Description

Technical Field

[0001] The utility model relates to the technical field of nut processing, in particular to a nut vacuum cooling device. Background Art

[0002] In order to keep cooked food products and fruits and vegetables fresh and hygienic and to extend their shelf life, vacuum cooling is usually carried out. The principle of vacuum cooling is to use the heat absorbed when water vaporizes to cause its own cooling. Therefore, the vacuum cooling machine composed of a vacuum box, a water trap, a refrigeration unit and a rotary vane vacuum pump is used for cooling. It can fully achieve the vacuum degree required for pre-cooling of cooked food products and fruits and vegetables.

[0003] Existing vacuum cooling devices usually process cooked food and fruits and vegetables in the form of trays or racks placed in the cavity of a vacuum box for processing. However, for small and numerous materials such as nuts, the space taken up when spread out is inconvenient, making it inconvenient to place them efficiently.

[0004] An existing patent (Announcement No.: CN209246512U) discloses a vacuum cooler for high-protein nuts. The unique rack structure and the ring-shaped rack facilitate rapid evaporation of moisture from the nuts, removing heat. The multi-layered racks are arranged longitudinally to improve the stacking of nuts, allowing for more space and preventing over-stacked nuts from squeezing each other. Protective hems are provided on the racks to prevent nuts from falling, while ventilation holes are also provided to facilitate air circulation and aid moisture evaporation.

[0005] In response to the above problems, although the solution provided by the existing patent can stack nuts and perform evaporative cooling through the cooperation of components such as placement racks, in actual use, the nuts are in a state of being pressed against each other or even squeezed, resulting in part of the surface not being able to be fully evaporated and cooled, causing moisture accumulation. If complete evaporation is required, the cooling time needs to be extended, which affects the nuts that have completed evaporation, resulting in poor actual use effect. Summary of the Invention

[0006] The purpose of the utility model is to provide a vacuum cooling device for nuts, which can fully cool the nuts and avoid the accumulation or adhesion that causes the heat to be unable to dissipate, so as to solve the problems raised in the above-mentioned background technology.

[0007] To achieve the above object, the utility model provides the following technical solution: a vacuum cooling device for nuts, comprising a cooling box, a door panel movably connected to the front end of the cooling box, a cooling pipe extending from the rear end of the cooling box, a carrying plate fixed to the upper part of the interior of the cooling box, and a placement mechanism for spreading nuts provided below the carrying plate;

[0008] The placement mechanism includes a placement plate, which is fixed below the supporting plate inside the cooling box, and a limiting hole is provided on the inner wall of the placement plate. A rotating rod is passed through the interior of the supporting plate, and a rotating plate is fixed on the outer wall of the rotating rod near the placement plate. A roller is rotatably connected between the two axes at the bottom end of the rotating plate, and a connecting disk is fixed to the bottom end of the rotating rod.

[0009] Preferably, the rotating plate forms a rotating structure with the placement plate through a rotating rod, and the structure of the rotating plate is a U-shaped structure.

[0010] Preferably, a mounting chassis is fixed to the inner bottom end of the cooling box, and a driving mechanism is provided inside the mounting chassis.

[0011] Preferably, the driving mechanism includes a motor, which is embedded in the inner bottom end of the mounting chassis, and the power output end of the motor is connected to a rotating disk, and a damping spring is installed between the rotating disk and the connecting disk.

[0012] Preferably, the driving mechanism also includes a mounting hole, which is opened on one side of the damping spring at the top of the rotating disk, and an electromagnet is embedded inside the mounting hole. A connecting rod is slidably connected above the electromagnet inside the mounting hole, and a connecting block is installed on one side of the outer wall of the placement plate through bolts.

[0013] Preferably, the rotating disk is elastically connected to the connecting disk via a damping spring, and the rotating disk forms a rotating structure with the mounting chassis via a motor.

[0014] Preferably, a limit plate is fixed on the outer wall of one end of the rotating rod passing through the supporting plate, and a support rod is installed on the outer wall of the supporting plate facing the limit plate, and a limit groove is provided at the top of the supporting plate corresponding to the position of the support rod.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] 1. The placement plate and the limiting holes are used to hold the nuts while limiting their position, preventing them from rolling and sticking together, which would affect cooling. The rotating rod, rotating plate, and roller work together to turn the nuts over, allowing them to be fully cooled and avoiding accumulation or sticking, which would prevent heat from dissipating.

[0017] 2. Through the cooperation of the electromagnet and the connecting rod, the rotating disk and the connecting disk are moved closer or farther away, thereby adjusting the height of the rotating plate and the roller in the placement plate. When the nut is in contact with the placement plate, the nut is directly moved to form a centrifugal motion to separate from the corresponding gap of the connecting block and avoid the trouble of manual unloading. When it is at a normal height, the nut is in contact with the top of the nut to turn it over for sufficient cooling. The damping spring facilitates the reset of the connecting disk after the unloading is completed and the electromagnet is disconnected. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] 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 embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] The utility model provides a technical solution:

[0028] See also Figures 1 to 4, a nut vacuum cooling device includes a cooling box 1, the front end of the cooling box 1 is movably connected to a door panel 2, the rear end of the cooling box 1 is provided with a cooling pipe 3, a supporting plate 4 is fixed to the upper part of the interior of the cooling box 1, and a placing mechanism 5 for spreading nuts is provided below the supporting plate 4; the placing mechanism 5 includes a placing plate 502, the placing plate 502 is fixed below the supporting plate 4 inside the cooling box 1, a limiting hole 503 is provided on the inner wall of the placing plate 502, a rotating rod 501 is passed through the interior of the supporting plate 4, a rotating plate 504 is fixed on the outer wall of the rotating rod 501 near the placing plate 502, a roller 505 is rotatably connected between the two axes of the bottom end of the rotating plate 504, a connecting disk 506 is fixed to the bottom end of the rotating rod 501, and the rotating plate 504 forms a rotating structure through the rotating rod 501 and the placing plate 502, and the structure of the rotating plate 504 is a U-shaped structure.

[0029] By adopting the above technical solution, first, the cooling box 1 and the door panel 2 form a vacuum box body, and then the vacuum pump, refrigeration unit and other equipment are cooperated, and then the material inside the cooling box 1 is vacuum cooled through the cooling pipe 3. Under the limit of the supporting plate 4, the rotating rod 501 rotates to drive the rotating plate 504 to rotate, and at the same time, the roller 505 is allowed to roll on the top of the nuts, and the nuts on the placement plate 502 are turned over to avoid accumulation or adhesion that causes moisture or heat to be unable to be completely dissipated. The rotation of the roller 505 prevents the nuts from being too hard and causing them to be damaged. The hole spacing of the limiting hole 503 is slightly smaller than the size of the nut, which can limit the nuts to avoid excessive rolling and adhesion, and at the same time, it can avoid the bottom of the nuts and the placement plate 502 from being adhered and unable to be fully cooled.

[0030] Specifically, such as Figures 3 to 5 As shown, the bottom end of the interior of the cooling box 1 is fixed with a mounting chassis 6, and the interior of the mounting chassis 6 is provided with a driving mechanism 7, which includes a motor 701, which is embedded in the bottom end of the interior of the mounting chassis 6, and the power output end of the motor 701 is connected to a rotating disk 702, and a damping spring 703 is installed between the rotating disk 702 and the connecting disk 506. The driving mechanism 7 also includes a mounting hole 704, which is opened on one side of the damping spring 703 at the top of the rotating disk 702, and an electromagnet 705 is embedded in the interior of the mounting hole 704. A connecting rod 706 is slidably connected above the electromagnet 705 inside the hole 704, and a connecting block 707 is installed on one side of the outer wall of the placement plate 502 through a bolt. The rotating disk 702 is elastically connected to the connecting disk 506 through the damping spring 703. The rotating disk 702 forms a rotating structure with the mounting chassis 6 through the motor 701. The rotating rod 501 passes through the outer wall of one end of the supporting plate 4 and is fixed with a limiting plate 8. The limiting plate 8 is installed with a support rod 9 facing the outer wall of the supporting plate 4, and a limiting groove 10 is provided at the top of the supporting plate 4 corresponding to the position of the support rod 9.

[0031] By adopting the above technical solution, the motor 701 drives the rotating disk 702 to rotate, and the rotating disk 702 pushes the connecting disk 506 through the damping spring 703 to prevent the electromagnet 705 and the connecting rod 706 from fitting together, and through the limitation of the mounting hole 704, it can stably drive the connecting disk 506 to allow the placement mechanism 5 to perform the sharing operation. When it is necessary to unload the material, after the connecting block 707 is disassembled by the bolts, the storage container is aligned with the corresponding notch of the connecting block 707, the electromagnet 705 is started to magnetically attract the connecting rod 706, and the damping spring is compressed. 703, so that the roller 505 fits the placement plate 502, thereby driving the nuts to perform centrifugal motion during the rotation process, and escapes through the notch for unloading to avoid the trouble of manual picking. When the rotating rod 501 rotates, it cooperates with the limit plate 8 and the support rod 9 to facilitate stable sliding along the limit groove 10 of the bearing plate 4. The bottom end of the support rod 9 is embedded with a universal wheel to improve the sliding smoothness. At the same time, the support rod 9 is in the form of a telescopic rod and is provided with a spring inside. It can be adjusted according to the expansion and contraction of the damping spring 703 to maintain the rotation stability of the rotating rod 501.

[0032] Working principle: First, a vacuum box is formed by the cooling box 1 and the door panel 2, and the nuts are vacuum cooled through the cooling pipe 3 and the vacuum pump, refrigeration unit, etc. The motor 701 embedded in the mounting chassis 6 drives the rotating disk 702, and the connecting rod 706 is driven through the mounting hole 704 to rotate the connecting disk 506. The connecting disk 506 drives the rotating rod 501, so that the rotating plate 504 rotates on the placing plate 502. The rotating plate 504 rotates the connected roller 505 to fit the nuts and turn them over. Through the cooperation of the limiting hole 503, the limiting nuts are The nuts can be fully vacuum-cooled at the same time. When the cooling is completed and the material needs to be unloaded, the door panel 2 is opened to disassemble the corresponding connecting block 707, and the storage container is aligned with the corresponding notch of the disassembly and assembly connecting block 707. The electromagnet 705 is started to adsorb the metal connecting rod 706 to compress the damping spring 703, so that the roller 505 fits the placement plate 502 and pushes the nut to perform centrifugal motion and detach through the notch. When the rotating rod 501 rotates, it drives the limit plate 8, allowing the support rod 9 to stably rotate along the limit groove 10 opened on the bearing plate 4, thereby improving the stability of the rotation process of the rotating rod 501.

Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present invention.
