Abstract
Description
Technical Field
[0001] This invention relates to the field of fruit and vegetable food processing. More specifically, this invention relates to a self-freezing fruit granule anti-sticking sorting device and its method of use. Background Technology
[0002] Grapes, blueberries, and green almonds are popular fruits rich in vitamins, minerals, and antioxidants, which are beneficial to human health. However, these fruits have a short shelf life and are prone to spoilage after harvesting, which limits their sales scope and time. Taking green almonds as an example, green almonds have a crisp texture, are juicy, and have a unique sweet and astringent flavor. They are rich in vitamins, polyphenols, and dietary fiber. They can be eaten fresh or used to make preserves, canned goods, juices, or wine. However, the outer green skin of green almonds is very delicate. Even slight collisions, squeezing, or friction during harvesting and post-harvest processing can easily damage the skin. Once the skin is broken, the flesh will quickly oxidize and turn brown. The seepage of juice not only causes the loss of flavor substances but also provides conditions for the growth of microorganisms, leading to spoilage. The shelf life is extremely short, usually only a few hours to a day. Cold chain preservation measures are necessary for commercial distribution.
[0003] Currently, common methods for preserving fruits include refrigeration and freezing. While refrigeration can extend the shelf life of fruits to some extent, the effect is limited. Moreover, the taste and nutritional content of the fruit will gradually decline over time. Traditional quick-freezing methods have certain problems when quick-freezing fruit. The most critical issue is that after quick-freezing a whole box of fruit, the fruit pieces tend to stick together and become compacted. Forcibly separating the sticky fruit pieces will inevitably damage the peel or flesh, requiring proper thawing first, which affects subsequent handling and processing.
[0004] Currently, to prevent fruit from sticking and caking during quick-freezing, mesh sorting trays are generally used. Taking the sorting of frozen green almonds as an example, the mechanical collisions and friction generated by traditional vibrating or drum sorting machines during operation can easily cause the almond skin to crack and the flesh to be damaged. This not only affects the appearance but also causes juice loss and rapid oxidation and browning, greatly shortening the shelf life and reducing the commercial value. Manual sorting is labor-intensive, inefficient, and the results are not ideal. Therefore, a new sorting device is needed that can save labor and avoid damage to the fruit during the sorting process. Summary of the Invention
[0005] One objective of this invention is to provide a quick-frozen fruit sorting device and method for preventing sticking, which can save labor and avoid damage to the fruit during the sorting process.

One end of a sling is fixed on the lifting support, and the other end of the sling is connected to the lifting mechanism.
[0009] Preferably, a bristle-type blocking mechanism is provided in the through groove. The bristle-type blocking mechanism is a bristle group provided on one or both sides of the inner wall of the through groove. One end of the bristle group is fixed to the inner wall of the through groove and the other end is a free end, so that the connecting beam can move up and down in the through groove while blocking the fruit particles from passing through.
[0010] Preferably, the lifting supports on the stacked annular arrays are staggered, and each lifting support corresponds to a through slot.
[0011] Preferably, the lifting mechanism consists of several through-type screw motors fixed to the upper part of the cylinder and positioned corresponding to the lifting supports. A screw is vertically inserted through the middle of each through-type screw motor. A hook is rotatably provided at the upper end of the sling, and a lifting ring is rotatably provided at the lower end of the screw. Several hooks are hung on the lifting rings.
[0012] Preferably, the lifting support has at least one vertically opening limit hole, and a limit post is inserted into each limit hole. The limit post is set in the annular space and its bottom is fixed to the cylinder body. A support block is provided on the post body of the limit post. The size of the support block is larger than the size of the limit hole. When the annular aligning tray is in the unlifted state, the annular aligning tray is supported by the support block.
[0013] Preferably, the annular alignment plate includes an inner annular beam and an outer annular beam.

[0024] like Figures 1-17As shown, the present invention provides a quick-frozen fruit granule anti-sticking sorting device, comprising: a cylinder 1, wherein an isolation cover 4 is coaxially mounted inside the cylinder 1, the isolation cover 4 having a cylindrical structure, the top of the isolation cover 4 being lower than the liquid level line in the cylinder 1; and a plurality of annular sorting trays 2 stacked below the liquid level line in the cylinder 1, the annular sorting trays 2 having an inverted conical ring structure, wherein the annular sorting trays 2 have a central through hole 200 for coaxially fitting around the outside of the isolation cover 4. The inner ring edge of the aligning disc 2 is flush with the outer wall of the isolation cover 4, and the outer ring edge of the aligning disc 2 is flush with the inner wall of the cylinder 1. The inner ring edge of the aligning disc 2 is lower than the outer ring edge. The disc body of the aligning disc 2 is recessed in a matrix to form several receiving compartments 260. Each receiving compartment 260 can only hold one fruit 8. The receiving compartments 260 are permeable to water from top to bottom. A lifting mechanism is set on the cylinder 1 to lift the aligning discs 2 out of the cylinder 1 one by one from top to bottom.
[0025] In this technical solution, the annular aligning disc 2 is made of hard materials such as metal or plastic. The receiving compartment 260 is a recessed cavity obtained by metal stamping or plastic injection molding. The receiving compartment 260 can be circular, elliptical, or hexagonal. Each receiving compartment 260 is configured to be permeable from top to bottom by openings or other means. The annular aligning disc 2 is inverted conical. Fruit particles 8 that do not enter the receiving compartment 260 can slide or roll off the surface of the annular aligning disc 2 under their own weight and return to the inside of the cylinder 1 through the central through hole 200. The inner and outer ring edges of the annular aligning disc 2 are respectively aligned with the outer wall of the isolation cover 4 and the cylinder. The inner wall of the cylinder 1 prevents fruit pieces 8 from falling directly onto the next layer of the annular aligning tray 2. The isolation cover 4 is a water-permeable or non-water-permeable structure made of rigid material. The top of the isolation cover 4 is below the liquid level line, so that fruit pieces 8 rolling off the annular aligning tray 2 that has been removed from the cylinder 1 do not directly contact the isolation cover 4, thus avoiding damage to the fruit peel and pulp. The edge of the annular aligning tray 2 can be equipped with lifting lugs or other structures for attaching a traction rope. Since there is no direct stirring mechanism inside the cylinder 1, the traction rope can be manually lowered into the water and attached to the annular aligning tray 2. The lifting mechanism can be a mechanical hook set on the upper part of the cylinder 1, or it can be manually pulled.
[0026] In this technical solution, the annular aligning trays 2 are first stacked downwards inside the tank 1. Water is poured into the tank 1, followed by fruit pieces 8. The fruit pieces 8 can be single fruits such as blueberries, raspberries, grapes, and almonds. Ideally, the fruit pieces 8 float on the water surface. When dealing with fruit pieces 8 that have a density greater than water, a salt solution can be poured into the tank 1. As the top annular aligning tray 2 is pulled upwards out of the tank 1, the fruit pieces 8 fill the receiving compartments 260 on the annular aligning tray 2. At this time, the inner ring edge of the annular aligning tray 2 is flush with the outer wall of the isolation shield 4. Fruit pieces 8 that have not entered the receiving compartments 260 will not fall. Furthermore, because the inner ring edge of the annular aligning tray 2 is flush with the isolation shield 4, the fruit pieces 8 remain in contact with the outer wall of the isolation shield 4. In water, there will be no significant friction or crushing of the fruit pieces 8. After the inner ring edge of the annular sorting disc 2 passes the top of the isolation cover 4, the central through hole 200 is no longer blocked. Fruit pieces 8 that have not entered the receiving compartment 260 will slide or roll off the annular sorting disc 2 under their own weight. Even if the annular sorting disc 2 has been completely pulled out of the water, the fruit pieces 8 will enter the water first, and the falling process will not cause significant impact on the peel and pulp. This device uses the inclined annular sorting disc 2 to sort the fruit pieces 8 in water, avoiding the collision of fruit pieces 8 during conventional vibration sorting and conveying, greatly reducing the probability of damage to the peel and pulp, and has a high degree of automation, which greatly reduces the workload of manual sorting of fruit pieces 8.
[0027] For example, when sorting unripe almonds, the size and shape of the receiving compartment 260 are first designed according to the diameter range of the fruit, ensuring that each compartment can hold only one unripe almond, while avoiding squeezing the peel due to insufficient spacing. The edges of the receiving compartment 260 should be sufficiently rounded or covered with a food-grade flexible coating to further prevent scratching the peel. Given that unripe almonds are soft and easily exude juice, clean cold water or a small amount of food-grade vitamin C color-protecting solution can be added to the tank 1. This not only provides buoyancy but also delays the oxidation and discoloration of the unripe almonds to some extent during the sorting process. The temperature of the solution can be cooled according to process requirements. To inhibit microbial activity and maintain the freshness of green almonds, after the green almonds are poured into the tank 1, a gentle swirling motion is created by low-speed stirring to evenly disperse the almonds 8. Vigorous stirring is avoided to prevent the almonds 8 from colliding with each other or rubbing against the isolation cover 4. When the lifting mechanism lifts the annular sorting tray 2 filled with green almonds, it should maintain a stable and low-speed operation to avoid sudden starts, stops, or shaking that could cause the almonds 8 to shake or splash out of the receiving compartment 260. The sorted green almonds, along with the sorting tray 26, can be transferred to the quick-freezing production line or pre-cooling room after the surface moisture is drained, achieving a seamless connection from sorting to preservation and minimizing the impact of intermediate processing on product quality.
[0028] In another technical solution, the isolation cover 4 is a rigid mesh structure. A stirring shaft 51 is coaxially arranged inside the isolation cover 4. The shaft of the stirring shaft 51 is equipped with several stirring blades 5. The bottom end of the stirring shaft 51 extends out of the cylinder 1 and is connected to a stirring motor 52. In this technical solution, the isolation cover 4 can be made of wire mesh. The mesh size of the isolation cover 4 is much smaller than the size of the fruit particles 8, which can effectively block the fruit particles 8 without affecting the water exchange inside and outside the isolation cover 4. The stirring shaft 51... The bottom of the cylinder 1 is watertight to prevent leakage. The stirring blade 5 is a vertical plate circumferentially set on the stirring shaft 51 and is used to create a vortex inside the isolation cover 4. In this technical solution, in order to solve the problem that when the fluid in the cylinder 1 is still, the fruit particles 8 tend to accumulate at the bottom of the annular aligning plate 2 under the action of gravity, so that the receiving compartment 260 at the top of the annular aligning plate 2 does not contain fruit particles 8, the stirring blade 5 is used to create a vortex with an appropriate flow rate in the cylinder 1 so that the fruit particles 8 can be better and more evenly distributed in the annular aligning plate 2.
[0029] In another technical solution, the cylinder body 1 includes an outer cylinder wall 11 and an inner cylinder wall 12, forming an annular space 100 between the outer cylinder wall 11 and the inner cylinder wall 12. The inner cylinder wall 12 has several vertical through slots 120 evenly spaced along its surface. The outer edge of the annular alignment plate 2 is flush with the inner wall of the inner cylinder wall 12. Each annular alignment plate 2 has at least three lifting supports 25, which are located within the annular space 100 and connected to the annular alignment plate 2 via connecting beams 24 passing through the through slots 120. One end of a lifting cable 3 is fixed to each lifting support 25, and the other end of the lifting cable 3 is connected to the lifting mechanism. In this technical solution, the cylinder body 1 has a double-layer structure, wherein the inner cylinder wall 11... The cylinder 2 has several vertical slots 120, the width of which is smaller than the size of the fruit 8. The lifting support 25 is connected to the outside of the annular array plate 2 by a connecting beam 24, and the width of the connecting beam 24 is adapted to the width of the slot 120. The lifting support 25 is anchored with a sling 3, the other end of which extends out of the cylinder 1. In this technical solution, the stacked annular array plates 2 can share a set of slots 120. Since the sling 3 is flexible, the sling 3 on the first annular array plate 2 does not affect the sling 3 on the later annular array plate 2. In the process of lifting the annular array plate 2 out of the water from top to bottom, only the corresponding sling 3 needs to be selected, and no structural conflict will be caused.
[0030] In another technical solution, a bristle-type blocking mechanism 13 is provided in the through groove 120. It is a bristle group set on one or both sides of the inner wall of the through groove 120. One end of the bristle in the bristle group is fixed to the inner wall of the through groove 120 and the other end is a free end, so that the connecting beam 24 can move up and down in the through groove 120 while blocking the fruit 8 from passing through. In this technical solution, in order to prevent the fruit 8 from passing through the through groove 120 when the through groove 120 is wide, a bristle-type blocking mechanism 13 is added in the through groove 120. The bristles can be made of food-grade nylon material, which has a certain resistance to deformation. The dense bristles can effectively block the fruit 8, while not hindering the up and down movement of the connecting beam 24.
[0031] In another technical solution, the lifting supports 25 on several stacked annular alignment trays 2 are staggered, and each lifting support 25 corresponds to a through slot 120. In this technical solution, the stacked annular alignment trays 2 are rotated appropriately to stagger the positions of the lifting supports 25. Figure 1 As shown, four annular alignment trays 2 are stacked, with three lifting supports 25 set on the outer edge of each annular alignment tray 2. The lifting supports 25 on the same annular alignment tray 2 are spaced 120° apart. The annular alignment tray 2 rotates around the central axis from top to bottom by 0°, 30°, 60° and 90°, staggering the lifting supports 25 between the annular alignment trays 2. Each through slot 120 corresponds to only one lifting support 25, which facilitates the distribution of the slings 3 and makes it easier for the subsequent lifting mechanism to lift.
[0032] In another technical solution, the lifting mechanism consists of several through-type lead screw motors 7 fixed to the upper part of the cylinder body 1 and positioned corresponding to the lifting supports 25. A lead screw 71 is vertically inserted through the middle of each through-type lead screw motor 7. A hook 31 is rotatably mounted on the upper end of the sling 3, and a lifting ring 73 is rotatably mounted on the lower end of the lead screw 71. The hook 31 is hung on the lifting ring 73. In this technical solution, a bracket consisting of several columns 6 and crossbeams 61 is also provided outside the cylinder body 1. Motor supports 62 are provided on the crossbeams 61 for mounting the through-type lead screw motors 7. The columns 6, crossbeams 61, and motor supports 62 can all be made of profile steel, and holes are drilled at corresponding positions to allow the lead screw 71 to pass through. The through-type lead screw motors 7 are bolted to... On the crossbeam 61 or motor support 62, the through-type lead screw motor 7 is located directly above the lifting support 25. The through-type lead screw 71 can rotate upward or downward under the action of the gear set in the through-type lead screw motor 7. The through-type lead screw motor 7 is a ready-made component that is readily available in the market. In this technical solution, optionally, the top end of the sling 3 can be provided with a first bearing body 310. The end of the sling 3 is fixed to the inner bearing of the first bearing body 310, and the hook 31 is fixed to the outer bearing of the first bearing body 310. The bottom end of the lead screw 71 can be provided with a second bearing body 72. The inner bearing of the second bearing body 72 is connected to the lead screw 71, and the outer bearing is connected to the lifting ring 73. The hook 31 is suspended on the lifting ring 73. The rotation of the lead screw 71 when it rises or falls does not affect the sling 3.
[0033] In this technical solution, such as Figure 16 As shown, each annular alignment disc 2 corresponds to a set of through-type lead screw motors 7. When a set of through-type lead screw motors 7 lifts synchronously, the annular alignment disc 2 is vertically pulled out of the cylinder 1. Then, if one of the through-type lead screw motors 7 controls the corresponding lead screw 71 to rise, the annular alignment disc 2 can tilt because the sling 3 is flexible. By controlling the sling 3 to rise or fall sequentially through a set of through-type lead screw motors 7, the annular alignment disc 2 can rotate and sway above the cylinder 1, shaking the fruit pieces 8 that have not entered the receiving compartment 260 into the central through hole 200.
[0034] In another technical solution, the lifting support 25 has at least one vertically opening limiting hole 250, and a limiting post 14 passes through each limiting hole 250. The limiting post 14 is located within the annular space 100 and its bottom is fixed to the cylinder body 1. A support block 15 is provided on the post body of the limiting post 14. The size of the support block 15 is larger than the limiting hole 250. When the annular alignment plate 2 is in an unlifted state, the annular alignment plate 2 is supported by the support block 15. In this technical solution, in order to avoid the through-type lead screw motor 7 being continuously stressed in the non-lifting state, a support structure is required to support the annular alignment plate 2, such as... Figure 7 As shown, the lifting support 25 has two limiting holes 250 on its plate. Two limiting posts 14, whose bottoms are fixed to the cylinder 1, are matched and inserted into the limiting holes 250. Support blocks 15 protrude from the limiting posts 14. When lowering the annular aligning tray 2, the limiting holes 250 are aligned with the limiting posts 14 and then lowered until the annular aligning tray 2 contacts the support blocks 15. The height of the support blocks 15 corresponding to each annular aligning tray 2 is different.
[0035] In another technical solution, the annular alignment plate 2 includes an inner annular beam 21 and an outer annular beam 23. A plurality of support beams 22 are radially and equally spaced between the inner annular beam 21 and the outer annular beam 23. An alignment plate 26 is installed between any two adjacent support beams 22. The alignment plate 26 includes a plate body 261, the size of which matches the fan-shaped area enclosed by the inner annular beam 21, the outer annular beam 23, and the two adjacent support beams 22. The plate body 261 is recessed in a matrix to form a plurality of receiving compartments 2. 60. Supporting vertical plates 262 extend downward from both sides of the plate 261. Several fixing grooves 263 are recessed on the bottom edge of the supporting vertical plates 262. Outer columns 221 extend horizontally from both sides of the supporting beam 22 corresponding to the fixing grooves 263. The fixing grooves 263 are correspondingly placed and engaged with the outer columns 221. In this technical solution, to facilitate manual transfer of the sorted fruit pieces 8 without replacing the entire annular sorting tray 2, the annular sorting tray 2 is designed to be detachable. For example... Figures 9-14 As shown, the annular alignment tray 2 consists of an inner annular beam 21, an outer annular beam 23, and several radially arranged support beams 22 forming a fixed frame. The alignment plate 26 is detachably connected to this frame and is placed directly between the support beams 22 on both sides via support vertical plates 262. Figure 11 As shown, the alignment plate 26 has a trapezoidal structure. The gap between the alignment plate 26 and the inner ring beam 21 and the outer ring beam 23 is sealed by the sealing plate 27. After the annular alignment plate 2 is lifted out of the cylinder 1 as a whole, the operator can directly remove the alignment plate 26. After all the alignment plates 26 on the annular alignment plate 2 have been removed, the operator can replace them with new alignment plates 26.
[0036] In another technical solution, the receiving compartment 260 includes a plate hole 2600 formed on the plate 261. The edge of the plate hole 2600 extends downward to form a transition cylinder 2601. The bottom edge of the transition cylinder 2601 is connected to a support frame 2602 composed of several rigid thin rods. In this technical solution, the edges of the transition cylinder 2601 and the plate hole 2600 are chamfered to avoid forming sharp edges. Alternatively, a flexible material can be covered at the edge of the receiving compartment 260. For example, the entire plate 26 is a metal plate. To facilitate the processing of the entire plate 26, a pre-set hole of appropriate size is first opened on the surface of the plate 261. Then, a mechanical stamping process is used to process the pre-set hole on the plate 261 to form the plate hole 2600. During the pressing process, the plate around the pre-set hole is pulled down to form the transition cylinder 2601. The support frame 2602 is fixed below the transition cylinder 2601 by laser spot welding. Figure 14 As shown, the 260 compartment is designed as a hexagon, which allows the oval-shaped almond kernels to enter more quickly.
[0037] In another technical solution, the method of using the quick-frozen fruit granule anti-sticking sorting device is applied to the above-mentioned quick-frozen fruit granule anti-sticking sorting device, characterized by including the following steps; S1. Pass the annular aligning trays 2 one by one through the isolation cover 4 and lower them into the cylinder 1. Each annular aligning tray 2 is connected to the lifting mechanism by a rope. For example, the operator fixes the lower end of the sling 3 to the lifting support 25 and installs the hook 31 on the upper end. The annular aligning trays 2 are lowered layer by layer along the axis of the cylinder 1. Before lowering each layer of annular aligning trays 2, the angle needs to be adjusted so that the position of the lifting support 25 is staggered from the previous layer and that the limiting hole 250 of each lifting support 25 is aligned with the corresponding limiting post 14. Lower the annular aligning trays 2 until their bottom contacts the support block 15 on the limiting post 14. After all the annular aligning trays 2 have been lowered, hook the hook 31 onto the corresponding lifting ring 73.
[0038] S2. Pour water or salt solution into cylinder 1 up to the liquid level line, so that the liquid level is simultaneously higher than the top of the isolation shield 4 and the outer edge of the uppermost annular arrangement plate 2. Pour in fruit granules 8. For example, according to the density of fruit granules 8, pour water or salt solution into cylinder 1 until the liquid level simultaneously exceeds the top of the isolation shield 4 and the outer edge of the uppermost annular arrangement plate 2. Start the stirring motor 52 to drive the stirring shaft 51 to rotate, causing the stirring blades 5 in the isolation shield 4 to generate swirling flow. Pour in an appropriate amount of fruit granules 8. The number of fruit granules 8 should not exceed 98% of the total number of containers 260. The fruit granules 8 are dispersed under the buoyancy of the solution and the swirling flow to avoid accumulation.
[0039] S3. The lifting mechanism vertically lifts the top ring-shaped aligning tray 2 out of the cylinder 1 and above the isolation cover 4. Some of the fruit pieces 8 inside the cylinder 1 are matched one by one and enter the receiving compartment 260. The rest roll back into the cylinder 1 through the central through hole 200. The ring-shaped aligning tray 2 filled with fruit pieces 8 is transferred to the next process. For example, the lifting mechanism starts a set of through-type screw motors 7 corresponding to the top ring-shaped aligning tray 2 to lift the top ring-shaped aligning tray 2 out of the cylinder 1. The set of through-type screw motors 7 controls the shaking of the ring-shaped aligning tray 2, so that all the fruit pieces 8 that have not entered the receiving compartment 260 fall back into the cylinder 1. The aligning plate 26 is manually removed, and the remaining part of the ring-shaped aligning tray 2 is kept in the lifting state. After the aligning plate 26 is removed, the surface moisture is drained and it enters the quick-freezing stage.
[0040] S4. Repeat step S3 until all annular alignment plates 2 or all fruit pieces 8 are removed from cylinder 1. For example, before each lifting, it is necessary to switch to a set of through-type lead screw motors 7 of the corresponding annular alignment plate 2. If the filling rate of the compartment 260 on the bottom annular alignment plate 2 is too low, it can be manually removed. After all the alignment plates 26 are removed, a new alignment plate 26 is reinstalled, and steps S1 to S4 are repeated.
[0041] In this technical solution, water or salt solution injected into the cylinder 1 provides a buoyancy buffer environment. Combined with the inclined structure of the inverted conical annular sorting tray 2 and the matrix-style receiving grid 260 design, the fruit pieces 8 naturally slide into the single-fruit-limiting receiving grid 260 underwater. Unmatched fruit pieces 8 roll down along the tray surface through the central through hole 200 back below the liquid surface, without any hard collisions. The lifting mechanism precisely controls the vertical lifting and swaying of the annular sorting tray 2 through the through-type screw motor 7. With the help of the detachable sorting plate 26, the sorting and quick-freezing processes are efficiently connected, significantly reducing the fruit peel damage rate and greatly reducing manual intervention.
[0042] It should be noted that although the steps are described in a specific order above, this does not mean that they must be performed in that order. In fact, some of these steps can be executed concurrently, or even in a different order, as long as the required functionality is achieved.
