Abstract
Description
Technical Field
[0001] This utility model relates to the field of fruit processing technology, and in particular to a device for preliminary separation of fruit pulp and pit. Background Technology
[0002] As a traditional Chinese medicine, jujube seed has the effects of nourishing the liver, calming the mind, soothing the nerves, and astringing sweat. It can be used to treat neurasthenia, insomnia, dreaminess, and night sweats. Jujube seed is wrapped in the kernel. In order to obtain jujube seed, the pulp and kernel need to be separated first so that the kernel can be further shelled and screened.
[0003] Existing technologies typically use direct friction cutting to separate jujube pulp from jujube pits. However, due to the high viscosity of the pulp, it is easy for the pulp to be carried into the pit, affecting the separation effect. If the pulp is washed away by friction cutting and water rinsing, the pulp will lose nutrients and be wasted. Even if the pulp is subsequently collected and dried, it will increase energy consumption.
[0004] Therefore, it is necessary to propose a preliminary separation device for fruit pulp and seeds to overcome the shortcomings of existing technologies. Utility Model Content
[0005] The purpose of this invention is to solve the problems in the prior art and provide a device for the preliminary separation of fruit pulp and seeds.
[0006] The technical solution of this utility model is:
[0007] A preliminary separation device for fruit pulp and pit includes a support, a drive unit, a roller, and a stirring shaft. The drive unit and the roller are both mounted on the support, with the drive unit located on one side of the roller. The stirring shaft is located inside the roller and is connected to the drive unit for transmission. The drive unit drives the stirring shaft to rotate relative to the roller. A stirring rod is arranged in a circumferential array on the stirring shaft, and a grinding plate and a turning plate are arranged in a circumferential array at the ends of the stirring rods. The grinding plate and the turning plate are spaced apart. Filter holes are evenly distributed on the circumferential sidewall of the roller.
[0008] Preferably, the outer cover of the roller is provided with a protective cover, which is mounted on a support. A feeding hopper is provided on the side wall of the protective cover away from the drive unit, and the feeding hopper extends through the protective cover into the inside of the roller.
[0009] Preferably, a discharge pipe is provided at the bottom of the end of the roller near the drive unit.
[0010] Preferably, the outer surface of the grinding plate facing the inner wall of the roller is arc-shaped, and a pad is provided on the arc-shaped outer surface, with the pad fitting with the inner wall of the roller with a clearance.
[0011] Preferably, the support is provided with an inclined receiving plate, which is located below the roller.
[0012] Preferably, baffles are provided on the support and on both sides of the receiving plate.
[0013] Preferably, a buffer groove is provided below the receiving plate, and the buffer groove is inclined.
[0014] Compared with the prior art, the beneficial effects of this utility model are:
[0015] This invention uses a stirring shaft to drive a turning plate to agitate and transport the material inside the roller. The gap between the grinding plate and the inner wall of the roller squeezes and kneads the fruit material, breaking it down and achieving initial separation. This facilitates the subsequent separation and extraction of the pulp and pit, improving the efficiency of pit extraction. The juice or debris produced by squeezing falls through the filter holes onto the receiving plate for unified collection and processing. The crushed fruit material is discharged to the subsequent process through the discharge pipe. Attached Figure Description

[0020] To make the technical means, technical features, utility model purpose and technical effects of this utility model easier to understand, the present utility model will be further described below with reference to specific illustrations.
[0021] like Figures 1-3As shown, a preliminary fruit pulp and pit separation device includes a support 1, a drive unit 2, a roller 5, a stirring shaft 6, and a protective cover 12. The drive unit 2 and the protective cover 12 are both mounted on top of the support 1, with the drive unit 2 located on one side of the protective cover 12. The roller 5 is installed inside the protective cover 12, allowing it to be mounted on the support 1. Since the protective cover 12 covers the outside of the roller 5, it protects the roller 5, preventing splashing during the preliminary separation of pulp and pit, thus improving hygiene. The stirring shaft 6 is installed inside the roller 5. The stirring shaft 6 is connected to the roller 5 through a bearing seat, so as to realize the rotation of the stirring shaft 6 relative to the roller 5. One end of the stirring shaft 6 extends outward through the side wall of the roller 5 and the protective cover 12 in sequence, and is connected to the drive unit 2 for transmission. In this embodiment, the drive unit 2 is a motor. The output shaft of the motor is equipped with a drive wheel 3, and a driven wheel 4 is installed at the end of the stirring shaft 6 that passes through the roller 5. A transmission belt is connected between the drive wheel 3 and the driven wheel 4. The motor drives the stirring shaft 6 to rotate through the transmission belt. The diameter of the drive wheel 3 is smaller than the diameter of the driven wheel 4 to realize the transmission of speed reduction.
[0022] A feeding hopper 13 is installed on the side wall of the protective cover 12 away from the drive unit 2. The lower end of the feeding hopper 13 extends through the protective cover 12 into the inside of the roller 5 and communicates with the inside of the roller 5. The fruit to be separated is fed into the roller 5 through the feeding hopper 13.
[0023] A stirring rod 7 is mounted on the stirring shaft 6. The stirring rods 7 are arranged in a circumferential array and distributed along the axial direction of the stirring shaft 6. A grinding plate 8 and a tilting plate 9 are mounted on the ends of the stirring rods 7 away from the stirring shaft 6. The grinding plate 8 and the tilting plate 9 are connected to each other at the ends of the stirring rods 7 in an alternating manner. The tilting plate 9 is a flat plate. The stirring shaft 6 drives the tilting plate 9 to rotate, stirring and carrying the material fed from the feeding hopper 13 to prevent it from accumulating at the bottom of the roller 5. The material can also be conveyed from one end of the roller 5 to the other by the driving action of the tilting plate 9. The outer surface of the grinding plate 8 facing the inner wall of the roller 5 is processed into an arc-shaped structure. A pad 10 is installed on the arc-shaped structure of the grinding plate 8. The pad 10 is made of soft material. The pad 10 and the inner wall of the roller 5 are in a clearance fit, or the arc of the grinding plate 8 and the inner wall of the roller 5 are concentric structures to maintain the pad. The constant gap between the grinding plate 10 and the inner wall of the roller 5, or the arc of the grinding plate 8 and the inner wall of the roller 5 having a certain inclination, so that when the grinding plate 8 rotates relative to the roller 5, the gap between the arc surface and the inner wall of the roller 5 gradually decreases. The stirring shaft 6 drives the grinding plate 8 to rotate, and the fruit material is squeezed in the gap between the pad 10 and the inner wall of the roller 5. As the grinding plate 8 rotates, it is squeezed and crushed, which facilitates subsequent separation and sorting. Filter holes 11 are evenly distributed on the circumferential side wall of the roller 5. The size of the filter holes 11 can be determined according to the size of the fruit material to be separated. When the material fed into the roller 5 is stirred and carried up during the conveying process, smaller particles, impurities in the material, juice and debris produced by squeezing can all fall to the outside of the roller 5 through the filter holes 11, avoiding affecting the separation of the fruit pit and pulp and improving the separation quality.
[0024] A discharge pipe 14 is installed at the bottom of the circumferential side wall of the roller 5 near the drive unit 2. One end of the discharge pipe 14 is connected to the inside of the roller 5, and the other end extends outward through the protective cover 12. After the crushed fruit material is stirred and conveyed to the end, it can be transferred to the outside of the roller 5 through the discharge pipe 14 for subsequent separation. The discharge pipe 14 is arranged obliquely downward from the end near the roller 5 to facilitate the material to be discharged outward by its own weight.
[0025] A receiving plate 15 is installed on the support 1, located below the roller 5. Small particles of fruit, impurities, juice, and debris falling through the filter holes 11 fall onto the receiving plate 15. The receiving plate 15 is installed at an angle. Baffles 16 are installed on the support 1 on both sides of the receiving plate 15 to seal the sides of the receiving plate 15 and prevent splashing from polluting the surrounding environment when falling. A buffer trough 17 is installed on the support 1 below the receiving plate 15. The buffer trough 17 is also installed at an angle. Items falling onto the receiving plate 15 are buffered by the buffer trough 17 when conveyed downwards, avoiding excessive drop that could cause splashing and affect collection.
[0026] The working principle of this utility model is as follows:
[0027] In use, the fruit raw materials are either manually or automatically fed into the feeding hopper 13, and then enter the roller 5 through the feeding hopper 13. The motor is started to drive the drive wheel 3 to rotate, and through the transmission belt, the driven wheel 4 and the stirring shaft 6 rotate. The turning plate 9 at the end of the stirring rod 7 turns the fruit raw materials in the roller 5 to prevent accumulation. During the turning process, the fruit raw materials are squeezed and kneaded in the gap between the pad plate 10 and the inner wall of the roller 5, which breaks the fruit raw materials. Small fruit particles, impurities, juice produced by squeezing, and small pieces of fruit pulp fall out of the filter hole 11 and are collected after passing through the receiving plate 15 and the buffer tank 17. The fruit pits that still have a small amount of fruit pulp are moved to the end of the roller 5 away from the feeding hopper 13 and discharged outside the roller 5 through the discharge pipe 14 for further separation processing.
[0028] The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of this utility model. All equivalent changes and modifications made in accordance with the scope of the claims of this utility model should fall within the technical scope of this utility model.
