Detailed Implementation

[0019] The present invention will now be described in further detail with reference to the accompanying drawings.

[0020] Example 1 Please see Figure 1-6 As shown, this embodiment provides a temperature-controlled water-cooled defrosting device for pre-prepared food processing, including: a defrosting box 1 and a water circulation assembly. The defrosting box 1 is a hollow cavity structure with an open top and an inclined bottom. A shelf 5 is movably connected inside the defrosting box 1. Connecting rods 13 are connected to both sides of the shelf 5, and the other end of the connecting rods 13 is connected to a reciprocating lifting structure. A water outlet is provided through the lower part of one side of the defrosting box 1, and a water inlet is provided through the upper part of the other side. The water circulation assembly includes a water storage tank 2 and a circulation pump 11. The water outlet of the water storage tank 2 is connected to the water inlet of the defrosting box 1 through a second connecting pipe 10, and the water inlet of the water storage tank 2 is connected to the water outlet of the defrosting box 1 through a first connecting pipe 9. The circulation pump 11 is installed in series on the second connecting pipe 10, and a filter assembly is detachably installed inside the water storage tank 2.

[0021] The defrosting chamber 1, as the core operating cavity, adopts a hollow structure design with an open top, facilitating quick loading and unloading of pre-prepared food by staff. Its sloping bottom guides blood and impurities generated during defrosting to one side, allowing them to drain with the water flow and preventing accumulation that could affect defrosting efficiency. An internally connected shelf 5 holds the pre-prepared food to be defrosted, ensuring full contact between the food and the running water. Simultaneously, connecting rods 13 on both sides connect the shelf 5 to a reciprocating lifting structure, enabling its up-and-down reciprocating movement. The reciprocating lifting structure, connected to the connecting rods 13 on both sides of the shelf 5, moves the shelf 5 within the defrosting chamber. The internal structure undergoes periodic lifting and lowering motions to break up the stagnant layer on the surface of the pre-prepared food, ensuring that all parts of the pre-prepared food are continuously in contact with fresh running water, thus avoiding the problem of insufficient thawing in certain areas. The water circulation component includes two core components: a water storage tank 2 and a circulation pump 11. The water storage tank 2 provides storage space for the constant temperature water source, while the circulation pump 11 provides power for water circulation. The first connecting pipe 9 and the second connecting pipe 10 form a closed loop, respectively enabling the water storage tank 2 and the thawing tank 1 to connect for water inlet and outlet, ensuring that the water can circulate. The removable filter component inside the water storage tank 2 is used to intercept and filter impurities, blood, and other contaminants in the circulating water.

[0022] Example 2 Please see Figure 1-6 As shown, in this embodiment, the side wall and bottom wall of the shelf 5 are provided with several equidistant through holes 12. The four corners inside the defrosting box 1 are connected with guide rods 15. The side wall of the defrosting box 1 is provided with limiting holes 14 corresponding to the guide rods 15. The two side walls inside the shelf 5 are provided with first sliding grooves 16. The connecting rod 13 corresponds to the first sliding groove 16. The lowest point of the bottom of the defrosting box 1 is connected to a drain pipe 3. A drain valve 4 is installed in series on the drain pipe 3.

[0023] The first slide groove 16 can guide and limit the installation and movement of the connecting rod 13, ensuring that the connecting rod 13 drives the shelf 5 to rise and fall smoothly without deviation; the guide rod 15 and the limiting hole 14 can further limit the lifting trajectory of the shelf 5, preventing tilting and shaking during the lifting and lowering process; after the defrosting operation is completed, the residual blood, impurities and some water in the box can be quickly discharged by opening the drain valve 4 to avoid pollutant residue and facilitate subsequent cleaning and maintenance; the equidistant through hole design on the side wall and bottom wall of the shelf allows the constant temperature water flow to penetrate through each layer of pre-prepared food without obstruction, solving the problem of slow local defrosting caused by poor water flow in traditional shelves.

[0024] Example 3 Please see Figure 1-6As shown, in this embodiment, the reciprocating lifting structure includes a drive assembly, an eccentric wheel 8, and a connecting shaft 18. One side of the eccentric wheel 8 is connected to the drive assembly, and the other side has a second slide groove 17. One end of the connecting shaft 18 is located in the second slide groove 17, and the other end is connected to the top of the connecting rod 13. The second slide groove 17 is convex in shape, and the end of the connecting shaft 18 connected to the second slide groove 17 corresponds to this shape. The other end of the connecting shaft 18 is rotatably connected to the top of the connecting rod 13. The drive assembly includes a fixed plate 6, a drive motor 7, and a rotating shaft 19. The fixed plate 6 is connected to the side wall of the defrosting chamber 1, the drive motor 7 is connected to the surface of the fixed plate 6, one end of the rotating shaft 19 is connected to the output end of the drive motor 7, and the other end is connected to the eccentric wheel 8.

[0025] The fixing plate 6 is connected to the side wall of the defrosting box 1, providing stable installation support for the drive motor 7. The drive motor 7 is connected to the surface of the fixing plate 6. One end of the rotating shaft 19 is connected to the output end of the drive motor 7, and the other end is connected to the eccentric wheel 8, forming a power output link. One side of the eccentric wheel 8 is connected to the rotating shaft 19 of the drive assembly, and the other side has a "convex" shaped second slide groove 17. One end of the connecting shaft 18 is adapted to the "convex" shaped slide groove and embedded in the groove, and the other end is rotatably connected to the top of the connecting rod 13. The design of the "convex" shaped slide groove and the adapted connecting shaft 18 allows the drive motor 7 to drive the eccentric wheel 8 to rotate, and through the cooperation of the slide groove and the connecting shaft 18, the circular motion is converted into the reciprocating lifting motion of the connecting rod 13, thereby driving the shelf 5 to make periodic up and down lifting motion in the defrosting box 1, breaking the stagnant layer attached to the surface of the pre-prepared food, avoiding local temperature accumulation, and allowing all parts of the pre-prepared food to continuously contact the fresh constant temperature water flow, ensuring uniform defrosting.

[0026] The filter assembly includes a filter cotton layer 20 and an activated carbon layer 21, and the filter cotton layer 20 and the activated carbon layer 21 are arranged sequentially inside the water storage tank 2.

[0027] The filter cotton layer 20 can initially intercept and filter larger particulate impurities (such as pre-cooked food scraps, blood clots, etc.) in the circulating water flow, while the activated carbon layer 21 can further adsorb small impurities and odor molecules in the water flow. The dual filtration structure can more accurately and thoroughly purify the circulating water quality.

[0028] Working principle: First, constant-temperature clean water, appropriate for the type of pre-prepared dish, is injected into the water storage tank 2. Then, the pre-prepared dishes to be thawed are evenly layered on the shelf 5, avoiding stacking to ensure sufficient water contact. The circulation pump 11 is started, and constant-temperature clean water in the water storage tank 2 is slowly injected from the upper water inlet of the thawing box 1 through the second connecting pipe 10. When the water level gradually rises to the lower water outlet, the water carrying blood and impurities flows back to the water storage tank 2 through the first connecting pipe 9, forming a stable closed-loop water circulation. At the same time, the drive motor 7 of the reciprocating lifting structure is turned on. The motor drives the eccentric wheel 8 to rotate through the rotating shaft 19. With the cooperation of the "convex" shaped sliding groove and the connecting shaft 18, the circular motion is converted into the reciprocating lifting motion of the connecting rod 13, which in turn drives the shelf 5 to rise and fall smoothly along the four corner guide rods 15 of the thawing box 1. The through holes 12 of the shelf 5 allow the water to smoothly penetrate each layer of pre-prepared dishes. The dynamic lifting and rising water work together to break the stagnant layer on the surface of the pre-prepared dishes, peel off the blood and impurities, and discharge them with the water flow. After being purified by the filter cotton layer 20 and activated carbon layer 21 inside the water storage tank 2, the returned water becomes a constant temperature water source for recycling.
