Description

TECHNICAL FIELD

[0001] The application relates to the technical field of food thawing devices, in particular to a fluid low-temperature rapid thawing device. BACKGROUND

[0002] Rapid thawing of frozen meat can ensure thawing speed while avoiding the destruction of nutritional components and taste and the rapid reproduction of microorganisms during the thawing process of frozen meat. Common thawing methods for frozen meat include microwave oven thawing, natural thawing, water soaking and the like. Natural thawing leads to loss of nutritional components due to long-time contact with air. Water soaking is long in time and easy to breed bacteria, thereby affecting taste. Microwave ovens and other rapid thawing devices thaw frozen meat by rapidly increasing the surface temperature of the frozen meat, but due to the large temperature difference between the inside and outside, the nutritional loss and quality destruction are serious.

[0003] In summary, how to rapidly thaw food without destroying the nutritional components and taste of the food and avoiding the rapid reproduction of microorganisms is becoming a rigid requirement for rapid thawing in today's society. Therefore, it is necessary to develop a fluid low-temperature rapid thawing device to solve the above technical problems. SUMMARY

[0004] The technical problem to be solved by the application is to provide a fluid low-temperature rapid thawing device to solve the technical problem of how to avoid the destruction of the nutritional components and taste of food due to the rapid reproduction of microorganisms, small heat exchange area and slow thawing speed during the thawing process of food, and to realize low-temperature rapid thawing of frozen meat.

[0005] To solve the first technical problem, the technical solution of the application is:

[0006] A fluid low-temperature rapid thawing device, comprising a shell, the shell comprising an upper cover plate and a lower cover plate, a thawing cavity being arranged between the upper cover plate and the lower cover plate, an opening being arranged on the front side of the thawing cavity, a liquid flow channel being arranged in the interiors of the upper cover plate and the lower cover plate and being communicated, a liquid injection hole being arranged on the upper cover plate at one end of the liquid flow channel, and a liquid outlet hole being arranged on the lower cover plate at the other end of the liquid flow channel; a gas extraction hole being arranged on the shell at one side of the thawing cavity, and a sealing structure being arranged between the upper cover plate and the lower cover plate and inside the opening.

[0007] Further, a fluid pump is further arranged, the liquid outlet of the fluid pump is connected to the liquid injection hole, and the liquid inlet of the fluid pump is connected to the liquid outlet hole.

[0008] Further, the shell is made of aluminum plastic film, copper-clad film or silica gel film material.

[0009] Further, the shell has a double-layer structure, and the liquid flow channel is arranged between the inner layer and the outer layer of the shell.

[0010] Further, the liquid flow channel is arranged in an S shape inside the shell body.

[0011] Further, the sealing structure comprises sealing protrusions and sealing grooves which are engaged with each other, and the sealing structure is provided with two or more than two sealing protrusions and sealing grooves which are arranged alternately inside and outside the sealing protrusions and sealing grooves on the inner side of the upper cover plate.

[0012] The technical effects achieved by the above technical scheme are as follows.

[0013] The fluid low-temperature rapid thawing device provided by the application realizes rapid thawing of frozen meat based on fluid heat dissipation principle. Compared with the existing thawing scheme, the fluid low-temperature rapid thawing device has a large heat exchange area, a low thawing temperature, and a fast thawing speed, and can avoid the frozen meat from being oxidized due to excessive contact with air, thereby ensuring the taste of the frozen food and preventing rapid growth of microorganisms while thawing the frozen food rapidly.

[0014] Since the fluid pump is further included, the liquid inlet of the fluid pump is connected to the liquid injection hole, and the liquid outlet of the fluid pump is connected to the liquid outlet hole, the fluid pump injects liquid into the liquid flow channel through the liquid injection hole, and the fluid flows out through the liquid outlet hole, and the fluid continuously circulates to exchange heat, so that the frozen food is rapidly heat dissipated.

[0015] Since the shell is made of aluminum plastic film, copper-clad film or silica gel film material, the flexible shell can tightly wrap the frozen food, thereby improving the thawing efficiency.

[0016] Since the liquid flow channel is arranged in an S shape inside the shell body, the thawing cavity and the liquid flow channel can be in full contact, the heat exchange area is increased, and the thawing speed is improved.

[0017] Since the sealing structure comprises sealing protrusions and sealing grooves which are engaged with each other, the sealing structure is provided with two or more than two sealing protrusions and sealing grooves, and the sealing protrusions and sealing grooves on the inner side of the upper cover plate are arranged alternately inside and outside, so that the sealing effect can be ensured and air leakage can be prevented.
