Description

Technical Field

[0001] This application relates to the field of continuous sieving device technology, and in particular to a continuous sieving device for jujube kernels. Background Technology

[0002] Traditionally, the process of removing the kernels from jujube seeds relies on manual sun-drying and tumbling. This method is not only time-consuming (usually requiring two to five days of sun-drying), but also labor-intensive and inefficient. During the sun-drying process, jujubes are easily affected by the weather, leading to unstable quality. In addition, although repeated crushing with round stones can remove the kernels, it is difficult to ensure the integrity of the kernels, and the separation effect is not good, making it difficult to meet the needs of modern, large-scale production. Utility Model Content

[0003] The problem this application aims to solve is that when using the traditional sun-drying and tumbling method to remove the pulp from jujube seeds, the kernels after crushing are not very intact, making them difficult to separate effectively.

[0004] To solve the above-mentioned technical problems, this application provides a continuous sieving device for jujube kernels, including a frame, a shell at one end of the upper part of the frame, a peeling component that uses a rotating impact method to separate the pulp and kernel of jujubes, a sieving component that uses a linear vibration method to sieve the pulp and kernel after impact at the upper part of the frame, a blowing component that uses a high-pressure airflow to blow away impurities from the sieved kernels at the lower part of the frame, and a motor that uses a belt drive to simultaneously drive the peeling component, the sieving component and the blowing component at the upper part of the frame.

[0005] Because the continuous desieving device of this application is designed with a peeling component, a screening component, and a blowing component, the organic combination of the peeling component, screening component, and blowing component achieves efficient and continuous desieving and cleaning of jujube kernels. This solves the problem that when using the traditional sun-drying and trampling method to remove the pulp of jujube kernels in the prior art, the kernels after crushing have poor integrity, which makes them difficult to separate effectively.

[0015] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application. Example

[0016] This application relates to a continuous sieving device for jujube kernels, such as... Figure 1-8 As shown, the continuous jujube removal device includes a frame 2, a housing 5, a peeling assembly, a screening assembly 1, and a blowing assembly 3. The frame 2 serves as the basic support structure for the entire device, and its stable design ensures the stable operation of all components. The housing 5 is located at one end of the upper part of the frame 2, providing a closed de-pulping space to reduce external interference and ensure the hygiene and safety of the de-pulping process. The peeling assembly is installed inside the housing 5 and operates using a rotating impact method. This assembly uses high-speed rotating impact elements to precisely and powerfully impact the jujubes entering the housing 5, effectively separating the pulp from the kernel, replacing the traditional manual crushing process. This greatly improves the efficiency of pulp removal and the integrity of the kernels. The screening component 1 is inclinedly arranged on the upper part of the frame 2 and adopts a linear vibration method. The screening component 1 screens the separated pulp and kernels through the mesh element on its upper part to ensure effective separation of the two for subsequent separate processing. The blowing component 3 is located below the frame 2 and is used to perform fine blowing operation on the screened kernels. It removes the small impurities mixed in the kernels through high-pressure airflow, further improving the purity of the product. On the upper part of the frame 2, a motor 4 is also arranged to drive the peeling component, screening component 1 and blowing component 3 simultaneously using belt drive.

[0017] During operation, the jujube is fed into the housing 5. The peeling component starts to rotate and beat under the drive of the motor 4, which quickly separates the pulp and kernel. The separated mixture directly enters the screening component 1 and is screened by linear vibration. After the pulp and kernel are collected separately, the kernel is finely blown away by the blowing component 3, and finally clean jujube kernel product is obtained.

[0018] The peeling assembly includes a roller frame 7, a roller screen 8, and striking claws 6. The roller frame 7 is horizontally placed inside the housing 5, and its two ends are fixedly connected to the housing 5 through bearing seats to ensure that the roller frame 7 can remain stable when rotating at high speed. The roller frame 7 is designed with high strength and wear resistance to meet the needs of long-term continuous operation. The striking claws 6 are key components on the roller frame 7 used to directly strike the jujubes to remove the flesh. They are evenly and spaced in the upper circumferential direction of the roller frame 7. Each striking claw 6 is curved, and the bending angle is precisely set to 120°. This design not only enhances the impact resistance of the striking claws 6, but also forms an effective force during the striking process. The shearing force allows for more efficient separation of the pulp and kernel. The striking claw 6 is made of high-strength, wear-resistant material to ensure long-term stability and durability. The roller screen 8 is located below the roller frame 7 and has a semi-circular design, arranged concentrically with the roller frame 7. The roller screen 8 consists of roller plates 9 and roller shafts 10. The roller shafts 10 are evenly and intermittently arranged in the middle of the upper part of the roller plate 9. The gap between the roller shafts 10 allows the jujube kernels and pulp to pass through smoothly after being struck, while effectively preventing unseparated sour jujubes from entering subsequent processes, ensuring effective separation of the product. The roller screen 8 is also made of wear-resistant and corrosion-resistant material to adapt to complex working environments.

[0019] When the jujubes enter the shell 5, the motor 4 drives the roller frame 7 to start rotating, and the striking claws 6 strike the jujubes at high speed. Due to the curved design of the striking claws 6 and the precise striking angle, the connection between the pulp and kernel of the jujubes is effectively broken when they are struck, achieving rapid separation. The separated mixture falls into the roller screen 8 below under the action of gravity and the centrifugal force generated by the rotation of the roller frame 7. The gap between the roller shafts 10 on the roller screen 8 allows the jujube kernels and pulp to pass through, while larger impurities are blocked above the roller screen 8 and then removed. In this way, the pulp and kernels are effectively separated and enter the subsequent screening and blowing processes respectively.

[0020] The screening assembly 1 includes a material frame 11, a screen plate 12, a crank 14, a connecting rod 13, a slide rail 15, and sliders 16. The material frame 11 is inclined inside the frame 2, and its inclination angle is optimized according to actual needs to ensure smooth flow of pulp and kernels during the screening process. Sliders 16 are symmetrically arranged on both sides of the material frame 11. These sliders 16 are connected to the slide rails 15 set on the upper part of the frame 2, forming the sliding system of the material frame 11. The screen plate 12 is the core component inside the material frame 11. This is used to separate fruit pulp and kernels. The sieve plate 12 has sieve holes of appropriate size and spacing, allowing kernels to pass through while blocking the pulp. After passing through the sieve holes, the kernels fall into the channel 19 between the bottom of the sieve plate 12 and the material frame 11, while the pulp continues to move forward along the surface of the sieve plate 12 and is eventually discharged from the other end of the sieve plate 12. The crank 14 is the key component that drives the material frame 11 to reciprocate. It is arranged on the upper part of the frame 2 and can rotate around its fixed point. One end of crank 14 is connected to the material frame 11, and power is transmitted through connecting rod 13, causing the material frame 11 to reciprocate on slide rail 15. Connecting rod 13 is the bridge connecting crank 14 and material frame 11, converting the rotational motion of crank 14 into the linear reciprocating motion of material frame 11. The design of connecting rod 13 takes into account strength and wear resistance to ensure long-term stable operation. Slide rail 15 and slider 16 constitute the sliding guide system of material frame 11. Slide rail 15 is fixed to the upper part of frame 2, and slider 16 is fixed to the upper part of frame 2. Providing a precise sliding path, the slider 16 is connected to the material frame 11. As the crank 14 rotates, the slider 16 slides on the slide rail 15, driving the material frame 11 to reciprocate. The other end of the crank 14 is connected to the motor 4 via belt drive. When the motor 4 starts, it transmits power to the crank 14 via belt drive, causing it to start rotating. The rotation of the crank 14 drives the material frame 11 to reciprocate on the slide rail 15 via the connecting rod 13, thereby realizing continuous screening of fruit pulp and kernels.

[0021] When the motor 4 starts, the crank 14 is driven to rotate via belt drive. The rotation of the crank 14 is converted into the reciprocating motion of the material frame 11 through the connecting rod 13. Under the guidance of the slide rail 15, the material frame 11 slides back and forth regularly along the inclined direction. At the same time, the mixture of pulp and kernel separated from the peeling component falls into the material frame 11. During the reciprocating motion of the material frame 11, the sieve plate 12 screens the mixture. Because the kernels are small, they can pass through the sieve holes on the sieve plate 12 and fall into the channel 19 between the sieve plate 12 and the bottom of the material frame 11, where they are collected. The pulp, because it is large, is blocked by the sieve plate 12 and continues to move forward along the surface of the sieve plate 12, and is finally discharged from the other end of the sieve plate 12.

[0022] The blowing assembly 3 includes a housing 17 and an impeller 18. The housing 17 is the main body of the blowing assembly 3, fixedly arranged below the frame 2, and connected to the outlet of the screening assembly 1. The design of the housing 17 takes into account the smoothness of airflow and noise control, ensuring the efficiency and quietness of the blowing process. A flat air outlet is provided on one side of the housing 17 to guide the wind generated by the impeller 18 to the kernels, while avoiding wind diffusion and waste. The impeller 18 is the core component of the blowing assembly 3. It is horizontally placed inside the housing 17 and can rotate at high speed to generate a powerful air source. The design of the impeller 18 takes into account the principles of aerodynamics. Through the precise blade shape and arrangement, it ensures that a stable and strong airflow can be generated when rotating. One end of the impeller 18 is connected to the motor 4 through a belt drive. When the motor 4 starts, it drives the impeller 18 to start rotating through the belt drive.

[0023] When the motor 4 starts, it drives the impeller 18 to rotate at high speed inside the casing 17 via belt drive. When the impeller 18 rotates, its blades cut the air and generate a strong wind. This wind is guided to the air outlet along the channel 19 inside the casing 17. At the same time, when the kernels falling from the screening component 1 pass through the air outlet, they are blown away by the wind. The wind blows away the fine fruit pulp impurities mixed in with the kernels, making the kernels cleaner. The blown-away impurities are then collected and processed by a special collection device, while the clean kernels continue to enter the subsequent processing steps.

[0024] In operation, after the jujubes are fed into the device, they first enter the peeling assembly. The motor 4 drives the roller frame 7 to rotate, and the striking claws 6 on the roller frame 7 strike the jujubes at high speed. The curved design and precise striking angle of the striking claws 6 effectively break the connection between the pulp and the kernel, causing the pulp and kernel to separate initially. The separated mixture (containing kernels, pulp, and a small amount of impurities) falls into the roller screen 8 below under the action of gravity and the centrifugal force generated by the rotation of the roller frame 7. The gap between the roller shafts 10 on the roller screen 8 allows the kernels and pulp to pass through, while larger impurities are blocked above the roller screen 8 and subsequently removed. The pulp and kernel mixture falling from the peeling assembly enters the material frame 11 of the screening assembly 1. The motor 4 drives the crank 14 to rotate via belt drive. The crank 14 drives the material frame 11 to reciprocate on the slide rail 15 via the connecting rod 13. During the reciprocating motion of the material frame 11, the sieve plate 12 screens the mixture. Due to their small size, the kernels can pass through the sieve holes on the sieve plate 12 and fall into the channel 19 between the sieve plate 12 and the bottom of the material frame 11, achieving further separation from the pulp. The pulp is blocked by the sieve plate 12 and continues to move forward along the surface of the sieve plate 12, eventually being discharged from the other end of the material frame 11 and entering the subsequent pulp processing process. The kernels separated by the sieve component 1 fall into the housing 17 of the blow-off component 3. The motor 4 drives the impeller 18 to rotate at high speed inside the housing 17, generating strong air force. The air force is guided along the channel 19 inside the housing 17 to the air outlet, blowing the kernels passing through the air outlet. The air force blows away the fine pulp impurities and remaining small particle impurities mixed in with the kernels, making the kernels cleaner. The blown-off impurities are collected and processed by a special collection device, while the clean kernels are discharged from the outlet of the blow-off component 3 and enter the subsequent packaging or further processing process.
