Detailed Implementation

[0024] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0025] Refer to the diagram Figures 1-5 This utility model provides a sterilization and thawing rack for quick-frozen food production, including a thawing box 1, with a sealed box door 2 connected to the front of the thawing box 1 via a hinge.

[0026] A door lock that engages with the defrosting box 1 can be installed on the sealed box door 2. In addition, to ensure the sealing of the sealed box door 2 when it is closed on the defrosting box 1, a sealing ring can be installed on the periphery facing away from the sealed box door 2, and a sealing groove that engages with the sealing ring can be installed on the defrosting box 1.

[0027] In this embodiment: the bottom of the inner wall of the thawing box 1 is provided with a slope 14, and a drain port 15 is provided on the back of the thawing box 1, with the drain port 15 located on one side of the slope 14.

[0028] When wastewater is generated in the defrosting box 1 due to the defrosting of frozen food, the wastewater can be discharged through the drain outlet 15. In order to prevent the wastewater discharged from the drain outlet 15 from polluting the environment, a collection container can be set on one side of the drain outlet 15 to collect the wastewater. The ramp 14 can prevent water accumulation at the bottom of the defrosting box 1.

[0029] In this embodiment: a movable support assembly is provided inside the defrosting box 1. The movable support assembly includes a slide rail 3, which is fixedly connected to the inner wall of the defrosting box 1. A slide plate 4 is slidably connected to the slide rail 3, and a support column 5 is fixedly connected to the slide plate 4.

[0030] In this application, there are multiple sets of movable support components, and the movable support components are arranged in pairs inside the defrosting box 1. The slide rail 3 is arranged in a "U" shape. There are multiple sets of support columns 5 on the slide plate 4. The slide plate 4 can slide linearly on the slide rail 3 by pulling it out. In this way, the structure mounted on the support column 5 can be movably arranged inside the defrosting box 1. In addition, in order to limit the slide plate 4 at the end of the slide rail 3, the end of the slide rail 3 should be in a blocked state.

[0031] In this embodiment: a storage box 6 is provided on the movable support assembly, the storage box 6 is fixedly connected to the support column 5, and multiple support protrusions 7 are fixedly connected to the bottom of the inner wall of the storage box 6.

[0032] The container 6 has a U-shaped structure and can be used to place frozen food. In order to increase the contact area between the frozen food and the thawing water, the support protrusion 7 can lift the frozen food so that there is a thawing area between the frozen food and the bottom of the container 6, which can ensure the thorough thawing of the frozen food.

[0033] In this embodiment: the container 6 is inclined, and multiple intercepting posts 16 and 2 intercepting posts 17 are fixedly connected to the bottom of the inner wall of the container 6.

[0034] The tilted design of the container 6 facilitates water discharge. Because of the tilted design of the container 6, multiple intercepting posts 16 and 17 can form two intercepting surfaces to prevent frozen food from sliding out of the container 6. This prevents frozen food from falling in the direction of drainage.

[0035] In this embodiment: a spray assembly is provided inside the thawing box 1. The spray assembly includes a water distribution plate 8, which is fixedly connected to the inner wall of the thawing box 1 and is located above the container box 6. Multiple nozzles 9 are fixedly connected to the bottom of the water distribution plate 8 and communicate with it. A three-way pipe 10 is fixedly connected to the side of the water distribution plate 8 and communicates with it. The three-way pipe 10 passes through the thawing box 1.

[0036] In this application, the number of spray components 1 is the same as the number of containers 6. The two ends of the three-way pipe 10 facing away from the water distribution plate 8 can be connected to two sets of water pumps respectively through existing pipe connection technology. One set of water pumps can be used to output thawing water, which is clean water at room temperature. The other set of water pumps can be used to output disinfectant water, which is a food-grade disinfectant that needs to be mixed and diluted with water. The disinfectant can be food-grade hypochlorous acid water, which is suitable for rinsing the surface of frozen meat, poultry, aquatic products, fruits and vegetables. Since the decomposition products of hypochlorous acid water are water, oxygen and chloride ions, there are no harmful residues, which meets the standards for food-grade safe disinfection. However, frozen foods need to be rinsed clean 1-3 minutes after contact with hypochlorous acid water. When disinfecting other types of frozen foods, an appropriate disinfectant can be selected according to the actual disinfection requirements. In order to reduce the investment cost of water pumps, multiple three-way pipes 10 can be connected to two sets of water pumps respectively using existing pipe connection technology.

[0037] In use, by starting the water pump that outputs disinfectant water, the water pump inputs disinfectant water into the water distribution plate 8 through the three-way pipe-10. The nozzle-9 on the water distribution plate 8 can spray disinfectant water above the frozen food, thus disinfecting the frozen food. Then, the supply of disinfectant water is stopped, and another set of water pumps outputs thawing water. Finally, the thawing water can be sprayed onto the frozen food through the nozzle-9, thus thawing the frozen food and rinsing off the disinfectant water on the frozen food.

[0038] In this embodiment: a second spray assembly is provided on the sealed door 2. Both the first and second spray assemblies are used for thawing and disinfecting frozen foods. The second spray assembly includes a water distribution pipe 11, which is fixedly connected to the back of the sealed door 2. A plurality of nozzles 12 are fixedly connected to one side of the water distribution pipe 11 and communicate with it. The nozzles 12 are located on one side of the container box 6. A three-way pipe 13 is fixedly connected to the other side of the water distribution pipe 11 and communicates with it. The three-way pipe 13 passes through the sealed door 2.

[0039] In this application, the principle of connecting the water pump to the three-way pipe 13 of the spray assembly 2 is the same as that of the three-way pipe 10. When in use, by starting the water pump that outputs disinfectant water, the water pump inputs disinfectant water into the water distribution pipe 11 through the three-way pipe 13. The nozzle 12 on the water distribution pipe 11 can spray disinfectant water from the side of the frozen food. The disinfectant water can rinse and disinfect the bottom of the frozen food through the support protrusion 7. Then, the supply of disinfectant water is stopped, and another set of water pumps outputs thawing water. Finally, the thawing water can be sprayed onto the frozen food through the nozzle 12. With the use of the nozzle 9, the frozen food can be fully thawed and disinfected, thereby improving the thawing efficiency of the frozen food.

[0040] Once the frozen food has finished thawing, the sealed door 2 can be opened, and the container 6 can be pulled out of the thawing box 1 via the movable support assembly.

[0041] In this embodiment, the two ends of the three-way pipe 10 and the three-way pipe 2 are respectively the disinfection inlet and the thawing inlet.

[0042] The disinfection inlet and the thawing inlet can be quickly switched between thawing water for thawing frozen foods and disinfection water for disinfection via corresponding water pumps.

[0043] All electrical components mentioned in the text are electrically connected to the main controller and power supply. The main controller can be a conventional and known device such as a computer, and the existing publicly available power connection technology will not be elaborated in the text.
