Description

Technical Field

[0001] This invention relates to the field of rice drying technology, specifically to a wet rice processing and drying equipment and method. Background Technology

[0002] Paddy rice refers to the grains of rice without the husk removed. Before processing, paddy rice contains a certain amount of moisture, generally around 12-15%. This moisture content varies depending on the season and variety of rice. Moisture is a chemical component of paddy rice, and its level significantly impacts rice processing. High moisture content reduces the flowability of the paddy rice, making cleaning and grain separation difficult, reducing dehulling efficiency, decreasing processing intensity, increasing broken rice rate, and leading to higher energy consumption and production costs. Conversely, while low moisture content facilitates dehulling, the tight bond between the bran and endosperm makes grinding difficult, also hindering processing. The optimal processing moisture content for paddy rice is 13.5%-15%, thus requiring the use of a dryer to dry the wet paddy rice during processing.

[0003] Existing drying equipment mainly consists of three parts: dryer, conveying mechanism and heat pump. During the drying process, the drying speed and temperature of rice need to be controlled to prevent the rice from cracking during the drying process. "Cracking" refers to the formation of micro-cracks on the surface of rice grains after drying or cooling, which directly affects the broken rice rate during rice milling, thus affecting the rice yield.

[0004] However, in actual operation, although the rice undergoes screening to remove impurities before drying, some impurities (such as stones) may remain mixed in due to their small size and not be removed by the screening mechanism. Consequently, when this part of the rice containing impurities is dried in the dryer, it can easily cause the machine to become clogged or jammed during operation. This affects the drying efficiency of the rice and reduces the service life of the dryer. Therefore, we propose a wet rice processing and drying equipment and method. Summary of the Invention

[0005] The purpose of this invention is to provide a wet grain processing and drying equipment and method to solve the problems mentioned in the background art.

[0009] Preferably, a hot air duct is provided in the A processing area, and an air inlet pipe is provided in the A processing area near the B processing area. A strip filter is provided in the inner wall of the A processing area, and the pore size of the strip filter is smaller than the size of the rice grain.

[0010] Preferably, the screening component includes a conveyor plate disposed within the B processing area, and the B processing area has a slot inside, wherein one end of the conveyor plate is located inside the slot, wherein multiple fixing blocks are disposed at both ends of the conveyor plate, and elastic sheets are connected between the fixing blocks and the inner wall of the B processing area, wherein a connecting column is disposed on the conveyor plate, a trough is disposed inside the B processing area, and the trough is located below the slot, and an impurity conveying port is disposed at the end of the B processing area, and the conveyor plate is located inside the impurity conveying port.

[0011] Preferably, the B processing area is provided with a rotating shaft that is rotatably connected to its inner wall, and the two ends of the rotating shaft are located outside the B processing area and inside the tank, respectively. A rotating plate is installed at the end of the rotating shaft inside the tank, and an actuating rod is connected between the end of the rotating plate and the connecting column. Both ends of the actuating rod are rotatably connected to the ends of the rotating plate and the connecting column.

[0012] Preferably, a motor is fixedly installed at the bottom of the B processing area, and the output end of the motor penetrates through the inner wall of the B processing area and extends into its interior. A circular turntable is provided on the output end of the motor, wherein an annular slide rail is provided on the circular turntable, and filter holes are provided on the circular turntable, the annular slide rail and the conveyor plate.

[0013] Preferably, the power assembly includes a second motor mounted on the feed hopper, wherein the output end, shaft and rotating shaft end of the second motor are all equipped with chain wheels, and the chain wheels are connected to each other by a chain.

[0014] Preferably, the A processing area is provided with multiple baffles, and a baffle that is rotatably connected to the baffle is provided on the inner wall of the A processing area. The side wall of the baffle is provided with a hinge rod, and an arc-shaped force-bearing panel is installed at the end of the hinge rod. A rotating shaft is installed at the end of one of the spiral stirring rods, and a cam is installed on the rotating shaft.

[0015] A method of using a wet grain processing and drying device includes the following steps:

[0016] S1. Rice is fed from the inlet end of the feed hopper and enters the A processing area after passing through the feed area;

[0017] S2. The rice enters the A processing area and passes through the baffle and the barrier in sequence. Hot air is introduced through the hot air duct and the second motor is started. The motor is driven by the chain wheel and the chain on it. The shaft, the ring gear, the meshing gear, the through column and the spiral stirring rod rotate synchronously. The spiral stirring rod acts on the barrier through the rotating shaft, the cam, the arc-shaped force-bearing panel and the hinge rod. The spiral stirring rod acts on the rice, and the soil inside falls off in bulk.

[0018] S3. Air is introduced through the air inlet pipe to disperse the rice grains. During the conveying process, the strip filter screen filters out the soil inside the rice grains.

[0019] S4. The rotating shaft moves synchronously with the motor under the action of the chain wheel. Under the action of the rotating plate, the action rod, the connecting column and the elastic plate, the conveying plate vibrates. Under the action of the filter holes, the rice falls onto the circular turntable and the stones are discharged along the impurity conveying port.

[0020] S5. The circular turntable rotates under the action of motor one. Based on the difference in gravity between the stones and the rice, centrifugal force is used to screen out some of the stones that have not been intercepted by the filter holes and have fallen onto the circular turntable. The rice enters the feed end of the dryer body from the discharge end of processing area B. The dryer body is started to dry the rice. Completed.

[0021] Compared with the prior art, the beneficial effects of the present invention are:

[0022] 1. This invention utilizes a conveyor plate and its filter holes to screen out solid impurities such as stones mixed in with the rice. Under the action of a circular turntable, centrifugal force is used to screen the rice again, thereby effectively ensuring that the rice entering the dryer body is free of solid impurities. At the same time, the spiral stirring rod can break up the soil mixed in with the rice, which is convenient for subsequent conveying to the strip filter screen for screening. This effectively prevents soil from entering the dryer body with the rice. Through the design of this invention, impurities can be effectively prevented from affecting the normal operation of the dryer body.

[0023] 2. This invention utilizes baffles to disperse the neatly flowing wet grains into processing area A. A rotating shaft transmits power from the spiral stirring rod to a cam, causing it to rotate. The cam's rotation acts on an arc-shaped force-bearing panel, causing the hinged rod to drive the baffle to further disperse the wet grains in processing area A. Simultaneously, it exposes the soil mixed within the grains to the air outlet of the air inlet pipe, preventing soil from entering the dryer body and ensuring both efficiency and improved processing quality.

[0024] 3. This invention utilizes a conveyor plate and its filter holes to screen out impurities such as stones contained in wet grains. The conveyor plate is made to shake during screening using the filter holes by a rotating shaft, rotating plate, and actuating rod, thereby achieving rapid screening. At the same time, a circular turntable and its annular slide rail and filter holes are used to perform secondary screening of impurities, preventing excessive impurities in the wet grains from entering the dryer body and damaging its internal components, and improving the overall quality of the drying process.

Detailed Implementation

[0040] 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.

[0041] Please see Figure 1-14This invention provides a technical solution: a wet rice processing and drying equipment and method. This invention addresses the problems mentioned in the background art. During the drying process, some impurities (such as stones) easily mix with the rice and enter the dryer. When this rice containing impurities is dried in the dryer, it can easily cause blockages or jamming during operation, affecting the drying efficiency and service life of the rice. This invention addresses this problem by making corresponding improvements, including a dryer body 1 and a support body 2 installed on one side of the dryer body 1. A feeding hopper 3 is fixedly installed on the support body 2, and the discharge end of the feeding hopper 3 is connected to the inlet end of the dryer body 1. The feeding hopper 3 is connected to the inlet end of the dryer body 1. The system comprises three treatment zones: Zone 31, Zone A (32), and Zone B (33). Further explanation is needed because the rice may contain impurities such as soil. Since undried rice retains some moisture on its surface, the soil mixed in may be clump-like. To prevent this soil from affecting the drying process, Zone A (32) is used to treat the soil. Two hot air ducts 418 are fixedly installed in Zone A (32). Hot air is supplied to Zone A (32) through these ducts. This hot air preheats the rice and effectively dries the soil, facilitating subsequent sieving. A [unclear - possibly a device or equipment] is installed near Zone B (33) in Zone A (32). The air inlet duct 419 has a strip filter 410 installed on the inner wall of the A processing area 32. The pore size of the strip filter 410 is smaller than that of the rice grains. To further explain, when the rice grains move to the strip filter 410, they are at the inlet of the air inlet duct 419. The airflow within the air inlet duct 419 disperses the rice grains (while they are still in transport), exposing the dried soil inside to the strip filter 410, which removes the soil. The feed hopper 3 is also equipped with an auxiliary removal unit 4 for removing impurities from the rice grains. This auxiliary removal unit 4 includes a pretreatment component 41, a screening component 42, and a power component 43. The pretreatment component 41 is located inside the A processing area 32 and its main function is... The rice is initially broken up, exposing the soil to hot air. At the same time, it acts on the soil to make contact with the inner wall of the A treatment area 32, breaking it into small pieces of soil, which are convenient for subsequent filtration at the strip filter screen 410. The screening component 42 is set in the B treatment area 33, which is mainly used to remove stones from the rice to prevent them from affecting the dryer body 1 when they enter the dryer body 1. The power component 43 is set on the feed hopper 3, which is mainly used to provide power to the pretreatment component 41 and the screening component 42. Further, the A treatment area 32 of the present invention can be appropriately equipped with a buffer layer to prevent the rice from being broken by impact force when the pretreatment component 41 is working.

[0042] Specifically, the staff pours the rice into the feeding area 31, and the rice enters the A processing area 32 through the feeding area 31. When entering the A processing area 32, the hot air from the hot air duct 418 dries the rice and the soil inside (the rice has a high moisture content and is in a pre-drying state). The pre-treatment component 41 is used to break up the rice, exposing the soil inside to the environment, and breaking up lumps of soil into smaller pieces. When the rice is transported to the strip filter screen 410, which is at the opening of the air inlet pipe 419, the rice is blown apart again through the air inlet pipe 419, and the soil flows out through the strip filter screen 410. When the rice is transported to the B processing area 33, the screening component 42 removes stones from the rice, thereby effectively preventing impurities from entering the dryer body 1 and affecting the rice drying process.

[0043] As a further definition of the auxiliary removal unit 4 of the present invention, the pretreatment assembly 41 includes a circular sleeve 411 disposed inside the A treatment area 32, and a fixing rod 412 for fixed connection with the inner wall of the A treatment area 32 is symmetrically installed at the end of the circular sleeve 411. A shaft 413 for rotatable connection with its inner wall is installed inside the circular sleeve 411, and one end of the shaft 413 penetrates the inner wall of the A treatment area 32 and extends to the outside. An annular toothed row 414 is installed at the other end of the shaft 413, and the annular toothed row 414 is located inside the circular sleeve 411. Figure 1-4 It is known that processing area A 32 has a vertically downward region, and the circular sleeve 411 in this invention is located in this vertically downward region. The circular sleeve 411 is provided with multiple meshing gears 415 inside. To be further explained, there are four meshing gears 415 in this invention. The specific number can be designed according to the actual working conditions. The meshing gears 415 are meshed with the annular tooth row 414. A through column 416 for rotatably connecting the inner wall of the circular sleeve 411 is fixedly installed on the meshing gears 415. The end of the through column 416 penetrates the inner wall of the circular sleeve 411 and extends to the outside. A spiral stirring rod 417 is fixedly installed at the end of the through column 416. It should be noted that the spiral stirring rod 417 is connected to the through column 416 by bolts. The spiral stirring rod 417 is located on the rice conveying path.

[0044] As a further extension of the auxiliary removal unit 4 of the present invention, in order to fully expose the soil in the wet rice to the A treatment area 32, the present invention has fixedly installed multiple baffles 45 at the feed end of the A treatment area 32. When the amount of wet rice is large, the spiral stirring rod 417 cannot effectively disperse the wet rice and the soil in it, and some soil may still remain in the wet rice. Therefore, the baffles 45 can disperse the neatly flowing rice to the air inlet of the hot air duct 418. At the same time, a baffle 451 for rotating connection with its inner wall is installed inside the A treatment area 32. Further, a column and a torsion spring are installed between the baffle 451 and the inner wall of the A treatment area 32 for connection (since the column and torsion spring are existing technologies, the present invention does not describe them in detail). A hinge rod 452 is fixedly installed on one side of the baffle 451. Figure 3 , 4 As shown in section 14, a rotating shaft 453 is installed at the end of one of the spiral stirring rods 417, and the end of the rotating shaft 453 is rotatably connected to the inner wall of the A treatment area 32. A cam 454 is fixedly installed on the rotating shaft 453. The end of the hinge rod 452 is close to the cam 454 and an arc-shaped force-bearing panel 455 is fixedly installed on it. When the cam 454 rotates with the rotating shaft 453, the protruding part of the cam 454 will act on the arc-shaped force-bearing panel 455, causing it to drive the baffle 451 to deflect at a small angle. This causes the end of the baffle 451 (i.e., the part in contact with the wet grain) to act on the wet grain, breaking it up. This allows the spiral stirring rod 417 to effectively and quickly break up the wet grain when it moves to the spiral stirring rod 417, exposing the soil inside to the environment.

[0045] Specifically, as described further as the pretreatment component 41 of this invention: when the rice enters treatment area A 32, the shaft 413 rotates under the action of the power component 43. At this time, one end of the shaft 413 is located inside the circular sleeve 411, and the annular gear rack 414 installed on it rotates synchronously to drive the through column 416 to rotate under the action of the meshing gear 415. Since the through column 416 and the spiral stirring rod 417 are connected by bolts, the spiral stirring rod 417 then breaks up the rice during transportation, exposing the soil in the rice. When the rice enters the A treatment area 32, the hot air blown by the hot air duct 418 dries the soil. When the soil enters the strip filter 410, the soil mixed with the rice is exposed to the environment again by the air inlet duct 419 and flows to the outside through the strip filter 410. Since the soil is in a relatively dry state at this time, there is less sticky soil on the strip filter 410, which can prevent the soil from sticking to the strip filter 410.

[0046] As a further definition of the auxiliary removal unit 4 of the present invention, the screening component 42 includes a conveyor plate 421 installed in the B processing area 33. When rice flows from the A processing area 32 into the B processing area 33, the rice falls onto the conveyor plate 421. The B processing area 33 has a slot 422 inside, with one end of the conveyor plate 421 located inside the slot 422. An impurity conveying port 427 is installed at the end of the B processing area 33, and the conveyor plate 421 is located inside the impurity conveying port 427. Multiple fixing blocks 423 are fixedly installed at both ends of the conveyor plate 421, and elastic sheets 424 are connected between the fixing blocks 423 and the inner wall of the B processing area 33. A connecting post 425 is installed on the conveyor plate 421. A trough 426 is provided inside the B processing area 33, and the trough 426 is located below the slot 422. In the B processing area 33, a rotating shaft 428 is installed inside and rotates to be connected to its inner wall. The two ends of the rotating shaft 428 are located outside the B processing area 33 and inside the tank 426, respectively. As a further definition of the auxiliary removal unit 4 of the present invention, the power assembly 43 includes a second motor 431 fixedly installed on the feed bin 3. The output end of the second motor 431, the shaft 413 and the end of the rotating shaft 428 are all equipped with chain wheels 432, and the chain wheels 432 are connected to each other by a chain. A rotating plate 429 is fixedly installed at one end of the rotating shaft 428 inside the tank 426 (the other end where the chain wheel 432 is installed). An actuating rod 420 is connected between the end of the rotating plate 429 and the connecting column 425, and both ends of the actuating rod 420 are rotated to be connected to the ends of the rotating plate 429 and the connecting column 425.So that when the rotating shaft 428 rotates synchronously with the motor 431 under the action of the chain wheel 432, the rotating shaft 428 drives the rotating plate 429 at the end to rotate, so that under the action of the rod 420, the connecting column 425 and the conveying plate 421 on it are pulled and pushed to perform reciprocating motion (i.e., vibration). The bottom of the B processing area 33 is fixedly installed with the motor 441, and the output end of the motor 441 penetrates through the inner wall of the B processing area 33 and extends into its interior. A circular turntable 442 is fixedly installed on the output end of the motor 441. It should be noted that the circular turntable 442 and the inner wall of the B processing area 33 are... The system is connected by a rotating mechanism. A circular slide rail 443 is mounted on the circular turntable 442, and the circular slide rail 443 is installed on the outer ring of the circular turntable 442. Filter holes 444 are provided on the circular turntable 442, the circular slide rail 443, and the conveyor plate 421. To further explain, the aperture size of the filter holes 444 is larger than the size of the rice grains, allowing the rice grains to pass through the filter holes 444. However, the size of the filter holes 444 is smaller than the size of the pebbles. It should be noted that because the conveyor plate 421 and its filter holes 444 are used to first screen the rice grains for pebbles, resulting in a larger screening volume, pebbles may sometimes remain and block the filter holes 444. Then, under the influence of vibration, the rice grains either return to the conveyor plate 421 or fall below it (i.e., onto the circular turntable 442). Over time, the filter holes 444 on the conveyor plate 421 may enlarge, allowing some stones to pass through. To further explain, the filter holes 444 on the circular turntable 442 are slightly smaller than those on the conveyor plate 421, but they can still filter the rice grains. When the rice grains fall onto the circular turntable 442, the motor 441 starts, causing the turntable 442 to rotate. During rotation, the rice grains fall along the filter holes 444 on the turntable 442. The rice grains fall onto the inner wall of processing area 33 (B). If there are stones, they will rotate on the circular turntable 442. During the rotation, both the rice grains and the stones will be subjected to centrifugal force. According to the centrifugal force formula F=mv2 / r, since the mass of the stones is generally greater than that of a single grain of rice, the stones will move outward (towards the annular slide rail 443). As a result, the stones will eventually be stored in the annular slide rail 443, while the rice grains will fall through the filter holes 444 onto the inner wall of processing area 33 (B) and be transported to the feed end of the dryer body 1. To further explain, the staff needs to clean the stones on the annular slide rail 443 regularly.

[0047] Specifically, when the rice is transported from processing area A 32 to processing area B 33, the rice is on the conveyor plate 421. The motor 431 drives the rotating shaft 428 to rotate via the chain wheel 432, so that the rotating shaft 428 drives the rotating plate 429 at its end to move synchronously. Under the action of the rod 420, the connecting column 425 drives the conveyor plate 421 on it to move back and forth. Under the action of the force, the rice on the conveyor plate 421 falls through the filter hole 444 onto the circular turntable 442, while the stones in the rice enter the impurity conveying port 427 through the force and are discharged. The rice grains fall onto the circular turntable 442 and are directed to the outside. At this time, the motor 441 starts and drives the circular turntable 442 to rotate through its output end. During the rotation, the rice grains fall through the filter holes 444 onto the inner wall of the B processing area 33 and enter the feed end of the dryer body 1 along its surface. If there are stones in the rice grains, they will move to the annular slide rail 443 for collection under the action of centrifugal force, so as to further process the rice grains. Thus, through the structural design of the present invention, the rice grains can be effectively screened, preventing rice grains containing impurities from entering the dryer body 1 and ensuring the drying quality of the rice grains.

[0048] A method of using a wet grain processing and drying device includes the following steps:

[0049] S1. Rice is fed from the inlet end of the feed hopper 3, passes through the feed area 31 and enters the A processing area 32;

[0050] S2. The rice enters the A processing area 32 and passes through the baffle 45 and the baffle 451 in sequence. Hot air is introduced through the hot air duct 418, and the motor 431 is started. The transmission is carried out through the chain wheel 432 and the chain on it. The shaft 413, the ring gear 414, the meshing gear 415, the through column 416 and the spiral stirring rod 417 rotate synchronously. The spiral stirring rod 417 acts on the baffle 451 through the rotating shaft 453, the cam 454, the arc-shaped force-bearing panel 455 and the hinge rod 452. The spiral stirring rod 417 acts on the rice, and the soil inside falls off in bulk.

[0051] S3, air intake pipe 419 intakes air to blow away the rice grains. During transportation, strip filter screen 410 filters the soil in the rice grains.

[0052] S4. The rotating shaft 428 moves synchronously with the motor 431 under the action of the chain wheel 432. Under the action of the rotating plate 429, the action rod 420, the connecting column 425 and the elastic plate 424, the conveying plate 421 vibrates. Under the action of the filter hole 444, the rice falls onto the circular turntable 442 and the stones are discharged along the impurity conveying port 427.

[0053] S5. The circular turntable 442 rotates under the action of motor 441. According to the difference in gravity between the stones and the rice, centrifugal force is used to screen out some of the stones that were not intercepted by the filter holes 444 and fell onto the circular turntable 442. The rice enters the feed end of the dryer body 1 from the discharge end of the B processing area 33. The dryer body 1 is started to dry the rice.
