Description

Technical Field

[0001] The present invention relates to the technical field of hawthorn seed and pulp separation, and particularly to a method and device for intelligent separation and extraction of hawthorn seeds and pulp. Background Art

[0002] As a characteristic fruit with both medicinal and edible properties, hawthorn is widely used in the fields of food processing, medicine and health care. In the field of food processing, due to its unique sour and sweet taste and rich pectin content, hawthorn has become the core raw material for making traditional snacks such as hawthorn cakes, fruit pastilles, and hawthorn canned food, and is deeply loved by consumers of all ages. In the beverage industry, innovative products such as hawthorn juice, hawthorn sparkling water, and hawthorn enzyme drinks have emerged continuously, conforming to the trend of healthy consumption and becoming the new favorites in the market. In the field of medicine and health care, hawthorn is rich in bioactive ingredients such as flavonoids and organic acids, and has medicinal effects such as promoting digestion, activating blood circulation and removing stasis, and reducing blood lipids. It is widely used in the research and production of traditional Chinese medicine preparations, health foods and functional beverages.

[0003] However, in terms of hawthorn seed separation, professional separation machines can be used in large-scale production, but the cost of a set of equipment is high, and small-scale workshops can hardly afford it, so manual separation is mostly adopted. Manual separation has low efficiency, and a large amount of manpower and time are required when the processing volume increases. Some workshops use simple machinery such as rolling, which can speed up the process, but there are problems such as pulp waste, high seed breakage rate, and incomplete separation. The purpose of this patent is to provide a method and device for intelligent separation and extraction of hawthorn seeds and pulp to alleviate the above-mentioned technical problems existing in the prior art. Summary of the Invention

[0004] The purpose of the present invention is to solve the problems existing in the prior art that in the aspect of hawthorn seed separation, professional separation machines can be used in large-scale production, but the cost of a set of equipment is high, and small-scale workshops can hardly afford it, so manual separation is mostly adopted. Manual separation has low efficiency, and a large amount of manpower and time are required when the processing volume increases. Some workshops use simple machinery such as rolling, which can speed up the process, but there are problems such as pulp waste, high seed breakage rate, and incomplete separation. A method and device for intelligent separation and extraction of hawthorn seeds and pulp are proposed.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A method and device for intelligent separation and extraction of hawthorn seeds and pulp, including a pulp separation box and a cleaning box. Inside the pulp separation box, a first crushing roller is rotatably connected. On the side of the first crushing roller away from the inner wall of the pulp separation box, a second crushing roller is provided. The first crushing roller is drivingly connected to a connecting rod. A cam for jittering one side of the pulp screening plate is sleeved on the surface of the connecting rod. The side of the pulp screening plate is rotatably connected to the inner wall of the pulp separation box. A ramp opening box is fixedly connected below the pulp separation box. A support column is fixedly connected to the side of the cleaning box. A cross brace is provided above the support column. A disc is suspended from the bottom of the cross brace. A prismatic soft brush is provided at the bottom of the disc. An impurity filtering plate is provided inside the cleaning box. A filtering circular plate is opened at the bottom of the cleaning box.

[0007] The above technical solution further includes:

[0008] The first crushing roller is drivingly connected to a first transmission belt. One end of the first transmission belt away from the first crushing roller is drivingly connected to the second crushing roller. The second crushing roller is drivingly connected to a second transmission belt. One end of the second transmission belt away from the second crushing roller is drivingly connected to the output end of a box-side motor. The box-side motor is fixed on the side of the pulp separation box. The first crushing roller is drivingly connected to a long belt. One end of the long belt away from the first crushing roller is drivingly connected to the connecting rod.

[0009] Multiple groups of long nozzles are provided inside the cleaning box. A suction pump is provided on the side of the cleaning box. One end of the suction pump is provided with a pipeline leading to a water delivery pump body. A pipeline for delivering water is provided on the side of the water delivery pump body. The multiple groups of long nozzles can form a uniform water flow to comprehensively wash the seeds, effectively washing away the pulp debris and impurities remaining on the surface of the seeds and the impurity filtering plate. The suction pump, in cooperation with the water delivery pump body and the pipeline, constitutes a water circulation system, which can timely pump away the sewage after cleaning and filter it, and re-deliver clean water source for cleaning.

[0010] Multiple groups of output motors are provided below the disc. The output ends of the output motors are fixedly connected to the prismatic soft brushes. The multiple groups of output motors independently control the prismatic soft brushes, and can flexibly adjust the rotation speed and direction of the brushes according to the remaining pulp on the surface of the seeds, realizing precise friction separation. At the same time, the decentralized power output avoids excessive load on a single motor, improves the operation stability and service life of the equipment, and the soft brush material can, while strongly removing dirt, maximally protect the integrity of the seeds.

[0011] A support frame is fixedly connected to the side of the pulp separation box. A chassis is provided at the bottom of the support frame. The support frame and the chassis form a stable support structure, enhancing the overall stability of the equipment, preventing the pulp separation box from shifting or toppling due to vibration during the crushing and screening processes. At the same time, the chassis can isolate the ground moisture, avoid damage to the components at the bottom of the equipment due to moisture, extend the service life of the equipment, and ensure production safety.

[0012] A pulp collection port is provided on the side of the pulp separation box. Support bars for supporting the pulp screening plate are arranged inside the pulp separation box. An electric door controller is fixedly connected to the side of the pulp separation box, and the electric door controller is used to control the opening and closing of the sliding door for the pulp collection port. The pulp collection port facilitates the centralized collection of large pieces of screened pulp, realizing the efficient recycling of pulp resources. The support bars provide stable support for the pulp screening plate, ensuring its structural strength and stability during the jittering process of the cam. The electric door controller cooperates with the sliding door to achieve automatic opening and closing, which can prevent impurities from entering during the pulp collection process and is convenient for operators to control the collection rhythm.

[0013] An expansion rod is rotatably connected to the side of the support column, and a cross support bar is fixedly connected above the expansion rod. The expansion rod and the rotational connection structure enable the cross support bar to flexibly adjust its height and angle, capable of precisely controlling the lifting and position of the disc and the prism soft brush. During seed cleaning, it can be inserted into the water to fully contact the seeds, and can quickly withdraw after cleaning is completed, facilitating subsequent cleaning and seed collection.

[0014] Multiple groups of cams for jittering the pulp screening plate are arranged on the surface of the connecting rod. Multiple groups of cams can form continuous and regular jittering forces, significantly improving the jitter frequency and effect of the pulp screening plate compared to a single group of cams, enabling the seeds and pulp to be separated more quickly and thoroughly. By reasonably designing the shape and arrangement of the cams, the jitter amplitude can also be optimized, avoiding damage to the seeds or the pulp screening plate due to excessive force, and improving the separation efficiency and equipment reliability.

[0015] Ribs for increasing the jitter stability are arranged at the bottom of the pulp screening plate. The ribs effectively enhance the structural strength and rigidity of the pulp screening plate. During the high-frequency jittering process of the cam, the risk of deformation and bending of the screening plate is reduced, ensuring its stable screening performance. At the same time, the stable jitter state helps to maintain the consistency of seed and pulp separation, avoiding incomplete screening of some seeds or mixing of pulp into the seed flow due to abnormal shaking of the screening plate, and improving the separation quality and production accuracy.

[0016] The present invention has the following beneficial effects:

[0017] 1. In the present invention, through the design of the first crushing roller and the second crushing roller in cooperation with the pulp screening plate, and by using precise spacing control between the crushing rollers, efficient crushing of hawthorns and preliminary separation of seeds are achieved, replacing manual operation. Compared with traditional manual separation, it can significantly reduce labor input. At the same time, it avoids pulp waste caused by excessive rolling of simple machinery, improves the pulp utilization rate, reduces the raw material loss cost, and is suitable for the low-cost and high-efficiency production requirements of small-scale workshops.

[0018] 2. In the present invention, a combined method of rotating and rubbing with a prismatic soft brush in a water environment and flushing with a long nozzle is adopted. While gently removing the residual pulp and impurities on the seed surface, mechanical damage to the seeds is avoided, significantly reducing the seed breakage rate. The setting of the impurity filter plate and the water circulation system ensures a clean and efficient separation process. The finally obtained seeds have high purity and good integrity, which is beneficial for subsequent seed breeding and also meets the quality requirements for deep processing with seeds as raw materials.

[0029] In one embodiment, for the long nozzle 23, multiple groups of long nozzles 23 are provided inside the cleaning box 17. A suction pump 25 is provided on the side of the cleaning box 17. One end of the suction pump 25 is provided with a pipeline leading to a water delivery pump body 26. A pipeline for delivering water is provided on the side of the water delivery pump body 26.

[0030] In this embodiment, multiple groups of long nozzles 23 can form a uniform water flow to comprehensively wash the seeds, effectively washing away the pulp debris and impurities remaining on the surface of the seeds and the impurity filtering plate 22. The suction pump 25, in cooperation with the water delivery pump body 26 and the pipeline, constitutes a water circulation system, which can timely pump away the sewage after cleaning and filter it, and re-deliver clean water for cleaning.

[0031] In one embodiment, for the disc 20, multiple output motors are provided below the disc 20. The output ends of the output motors are fixedly connected to the prismatic soft brush 21.

[0032] In this embodiment, multiple output motors independently control the prismatic soft brush 21, and can flexibly adjust the brush speed and rotation direction according to the pulp residue on the surface of the seeds to achieve precise friction separation. At the same time, the decentralized power output avoids excessive load on a single motor, improves the operation stability and service life of the device, and the soft brush material can, while strongly removing dirt, maximally protect the integrity of the seeds.

[0033] In one embodiment, for the support frame 1, the side of the pulp separation box 2 is fixedly connected to the support frame 1, and a chassis is provided at the bottom of the support frame 1.

[0034] In this embodiment, the support frame 1 and the chassis form a stable support structure, enhancing the overall stability of the equipment, preventing the pulp separation box 2 from generating displacement or tipping due to vibration during crushing and screening. At the same time, the chassis can isolate the moisture from the ground, avoid damage to the components at the bottom of the equipment caused by moisture, extend the service life of the equipment, and ensure production safety.

[0035] In one embodiment, for the above-mentioned pulp separation box 2, a pulp collection port 14 is provided on the side of the pulp separation box 2.

An electric door controller 11 is fixedly connected to the side of the pulp separation box 2, and the electric door controller 11 is used to control the opening and closing of the sliding door 12 for the pulp collection port 14.

[0036] In this embodiment, the pulp collection port 14 facilitates the centralized collection of the screened large pieces of pulp, realizing the efficient recycling of pulp resources. The support bar 15 provides a stable support for the pulp screening plate 13, ensuring its structural strength and stability during the shaking of the cam 10. The electric door controller 11 cooperates with the sliding door 12 to achieve automatic opening and closing, which can prevent impurities from entering during the pulp collection process and is convenient for the operator to control the collection rhythm.

[0037] In one embodiment, for the above-mentioned support column 18, a telescopic rod is rotatably connected to the side of the support column 18, and a cross brace 19 is fixedly connected above the telescopic rod.

[0038] In this embodiment, the telescopic rod and the rotational connection structure enable the cross brace 19 to flexibly adjust its height and angle, capable of precisely controlling the lifting and position of the disc 20 and the prism soft brush 21. When cleaning the seeds, it can be inserted into the water to fully contact the seeds, and can quickly withdraw after cleaning, facilitating subsequent cleaning and seed collection.

[0039] In one embodiment, for the above-mentioned connecting rod 9, a plurality of cams 10 for shaking the pulp screening plate 13 are arranged on the surface of the connecting rod 9.

[0040] In this embodiment, multiple cams 10 can form continuous and regular shaking forces, greatly improving the shaking frequency and effect of the pulp screening plate 13 compared with a single cam, enabling the seeds and pulp to be separated more quickly and thoroughly. By reasonably designing the shape and arrangement of the cams 10, the shaking amplitude can also be optimized, avoiding damage to the seeds or the pulp screening plate 13 due to excessive force, and improving the separation efficiency and equipment reliability.

[0041] In one embodiment, for the above-mentioned pulp screening plate 13, ribs for increasing shaking stability are arranged at the bottom of the pulp screening plate 13.

[0042] In this embodiment, the ribs effectively enhance the structural strength and rigidity of the pulp screening plate 13, and reduce the risk of deformation and bending of the screening plate during the high-frequency shaking of the cam 10, thereby ensuring the stability of its screening performance. At the same time, the stable shaking state helps to maintain the consistency of separation between seeds and pulp, avoiding incomplete screening of some seeds or mixing of pulp into the seed flow due to abnormal shaking of the screening plate, thereby improving separation quality and production accuracy.

[0043] The working principle of the intelligent separation and extraction equipment for hawthorn seeds and pulp in the present invention is that first, the intact hawthorns are selected to ensure that there are no bad fruits, so as to prevent the subsequent pulp collection from being collected together with the good pulp and affecting the subsequent use. After the intact hawthorns are selected, they are fed into the support frame 2 from the feeding port opened above the support frame 2. During the process of adding the hawthorns, the speed should be moderate to prevent the equipment from being blocked.

[0044] When the hawthorns enter the inside of the pulp separation box 2, there is a narrow gap between the first crushing roller 3 and the second crushing roller 4 at first. At this time, when the hawthorns pass between the first crushing roller 3 and the second crushing roller 4, the hawthorns will be crushed by the first crushing roller 3 and the second crushing roller 4. Since the distance set between the first crushing roller 3 and the second crushing roller 4 is just slightly larger than the width of the hawthorn seeds, in the case where the hawthorn pulp is flattened or the hawthorn seeds still have a little pulp, after passing through the first crushing roller 3 and the second crushing roller 4, they will fall onto the surface of the pulp screening plate 13 inside the pulp separation box 2. At this time, when the first crushing roller 3 rotates, it will drive the connecting rod 9 to rotate by means of the long belt 8. The rotation of the connecting rod 9 further uses multiple groups of cams 10 fixed on its surface to cyclically shake the pulp screening plate 13, so that the hawthorn seeds are separated from the pulp. Even if they are not separated, after the pulp screening plate 13 shakes multiple times, the seeds with pulp can also pass through the pulp screening plate 13. On the contrary, the large pieces of pulp cannot pass through the pulp screening plate 13. Then, after the hawthorn seeds pass through the pulp screening plate 13, they will slide along the slope inside the slope opening box 16 and then into the inside of the cleaning box 17. An impurity filtering plate 22 is arranged inside the cleaning box 17. At this time, the hawthorn seeds will accumulate on its surface. At this time, control the cross brace 19 to slide upward along the inside of the support column 18 and then rotate, so that the disc 20 at the bottom of the cross brace 19 is just inside the cleaning box 17. At this time, control the multiple groups of motors below the disc 20 to rotate, so as to drive the multiple groups of prism soft brushes 21 to rotate. Before that, control the water delivery pump body 26 to convey water along the pipeline into the cleaning box 17 until it submerges the hawthorn seeds with residues. At this time, control the prism soft brushes 21 to rotate. The distance between the multiple groups of prism soft brushes 21 is very small and the surfaces are all made of soft materials. Therefore, when rotating, they will rub the residues on the surface of the hawthorn seeds and further separate the pulp. Subsequently, stop the rotation of the multiple groups of prism soft brushes 21, and then control the cross brace 19 to rise above the support column 18 and rotate to the outside of the cleaning box 17. At this time, after the pulp on the surfaces of most of the hawthorn seeds is rubbed off, it will be rinsed by the long strip nozzle 23 to wash away the impurities, so that the impurities will enter the bottom of the cleaning box 17 along the impurity filtering plate 22 inside the cleaning box 17. Before that, the remaining water will be pumped away by the suction pump 25 and filtered through the filtering circular plate 24. At this time, the water can be recycled, and the impacted residues will remain at the bottom of the cleaning box 17. After a period of time, disassemble the impurity filtering plate 22 and clean the residues at the bottom of the cleaning box 17. At this time, the hawthorn seeds above the impurity filtering plate 22 can be taken away for subsequent processing.

[0045] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
