Description

Technical Field

[0001] This invention belongs to the field of fruit peeling and processing equipment, specifically relating to a peeling, seed extraction and separation device suitable for wrinkled pomegranates. Background Technology

[0002] Pomegranate, a plant belonging to the genus Punica granatum in the family Punicaceae, is an excellent fruit tree that combines ecological, economic, social, ornamental, and health benefits. The fruit contains various amino acids, proteins, abundant carbohydrates, minerals, vitamins, and trace elements. Vitamin C and carotene in pomegranates can prevent cell carcinogenesis and atherosclerosis. The pomegranate peel contains pomegranate peel alkaloids, which can anesthetize parasites in the human body, thus having an astringent and antidiarrheal effect. Red pomegranate polyphenols and anthocyanins can resist inflammation and the damaging effects of oxygen free radicals, thereby delaying aging and preventing cardiovascular diseases. It also contains linoleic acid, vitamins C and B6, which can help lower blood sugar, promote detoxification and bowel movements, and make the skin brighter. In 2019, the national pomegranate production reached 1 million tons. Pomegranates are loved by many, but the pomegranate fruit inside the peel is not easy to remove. Initially, people used manual labor to extract pomegranate seeds. Each person could only peel one pomegranate at a time, which was time-consuming and inefficient. Therefore, a pomegranate peeling and seed extraction device was developed to replace manual labor.

[0003] Currently, pomegranate peeling and seed extraction machinery in my country mainly uses crushing and extrusion methods and mechanical beating. The crushing and extrusion method involves directly crushing the whole pomegranate into pieces under significant pressure, resulting in a high seed breakage rate. Furthermore, the calyx contains numerous impurities and bacteria, and the seeds are already contaminated. Subsequent separation devices lack adjustable gaps, leading to incomplete separation of peel and seeds. The mechanical beating method is slow because the pomegranate needs a frame for support during beating, which helps prevent seeds from falling out. However, the frame also hinders seed release, making it difficult to remove seeds from the peel, resulting in a low separation rate. Research on existing pomegranate peeling methods has found that removing the calyx is a crucial step affecting seed extraction efficiency. After removing the calyx, the pomegranate peel's integrity decreases, making the pomegranate easier to break open. Impurities and bacteria within the calyx do not come into contact with the seeds, ensuring their hygiene and safety. The thickness of pomegranate peel ranges from 1.5mm to 3mm. For pomegranates with the calyx removed, pre-treating the peel by scoring the surface can significantly improve the success rate of opening the pomegranate and increasing the seed extraction rate. Research on existing pomegranate seed extraction devices reveals that there is no mechanism to adjust the kneading and squeezing gap during the opening process. This may lead to uneven opening of the pomegranate, affecting subsequent seed extraction efficiency. Current pomegranate seed extraction devices use a crushing and squeezing method that directly breaks the whole pomegranate into pieces, lacking a mechanism for removing the calyx and pre-treating the surface by scoring, resulting in a high seed breakage rate. A search for solutions to these problems yielded no relevant technical solutions. Summary of the Invention

The pomegranates entering through the feed inlet 3 fall onto the pomegranate fixing seat 4. After the pomegranates are crushed and pretreated by the calyx removal unit 5 and the petal separation unit 6, they enter the seed extraction unit.

[0031] The seed-collecting unit 18 includes a roller 9, a seed-distributing wheel 10, an adjustable-gap screen unit 16, a rotating shaft unit, and a circular-hole screen 12. The roller 9 is located to the lower right of the discharge end of the conveyor belt 2. The adjustable-gap screen unit 16 is located below the roller 9. The bottom of the roller 9 and the adjustable-gap screen unit 16 form a first concave space. The discharge end of the first concave space is connected to the seed-distributing wheel 10. The seed-distributing wheel 10 is located at the rear end of the roller 9. The seed-distributing wheel 10 and the adjustable-gap screen unit 16 form a second concave space. The discharge end of the second concave space is connected to a connecting channel 11 that communicates with the feed end of the rotating shaft unit. The rotating shaft unit includes two... A rotating shaft 13 is arranged in parallel. The end of the rotating shaft 13 is connected to a conveyor motor 131 via a connecting shaft 132. A striking block 14 is evenly distributed and spaced on the rotating shaft 13. The striking blocks 14 on the two rotating shafts 13 mesh with each other. The other end of the rotating shaft 13 is provided with a discharge trough 133 and a pomegranate peel discharge port 134. A circular hole screen 12 is provided outside the rotating shaft unit. A pomegranate seed collection auxiliary channel 17 is provided below the adjustable spacing screen unit 16. The pomegranate seed collection auxiliary channel 17 is connected to the pomegranate seed collection port 15. The discharge end of the circular hole screen 12 is connected to the pomegranate peel discharge port 134 and the pomegranate seed collection port 15 respectively.

[0032] The calyx removal unit 5 includes a lead screw motor 51, a frame 52, an annular calyx removal cutter 53, and a calyx removal positioning ring 54. The lead screw motor 51 is mounted on the frame 52, and the lower end of the lead screw motor 51 is connected to the annular calyx removal cutter 53. The lower end of the annular calyx removal cutter 53 is provided with a calyx removal positioning ring 54.

[0033] The splitting unit 6 includes a linear cylinder 61, a cylinder bracket 62, a linear spring 63, a mounting block 64, a frame connecting rod 65, a bottom plate 66, a blade connecting rod 67, and a blade 68. The linear cylinder 61 is mounted on the cylinder bracket 62. The lower end of the cylinder bracket 62 is connected to the mounting block 64 through the linear spring 63. The two ends of the mounting block 64 are respectively hinged to the frame connecting rod 65. The end of the frame connecting rod 65 is hinged to the blade connecting rod 67. The ends of the blade connecting rod 67 are all connected to the blade 68. The bottom plate 66 is hinged between the blade connecting rods 67.

[0034] The adjustable-gap screen unit 16 includes a seed-collecting unit inlet 161, a fixed rotating shaft 162, a screen 163, an eccentric wheel 164, and a stepper motor 165. The left end of the screen 163 is connected to the fixed rotating shaft 162, and the right end of the screen 163 is connected to the stepper motor 165. The stepper motor 165 is connected to the eccentric wheel 164, which supports the screen 163. The stepper motor 165 drives the eccentric wheel 164 to move and adjust the size of the first concave space and the second concave space.

[0035] The surface of the roller 9 is provided with several concave arc pits, which are designed to allow the pomegranates that enter the bottom of the roller and form a concave space with the adjustable spacing screen to be subjected to a combined force of squeezing and reciprocating kneading, so as to crush them more thoroughly.

[0036] The concave arc pit surface is covered with an elastic rubber layer, and the seed-reeling wheel 10 surface is also covered with an elastic rubber layer. This is to prevent damage to the pomegranate seeds when they are subjected to a combined force of squeezing and reciprocating kneading as they enter the rolling cylinder 9 and the seed-reeling wheel 10.

[0037] The circular mesh 12 has circular holes with a diameter of 8mm, which is to allow the unfolded pomegranate seeds to fall quickly from the mesh into the pomegranate seed collection port 15 under the sieving of the sieve cylinder.

[0038] The striking blocks 14 on the two rotating shafts 13 are distributed in a curved meshing pattern, which can further crush the pomegranate fruit to improve the subsequent separation efficiency and separation effect.

[0039] The diameter of the annular calyx-removing cutter 53 is 20-25 mm to avoid incomplete calyx removal, which would affect the crushing of the pomegranate.

[0040] The working principle of this invention is as follows:

[0041] Cleaned pomegranates are placed on pomegranate holders 4 with the calyxes facing upwards. They are then conveyed to the crushing pre-treatment unit 8 via conveyor belt 2. With the assistance of an auxiliary positioning camera 7, the pomegranates are transported to the working range of the calyx removal unit 5. Under the same guidance, the annular calyx removal cutter 53 is positioned above the pomegranate calyx. When the screw motor 51 starts, it drives the toothed annular calyx removal cutter 53 and the calyx removal positioning ring 54 to rotate downwards. When the calyx removal positioning ring 54 reaches the pomegranate calyx, it supports the pomegranate against the pomegranate holder 4. Because the calyx removal positioning ring is in contact with the pomegranate, it cannot move. The screw motor 51 continues to rotate, and through the threaded connection at the end of the calyx removal positioning ring 54, the annular calyx removal cutter 53 continues to rotate downwards and cut. When the toothed annular calyx removal cutter 53 contacts the pomegranate calyx, it... Under the control of the screw motor 51, the pomegranate undergoes a rotary cutting motion, penetrating to a certain depth. Under the combined action of cutting force and rotational force, the pomegranate calyx is squeezed into the hollow middle part of the annular calyx-removing cutter 53. At this time, the screw motor 51 reverses, driving the annular calyx-removing cutter 53 and the calyx-removing positioning ring 54, which have already had their calyx removed, to move upward. Because there is a protruding platform at the lower end of the calyx-removing support, the calyx-removing positioning ring 54 cannot continue to move upward after contacting it. The screw motor 51, through a threaded connection, causes the annular calyx-removing cutter 53 to continue moving upward, resetting the calyx-removing unit 5 and removing the calyx. The removed calyx is still in the annular calyx-removing cutter 53. When the next pomegranate undergoes the calyx-removing process, the calyx of the next pomegranate will push off the calyx inside the annular cutter. The calyx falls out of the calyx discharge port through the calyx collection channel below the roller chain. The pomegranate with its calyx removed continues to be conveyed by the conveyor belt to the working range of the petal-splitting unit.

[0042] With the positioning assistance of the auxiliary positioning camera 7, the pomegranate with its sepals removed is positioned above the petal-splitting unit 6. When the linear cylinder 61 motor starts, it drives the frame connecting rod 65 and the blade connecting rod 67 to move downward in a straight line. When the blade 68 contacts the pomegranate peel and continues to move downward, the blade 68 generates resistance due to contact with the pomegranate peel. The end of the blade connecting rod 67 connected to the blade moves outward under the stress of the pomegranate peel, causing the end of the blade connecting rod 67 to move inward. The end of the blade connecting rod 67 is connected to the frame connecting rod. When the end of the blade connecting rod moves inward, it drives the frame connecting rod to move upward. The bottom plate 66 is connected to the upper end of the frame connecting rod. Because the connecting rod is non-extendable, the frame connecting rod continues to move upward, causing the bottom plate 66 to move upward and compress the linear spring 63. The linear spring 63 begins to be stressed and compressed. When the blade 68 passes the maximum diameter of the pomegranate, the force on the linear spring 63 decreases and it begins to recover its stretch, causing the bottom plate 66 to move downward. When the bottom plate 66 moves downward, it drives the frame connecting rod downward, causing the connection between the blade connecting rod 67 and the frame connecting rod 65 to move outward, so that the blade 68 continues to contact the pomegranate skin and continue to cut the skin. When the linear cylinder 61 motor resets, it drives the entire segmentation unit to reset, and the pomegranate completes the skin-breaking and segmentation process.

[0043] Pomegranates with their sepals removed and petals scored are conveyed to roller 9 by a conveyor belt. The roller and the adjustable-gap screen unit 16 form a large-gap concave space, while the seed-picking wheel 10 and the adjustable-gap screen unit 16 form a small-gap concave space. During the seed-picking process, the pomegranates first enter roller 9. Squeezed by the rollers, the pomegranates with their sepals removed are squeezed open along the four scratches on their skin, revealing the seeds. After being kneaded by the rollers, the pomegranates are initially opened, and the seeds fall onto the adjustable-gap screen unit. The adjustable-gap screen unit 16 consists of a seed-picking unit inlet 161, a fixed rotating shaft 162, a screen 163, an eccentric wheel 164, and a stepper motor 165. The left end of the screen 163 is connected to the fixed rotating shaft 162. The feed inlet 161 of the seed-collecting unit is connected, and the right end of the screen 163 is connected to the stepper motor 165. The stepper motor 165 is connected to the eccentric wheel 164, which supports the screen 163. The stepper motor 165 drives the eccentric wheel 164 to move and adjust the size of the first concave space and the second concave space. Due to the change in the support point of the eccentric wheel 164, the concave space formed by the roller 9, the seed-picking wheel 10, and the adjustable-gap screen unit changes from large to small. The pomegranate seeds are more likely to fall out of the screen holes through the adjustable-gap screen. The opened pomegranate is crushed into pomegranate seeds and unfolded pomegranate by the squeezing and repetitive kneading of the roller and the seed-picking wheel. At this time, most of the pomegranate seeds in the center of the pomegranate have been separated, and some pomegranate seeds that are not easy to knead out are near the inside of the pomegranate peel. The unfolded pomegranate is approximately two-dimensional. The unfolded pomegranate is pushed to the feed end of the rotating shaft by the seed-dispensing wheel. The pomegranate seeds fall from the adjustable-gap screen and the circular hole screen, pass through the auxiliary pomegranate trough, and reach the pomegranate seed outlet. The unfolded pomegranate is broken into pomegranate pieces of different sizes by the meshing and impact of the rotating shaft, so that the pomegranate seeds near the inner side of the pomegranate peel are exposed. The unfolded pomegranate is completely decomposed into pomegranate peel and pomegranate seeds under high-speed rotation. The pomegranate seeds are separated from the circular hole screen and collected through the pomegranate seed collection port 15. The pomegranate residue and pomegranate peel are pushed to the discharge trough 133 by the rotating shaft and enter the pomegranate peel discharge port 134 for collection.
