[0002] The high-efficiency pre-freezing layered shelf device for freeze-dried fruits is a key component in the fruit freeze-drying process, designed to improve pre-freezing efficiency and the quality of freeze-dried fruits. It typically consists of multiple layers of shelves, with a certain spacing between each layer to allow for the circulation of cold air, ensuring uniform heating and cooling of the fruit. The shelves are generally made of materials with good thermal conductivity, such as stainless steel, to ensure rapid heat transfer.

[0003] In existing technology, during the pre-freezing process, the fruit is evenly placed on each shelf of a tiered rack, and then the refrigeration system of the freeze dryer is activated. Cold air circulates throughout the device through the gaps between the shelves and the ventilation holes on the shelves, thus completing the pre-freezing. However, when placing the fruit, workers need to first place the fruit on the shelf and then insert the shelf into the rack. But when inserting the shelf into the rack, the weight of the fruit may increase the difficulty of placement, and it may be placed off-center or even shake. Utility Model Content

[0024] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0025] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0026] Example 1, such as Figures 1-5 As shown, this utility model provides a high-efficiency pre-freezing layered shelf device for freeze-dried fruits, including a base 1. Two uprights 4 are symmetrically installed on the top of the base 1. Multiple evenly distributed movable frames 5 are slidably installed on the outer wall of the uprights 4. The outer wall of the movable frames 5 is provided with slots 16. The bottom surface of the slots 16 is provided with storage grooves 17. Multiple evenly distributed second rollers 18 are rotatably installed on the inner wall of the storage grooves 17. The inner wall of the slots 16 is provided with placement grooves 19. The inner wall of the placement grooves 19 is provided with threaded holes 20. The threaded holes 20 are threadedly connected to the first threaded rod 21. A handle 22 is fixedly installed at one end of the first threaded rod 21. A locking block 23 is movably connected to the other end of the first threaded rod 21. Multiple evenly distributed trays 6 are arranged between the two uprights 4. Connecting plates 7 are fixedly installed on both sides of the outer side of the trays 6. The outer wall of the connecting plates 7 is provided with locking grooves 24.

[0027] The effect achieved by the entire embodiment 1 is that, in use, the operator inserts the two connecting plates 7 into the two slots 16 respectively. At this time, the bottom of the connecting plate 7 contacts the second roller 18. The operator pushes the tray 6, and the second roller 18 rotates to reduce friction, so that the operator can easily place the tray 6. When the slot 24 moves to the side of the block 23, the operator rotates the handle 22, and the first threaded rod 21 rotates, so that the block 23 moves along the placement slot 19 until the block 23 enters the slot 24, thus completing the fixation and preventing the tray 6 from shaking.

[0028] Example 2, as Figures 1-5 As shown, further, a limiting groove 10 is opened inside the movable frame 5. A spring 11 is fixedly installed on the inner wall of the limiting groove 10. A limiting plate 12 is fixedly installed on one end of the spring 11. A fixing plate 13 is fixedly installed on the outer wall of the limiting plate 12. One end of the fixing plate 13 passes through the limiting groove 10. A connecting rod 14 is fixedly installed on the outer wall of the limiting plate 12. One end of the connecting rod 14 passes through the limiting groove 10 and is fixedly installed with a pull plate 15.

[0029] Furthermore, the outer wall of the column 4 is provided with multiple evenly distributed fixing grooves 8.

[0030] Furthermore, the outer wall of the connecting plate 7 is provided with a positioning groove 25, and the inner wall of the slot 16 is fixedly installed with a positioning plate 26. When the operator inserts the connecting plate 7 into the slot 16, the positioning plate 26 enters the positioning groove 25. When the outer wall of the positioning plate 26 is in contact with the inner side wall of the positioning groove 25, the slot 24 moves to the side of the block 23 to facilitate positioning and prevent the connecting plate 7 from moving excessively.

[0031] Furthermore, the inner wall of the tray 6 has multiple evenly distributed through holes 27 to facilitate the passage of cold air.

[0032] Furthermore, multiple evenly distributed support blocks 28 are fixedly installed on the inner wall of the tray 6. When in use, the staff places the fruit in the tray 6, and the fruit contacts the support blocks 28. The fruit only contacts the tray 6 through the support blocks 28, reducing the contact area and preventing freezing and sticking.

[0033] Furthermore, an installation frame 3 is fixedly installed on the inner wall of the base 1. A control groove 29 is opened at the bottom of the installation frame 3. A second threaded rod 32 is rotatably installed inside the control groove 29. The top of the second threaded rod 32 passes through the installation frame 3 and is fixedly installed on a turntable 33. A handle 34 is fixedly installed on the top of the turntable 33. A lifting plate 30 is slidably installed inside the control groove 29. A threaded groove 31 is opened at the top of the lifting plate 30. The second threaded rod 32 is threadedly connected to the threaded groove 31. Four evenly distributed third rollers 35 are provided at the bottom of the lifting plate 30.

[0034] Furthermore, support frames 2 are fixedly installed at the four corners of the bottom of the base 1 to support the device.

[0035] Furthermore, the inner wall of the movable frame 5 is provided with two first rollers 9, which facilitates the movement of the movable frame 5.

[0036] Furthermore, the outer wall of the connecting plate 7 fits into the inner wall of the slot 16, and the outer wall of the locking block 23 fits into the inner wall of the slot 24. When the connecting plate 7 enters the slot 16 and the locking block 23 enters the slot 24, the tray 6 can be fixed and will not shake.

[0037] The effect achieved by the entire embodiment 2 is that when adjusting the distance between the trays 6, the worker pulls the pull plate 15, and the pull plate 15 drives the fixed plate 13 away from the fixed groove 8 through the connecting rod 14. The spring 11 is compressed, and then the worker pulls the moving frame 5. The moving frame 5 moves along the column 4 until the adjustment is completed. The worker releases the pull plate 15, and the elastic force of the spring 11 pushes the fixed plate 13 into the fixed groove 8. At this time, the moving frame 5 is fixed, and the adjustment can be completed in this way, improving the space utilization rate.

[0038] Working principle: In use, the operator places the fruit in the tray 6, with the fruit contacting the support block 28. The fruit only contacts the tray 6 through the support block 28, reducing the contact area and preventing freezing and sticking. Then, the operator inserts the two connecting plates 7 into the two slots 16 respectively. At this time, the bottom of the connecting plate 7 contacts the second roller 18. The operator pushes the tray 6, and the second roller 18 rotates, reducing friction. This makes it easier for the operator to place the tray 6. When the slot 24 moves to the side of the locking block 23, the operator rotates the handle 22, and the first threaded rod 21 rotates, causing the locking block 23 to move along the placement groove 19 until the locking block 23 enters the slot 24. This completes the fixation and prevents the tray 6 from shaking. When adjusting the distance between trays 6, the operator pulls the pull plate 15. The pull plate 15, through the connecting rod 14, moves the fixing plate 13 away from the fixing groove 8, compressing the spring 11. Then, the operator pulls the moving frame 5, which moves along the column 4 until the adjustment is complete. The operator releases the pull plate 15, and the spring force of the spring 11 pushes the fixing plate 13 into the fixing groove 8, at which point the moving frame 5 is fixed. This completes the adjustment and improves space utilization. During movement, the third roller 35 facilitates the device's entry into the freeze dryer. When stopping, the operator turns the handle 34, causing the second threaded rod 32 to rotate. The lifting plate 30 rises along the control groove 29 until it is fully inside the control groove 29. At this point, the support frame 2 contacts the inner wall of the machine, and the third roller 35 is suspended in the air, thus completing the placement.

[0039] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
