First, preheating tank 1. Heating tank 3. The pre-cooling tank 4 and the cooling tank 8 are filled with water. Then, the electromagnetic switching valves 13 and 18 are opened to flow heating steam produced by a boiler device (not shown) into the heating vibrator 10 facing the preheating tank 1 and the heating vibration 11 facing the heating tank 3. Each tank 1,
Heat the water in 3. At this time, since the water temperature in the pre-cooling tank 4 is lower than the predetermined temperature (50C to 65C), the temperature control sensor 7 that detects this does not issue an activation signal for the circulation device 5, and therefore the water temperature in the pre-cooling tank 4 is initially at room temperature. Then, when the temperature of the water in the preheating tank 1 rises to within the preset temperature range (50C to 65C), the preheating tank sensor 15 detects this, and as a result,
The electromagnetic switching valve 13 is closed via the control device 14 to cut off the flow of heated steam within the heating vibrator 10 and stop the liquid temperature from rising any further.

Similarly, the temperature of the water in the heating tank 3 is set to a preset temperature (
When the temperature rises to within the range of 80C to 95C, the heating tank sensor 17 detects this, and the electromagnetic switching valve 18 is closed via the control device 14 to switch off the heating vibrator 1.
The flow of heated steam in 1 is cut off to stop the liquid temperature from rising any further.

When the liquid temperature in the preheating tank 1 and the liquid temperature in the heating tank 3 both reach a predetermined temperature, the wire mesh chain conveyor serving as the conveying device 6 is operated, and the food 2 placed on the wire mesh chain conveyor L is First, it is transported into the preheating tank 1. In the preheating tank 1, the food 2 is preheated from room temperature to 50tZ' to 65r, and the preheated food 2 is transported to the next heating tank 3. At this time, when the liquid temperature in the preheating tank 1 falls below a predetermined temperature, the preheating tank sensor 15 detects this and opens the electromagnetic switching valve 13 to allow heated steam to flow into the heating vibrator 10 as a heat source. Through heat exchange at this time, the temperature of the liquid is raised to a predetermined temperature. Thereafter, the operation of the heat source is stopped by a command from the preheating tank sensor 15, and the preheating tank 1 is restarted.
Its operation is stopped until the temperature of the liquid in the tank falls below a predetermined temperature.

The food 2, which has been preheated by being immersed in the hot water in the preheating tank 1, is transported into the heating tank 3, and is transported while being immersed in hot water that is close to boiling. This 80C
It adheres to the surface when being transported through hot water at 95C to 95C,
Or, any germs that have entered the interior will be sterilized. When the temperature of the liquid in the heating tank 6 falls below a predetermined temperature, the heating tank sensor 1

Since the water in the pre-cooling tank 4 is initially at room temperature, the food 2 is also cooled to near room temperature. However, as food 2 that has been heated and sterilized in a high temperature state is brought in, thermal energy of the food 2 is taken away and the temperature of the water rises. When the temperature of the water in the pre-cooling tank 4 reaches a predetermined temperature, the temperature adjustment sensor 7 detects this, and the circulation device 5 is thereby activated via the control device 14. As a result, the liquid heated by the food 2 that has been heat sterilized and is in a high temperature state is sucked by the hydraulic pump 22 and
The cooled liquid introduced into the preheating tank 1 through the preheating tank 1;2 and cooled to preheat the food 2 is sucked by the hydraulic pump 2B and circulated into the precooling tank 4 through the return pipe 21. . Therefore, when the liquid temperature in the pre-cooling tank 4 is higher than the predetermined temperature, the high temperature liquid is supplied into the -r heat tank 1. In this case, the liquid temperature in the pre-heating tank 1 is higher than the pre-determined temperature. Even if the temperature becomes low, there is no need to operate the heat source on the preheating tank 1 side. Therefore, the operation of the boiler device that produces heated steam can be reduced.

Next, the food 2 that has been precooled while passing through the precooling tank 4 is transported into the cooling tank 8 (-) and cooled to room temperature (5C to 20C). When the temperature rises due to the thermal energy of 2 and becomes higher than a predetermined temperature, the cooling tank sensor 27 detects this, opens the electromagnetic switching valve 28, opens the cooling pipe line 24, and supplies cooling water.
