A connecting pipe 4 is also installed at the upper end of the storage box 1. A one-way valve 5 is installed inside the connecting pipe 4 to ensure that air in the connecting pipe 4 can only flow out of the storage box 1. A second pipe cap 6 is threaded onto the upper end of the connecting pipe 4 to seal it and prevent external dust from entering. When storing dairy products, the dairy products are filled into the storage box 1 through the filling pipe 2. Then, the connecting pipe 4 is connected to a vacuum pump, which removes the air from the storage box 1.

Inside the storage and transport box 1, two integrally connected heat-conducting pipes 7 are vertically installed. The upper end of each heat-conducting pipe 7 has an internal thread and an opening. A heat-insulating cover 8 is threaded onto the upper end of each heat-conducting pipe 7. The heat-insulating cover 8 has a through hole 801, and a pressure relief valve 9 is installed inside the through hole 801. This allows the air pressure inside the heat-conducting pipe 7 to be released outwards through the pressure relief valve 9. Dry ice is placed inside the heat-conducting pipe 7. During transportation, the continuous heat release of the dry ice lowers the temperature inside the storage and transport box 1, continuously creating a low-temperature environment, which facilitates the storage and preservation of dairy products during transportation.

The liquid is injected into the cooling channel 12 through the guide port 121 to circulate and cool the dairy products inside the storage and transportation box 1, forming a low-temperature storage environment. The upper and lower edges of the storage and transportation box 1 are provided with inverted L-shaped extensions 11. The outer edge of the extensions 11 extends beyond the cooling channel 12, so that the storage and transportation box 1 will not be squeezed when it is placed horizontally and rolled.
