[0002] Cold chain fast food is widely available in airplanes, high-speed trains, convenience stores and other places. When eating, you only need to heat up the cold chain fast food, which is very convenient. In order to ensure the safety of food, it is necessary to test food raw materials for indicators such as bacteria, microorganisms, and metal content. Many food raw materials need to be stored frozen and need to be thawed before testing. Common thawing methods include natural thawing, water bath thawing, microwave thawing, etc.

DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

The thawing box body 13, the box body upper cover 14 and the side inclined plate box 15 are fixedly connected, and the upper flip cover 16 hinged on one side of the box body upper cover 14 can be flipped open. The heating elbow 133 is arranged inside the thawing box body 13, and water is arranged in the thawing box body 13. The heating elbow 133 heats the water at a constant temperature to keep the temperature in the water tank between zero and four degrees. Slow thawing at low temperature can maintain the quality and flavor of the frozen product and prevent bacteria from growing. After the water in the thawing box body 13 is heated by the heating elbow 133, it flows into the circulating water tank 21 through the water outlet mechanism 23 for storage, and the water delivery mechanism 22 then introduces the warm water into the thawing box body 13. Water circulation is achieved in the freezing box 13, and the flow rate of the thawing water in the thawing box 13 is increased, so that the cooling water that quickly contacts the frozen products can be replaced, thereby increasing the thawing efficiency. The frozen products are evenly placed on the sliding frame mechanism 43, and the cylinder fixing frame 31 fixes two sets of driving cylinder mechanisms 32. The two sets of driving cylinder mechanisms 32 can drive the sliding adjustment mechanism 44 to move back and forth in a small range, and shake the frozen products on the sliding frame mechanism 43 to make them fully contact with the thawing water and thaw for a period of time. After a period of time, the driving cylinder mechanism 32 can drive the sliding adjustment mechanism 44 to move to one side of the side inclined plate box 15. The two sides of the sliding adjustment mechanism 44 are slidingly arranged in the front slide rail 41 and the rear slide rail 42. The setting of this structure enables the sliding frame mechanism 43 to move obliquely to one side of the side inclined plate box 15.At the same time, the upper end of the sliding adjustment mechanism 44 contacts the upper flip cover 16 and flips and lifts the upper flip cover 16, and the frozen products on the sliding rack mechanism 43 are also moved to a position where they can be taken, so that the frozen products on the sliding rack mechanism 43 can be thawed and drained. The drained water returns to the thawing box 13 along the bottom of the side bellows 151, and as the upper flip cover 16 is opened, the fan mechanism 152 is also exposed. The two sets of fan mechanisms 152 can blow air to the frozen products on the sliding rack mechanism 43, so that the air circulation speed around the frozen products is accelerated, and the thawing and draining can be completed faster.

[0031] In order to solve the technical problem that the thawing device for food testing needs to thaw quickly while maintaining the quality of frozen products, such as Figure 2-Figure 7 As shown, the following preferred technical solutions are provided:

[0032] The thawing box mechanism 1 also includes support columns 12 fixedly arranged at the four corners of the lower end of the thawing box body 13, a fixed bottom plate 11 connected to the lower end of the support columns 12, the inner side of the bottom of the thawing box body 13 is arranged as an inclined water supply bottom 131, and a heating interface 132 for connecting a heating elbow 133 is opened on one side of the thawing box body 13. A thermostat 134 is connected to one side of the thawing box body 13. The fixed bottom plate 11 and the support columns 12 play a fixed supporting role for the thawing box body 13. The setting of the inclined water supply bottom 131 allows the thawing water to be discharged or circulated from the water outlet mechanism 23. The heating interface 132 has a built-in heating elbow 133 to heat the water at a constant temperature. The thermostat 134 controls the temperature of the heating elbow 133 and measures and displays the real-time water temperature in the thawing box body 13.

The mesh plate 1522 plays a role in fixing and dustproofing the fan blade 1523. The fan blade 1523 rotates under the drive of the driving motor 1521, thereby accelerating the air flow speed around the frozen product.

[0034] The upper flip cover 16 includes a hinge 161 connected to one side of the box upper cover 14, and a sealed flip cover 162 arranged on one side of the hinge 161. The setting of the hinge 161 allows the sealed flip cover 162 to be rotatable and open. When the upper flip cover 16 is closed, the two sides of the sealed flip cover 162 will surround the two sides of the side inclined box 15, so that the inner wall of the thawing box 13 forms a closed space, which is convenient for the sliding frame mechanism 43 to shake back and forth slightly in the thawing box 13 for thawing.

[0035] A water delivery pump 221 is provided at the lower end of the water delivery mechanism 22, and a vertical water delivery pipe 222 is provided at the upper end of the water delivery mechanism 22. The vertical water delivery pipe 222 is inserted into the thawing box 13.

The vertical water delivery pipe 222 inputs the stored water to contact the heating elbow 133. The water in the thawing box 13 can be discharged into the circulating water tank 21 through the water outlet mechanism 23 to achieve constant temperature circulation.

When the water outlet valve 2331 is closed, the water in the rectangular water outlet pipe 231 is input into the circulating water tank 21 through the L-shaped circulation delivery pipe 232 to realize water circulation. When the water outlet valve 2331 is opened, the water in the thawing box 13 is directly discharged through the heating bend 133.

The inclination amplitude of the triangular slider 323 is equal to the inclination amplitude of the front slide rail 41 and the rear slide rail 42. The telescopic cylinder 321 drives the front limit block 322 to extend and retract forward and backward. The front limit block 322 is arranged at the front end of the sliding adjustment mechanism 44 to achieve front end resistance of the sliding adjustment mechanism 44. The triangular slider 323 enables the sliding adjustment mechanism 44 to drive the sliding frame mechanism 43 to move obliquely upward along its upper end. The horizontal slider 324 plays a lateral protective role for the triangular slider 323 to prevent the sliding adjustment mechanism 44 from moving beyond the range of the triangular slider 323.

[0039] The sliding frame mechanism 43 includes a sliding grid frame 431 fixedly connected to the lower end of the sliding adjustment mechanism 44. The sliding grid frame 431 is configured as a mesh structure so that the frozen product can be fully in contact with water when thawing, and it is also convenient to drain the frozen product after thawing.
