Description

TECHNICAL FIELD

[0001] The application relates to the technical field of food processing, in particular to a broken residue filtering device for white lotus can production. BACKGROUND

[0002] In the industrialized production process of white lotus cans, loose broken residues are often attached to the surface of lotus seeds after the precooking link, if the broken residues enter the sugar water system with the finished product, not only will the contents of the cans be turbid and the sensory quality be reduced, but also consumer complaints may be caused due to the residue residues, and the market reputation of the product is affected. Therefore, efficient removal of the broken residues in the lotus seeds after precooking is a key link for improving the quality of white lotus cans.

[0003] At present, the industry generally uses a vibrating screen as the main equipment for broken residue separation. However, the vibrating screen realizes screening through high-frequency vibration, and in this process, the lotus seeds and the screen mesh repeatedly collide and rub, which easily causes the lotus seed skin to be damaged or even the tissue to be broken, and therefore, the application provides a broken residue filtering device for white lotus can production. SUMMARY

[0004] The application aims to provide a broken residue filtering device for white lotus can production, which has the advantages that a mesh plate that vibrates up and down in a water body is arranged, and the broken residues in the lotus seeds are carried away by the water flow from bottom to top, so that the damage of the lotus seeds caused by the filtering of the broken residues is reduced, and the problem that the lotus seeds are damaged when the broken residues are separated by using the vibrating screen in the traditional process is solved.

[0005] It is particularly pointed out that the application is batch operation, but the original intention of the design is to realize efficient separation of the broken residues on the premise of ensuring the integrity of the lotus seeds. Compared with a continuous production line, the device is more suitable for the production process of white lotus cans with extremely high product quality requirements, and is especially suitable for high-end product lines with small batches and multiple varieties. By optimizing the operation process, the beat demand of the production line can still be met.

[0006] In addition, the filter plate of the application is arranged above the mesh plate, and through the synergistic effect of the vibration of the mesh plate and the water flow injection, when the mesh plate descends, the water flow can pass through the mesh plate to upwardly disperse the lotus seeds, lift the broken residues, and then make the broken residues enter the residue filtering barrel along with the water flow.

[0007] In order to reduce the quality risk caused by long-time soaking of the lotus seeds, the application suggests that the processing time of a single batch is controlled to be within 5-8 minutes, and by adjusting the water flow intensity and the vibration frequency, the soaking time of the lotus seeds is shortened to the maximum extent while the separation efficiency of the broken residues is ensured, so that excessive water absorption is avoided. If the production process allows, a proper amount of food-grade color protection agent or hardening agent can be added in the water to further maintain the shape and taste of the lotus seeds.

[0008] In terms of maintenance, the filter plates and diversion holes adopt a quick-disassembly structure design, which is convenient for regular cleaning; key moving parts such as gears, racks, and impellers are made of stainless steel and coated with wear-resistant and corrosion-resistant coatings, which improves the durability of the equipment in humid environments and reduces the frequency and cost of long-term maintenance.

[0009] To achieve the above objectives, the present invention provides the following technical solution: a residue filtering device for white lotus seed canning production, comprising: a barrel body filled with water, a top cover that can be opened and closed, and a base fixedly mounted at the bottom; a mesh plate disposed within the barrel body and slidingly engaged with the inner wall of the barrel body, with a support frame at the bottom of the mesh plate; a residue filter barrel fixedly mounted on the base and connected to the barrel body via a circulating water path for collecting and discharging residue; a filter plate disposed at the outlet end of the circulating water path for preventing lotus seeds from entering the residue filter barrel; a drive assembly for driving the mesh plate to vibrate up and down; and a control assembly linked to the drive assembly for synchronously controlling the opening and closing of the circulating water path.

[0010] Preferably, the circulating water circuit includes an inlet pipe fixedly installed at the bottom of the tank, a valve body connected to the inlet pipe, a water pump, and an outlet pipe connecting the filter cake bucket and the tank body. The outlet pipe is fixed to the filter cake bucket via a flange. The valve body is fixed to the outside of the mounting bracket fixedly installed on the base. The water pump is connected and fixed to the valve body and the filter cake bucket via a pipe. The water pump is fixedly installed on the base and drives the water flow to form a circulation.

[0011] Preferably, the end of the water inlet pipe that extends into the tank is a right-angle bend, with its end closed and diversion holes opened around it to evenly distribute the water flow.

[0012] Preferably, the drive assembly includes a drive motor, a drive shaft, and elliptical wheels symmetrically fixed on the drive shaft. The drive motor is fixed on the base, and the drive shaft is driven and connected to the output end of the drive motor. The drive shaft is rotatably connected to the barrel body. An elliptical track groove is provided on the outer side of the wheel. The support frame is slidably engaged with the inner side of the barrel body. A T-shaped support block that slidably engages with the track groove is fixed at the bottom of the support frame. A spring telescopic rod is fixed at the bottom of the barrel lid. The spring telescopic rod abuts against the top of the mesh plate, and the mesh plate vibrates due to the rotation of the wheel.

[0013] Preferably, the control component includes an auxiliary wheel fixed coaxially with the drive shaft. The auxiliary wheel is located on the outside of the barrel body, and an elliptical groove is provided on the outside of the auxiliary wheel. A slider is slidably connected in the groove. The slider is linked with the valve stem of the valve body through the transmission of gears and racks, so that the valve body opens when the screen plate descends and closes when the screen plate rises. The gear is located in the mounting box at the top of the mounting frame. There are two racks, which are symmetrically arranged on both sides of the gear and slidably connected to the mounting box. One rack is fixed to the slider, and the other rack is fixed to the valve stem of the valve body.

[0014] Preferably, the inner side of the track groove of the impeller is provided with a pressure relief hole for discharging water from the track groove.

[0015] Preferably, a surrounding plate is fixedly provided on the top of the screen, and symmetrically distributed handles are fixed on the inner side of the surrounding plate for operators to extract lotus seeds after filtering the residue.

[0016] Preferably, the pore size of the filter plate and the mesh plate is smaller than the minimum particle size of lotus seeds, and they are made of stainless steel.

[0017] Preferably, the speed of the drive motor is adjustable to control the vibration frequency of the mesh plate.

[0018] Preferably, the surfaces of the gears and racks are coated with a wear-resistant coating to extend their service life.

[0019] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention fills the tank with water, which then flows over the moving mesh plate and lotus seeds. The low-frequency vibration of the mesh plate, combined with the water circulation, replaces the violent collision of the traditional high-frequency vibrating screen, achieving the separation of fragments while effectively avoiding damage to the skin and tissues of the lotus seeds.

[0020] 2. This invention achieves precise synchronization between the vibration of the mesh plate and the opening and closing of the circulating water path through the linkage design of the drive component and the control component: when the mesh plate is pressed down, the water flow is turned on to flush away the debris, and when the mesh plate is raised, the water flow is turned off to prevent the lotus seeds from flowing back.

[0021] 3. This invention uses the double barrier of the filter plate and the filter cake bucket to ensure that the debris is discharged unidirectionally into the filter cake bucket with the water flow. At the same time, the design of the diversion hole allows the water to enter the bucket evenly, flow along the mesh plate, and wash away the lotus seeds and debris in the water, thereby improving the cleaning efficiency of the debris.

Detailed Implementation

[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] Example 1: Please refer to Figure 1 - Figure 8 The diagram shows a residue filtering device for white lotus seed canning production, comprising: a barrel 1 filled with water, a top cover 2 that can be opened and closed, and a base 3 fixedly mounted at the bottom; a mesh plate 4 disposed inside the barrel 1 and slidingly engaged with the inner wall of the barrel 1, with a support frame 5 at the bottom of the mesh plate 4; a residue filter 6 fixedly mounted on the base 3 and connected to the barrel 1 via a circulating water passage 7 for collecting and discharging residue; a filter plate 8 located at the outlet of the circulating water passage 7 for preventing lotus seeds from entering the residue filter 6; a drive assembly 9 for driving the mesh plate 4 to vibrate up and down; and a control assembly 10 linked to the drive assembly 9 for synchronously controlling the opening and closing of the circulating water passage 7. This device achieves gentle separation of lotus seed fragments through the coordinated operation of the tank 1, mesh plate 4, filter cake 6, filter plate 8, drive assembly 9, and control assembly 10. Water is injected into the tank 1 to provide a buoyant buffer environment for the lotus seeds; the mesh plate 4 vibrates up and down to detach the fragments from the lotus seed surface; the filter cake 6, in conjunction with the circulating water path 7, collects the fragments in a directional manner; the filter plate 8 acts as a physical barrier to prevent lotus seeds from accidentally entering the filter cake 6; the drive assembly 9 drives the mesh plate 4 to vibrate via mechanical transmission, while the control assembly 10 precisely regulates the opening and closing rhythm of the circulating water path 7 to ensure the synchronization of fragment separation and water rinsing. Through structural linkage and functional complementarity, the various components solve the problem of traditional vibrating screens easily damaging lotus seeds.

[0026] The circulating water circuit 7 includes an inlet pipe 11 fixedly installed at the bottom of the tank 1, a valve body 12 connected to the inlet pipe 11, a water pump 13, and an outlet pipe 14 connecting the filter cake container 6 and the tank 1. The outlet pipe 14 is fixed to the filter cake container 6 via a flange. The valve body 12 is fixed to the outside of a mounting bracket 15 fixedly installed on the base 3. The water pump 13 is connected and fixed to the valve body 12 and the filter cake container 6 via a pipe. The water pump 13 is fixedly installed on the base 3 and drives the water flow to form a circulation. The inlet pipe 11 allows water to be injected evenly from the bottom of the tank 1. The synergistic action of the valve body 12 and the water pump 13 forms a circulating water flow. The outlet pipe 14 is fixedly connected to the filter cake container 6 via a flange, ensuring that the filter cake is discharged unidirectionally with the water flow. The water pump 13 is fixed on the base 3 and connected to the valve body 12 and the filter cake container 6 via a pipe, forming a closed-loop circulation system. This design not only improves the efficiency of water flushing, but also reduces the secondary deposition of debris in the barrel 1 through the dynamic circulation of water flow, thus optimizing the filtration effect. Furthermore, the end of the water inlet pipe 11 that extends into the barrel 1 is a right-angle bend, with its end closed and diversion holes 31 opened around its perimeter. The even distribution of the diversion holes 31 causes the water flow to form a multi-directional jet from bottom to top within the barrel 1, covering the entire area of ​​the mesh plate 4, thus preventing excessive local water flow from causing lotus seeds to accumulate or be washed unevenly. This structure enhances the dispersion and coverage of the water flow, effectively breaking up debris between lotus seeds, while reducing the impact force of the water flow on individual lotus seeds, further reducing the risk of breakage.

[0027] The drive assembly 9 includes a drive motor 16, a drive shaft 17, and elliptical wheels 18 symmetrically fixed on the drive shaft 17. The drive motor 16 is fixed on the base 3. The drive shaft 17 is driven and connected to the output end of the drive motor 16. The drive shaft 17 is rotatably connected to the barrel 1. The outer side of the wheel 18 is provided with an elliptical track groove 19. The support frame 5 is slidably engaged with the inner side of the barrel 1. The bottom of the support frame 5 is fixed with a T-shaped support block 20 that is slidably engaged with the track groove 19. The bottom of the barrel cover 2 is fixed with a spring telescopic rod 21. The spring telescopic rod 21 abuts against the top of the mesh plate 4. The rotation of the wheel 18 drives the mesh plate 4 to vibrate. The drive motor 16 has an adjustable speed to control the vibration frequency of the mesh plate 4. Operators can adjust the motor speed to match the optimal vibration parameters based on the particle size, hardness, and other characteristics of different batches of lotus seeds. This ensures efficient separation of broken pieces while avoiding damage to the lotus seeds due to excessive vibration, thus improving the adaptability and process compatibility of the device. The principle of the drive assembly 9 driving the vibration of the mesh plate 4: The drive motor 16 drives the elliptical wheel 18 to rotate through the drive shaft 17. The track groove 19 on the outer side of the wheel 18 slides with the T-shaped support block 20 at the bottom of the support frame 5, converting the rotational motion into the vertical vibration of the mesh plate 4. The spring telescopic rod 21 is fixed to the bottom of the bucket lid 2, providing elastic support to the top of the mesh plate 4, which both buffers the vibration impact and ensures the stability of the mesh plate 4's movement. The symmetrical layout of the elliptical wheel 18 makes the vibration trajectory of the mesh plate 4 uniform, avoiding mechanical wear caused by uneven loading.

[0028] The control component 10 includes an auxiliary wheel 22 fixed coaxially with the drive shaft 17. The auxiliary wheel 22 is located on the outside of the barrel 1. An elliptical groove 23 is provided on the outside of the auxiliary wheel 22. A slider 24 is slidably connected in the groove 23. The slider 24 is linked with the valve stem of the valve body 12 through the transmission of the gear 25 and the rack 26, so that the valve body 12 opens when the mesh plate 4 descends and closes when the mesh plate 4 rises. The gear 25 is rotatably located in the mounting box 27 provided on the top of the mounting frame 15. There are two racks 26, which are symmetrically arranged on both sides of the gear 25 and slidably connected to the mounting box 27. One rack 26 is fixed to the slider 24, and the other rack 26 is fixed to the valve stem of the valve body 12. The principle of the control component 10 driving the valve body 12 to open and close is as follows: The auxiliary wheel 22 is coaxially fixed with the drive shaft 17, achieving precise control through mechanical linkage. The elliptical groove 23 on the outer side of the auxiliary wheel 22 cooperates with the slider 24. The slider 24 drives the valve stem of the valve body 12 through the transmission of gear 25 and rack 26. When the screen plate 4 is pressed down, the slider 24 moves along the trajectory of the groove 23, pushing the connected rack 26 to rotate the gear 25, which in turn pulls the rack 26 on the other side of the gear 25 to open the valve body 12, thus opening the circulating water path 7. When the screen plate 4 rises, the valve body 12 closes simultaneously, blocking the water flow. This linkage design ensures that the water flow only flushes away debris during the downward pressure phase of the screen plate 4, preventing the lotus seeds from shifting or flowing back due to reverse water flow, thus improving filtration efficiency and operational reliability.

[0029] It is worth noting that a surrounding plate 29 is fixedly installed on the top of the screen plate 4, and symmetrically distributed handles 30 are fixed on the inner side of the surrounding plate 29 for operators to extract lotus seeds after filtering residue. The surrounding plate 29 prevents lotus seeds from overflowing from the screen plate 4 during water flow or vibration, ensuring that all lotus seeds are in the effective filtration area. The design of the handles 30 makes it easy for operators to quickly extract lotus seeds after filtration, reducing the complexity and time cost of manual operation and improving overall production efficiency.

[0030] Furthermore, the pore sizes of both filter plate 8 and mesh plate 4 are smaller than the minimum particle size of lotus seeds, and they are made of stainless steel. Stainless steel is corrosion-resistant, high-strength, and suitable for long-term humid environments. The pore size design of filter plate 8 ensures that debris passes through with the water flow, while lotus seeds are effectively blocked, avoiding material loss. Moreover, filter plate 8 can be designed as a detachable structure for easy cleaning and maintenance, ensuring the long-term reliability of the device.

[0031] The implementation steps of this technical solution are as follows: S1. The operator opens the bucket lid 2, spreads the pre-cooked lotus seeds evenly on the mesh plate 4, pours clean water into the bucket 1, and the water level must completely cover the lotus seeds on the mesh plate 4 in the subsequent movement range. The buoyancy of the water reduces the direct collision between the lotus seeds and the mesh plate 4. The bucket lid 2 is closed to ensure a seal. The drive motor 16 is started, and the motor speed is adjusted through the external control panel to set a vibration frequency suitable for the current characteristics of the lotus seeds. S2. The drive motor 16 drives the drive shaft 17 to rotate, and the symmetrically fixed elliptical wheel 18 on the drive shaft 17 rotates accordingly. The elliptical track groove 19 on the outer side of the wheel 18 slides with the T-shaped support block 20 at the bottom of the support frame 5, converting the rotational motion into the vertical up-and-down vibration of the mesh plate 4. During this process, the spring telescopic rod 21 fixed at the bottom of the bucket lid 2 applies elastic support to the top of the mesh plate 4, buffering the vibration impact and ensuring that the mesh plate 4 moves smoothly. In addition, during the vibration of the mesh plate 4, the lotus seeds are loosened and separated by the low-frequency vibration, and the debris attached to the surface gradually falls off. S3. When the drive shaft 17 rotates, the auxiliary wheel 22, which is fixed coaxially with it, rotates synchronously. The elliptical groove 23 on the outer side of the auxiliary wheel 22 drives the slider 24 to slide up and down, thereby driving the valve stem of the valve body 12 to move up and down through the gear 25 and rack 26 transmission mechanism. The specific situation is as follows: During the descent of the mesh plate 4, the slider 24 moves outward along the track of the slide groove 23, pushing the rack 26 to drive the gear 25 to rotate, and the rack 26 on the other side pulls the valve stem to open the valve body 12; During the upward movement of the mesh plate 4, the slider 24 moves in the opposite direction, and the valve stem is pushed by the rack 26 to close the valve body 12, blocking the water flow; After the valve body 12 is opened, the water pump 13 starts and pumps the water in the tank 1 into the circulating water circuit 7 through the water inlet pipe 11. S4. Water enters from the inlet pipe 11 at the bottom of the barrel 1. The end of the inlet pipe 11 is a right-angle bend. The diversion holes 31 around it evenly disperse the water flow, forming a multi-directional jet from bottom to top. The water flow passes through the mesh plate 4 and impacts the lotus seeds on the mesh plate 4, further dispersing the debris. The debris is carried by the water flow through the filter plate 8 and flows into the filter cake bucket 6 through the outlet pipe 14. After the debris is filtered in the filter cake bucket 6, the clean water is re-injected into the barrel 1 by the water pump 13, forming a closed loop. The debris remains in the filter cake bucket 6, which can be cleaned by the operator periodically. Although this unit operates in batches, non-operational time can be minimized through advance material preparation and alternating dual-station operations, and its actual production efficiency can meet the needs of small and medium-sized canning production lines. For continuous production, multiple units of this unit can be operated in parallel.

[0032] It is worth noting that when the mesh plate 4 descends, the water flow impacts the lotus seeds on the mesh plate 4, further breaking up the debris. The debris is carried by the water flow through the upper filter plate 8 and flows into the filter cake bucket 6 through the outlet pipe 14. During this process, the water level in the bucket 1 will always be higher than the filter plate 8, ensuring that the debris can be discharged with the water flow. It is also recommended that the processing time for each batch be controlled within 5-8 minutes to avoid the lotus seeds absorbing too much water, which would affect the taste. If the water hardness is high or the lotus seeds have a lot of mucus, food-grade citric acid or calcium salts can be added to the water to reduce scaling and mucus adhesion.

[0033] S5. After filtration, turn off the drive motor 16 and water pump 13. The screen plate 4 stops vibrating, the circulating water circuit 7 is terminated, the operator opens the bucket lid 2, and lifts the filtered lotus seeds along with the screen plate 4 through the symmetrical handles 30 on the top of the screen plate 4. The surrounding plate 29 can prevent the lotus seeds from scattering, thus completing the lotus seed filtration operation.

[0034] To reduce maintenance frequency, it is recommended to flush and clean the filter plate 8, diversion hole 31 and circulating water path 7 after every 10-12 batches of operation. By using stainless steel to make key moving parts such as gear 25, rack 26 and impeller 18 and coating them with wear-resistant and corrosion-resistant coating, the durability of the equipment in humid environments can be improved, thereby reducing the frequency and cost of long-term maintenance.

[0035] Example 2: This embodiment further explains Example 1, the difference being the optimization of the rotating wheel 18; Specifically, the inner side of the track groove 19 of the rotor 18 is provided with a pressure relief hole 28. During the operation of the device, since the rotor 18 rotates in the water, when the T-shaped support block 20 slides in the track groove 19, the T-shaped support block 20 will squeeze the water in the track groove 19, increasing the resistance to the movement of the support block 20. The added pressure relief hole can discharge the squeezed water in the track groove 19 in time, reduce the resistance to the movement of the support block 20, and ensure the smooth cooperation between the T-shaped support block 20 and the track groove 19.

[0036] Example 3: This embodiment further explains Example 1, the difference being the optimization of gear 25 and rack 26; Specifically, gear 25 and rack 26 are coated with a wear-resistant coating. Under frequent start-stop and high-load operating conditions, the coating effectively delays component aging, reduces maintenance frequency, and extends the overall service life of the device. At the same time, the wear-resistant coating also reduces operating noise and improves the working environment.
