[0054] In the above embodiment, the branch pipeline on the circulation loop formed by the cooling subsystem 1 and the branch pipeline on the circulation loop formed by the heating subsystem 2 are connected to the heat transfer medium inlet end of the freeze-thaw box 3 through which the heat transfer medium enters the freeze-thaw box 3, and the heat transfer medium outlet end of the freeze-thaw box 3 is connected to the temperature control subsystem.

[0055] Specifically, the temperature regulating subsystem 4 is used to evenly mix the heat transfer medium outputted by the freezing subsystem 1 , the heating subsystem 2 and the freeze-thaw box 3 .

[0056] The temperature control subsystem 4 includes the expansion barrel 41 connected to the freezing subsystem 1, the heating subsystem 2 and the freeze-thaw box 3. The expansion barrel 41 has a moisture absorption filter 42 and a mixing device 43. The mixing device 43 is used to achieve uniform mixing of heat-conducting media of various temperatures and to reduce the pressure of the heat-conducting media.

[0060] In the above embodiment, the control subsystem 5 is used to implement automatic program control of various components of the system.

[0061] Specifically, for the refrigeration subsystem 1, the control subsystem 5 controls the first compressor to operate at the limit, always in the maximum cooling capacity state, and controls the temperature of the heat transfer medium according to the three first temperature probes 17, so that it is in a low temperature state of -90°C; similarly, for the heating subsystem 2, the control subsystem 5 controls the second electric heater 26 in the heating subsystem 2 to operate at full power, and controls the temperature of the heat transfer medium according to the three second temperature probes 27, so that it is in a high temperature state of +50°C.

[0064] Specifically, the pipeline configurations of the heat transfer medium inlet and outlet of each freeze-thaw box 3 are consistent, so that each freeze-thaw box can be independently controlled, and different products can be frozen or thawed at the same time.

[0075] Specifically, when the product needs to be thawed, the thawing temperature TT1 is set, and the control subsystem 5 adjusts the opening of the first proportional valve 6 and the second proportional valve 7 on the freezing subsystem and the opening of the first proportional regulating valve and the second proportional valve 7 on the heating subsystem according to the temperature TT2 of the heat transfer medium in the heating subsystem 2 and the temperature TT3 of the heat transfer medium in the freezing subsystem 1, so as to achieve the uniform mixing of the heat transfer medium TT1. The reduction value of the opening of the first proportional regulating valve 6 on the freezing subsystem 1 is the same as the sum of the openings of the second proportional regulating valves 7 on all its branch lines; similarly, the reduction value of the opening of the first proportional regulating valve 6 on the heating subsystem 2 is the same as the sum of the openings of the second proportional regulating valves on all its branch lines.

[0076] S5. After thawing is completed, close the proportional regulating valve on the branch pipeline, disconnect the quick connector and the temperature probe in the freeze-thaw box, and transfer the product to the application site together with the freeze-thaw box.
