In the above configuration, first, in the normal cooling operation, since the four-way switching valve (8) communicates as shown by the solid line, the high temperature / high pressure output from the compressor (3) by the operation of the compressor (3). Refrigerant gas passes through the four-way switching valve (8), most of which passes through the check valve (10) and enters the condenser (4).
After being depressurized and changed in the capillary tube (5), the mixture enters the cooler (7), where it removes the heat of the mix in the cylinder (1), evaporates and compresses through the four-way switching valve (8). The refrigeration cycle is returned to the machine (3). As a result, the mix in the cooling cylinder (1) hardens into a product and can be taken out from the take-out device (2).

On the other hand, the heat sterilization operation is performed by switching the four-way switching valve (8) as shown by the dotted line. In this case, the high-temperature and high-pressure refrigerant gas exiting the compressor (3) enters the cooler (7) via the four-way switching valve (8), where the cooling cylinder (1) and the mix are heated to condense and liquefy. Most of this liquid refrigerant does not pass through the capillary tube (5) but accumulates in the condenser (4) through the check valve (6), and the gas refrigerant above the condenser (4) passes through the expansion device (9). A reverse refrigeration cycle is returned to the compressor (3).

By the way, the temperature of the refrigerant flowing into the condenser (4) does not drop to a temperature at which the cooling water freezes, and there is no need to flow the cooling water to absorb heat. According to the embodiment of the present invention, since the discharge pressure of the compressor (3) is low at the initial stage of heating, the water saving valve (15) is in a closed state, and water is not passed through the water pipe (14). Thereafter, as the heating operation progresses, the discharge pressure gradually increases. When the pressure exceeds a set value, the water saving valve (15) is gradually opened to flow through the water pipe (14), and the water is passed through the condenser (4). Dissipates heat to lower the refrigerant temperature. Like this
In the reverse refrigeration cycle, the temperature of the refrigerant flowing into the condenser (4) does not drop to a temperature that freezes the cooling water, so that it is not necessary to flow the cooling water throughout the entire cycle, and the refrigerant temperature is reduced. The reverse refrigeration cycle can be performed only by passing water only in the latter stage of heating in order to prevent a rise in the temperature. In addition, as a pressure reducing device, a pressure adjusting valve such as an expansion valve may be used in addition to the capillary tube.

Thus, in the heat sterilization operation by the reverse refrigeration cycle, the cooling cylinder (1) and the mix surely complete the sterilization, and the end of the sterilization operation is regulated by temperature. In addition, the reverse refrigeration cycle can be used for the sterilization operation of the cooling cylinder (1) and the mix. For example, when cleaning the cooling cylinder (1) periodically and softening and collecting the product inside the cylinder (1). Can also be used.
