Description

Technical Field

[0001] This utility model relates to the field of macadamia nut processing technology, and in particular to a vacuum freeze-drying apparatus for macadamia nuts. Background Technology

[0002] Macadamia nuts have the highest economic value and are known as the "King of Nuts." They have high nutritional and medicinal value and are a type of edible nut with high oil content, rich nutrients, and a unique flavor. The kernel's nutritional components are mainly fat, with a content of over 75%, and most of it is unsaturated fatty acids. It also contains relatively rich sugars, starches, proteins, amino acids, and minerals such as Ca, Zn, Mg, Fe, and Mn. Before storage, macadamia nuts need to be dried, which increases their storage time. Macadamia nuts are dried using a vacuum freeze dryer.

[0003] For example, patent CN220911799U discloses a vacuum freeze dryer for nuts, relating to the field of vacuum freeze dryer technology. It includes a machine body, with a placement rack on top of the machine body. The placement rack includes a base, a rotating seat, a mounting frame, and a tray. The rotating seat is rotatably connected to the top of the base, and a U-shaped mounting frame is fixedly mounted on the rotating seat. The inner cavity of the mounting frame contains a tray. A groove is formed at the bottom of the rotating seat, and a toothed ring is fitted onto the inner wall of the groove. A gear on the base, driven by a motor, meshes with the toothed ring.

[0004] In the aforementioned vacuum freeze dryer, the macadamia nuts on multiple circular trays still require manual handling, which wastes time and reduces the processing efficiency of subsequent batches. Therefore, this application provides a vacuum freeze dryer for macadamia nuts to meet this need. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a vacuum freeze-drying device for macadamia nuts, so as to solve the problem that the existing device still requires personnel to manually pick up macadamia nuts one by one when feeding them onto multiple round trays, which wastes time and reduces the processing efficiency of the next batch of macadamia nuts.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0007] A vacuum freeze-drying apparatus for macadamia nuts includes a main body. A pre-loading slot is provided on the top of the main body, and a cover is installed in the middle of the pre-loading slot. A disassembly / assembly mechanism is installed at the lower end of the cover and inside the pre-loading slot. A fixed mounting frame is installed above the middle of the pre-loading slot, and tray racks are distributed inside the fixed mounting frame. A spreading mechanism is installed in the middle of the fixed mounting frame. A linked feeding mechanism is jointly installed on both sides of the fixed mounting frame and the inner and outer sides of multiple tray racks. The linked feeding mechanism includes lifting components installed on both sides of the fixed mounting frame. Fixed rods are fixed on both sides of the middle of the tray racks, and hinges are installed on both sides of the two fixed rods. A tray is installed on the inner side of the two hinges. Feeding components are installed on both sides of the three tray racks.

[0008] Optionally, the lifting assembly includes a fixed block, which is symmetrically fixed on both sides of the upper and lower ends of the fixed frame. A transmission screw is installed inside one side of the fixed block, and a second motor is installed at one end of the transmission screw. Screw sleeves are distributed around the transmission screw, and a connecting guide is fixed inside the multiple screw sleeves. A guide sleeve is fixed on the other side of the connecting guide, and a guide rod is fixed inside the fixed block on the other side. Connecting rods are fixed on both sides above the connecting guide, and a movable wheel frame is installed above the two connecting rods.

[0009] Optionally, the guide rod forms a movable guide connection with the guide sleeves fixed at one end of the multiple connected guide frames.

[0010] Optionally, the middle section of the connecting guide is distributed in a semi-circular arc shape, and connecting rods and movable wheel frames are symmetrically provided on both sides above the connecting guide.

[0011] Optionally, the unloading assembly includes guide tube frames, which are symmetrically arranged on both sides of the lower end of multiple pallet frames. The ends of the multiple guide tube frames are connected to connecting pipes, and the ends of two connecting pipes are connected to a confluence pipe. The ends of two confluence pipes are connected to unloading telescopic pipes.

[0012] Optionally, the confluence pipes are distributed at an angle, and the discharge telescopic pipe connected to the end of the confluence pipes is also designed at an angle.

[0013] Optionally, the disassembly and assembly mechanism includes an internal thread, which is formed on the inner wall of the pre-assembly groove. The lower section of the machine cover is provided with external threads, and a second sealing gasket is provided at the lower end of the machine cover. A first sealing gasket is provided at the bottom periphery of the pre-assembly groove.

[0014] Optionally, a threaded connection is formed between the inner side of the internal thread and the periphery of the external thread.

[0015] Optionally, the spreading mechanism includes a first motor, which is installed at the bottom of the lowest tray frame inside the fixed frame. The output end of the first motor is connected to a rotating rod, and the periphery of the rotating rod is provided with fixed sleeves. Both ends of the multiple fixed sleeves are connected to levers, and the bottom end of the levers is provided with rake heads.

[0016] Optionally, the rake heads are evenly spaced along the bottom end of the lever.

[0017] Compared with the prior art, this utility model has at least the following beneficial effects:

[0018] In the above scheme, by setting up a linkage feeding mechanism, after the device finishes processing macadamia nuts, the operator removes the machine cover and then starts the second motor to rotate the transmission screw. At this time, the three screw sleeves located around the transmission screw will carry the connecting guide frame and the connecting rods and movable wheel frames on both sides above, and will descend under the guidance of the guide sleeves and guide rods. In this state, the three pairs of pallets will tilt and move in contact with their respective descending movable wheel frames by utilizing the mobility of the hinges set on the relatively fixed rods. At this time, the macadamia nuts located on the three pairs of pallets will naturally roll into the three pairs of pre-set guide tube frames along the tilt angle. Thus, the three pairs of guide tube frames can sequentially guide the nuts into the feeding telescopic tube through the connecting pipe and the merging pipe. The operator can connect one end of the feeding telescopic tube to the feeding collection area in advance, which is portable and practical.

[0019] By setting up a disassembly and assembly mechanism, when in use, personnel can use the internal and external threads to remove the cover from the pre-installed slot on the top of the main body.

[0020] By setting up a spreading mechanism, personnel evenly pour the macadamia nuts to be vacuum freeze-dried into multiple trays inside the fixed rack in batches. Then, the disassembly and assembly mechanism is used to reset the machine cover. The second sealing gasket at the bottom of the machine cover and the first sealing gasket around the bottom of the pre-loading groove are used to ensure a seal. Then, during the vacuum freeze-drying process, personnel can start the first motor to make the rotating rod, along with multiple fixed sleeves and two side levers, rotate at a constant speed along the upper part of the tray rack. The rake heads set below the levers ensure that the macadamia nuts on the trays are always in motion, thereby increasing the rate of moisture sublimation and improving the drying efficiency.

[0035] like Figures 1 to 5As shown, an embodiment of this utility model provides a vacuum freeze-drying device for macadamia nuts, including a main body 1. A pre-loading groove 2 is provided on the upper part of the main body 1, and a machine cover 8 is installed in the middle of the pre-loading groove 2. A disassembly and assembly mechanism 3 is installed at the lower end of the machine cover 8 and on the inner side of the pre-loading groove 2. A fixed mounting frame 4 is installed above the middle of the pre-loading groove 2, and tray racks 5 are provided inside the fixed mounting frame 4. A spreading mechanism 6 is installed in the middle of the fixed mounting frame 4. The two sides of the fixed mounting frame 4 and the inner and outer sides of the multiple tray racks 5 are connected together. The machine is equipped with a linkage feeding mechanism 7 and a disassembly and assembly mechanism 3, which includes an internal thread 31. The internal thread 31 is opened on the inner wall of the pre-assembly groove 2. The lower part of the machine cover 8 is provided with external threads 32. The lower end of the machine cover 8 is provided with a second sealing gasket 34. The bottom end of the pre-assembly groove 2 is provided with a first sealing gasket 33. The inner side of the internal thread 31 and the periphery of the external thread 32 form a threaded connection. When in use, the personnel use the internal thread 31 and the external thread 32 to remove the machine cover 8 from the pre-assembly groove 2 provided above the main body 1.

[0036] The spreading mechanism 6 includes a first motor 61, which is installed at the bottom of the lowest tray 5 inside the fixed frame 4. The output end of the first motor 61 is connected to a rotating rod 62, and fixed sleeves 63 are distributed around the rotating rod 62. Both ends of the multiple fixed sleeves 63 are connected to levers 64, and rake heads 65 are distributed at the bottom of the levers 64. The rake heads 65 are evenly spaced along the bottom of the levers 64. Personnel pour the macadamia nuts to be vacuum freeze-dried evenly onto the multiple trays 5 inside the fixed frame 4 in batches. Then... The machine cover 8 is then reset using the disassembly and assembly mechanism 3. The second sealing gasket 34 at the bottom of the machine cover 8 and the first sealing gasket 33 around the bottom of the pre-assembly groove 2 are used to ensure a seal between them. Then, during the vacuum freeze-drying process, the operator can start the first motor 61 to make the rotating rod 62 rotate at a constant speed along the upper part of the tray frame 5, carrying multiple fixed sleeves 63 and two side levers 64. The rake heads 65 below the levers 64 can ensure that the macadamia nuts on the tray 74 are always in motion, thereby increasing the rate of moisture sublimation and improving the drying efficiency.

[0037] Furthermore, the linkage unloading mechanism 7 includes a lifting assembly 71, which is installed on both sides of the fixed frame 4. The lifting assembly 71 includes a fixing block 711, which is symmetrically fixed on both the upper and lower ends of the fixed frame 4. A transmission screw 712 is installed inside one of the fixing blocks 711, and a second motor 713 is installed at one end of the transmission screw 712. Screw sleeves 714 are distributed around the transmission screw 712, and a connecting guide frame 715 is fixed inside the multiple screw sleeves 714. A guide sleeve 716 is fixed on the other side of the connecting guide frame 715, and a guide rod 717 is fixed inside the other fixing block 711. A movable guide connection is formed between the guide sleeves 716 fixed at one end of the multiple connecting guide frames 715. Connecting rods 718 are fixed on both sides of the upper part of the connecting guide frame 715, and movable wheel frames 719 are installed above the two connecting rods 718. The middle section of the connecting guide frame 715 is distributed in a semi-circular arc shape, and connecting rods 718 and movable wheel frames 719 are symmetrically arranged on both sides of the upper part of the connecting guide frame 715. Fixed rods 72 are fixed on both sides of the middle part of the pallet frame 5, and hinges 73 are installed on both sides of the two fixed rods 72. Support plates 74 are installed on the inner sides of the two hinges 73. Feeding assemblies 75 are installed on both sides of the three pallet frames 5. The feeding assembly 75 includes a guide tube frame 751. Furthermore, guide tube frames 751 are symmetrically distributed on both sides of the lower ends of multiple tray frames 5. The ends of the multiple guide tube frames 751 are connected to connecting pipes 752, and the ends of two connecting pipes 752 are connected to converging pipes 753. The ends of two converging pipes 753 are connected to discharge telescopic pipes 754. The converging pipes 753 are distributed at an angle, and the discharge telescopic pipes 754 connected to the ends of the converging pipes 753 are also designed at an angle. After the device finishes processing macadamia nuts, the operator removes the machine cover 8, and then starts the second motor 713 to rotate the transmission screw 712. At this time, the three screw sleeves 714 distributed around the transmission screw 712 will carry the connecting guide frame 715 and the two upper ones. The connecting rod 718 and movable wheel frame 719 on the side work together with the guide sleeve 716 and guide rod 717 to perform the descent operation. In this state, the three pairs of pallets 74 will use the mobility of the hinge 73 set on the relative fixed rod 72 to adhere to their respective movable wheel frames 719 and tilt. At this time, the macadamia nuts set on the three pairs of pallets 74 will naturally roll into the three pairs of pre-set guide tube frames 751 along the tilt angle. Thus, the three pairs of guide tube frames 751 can sequentially guide the nuts into the feeding telescopic tube 754 through the connecting tube 752 and the merging tube 753. Personnel can connect one end of the feeding telescopic tube 754 to the feeding collection area in advance, which is portable and practical.

[0038] The working principle of the technical solution provided by this utility model is as follows:

[0039] In use, the operator first removes the cover 8 from the pre-loading slot 2 above the main body 1 using the internal thread 31 and external thread 32. Then, the operator evenly pours the macadamia nuts to be vacuum freeze-dried into multiple tray racks 5 inside the fixed mounting frame 4. Next, the operator uses the disassembly and assembly mechanism 3 to reset the cover 8. The second sealing gasket 34 at the bottom of the cover 8 and the first sealing gasket 33 around the bottom of the pre-loading slot 2 ensure a seal. During vacuum freeze-drying, the operator can start the first motor 61 to make the rotating rod 62 rotate at a constant speed along the upper part of the tray rack 5, carrying multiple fixed sleeves 63 and two side levers 64. The rake heads 65 below the levers 64 ensure that the macadamia nuts on the tray 74 are always in motion, thereby increasing the rate of moisture sublimation and improving drying efficiency. Finally, after the device has finished processing the macadamia nuts, the operator removes the tray. The machine cover 8 is then activated, and the second motor 713 is started to rotate the transmission screw 712. At this time, the three screw sleeves 714 located around the transmission screw 712 will lower the machine by means of the connecting guide frame 715, the connecting rods 718 on both sides above, and the movable wheel frame 719, in coordination with the guide sleeve 716 and the guide rod 717. In this state, the three pairs of pallets 74 will tilt and move in contact with the movable wheel frame 719 during their descent by means of the hinges 73 on the relatively fixed rod 72. At this time, the macadamia nuts located on the three pairs of pallets 74 will naturally roll into the three pairs of pre-set guide tube frames 751 along the tilt angle. Thus, the three pairs of guide tube frames 751 can sequentially guide the nuts into the feeding telescopic tube 754 through the connecting tube 752 and the merging tube 753. Personnel can connect one end of the feeding telescopic tube 754 to the feeding collection area in advance, which is portable and practical.
