Description

Technical Field

[0001] This invention relates to the field of rice processing, specifically to a soaking and dehulling device for rice processing. Background Technology

[0002] Rice processing requires hulling, which removes the hard outer husk that is indigestible, exposing the edible brown rice inside. Common rice hulling devices are mainly dry hulling machines, which use mechanical force (squeezing, friction, impact) to tear the husk and brown rice layer. Based on the different forms of mechanical force, the main devices are divided into three categories: rubber roller hullers, sand disc hullers, and centrifugal hullers. Rubber roller hullers use squeezing and friction to hull, sand disc hullers use grinding and impact, and centrifugal hullers use impact and collision.

[0003] In rice hulling, rice husks and brown rice need to be separated. Traditional hulling devices rely on a combination of air separation and sieving for hulling. Air separation separates rice husks and brown rice through airflow differences. However, rice husks are easily broken by mechanical extrusion, producing fine powder. Due to static electricity or adhesion, the powder and rice husks are easily adsorbed onto the surface of brown rice. The impact force of conventional air separation airflow is insufficient to completely remove them, resulting in powder mixing into the brown rice and incomplete separation. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a soaking and dehulling device for rice processing, which solves the problem of incomplete separation of powder and rice husks during the air separation process.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a rice processing soaking and dehulling device, comprising a dehulling box body, the dehulling box body comprising a soaking pool and a collecting pool, a cylinder fixed to the soaking pool, a tube rotatably mounted at the bottom end of the cylinder, a slide rail fixedly connected to the outer side of the tube, the slide rail having a spiral continuous sliding structure, the slide rail having a continuous sliding curved surface for rice to slide, the extension trajectory of the slide rail's sliding curved surface being arranged in a multi-turn spiral from top to bottom along the vertical direction, and a preset distance being maintained between adjacent spiral trajectories.

[0006] The slide is immersed in the soaking tank. One end of the slide is used for feeding, and the other end is connected to the material cylinder. The bottom end of the material cylinder is rotatably connected to the discharge pipe, which is connected to the collection tank. The slide plate of the slide has several peeling grooves distributed along its spiral trajectory. Several auxiliary plates are slidably installed in the slide. The auxiliary plates include short plates and long plates. The short plates and long plates form an "eight" shape and fit against the slide.

[0007] Preferably, the auxiliary plate further includes a crossbar, which is fixedly installed between the short plate and the long plate.

[0008] Preferably, the cylinder is provided with several sets of slide rails, each set of slide rails is slidably connected to a connecting frame, each connecting frame is slidably connected to an "L"-shaped slide rod, one end of each slide rod is fixedly connected to a crossbar adjacent to it, and the other end of each slide rod has a "U"-shaped protrusion structure, and the protrusion of the slide rod is slidably connected to the connecting frame.

[0009] Preferably, the slide rail further includes a sliding shell with a sloping cross-section and a spiral opening therein, with one end of the slide rod slidably connected to the opening.

[0010] Preferably, the cross-sections at one end of both the short plate and the long plate are arc-shaped and in contact with the inner wall of the sliding shell.

[0011] Preferably, the slide plate has a plurality of screening holes inside, and the screening holes and stripping grooves are distributed alternately.

[0012] Preferably, the shelling box body also includes a top frame, support legs and two drain pipes. The top frame and support legs are fixedly connected to the soaking tank and the collection tank respectively. The two drain pipes are connected to the soaking tank and the collection tank respectively. Each of the two drain pipes is connected to a valve. One end of the cylinder is fixedly connected to the top frame.

[0013] Preferably, a hydraulic rod is fixedly installed in the shelling box body, a fixed block is fixedly connected to the output end of the hydraulic rod, a push-pull plate is fixedly connected to the outside of the material cylinder, a groove is provided in the push-pull plate, a fixed column is slidably connected in the groove, and the fixed column is fixedly connected to the fixed block.

[0014] Preferably, an aeration pipe is fixedly connected to the shelling box body, the aeration pipe is equipped with a one-way valve, one end of the aeration pipe is connected to the discharge pipe, and the aeration pipe is used for intermittent upward air jet.

[0015] Preferably, an annular material box is installed on the top frame, and a telescopic tube is connected to the bottom of the material box. One end of the telescopic tube is fixed in the slide rail, and a screen is installed inside the material box.

[0016] Compared with the prior art, the present invention has the following beneficial effects: The spiral conical slide adopts multiple spiral rings. When the slide rotates back and forth with a small amplitude, it forms a downward sliding and upward rotational force on the rice. The inertia of the rice sliding down the curved surface and the tangential force brought by the rotation of the slide are superimposed and finally transformed into an upward rotational force along the stripping groove. This causes the rice to contact the stripping groove in a rotating posture, realizing the rapid tearing of the rice husk. The rice husk and small debris produced by dehulling float upward in the water environment due to buoyancy. Since there is a preset distance between two adjacent slide rings, the floating path will not be blocked by the slide below or above, and the separation space is greatly expanded. Larger foreign objects are separated from the rice by the screen before entering the spiral channel. When small particles of impurities fall through the sliding plate screening holes during the dehulling process, the preset distance between adjacent slide rings also provides an independent falling channel. Impurities will not bounce into the next slide ring due to the dense stacking of slide rings, but will fall directly into the bottom of the soaking tank, reducing the probability of impurities coming into contact with subsequent rice, thereby making the separation work more thorough.

[0019] like Figures 1-13 As shown, a rice processing soaking and dehulling device includes a dehulling tank body 1, which includes a soaking tank 101 and a collection tank 102. A sealing door is installed on the collection tank 102. A cylinder 2, fixed relative to the soaking tank 101, is installed in the soaking tank 101. A material cylinder 3, rotatably connected to the bottom of the cylinder 2, is connected to it. A slide 4 is fixedly connected to the outer side of the material cylinder 3. The slide 4 has a spiral continuous sliding structure. The slide plate 401 of the slide 4 has a continuous sliding curved surface for rice to slide. The extension trajectory of the sliding curved surface of the slide 4 is arranged in a multi-turn spiral pattern from top to bottom in the vertical direction, and a preset distance is maintained between adjacent spiral trajectories, so that the slide 4 forms a conical spiral sliding channel. The dehulling tank body 1 also includes a top frame 103, support legs, and two drain pipes. The top frame 103 and support legs... The material cylinder 3 is fixedly connected to the soaking tank 101 and the collection tank 102 respectively. Two drain pipes are connected to the soaking tank 101 and the collection tank 102 respectively. Each drain pipe is connected to a valve. One end of the cylinder 2 is fixedly connected to the top frame 103. A hydraulic rod 12 is fixedly installed in the shelling box body 1. A fixed block 13 is fixedly connected to the output end of the hydraulic rod 12. A push-pull plate 14 is fixedly connected to the outside of the material cylinder 3. The push-pull plate 14 has a groove. A fixed column 15 is slidably connected in the groove. The fixed column 15 is fixedly connected to the fixed block 13. The hydraulic rod 12 drives the material cylinder 3 to drive the slide 4 to rotate back and forth in a small amplitude through the cooperation of the fixed block 13, the fixed column 15 and the push-pull plate 14. During the rotation, the rice grains are broken up and the rice grains are made to come into full contact with the auxiliary plate 7 and the peeling groove 6, thereby improving the shelling effect. The slide 4 is immersed in water in the soaking tank 101. One end of the slide 4 is used for feeding, and the other end is connected to the feed cylinder 3. The bottom end of the feed cylinder 3 is rotatably connected to the discharge pipe 5, which is connected to the collection tank 102. The slide plate 401 of the slide 4 is provided with several peeling grooves 6 distributed along its spiral trajectory. Several screening holes 11 are opened inside the slide plate 401. The screening holes 11 and the peeling grooves 6 are distributed alternately. Small particles of foreign matter are screened out through the screening holes 11. The screening holes 11 and the peeling grooves 6 on the slide plate 401 are distributed alternately to simultaneously screen out small particles of foreign matter (such as mud, sand, and gravel) in the rice during the hulling process, preventing impurities from accumulating and reducing the probability of impurities mixing into the brown rice. Impurities are discharged directly from the slide 4 through the screening holes 11, without the need for additional impurity removal process, shortening the processing time. In the process flow, several auxiliary plates 7 are slidably installed in the slide rail 4. Each auxiliary plate 7 includes a short plate 701 and a long plate 702, forming a figure-eight shape and fitting snugly against the slide rail 4. The auxiliary plate 7 also includes a crossbar 703, which is fixedly installed between the short plate 701 and the long plate 702, maintaining their relative positions. The crossbar 703 fixes the relative positions of the short plate 701 and the long plate 702, ensuring a stable angled structure for the figure-eight auxiliary plate 7. This allows rice to pass through the gaps between the short plate 701 and the long plate 702, preventing misalignment of the plates due to paddy compression during the hulling process. The cylinder 2 is equipped with several sets of slide rails 8, each set of which is slidably connected to a connecting frame 9. Each connecting frame 9 is slidably connected to an "L"-shaped sliding rod 10. One end of each sliding rod 10 is fixedly connected to a nearby crossbar 703, and the other end of each sliding rod 10 has a "U"-shaped protrusion. The protrusion of the sliding rod 10 is slidably connected to the connecting frame 9, ensuring that the sliding rod 10 can move linearly with the auxiliary plate 7. To address the issue of positional interference between the auxiliary plate 7 and the slide rail 4 during rotation, the cooperative structure of the slide rail 8, connecting frame 9, and "L"-shaped sliding rod 10 enables adaptive adjustment of the lateral and longitudinal positions of the auxiliary plate 7. The connecting frame 9 slides along the slide rail 8 of the cylinder 2 and can move longitudinally together with the auxiliary plate 7, allowing the auxiliary plate 7 to adapt to the radial position changes during the rotation of the slide rail 4. The "U"-shaped protrusion of the sliding rod 10... The protrusion is slidably connected to the connecting frame 9, which can realize the lateral fine adjustment of the auxiliary plate 7 to match the arc change of the spiral trajectory of the slide 4, and achieve the purpose of adaptive adjustment of bidirectional displacement. This effectively avoids the phenomenon of jamming and interference between the auxiliary plate 7 and the inner wall of the slide 4 when the slide 4 rotates, ensuring the smooth rotation of the slide 4 and the continuity of the hulling operation. The slide 4 also includes a sliding shell 402. The cross section of the sliding shell 402 has an inclined structure. The sliding shell 402 has a spiral opening 403. Floating objects in the slide 4 can float out from the opening 403. One end of the sliding rod 10 is slidably connected to the opening 403. The buoyancy of the water is used to make the rice husks produced during hulling float up quickly and be discharged from the opening 403, realizing the real-time separation of rice husks and brown rice, and avoiding the accumulation of rice husks that affect the hulling efficiency or mix with brown rice.The sliding rod 10 is slidably connected to the opening 403, which neither hinders the floating of the rice husks nor hinders the stable support of the auxiliary plate 7. The cross-sections of one end of both the short plate 701 and the long plate 702 are arc-shaped and contact the inner wall of the sliding shell 402. The arc-shaped cross-sections of one end of the short plate 701 and the long plate 702 fit snugly against the inner wall of the sliding shell 402, reducing frictional wear between the plates and the sliding track 4.

[0020] The spiral conical slide 4 is immersed in water. As the rice spirals down the curved surface, it comes into contact with the stripping groove 6 and the auxiliary plate 7. With the help of hydraulic buffering, it achieves gentle dehulling and reduces the broken rice rate. The slide 4 is connected to the feed cylinder 3 and the discharge pipe 5. After dehulling, the brown rice is directly introduced into the collection tank 102. The rice husk floats and separates with the water flow, eliminating the need for additional air separation and screening equipment and solving the problem of rice husk powder mixing. The spiral structure of the slide 4 extends the residence time of the rice in the slide 4, which can fully dehull the rice.

[0021] A detachable annular material box 17 is installed on the top frame 103. The bottom of the material box 17 is connected to a detachable telescopic tube 18. One end of the telescopic tube 18 is fixed inside the slide rail 4. The telescopic tube 18 is a flexible hose that can adapt to the reciprocating rotation of the slide rail 4 to ensure continuous and smooth feeding. A detachable screen 19 is installed inside the material box 17. The screen 19 is used to block larger foreign objects. The detachable material box 17 and the screen 19 can quickly clean up large foreign objects (such as straw and stones) to prevent foreign objects from entering the slide rail 4 and causing equipment wear or shell failure. The detachable telescopic tube 18 (flexible hose) adapts to the rotation of the slide rail 4 to ensure smooth feeding.

[0022] An aeration pipe 16 is fixedly connected to the main body 1 of the hulling box. The aeration pipe 16 is equipped with a one-way valve. One end of the aeration pipe 16 is connected to the discharge pipe 5. The aeration pipe 16 is used to intermittently spray air upwards, which creates airflow disturbance in the discharge pipe 5 and the cylinder 2. On the one hand, it prevents the brown rice from sticking and blocking the discharge channel due to its high moisture content. On the other hand, it further separates the small rice husk fragments remaining on the surface of the brown rice. With the synergistic effect of airflow and water flow, the separation is improved. The one-way valve prevents wastewater backflow, ensures the stability of air spray, and further optimizes the hulling and separation effect.

[0023] In use, the rice to be processed is put into the annular feed box 17 on the top frame 103. The screen 19 in the feed box 17 first blocks large foreign objects, such as straw and large stones. After screening, the rice is conveyed to the feeding end of the spiral conical slide 4 through the telescopic pipe 18. It should be noted that the soaking tank 101 needs to be filled with clean water so that the spiral conical slide 4 is completely submerged in water. After the rice enters the slide 4, it spirals down from top to bottom along the sliding surface. During the descent, water absorption and softening are completed simultaneously. At the same time, the hydraulic rod 12 in the hulling box body 1 is activated, which is connected to the fixing block 13 and the fixing column. 15 drives the push-pull plate 14 to reciprocate, thereby causing the material cylinder 3 and the slide rail 4 to rotate slightly. During the rotation, the rice tumbles in the slide rail 4, avoiding uneven water absorption caused by accumulation. The rice is in continuous contact with the peeling groove 6 on the slide plate 401 of the slide rail 4, and is guided by the flexible clamping action of the "eight"-shaped auxiliary plate 7. The rice husk is gradually torn and peeled off. During this process, the slide rail 8, connecting frame 9 and "L"-shaped slide rod 10 on the cylinder 2 cooperate to drive the auxiliary plate 7 to make adaptive displacement in the lateral and longitudinal directions as the slide rail 4 rotates, always maintaining a close fit with the inner wall of the slide rail 4. To avoid positional interference, the rice husks produced during hulling, being less dense than water, float under the buoyancy of the water flow and collect along the inclined structure of the sliding shell 402 to be discharged at the spiral opening 403, achieving real-time separation of the rice husks and brown rice. Impurities in the rice, such as mud, sand, and small particles of gravel, are directly screened out through the screening holes 11 on the sliding plate 401 during the descent and fall to the bottom of the soaking tank 101 without the need for additional impurity removal equipment. The hulled brown rice enters the feed cylinder 3 connected to it along the slide 4, and is then conveyed to the collection tank 102 through the discharge pipe 5. During the conveying process, the aeration pipe 16 connected to the discharge pipe 5 is intermittently aerated. The air is sprayed upwards. It should be noted that the outer end of the aeration pipe 16 can be connected to an external air compressor, which intermittently supplies air to the aeration pipe 16. The airflow creates turbulence in the discharge pipe 5 and the cylinder 2, which on the one hand prevents the high moisture content brown rice from sticking and clogging the channel, and on the other hand blows away the small rice husk fragments remaining on the surface of the brown rice. The rice husk fragments will float on the water surface in the cylinder 2. The one-way valve on the aeration pipe 16 can effectively prevent wastewater from backflow. Finally, the brown rice falls into the collection tank 102, and the wastewater in the soaking tank 101 and the collection tank 102 can be discharged as needed through their respective drain pipes and valves.

[0024] It should be noted that the rice husks and small debris produced during hulling float upwards in the water environment due to buoyancy. Since there is a preset distance between adjacent sliding tracks 4 (rather than being tightly fitted), the floating path will not be blocked by the sliding tracks 4 below or above, and the separation space is greatly expanded. If a spiral sliding track 4 without spacing is used (the rice husks are easily intercepted by the adjacent sliding tracks 4 when floating and re-adhere to the surface of the sliding rice), the rice husk debris in this sliding track 4 can float smoothly upwards along the spacing space to the opening 403 of the sliding shell 402 for discharge, reducing the probability of cross-track adhesion and avoiding interference from the separated rice husk debris to the subsequent hulling process. As for small particles, when small particles fall through the screening holes 11 of the sliding plate 401 during the hulling process, the preset distance between adjacent sliding tracks 4 also provides an independent falling channel. The impurities will not bounce into the next sliding track 4 due to the dense stacking of sliding tracks 4, but will fall directly into the bottom of the soaking tank 101, reducing the probability of impurities coming into contact with the subsequent rice and improving the purity of the brown rice after hulling.

[0025] When the spiral conical slide 4 reciprocates in small amplitudes synchronously with the feed cylinder 3, its continuous sliding surface and spiral trajectory structure can generate an upward rotational force on the rice. That is, when the slide 4 rotates, the continuous sliding surface of the slide plate 401 does not simply drive the rice to make circular motion, but combines the downward spiral trajectory to form a compound force of downward sliding and upward rotation on the rice. The inertia of the rice sliding down the surface and the tangential force brought by the rotation of the slide 4 are superimposed and finally transformed into an upward rotational force along the direction of the stripping groove 6, so that the rice contacts the stripping groove 6 in a rotating posture. If the rice is dehulled by relying solely on the friction generated by its own weight sliding down, the force is singular and the strength is limited. Some rice husks are difficult to peel off because they are too tightly attached to the brown rice. The upward rotational force can cause the rice to roll and misalign slightly at the stripping groove 6, and the scraping force of the stripping groove 6 can be increased. The friction force can precisely target the weak points of the bonding layer, achieving rapid tearing of the rice husk. It should be noted that when the rice slids down the curved surface in the spiral slide 4, it is prone to slippage or insufficient force due to only one-way contact with the peeling groove 6. However, the angled structure of the "eight"-shaped auxiliary plate 7 can form a two-way flexible clamp on the rice, guiding it to contact the peeling groove 6. At the same time, the inertia of the rice sliding down generates a scraping force through the relative movement of the plate and the rice, tearing the bonding layer between the rice husk and the brown rice. If the rice accumulates in the spiral slide 4, it will lead to uneven local force and affect the dehulling effect. The inclined surface of the "eight"-shaped auxiliary plate 7 can guide the rice to slide down the predetermined trajectory in an orderly manner. Moreover, when the slide 4 rotates, the auxiliary plate 7 can also push the rice to contact the peeling groove 6 and carry out the dehulling work.
