[0021] Among them, the outer walls of the first tank body 3, the second tank body 4 and the condenser 1 are wrapped with an insulation layer; the tank body and the condenser 1 are insulated to reduce the temperature rise rate of the cooling material, facilitate rapid cooling, and extend the storage time. Example 2

[0022] like Figure 1 As shown, this embodiment is obtained by adding a controller, a display and other technical features on the basis of the embodiment one. The remaining technical features are the same as those of the embodiment one, and the similarities are not repeated here. Among them, the difference between this embodiment and the embodiment one is that: the first valve 5, the second valve 6, the third valve 7, the fourth valve 8, the fifth valve 9, the sixth valve 10, the cooling valve 11, and the feeding valve 12 are electric or pneumatic valves, and are electrically connected to the controller together with the temperature sensor 13 and the liquid level meter 14, and the controller is connected to the display.

[0023] In this embodiment, automatic control is achieved by electrically connecting each valve, temperature sensor 13 and liquid level meter 14 to the controller, reducing human resource costs, and displaying the temperature and liquid level on a display to facilitate observation by personnel.

[0024] The usage process of the technical solution formed by the above embodiments is as follows: the material is input into the first tank body 3 through the fifth valve 9, and after the liquid level reaches the set value, the fifth valve 9 is closed, and the first valve 5, the cooling valve 11 and the third valve 7 are opened to form a loop, and the pump 2 is operated to cool the material in the first tank body 3. After the temperature reaches the set value, the pump 2 stops working, and the first valve 5 and the third valve 7 are closed; the material is input into the second tank body 4 through the sixth valve 10, and after the liquid level reaches the set value, the sixth valve 10 is closed, and the second valve 6, the cooling valve 11 and the fourth valve 8 are opened to form a loop, and the pump 2 is operated to cool the material in the second tank body 4. After the temperature reaches the set value, the pump 2 stops working, and the second valve 6 and the fourth valve 8 are closed; when the refrigerated material is transported to the production area, the cooling valve 11 is closed, the first or second valve 6 is opened, the feeding valve 12 is opened, and the pump 2 works to discharge the material after cooling.

[0025] When the material in the first tank body 3 is cooled and the cooled material in the second tank body 4 needs to be discharged, the pump 2 stops working, the first valve 5, the third valve 7 and the cooling valve 11 are closed, the second valve 6 and the discharge valve are opened, and the pump 2 works to discharge the cooled material in the second tank body 4. After the discharge is completed, the pump 2 stops working, the second valve 6 and the discharge valve are closed, the first valve 5, the third valve 7 and the cooling valve 11 are opened, and the pump 2 works to continue cooling the material in the first tank body 3. When the material in the second tank body 4 is cooled and the cooled material in the first tank body 3 needs to be discharged, the process is the same as the above process and will not be repeated again.
