, 53 and the like have a structure integrated with the sterilizer 18.

る。By the way, depending on the feed, physical sterilization by heating may be performed instead of chemical sterilization by the above-mentioned chemicals. In this case, the feed fed into the main body 19 is heated to about 60 to 70 ° C. by the heater unit (heated air circulation) 50 to perform a preheating treatment, and then, the superheated steam from the boiler 45 is discharged to the steam header. 44, the branch pipe 40, the airtight valve 43 for superheated steam, the common supply pipe 37, and the airtight valve 38 are supplied and sprayed from the jet port 23. Under the spray of the superheated steam, the feed is stirred for a predetermined time, Body 19
The inside is evacuated to about 20 Torr by evacuation by driving the vacuum pump 31 of the vacuum pump unit 30 to reduce the pressure, and the mixture is stirred under the reduced pressure. Then, the superheated steam is satisfactorily diffused over the entire surface of the feed by the depressurizing action and is stirred. Next, when the rotation of the stirring blade 29 is stopped, the airtight valve 36 for bypass is opened, and the inside of the main body 19 is returned to the atmospheric pressure, the superheated steam is reduced by the instantaneous change in air pressure (pressure difference) at this time. To be sterilized. During the physical sterilization process using the superheated steam, it is natural that the liquid airtight valve 41 is closed to shut off the liquid path. Next, the feed sterilized by the superheated steam is supplied to the receiving hopper 4 as described above.
6 and sent out to the shipping tank 49 for later shipping.
