[0002] Cryopreservation involves cooling to extremely low temperatures, at which any enzyme activity or chemical activity that could damage the biological material in question is effectively prevented. Frozen foods are divided into chilled foods and frozen foods. Frozen foods are easy to preserve and are widely used in the production, transportation, and storage of perishable foods such as meat, poultry, aquatic products, dairy products, eggs, vegetables, and fruits. Fruits contain a large amount of vitamins and other nutrients and are rich in nutritional value. During the storage of fruits, freezing is often carried out.

[0003] However, existing cooling devices still have certain drawbacks. During use, traditional cooling devices have a slow cooling speed and uneven cooling of the fruit, which leads to a decline in fruit quality. Since the fruit is relatively soft before freezing, the existing devices are not convenient for layering the fruit, which causes the fruit to be crushed and damaged.

[0004] Based on this, a layered cooling device for post-harvest fruit preservation is provided, which can eliminate the drawbacks of existing devices. Utility Model Content

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0022] In one embodiment, such as Figure 1 - Figure 4 As shown, a layered cooling device for post-harvest preservation of fruit includes a freezer 1, with two storage cabinets 11 opened on both sides of the interior of the freezer 1, and two fixing slots 12 opened on both sides of the interior of the storage cabinets 11. An adjustment assembly is installed inside the fixed groove 12. The adjustment assembly includes a lifting frame 2, which is installed inside the fixed groove 12. A positioning plate 21 is installed on one side of the inside of the lifting frame 2, and a lifting block 22 is slidably connected inside the lifting frame 2. A limit assembly is installed on the top of the lifting block 22; A movable component is installed on one side of the lifting block 22.

[0023] In this embodiment, the left storage cabinet 11 is used to pre-cool the fruit, and then the right storage cabinet 11 of the same specification is used for cooling. The height of the moving component is adjusted by the lifting block 22 moving up and down inside the lifting frame 2. The moving component is limited and supported by the limiting component, and the movement of the moving component is positioned by the positioning component, which improves the convenience and practicality of the device.

[0024] In one embodiment, such as Figure 1 and Figure 2 As shown, a base 13 is installed at the bottom of the freezer 1, and two sealing doors 14 are rotatably connected to the front of the freezer 1 to seal one side of the freezer 1.

[0025] In one embodiment, such as Figure 1 and Figure 2 As shown, a cooling assembly is installed at the rear of the freezer 1 to cool the two storage cabinets 11 individually.

[0026] In one embodiment, such as Figure 1 and Figure 2 As shown, the cooling assembly includes a cold air blower 15, which is installed at the rear of the freezer 1. An air collector shroud 16 is installed at the input end of the cold air blower 15 and is installed at the top of the freezer 1. An air blower plate 17 is installed at the output end of the cold air blower 15 and is installed at the bottom of the storage cabinet 11.

[0027] In one embodiment, such as Figure 1 and Figure 3 As shown, the limiting component includes a connecting block 23, which is installed on the top of the lifting block 22. A limiting plate 24 is slidably connected inside the connecting block 23. A pull ring 25 is installed on one side of the limiting plate 24, and two return springs 26 are installed on both sides of one side of the pull ring 25. One side of the return springs 26 is connected to the connecting block 23. By pulling the pull ring 25, the limiting plate 24 is driven to slide inside the connecting block 23, thereby causing the limiting plate 24 to disengage from the positioning plate 21. After releasing the pull ring 25, the return springs 26 automatically rebound, causing the limiting plate 24 to insert into the positioning plate 21 for limiting.

[0028] In one embodiment, such as Figure 1 and Figure 4 As shown, the moving component includes a support frame 3, which is installed on one side of the lifting block 22. A sliding plate 31 is slidably connected inside the support frame 3, and a grid frame 32 is installed on one side of the sliding plate 31. The grid frame 32 is moved out by the sliding plate 31 sliding inside the support frame 3, and the fruit is placed through the grid frame 32.

[0029] In one embodiment, such as Figure 1 and Figure 4 As shown, two positioning components are installed on both sides of one side of the sliding plate 31 to limit the sliding of the sliding plate 31.

[0030] In one embodiment, such as Figure 1 and Figure 4 As shown, the positioning component includes a connecting spring 33, which is installed on both sides of one side of the sliding plate 31. A limiting block 34 is installed on one side of the connecting spring 33. The limiting block 34 is slidably connected to the inside of one side of the sliding plate 31. By pulling the grid frame 32, the limiting block 34 is squeezed by the support frame 3, causing the connecting spring 33 to retract, thereby causing the limiting block 34 to retract into the interior of the sliding plate 31, so as to facilitate the removal of the grid frame 32.

[0031] The above embodiment discloses a layered cooling device for post-harvest fruit preservation. The base 13 supports the bottom of the freezer 1. Two separate cooling components individually cool two storage cabinets 11, pre-cooling the fruit in the left storage cabinet 11 and then cooling it in the right storage cabinet 11, improving the cooling effect and uniformity. The operation of the cold air fan 15 draws air from the top of the storage cabinets 11 through the air collector 16 for cooling, and then blows cold air from the bottom of the storage cabinets 11 through the blower plate 17, thereby promoting air circulation inside the storage cabinets 11 and improving the cooling effect on the fruit. Pulling the pull ring 25 causes the limiting plate 24 to slide inside the connecting block 23, thus disengaging the limiting plate 24 from the positioning plate 21. The lifting block 22 then... The height of the grid frame 32 is adjusted by sliding it up and down inside the lifting frame 2. When the grid frame 32 moves to the appropriate height, the pull ring 25 is released, and the connecting spring 33 automatically rebounds, causing the limiting plate 24 to insert into the positioning plate 21, thereby positioning the height of the grid frame 32. By pulling the grid frame 32, it slides inside the support frame 3, and the positioning component limits the grid frame 32. The fruit is placed inside the grid frame 32, which facilitates layered cooling of the fruit and avoids the problem of crushing and damage caused by fruit stacking. When it is necessary to remove the grid frame 32, the grid frame 32 is pulled forcefully, causing the support frame 3 to squeeze the limiting block 34, thereby causing the connecting spring 33 to retract and drive the limiting block 34 to retract, so that the grid frame 32 can be removed, which improves the convenience and practicality of the device.

Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
