[0012] The technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0013] Therefore, this utility model provides a quick-freezing and preservation device for fresh areca nuts. (See also:) Figure 1 - Figure 3 As shown, it includes a structural box 1, with a quick-freezing chamber 2 located at the lower part of the structural box 1, and a screening chamber 3 located at the upper part of the structural box 1. An inclined mounting frame 4 is fixed inside the screening chamber 3, and multiple rotating rollers 5 are mounted on the mounting frame 4. The distance between the rotating rollers 5 gradually increases from top to bottom. A drive power supply 6 is mounted on the outer surface of the structural box 1, and the drive power supply 6 acts on the rotating rollers 5. A feed hopper 7 is mounted at one end of the top of the structural box 1, and the bottom of the feed hopper 7 communicates with the screening chamber 3 through a connecting port. The drive power supply 6 provides the driving force for the rotation of the rotating rollers 5, enabling the sorting of fresh areca nuts by size. The closer to the top of the mounting frame 4, the smaller the areca nuts falling; the closer to the bottom of the mounting frame 4, the larger the areca nuts falling, achieving an effective sorting effect.

[0014] A rotating shaft 8 is rotatably mounted inside the cavity of the feeding hopper 7. A lever plate 9 is mounted on the rotating shaft 8, with the lever plates 9 alternately and equidistantly mounted on the rotating shaft 8. A drive motor 10 is mounted on the vertical structural surface of the feeding hopper 7, and the output shaft of the drive motor 10 is connected to one end of the rotating shaft 8. The feeding hopper 7 is located at the top of the mounting frame 4. Because fresh areca nuts contain a certain amount of moisture, the accumulated areca nuts do not easily flow. When a large amount of fresh areca nuts is poured into the feeding hopper 7, the fresh areca nuts tend to accumulate and cannot fall downwards. The drive motor 10 can be activated, causing the rotating shaft 8 to rotate the lever plate 9, thus pushing the accumulated areca nuts into the screening chamber 3, ensuring the smooth falling of the fresh areca nuts inside the feeding hopper 7.

[0015] A connecting frame is fixed in the middle of the structural box 1, and a conical trough 11 is opened on the top of the connecting frame. The bottom of the conical trough 11 is connected to the quick-freezing chamber 2. A partition plate 18 is installed between each pair of conical troughs 11, and the top of the partition plate 18 is located at the bottom of the drive power supply 6. The partition plate 18 can ensure that the sorted fresh areca nuts fall into the receiving box 15 at the corresponding position.

[0016] Multiple receiving boxes 15 are installed inside the screening chamber 3. Each receiving box 15 has a receiving cavity at its top. A pull-out opening is located on one side of the quick-freezing chamber 2, and a sealing door 16 is symmetrically mounted within this opening. Pull handles 17 are symmetrically connected to the outer surface of each sealing door 16. When collecting the quick-frozen areca nuts, a pulling force can be applied to the sealing door 16 by pulling the handle 17. This opens the sealing door 16, allowing the receiving box 15 to be pulled out, thus facilitating the collection of the quick-frozen areca nuts.

[0017] Each conical trough 11 has an internal telescopic hole 12, and a telescopic partition 13 is installed inside the telescopic hole 12. A mounting shell 14 is installed on the outer side of the structural box 1 away from the drive power source 6. An electric push rod is installed in the mounting shell 14, and the pushing end of the electric push rod is connected to the telescopic partition 13 at the corresponding position. The electric push rod inside the mounting shell 14 operates intermittently, so that too many areca nuts do not accumulate on the top of the telescopic partition 13. The areca nuts of the same batch fall into the receiving box 15 at equal intervals, which can ensure the quick-freezing effect of each batch of areca nuts and avoid the instantaneous accumulation of a large number of areca nuts inside the receiving box 15, which would affect the quick-freezing effect.

[0018] The horizontal cross-section of the telescopic partition 13 is larger than the bottom horizontal cross-section of the conical trough 11, and the bottom of the telescopic partition 13 is inlaid with an expanded polystyrene board. The telescopic partition 13 can not only lift the areca nuts, but also achieve the effect of separating and heat preservation, ensuring that the temperature difference between the quick-freezing chamber 2 and the screening chamber 3 does not change too much.

[0019] During operation, the structure of the screening chamber 3, rotating roller 5, and telescopic partition 13 allows cleaned areca nuts to be poured into the feed hopper 7. The drive motor 10 is activated, and the rotating shaft 8 drives the actuating plate 9 to rotate. Fresh areca nuts accumulated inside the feed hopper 7 enter the screening chamber 3 and fall onto the top of the rotating roller 5. The drive power supply 6 operates, and the rotating roller 5 rotates, causing smaller areca nuts to gradually fall off. The falling areca nuts pass through a conical trough 11 onto the top of the telescopic partition 13. The electric push rod inside the mounting shell 14 operates, and the areca nuts on top of the telescopic partition 13 fall through the bottom of the conical trough 11 into the corresponding receiving box 15. The fresh areca nuts are quickly frozen inside the screening chamber 3, achieving simultaneous sorting and quick-freezing of fresh areca nuts. This reduces the quick-freezing process, avoids prolonged contact between the areca nuts and the outside environment during sorting, and ensures long-term preservation of the areca nuts.

[0020] In summary, this effectively solves the problem that existing quick-freezing and preservation devices require sorting betel nuts according to their size before quick-freezing, which is a lengthy process and prone to contamination during sorting, affecting the long-term preservation of fresh betel nuts.
