Description

Technical Field

[0001] This invention relates to the field of grain drying technology, and in particular to a drying device for rice processing. Background Technology

[0002] Rice drying is a key process in rice processing, and its quality and efficiency directly determine the subsequent processing quality, storage stability, and production benefits of rice.

[0003] Currently, most existing drying equipment uses a fixed-parameter drying mode, where the ranges of the drying and tempering sections are fixed and cannot be adjusted. This makes it impossible to dynamically adjust drying parameters based on real-time changes in the moisture content of the rice during the drying process. Furthermore, rice drying has a defined temperature threshold, and the drying intensity cannot be adjusted by directly increasing the drying temperature. This leads to over-drying or incomplete drying of rice with different initial moisture levels and from different batches, severely affecting drying uniformity and rice quality. In addition, the tempering process, a core step in balancing the moisture content inside and outside the rice and preventing grain cracking, is often fixed in existing drying equipment, lacking a dynamic adjustment mechanism linked to the degree of drying. In actual production, the required tempering time varies significantly between different batches and with different initial moisture contents. A fixed tempering time easily leads to two extreme problems: first, insufficient tempering time results in an imbalance of moisture inside and outside the rice, making it prone to grain breakage and cracking during subsequent processing; second, redundant tempering time leads to a significant extension of the rice drying cycle, wasting tempering time and significantly reducing overall drying efficiency.

[0004] Therefore, there is an urgent need to provide a drying device that can accurately adapt to changes in rice moisture content, optimize drying and tempering effects, and thus improve the quality and efficiency of rice drying. Summary of the Invention

[0005] Therefore, it is necessary to provide a drying device for rice processing, which aims to solve the technical problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a drying device for rice processing, comprising a feeding unit, a discharging unit, and a hot air unit.

[0007] The rice processing drying device also includes a drying unit. At least two drying units are provided and located between the feeding unit and the discharging unit. The two drying units are detachably connected. The drying unit includes two compensation parts distributed vertically. Multiple sets of air intake guide groups are arranged from top to bottom in the compensation parts. An exhaust guide group is provided below each set of air intake guide groups. An adjustment part is provided on both the air intake guide group and the exhaust guide group.

[0008] The compensation unit includes a compensation frame, with detection components installed at both the top and bottom ends of the compensation frame, and gas collection frames installed at both the left and right ends of the compensation frame.

[0009] The structure of the intake guide group is the same as that of the exhaust guide group and is symmetrical from left to right. The intake guide group includes multiple guide plates that are evenly installed in the compensation frame from front to back. A vent hole is provided at the right end of the guide plate on the frame wall of the compensation frame.

[0010] The adjustment unit includes multiple movable rods disposed below the corresponding guide plate. Multiple adjustment components are provided on the movable rods. The ends of the multiple movable rods slide through the corresponding vent holes and are jointly mounted on a connecting plate. At least two driving components are installed between the connecting plate and the corresponding air collection frame.

[0011] When the detection device detects the moisture content of the rice, if the detection difference is small, the corresponding drive component moves the connecting plate to open a corresponding number of ventilation holes to facilitate the entry of hot air and increase the drying time. If the detection difference is large, the drive component further moves the connecting plate, and the spacing between the guide plates is changed by the moving rod and the adjusting component to adjust the flow speed of the rice and further increase the drying time. Similarly, the resting time of the rice is changed by controlling the closure of the ventilation holes.

[0012] Preferably, the drying unit further includes a drying section and a tempering section that are detachably installed on the upper end of the upper compensation frame and the upper end of the lower compensation frame, respectively. The drying section, the tempering section and the two compensation frames are detachably connected to each other. The drying section and the two compensation sections are connected to an air intake section and an exhaust section.

[0013] Preferably, the drying section includes a drying frame, in which a plurality of guide plates are evenly distributed from top to bottom and staggered from left to right. Each guide plate has a flow hole at its end. The flow holes at the ends of adjacent guide plates are staggered left and right. Sealing frames are installed on the left and right walls of the drying frame, and the two sealing frames are respectively connected to the plurality of corresponding flow holes.

[0014] Preferably, the easing section includes a detachable easing frame installed at the lower end of the compensation frame, and multiple guide plates are installed inside the easing frame, which are evenly distributed from top to bottom and staggered from left to right.

[0015] Preferably, the adjustment part further includes a sealing frame disposed on the outer periphery of the connecting plate. The sealing frame is installed on the outer frame wall of the compensation frame and communicates with the corresponding multiple vent holes. A sealing gasket is laid in the middle of the sealing frame.

[0016] Preferably, the air intake includes an air intake frame detachably connected to the hot air unit, and the air intake frame is detachably connected and communicated with the corresponding sealed frame and the two corresponding air collection frames through multiple connecting pipes.

[0017] Preferably, the exhaust section includes an exhaust pipe that is detachably connected to and communicates with the corresponding sealing frame and the two corresponding air collection frames, and an exhaust module is installed in the middle of the exhaust pipe.

[0018] Preferably, the detection component consists of a plurality of guide plates evenly installed from front to back on the inner wall of the compensation frame and a moisture detector installed on the inner side of the middle guide plate.

[0019] Preferably, the guide plate is composed of two rotating plates hinged together, and the two rotating plates are arranged in a cone shape with the hinge facing upward. The multiple guide plates of the intake guide plate group and the multiple guide plates of the exhaust guide plate group are staggered front and back.

[0020] Preferably, the adjusting component includes a cylindrical sleeve fitted onto the moving rod, with two symmetrically arranged lifting protrusions on the outer periphery of the cylindrical sleeve, and the two lifting protrusions are respectively installed on the inner sidewalls of the two rotating plates of the guide plate.

[0021] Preferably, the upper end of the drying frame located at the top is detachably connected to the feeding unit.

[0022] Preferably, the lower end of the compensation frame located at the bottom is detachably connected to the discharge unit.

[0023] Preferably, the feeding unit includes a connecting cover that is detachably installed at the top of the uppermost drying frame, and the connecting cover has a feeding hole in the middle.

[0024] Preferably, the discharge unit includes a discharge frame that is detachably installed at the lower end of the lowest compensation frame. The discharge frame has a discharge hole, a sealing valve is installed in the discharge hole, and a fixing seat is installed on the outer periphery of the discharge frame.

[0025] Preferably, the hot air unit includes two air inlet pipes that are detachably connected to the two air inlet frames, and the ends of the two air inlet pipes away from the two air inlet frames are connected to a hot air module.

[0026] In summary, the present invention has the following beneficial technical effects: 1. The compensation unit used in the present invention can flexibly switch between the drying area and the tempering area according to the moisture detection results of the rice. It can increase the drying time when the moisture content of the rice does not meet the standard, and can also extend the tempering time when needed, so as to ensure that the moisture content of the rice is uniform and the quality is good after drying, thereby improving the yield of the finished rice product in subsequent rice processing.

[0027] 2. The moisture detectors installed at both ends of the compensation frame in this invention can detect the surface and internal and external moisture content of the rice in real time, thereby adjusting the drying process. During the drying stage, when the detection difference is small, the control system controls the drive component to open a corresponding number of ventilation holes, increasing the drying time; when the detection difference is large, the drive component drives the adjustment component to change the spacing of the guide plates, reducing the flow speed of the rice and further extending the drying time to ensure the drying quality of the rice. During the tempering stage, the tempering time can also be flexibly adjusted by controlling the closure of the ventilation holes and the spacing of the guide plates. This can either increase the tempering time to ensure the tempering effect, or allow the next drying step to proceed directly after tempering, thereby effectively reducing the waiting time for rice tempering and improving the overall drying efficiency of the rice.

Detailed Implementation

[0044] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention can be practiced in many other ways not described herein, and those skilled in the art can make similar modifications without departing from the spirit of the invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0045] See Figures 1-3A rice drying device includes a feeding unit 1. The feeding unit 1 includes a connecting cover 10 with a feeding hole 11 in the middle. The feeding unit 1 is an existing rice feeding device. The connecting cover 10 is connected to an existing rice lifting bucket, and the feeding hole 11 is connected to a conveying pipe on the rice lifting bucket. The rice lifting bucket lifts the rice to the conveying pipe, and the rice enters the feeding hole 11 along the conveying pipe.

[0046] See Figures 1-5 The rice processing drying device also includes a discharge unit 2, which is an existing paddy discharge device. The discharge unit 2 includes a discharge frame 20 with a discharge hole 21. A sealing valve (not shown in the figure) is installed in the discharge hole 21. A fixing seat 22 is installed on the outer periphery of the discharge frame 20 and is fixedly installed on the ground. In the initial state, the sealing valve seals the discharge hole 21 to achieve the accumulation of paddy.

[0047] See Figure 1 , Figure 7 and Figure 9 The rice processing drying device also includes at least two drying units 4 located between the feeding unit 1 and the discharging unit 2. The two drying units 4 are detachably connected. Each drying unit 4 includes two compensation parts 40 distributed vertically. Each compensation part 40 includes a compensation frame 400. The lower end of the compensation frame 400 located at the bottom is detachably connected to the discharging unit 2. The discharging frame 20 is detachably installed at the lower end of the compensation frame 400 located at the bottom.

[0048] See Figure 1 , Figure 4 , Figure 5 and Figure 8 The drying unit 4 further includes a drying section 44 and a tempering section 45, which are detachably installed on the upper end of the upper compensation frame 400 and the upper end of the lower compensation frame 400, respectively. The drying section 44, the tempering section 45, and the two compensation frames 400 are detachably connected. The drying section 44 includes a drying frame 440, and the upper end of the uppermost drying frame 440 is detachably connected to the feeding unit 1. The tempering section 45 includes a tempering frame 450 detachably installed on the lower end of the compensation frame 400. The uppermost drying frame 440 is detachably connected to the connecting cover 10 by multiple bolts. The installation connection is as follows: the two drying frames 440, four compensation frames 400 and two tempering frames 450 between the connecting cover 10 and the discharge frame 20 are distributed from top to bottom as follows: drying frame 440-compensation frame 400-tempering frame 450-compensation frame 400-drying frame 440-compensation frame 400-tempering frame 450-compensation frame 400. The compensation frame 400 at the bottom is detachably connected to the discharge frame 20 by bolts. The two drying frames 440, four compensation frames 400 and two tempering frames 450 are all detachably connected by multiple bolts to form an integral silo frame.

[0049] In actual operation, the rice gradually enters the two drying frames 440, four compensation frames 400, two tempering frames 450 and discharge frame 20 through the feed hole 11, and gradually fills the silo frame.

[0050] See Figure 1 , Figure 4 , Figure 5 and Figure 8 The drying frame 440 is equipped with multiple guide plates 441 that are evenly distributed from top to bottom and staggered from left to right. Each guide plate 441 has a flow hole 442 at its end. The flow holes 442 at the ends of adjacent guide plates 441 are staggered from left to right. The left and right frame walls of the drying frame 440 are equipped with sealing frames 443, and the two sealing frames 443 are connected to the multiple corresponding flow holes 442 respectively. The compensation frame 400 is equipped with air collecting frames 401 at both ends.

[0051] See Figure 1 , Figure 5 and Figure 8 The drying section 44 and the two compensation sections 40 are connected to an air intake section 46. The air intake section 46 includes an air intake frame 460 that is detachably connected to the hot air unit 3. The air intake frame 460 is detachably connected and communicates with the corresponding sealing frame 443 and the two corresponding air collection frames 401 through multiple connecting pipes 461.

[0052] See Figure 1 , Figure 5 and Figure 8 The rice processing drying device also includes a hot air unit 3, which is an existing hot air device. The hot air unit 3 includes two air inlet pipes 31 that are detachably connected to two air inlet frames 460 respectively. The ends of the two air inlet pipes 31 away from the two air inlet frames 460 are connected to a hot air module 30. The hot air module 30 mainly consists of a hot air furnace and a hot air fan. The hot air module 30 is connected to the existing control system via an electrical signal.

[0053] In actual operation, multiple connecting pipes 461 are detachably connected to the corresponding sealed frame 443 and the two corresponding air collecting frames 401 by bolts. Then, the corresponding air inlet pipe 31 is detachably connected to the corresponding air inlet frame 460 by bolts. The control system controls the hot air module 30 to work. The hot air module 30 injects hot air into the air inlet pipe 31. The hot air enters the air inlet frame 460 through the air inlet pipe 31, and then enters the corresponding sealed frame 443 and the two corresponding air collecting frames 401 through multiple air inlet pipes 31. The hot air in the sealed frame 443 enters the drying frame 440 through multiple corresponding flow holes 442 and dries the rice in the drying frame 440.

[0054] See Figure 1 , Figure 5 and Figure 8 The drying section 44 and the two compensation sections 40 are also connected to an exhaust section 47. The exhaust section 47 is an existing dehumidification device. The exhaust section 47 includes an exhaust pipe 470 that is detachably connected and communicates with the corresponding sealing frame 443 and the two corresponding air collection frames 401. An exhaust module 471 is installed in the middle of the exhaust pipe 470. The exhaust module 471 is an existing dehumidification fan. The dehumidification fan is connected to the existing control system via an electrical signal.

[0055] In actual operation, the exhaust pipe 470 is detachably connected to the corresponding sealed frame 443 and the two corresponding air collection frames 401 by bolts. Then, the control system controls the exhaust module 471 to work. The exhaust module 471 draws air from the exhaust pipe 470 to create a negative pressure inside. The moisture generated by the hot air in the drying frame 440 drying the rice enters the sealed frame 443 connected to the exhaust pipe 470 through multiple corresponding flow holes 442. The moisture enters the exhaust pipe 470 through the sealed frame 443 and is discharged through the exhaust module 471.

[0056] See Figure 1 , Figure 5 , Figure 7 and Figure 9 The compensation frame 400 has detection components installed at both the upper and lower ends. The detection components consist of multiple guide plates 402 evenly installed from front to back on the inner wall of the compensation frame 400 and a moisture detector 403 installed on the inner side of the middle guide plate. The moisture detector 403 is an existing dual-band near-infrared moisture detection device and is electrically connected to the existing control system.

[0057] In specific operation, when the hot air module 30 and the exhaust module 471 are working, the sealing valve opens the discharge hole 21, and the rice in the silo frame is discharged from the discharge hole 21. At the same time, the rice feeding equipment continues to lift the rice to the conveying pipe. The rice enters the feed hole 11 along the conveying pipe to achieve continuous drying of the rice. Multiple guide plates 441 in the drying frame 440 disperse and guide the rice, so that the rice moves downward evenly and makes full contact with the hot air, which facilitates the drying of the rice. When the rice that has passed through the drying frame 440 falls to the multiple guide plates 402 on the compensation frame 400, the moisture detector 403 on the guide plate 402 detects the surface moisture of the rice.

[0058] See Figure 1 , Figure 5 , Figure 7 and Figure 9The compensation section 40 is provided with multiple sets of air intake guide groups 41 from top to bottom. Each set of air intake guide groups 41 is provided with an exhaust guide group 42 below it. The structure of the air intake guide group 41 is the same as that of the exhaust guide group 42 and is symmetrical from left to right. The air intake guide group 41 includes multiple guide plates 410 evenly installed from front to back in the compensation frame 400. The guide plate 410 is provided with a vent hole 411 on the frame wall of the compensation frame 400 at the right end.

[0059] See Figure 1 , Figure 6 , Figure 7 and Figure 9 Both the intake guide group 41 and the exhaust guide group 42 are provided with an adjustment part 43. The adjustment part 43 includes multiple moving rods 430 arranged below the corresponding guide plate 410. The ends of the multiple moving rods 430 slide through the corresponding vent holes 411 and are jointly installed with a connecting plate 431. At least two driving components 432 are installed between the connecting plate 431 and the corresponding air collection frame 401. The driving components 432 are existing displacement driving devices, specifically hydraulic push rods, electric push rods, electric sliders, etc. The driving components 432 are electrically connected to the existing control system.

[0060] See Figure 1 , Figure 7 and Figure 9 The adjustment part 43 also includes a sealing frame 433 disposed on the outer periphery of the connecting plate 431. The sealing frame 433 is installed on the outer frame wall of the compensation frame 400 and communicates with the corresponding multiple vent holes 411. A sealing gasket is laid in the middle of the sealing frame 433.

[0061] In practical operation, in the field of rice drying, to prevent the rice from bursting during drying, the moisture reduction in a single drying cycle is strictly controlled within 2%-3%. When the difference between the moisture content of the rice in the drying frame 440 and the initial moisture content is within 2%-3%, the standard is met. At this time, multiple drive components 432 restrict the connecting plate 431 within the sealing frame 433 and abut against the sealing gasket laid in the sealing frame 433, thereby sealing the multiple ventilation holes 411. At this time, there is no hot air circulation inside the compensation frame 400, thus keeping the rice inside the compensation frame 400 dry. During the tempering stage, when the moisture content of the rice detected by the moisture meter 403 is small compared to the standard, the corresponding drive component 432 moves the connecting plate 431, opening a corresponding number of ventilation holes 411 to facilitate the entry of hot air and increase the drying time. Specifically, the moisture meter 403 feeds back the detection result to the control system via an electrical signal. The control system then controls the corresponding number of drive components 432 to operate via the electrical signal. The corresponding number of drive components 432 move the corresponding number of connecting plates 431 out of the sealing frame 433, thereby opening the corresponding ventilation holes 411 (e.g., ...). Figure 10As shown, the number of driving components 432 operating in the two air collection frames 401 on both sides of the same compensation frame 400 is the same, and the number of driving components 432 operating is adjusted accordingly based on the detection results; the hot air in the air inlet frame 460 enters the corresponding air collection frame 401 through the connecting pipe 461, and the hot air in the air collection frame 401 enters the compensation frame 400 through the corresponding air vent 411, thereby converting a part of the compensation frame 400 into a drying area. The hot air continues to dry the rice between multiple guide plates 410, thereby increasing the drying time of the rice and ensuring the drying quality of the rice; when the rice passes the moisture detector 403 below the compensation frame 400, the moisture detector 403 re-detects the moisture of the rice. If the detection result meets the requirements, the rice directly enters the tempering frame 450 below.

[0062] See Figure 1 , Figure 5 , Figure 7 and Figure 9 Multiple guide plates 451 are installed inside the suspension frame 450, which are evenly distributed from top to bottom and staggered from left to right.

[0063] In practice, the rice grains falling from the compensation frame 400 fall downwards through multiple guide plates 451 and undergo a tempering process. After passing through the tempering frame 450, the rice grains enter the compensation frame 400 below. The tempering time is changed by controlling the closure of the ventilation holes 411. Specifically, the moisture detector 403 above the compensation frame 400 detects the moisture content inside and outside the rice grains after tempering. If the difference between the surface moisture and the internal moisture of the rice grains drops to within 0.5%, tempering is considered complete. If the difference between the moisture content inside and outside the rice grains reaches the standard, the moisture detector 403 transmits the detection result via an electrical signal. Feedback is sent to the control system, which uses electrical signals to control all the driving components 432 within the corresponding compensation frame 400 to operate. All the driving components 432 move all the connecting plates 431 out of the sealing frame 433, thus converting the entire area within the compensation frame 400 into a drying area. This effectively reduces the waiting time for the rice to soften and improves the overall drying efficiency. If the difference in moisture content between the inside and outside of the rice exceeds the standard, the control system uses electrical signals to control the corresponding number of driving components 432 above the compensation frame 400 to move the corresponding connecting plates 431 tightly against the sealing frame 433 (e.g., ...). Figure 12As shown in the diagram, the upper area within the compensation frame 400 is converted into a tempering area. When the rice passes through the moisture detector 403 below the compensation frame 400, the moisture detector 403 detects the internal and external moisture content of the rice. If the detection result meets the standard, the rice remains unchanged. If the detection result does not meet the standard, the control system continues to control the corresponding number of driving components 432 through electrical signals to drive the corresponding connecting plate 431 to fit tightly against the sealing frame 433, thereby increasing the tempering area within the compensation frame 400 until the detection result of the moisture detector 403 below meets the standard, thus ensuring the quality of rice tempering, thereby improving the rice drying effect and preventing damage to the rice.

[0064] See Figure 1 , Figure 6 , Figure 7 and Figure 9 The guide plate 410 is composed of two rotating plates that are hinged to each other. The two rotating plates are arranged in a cone shape with the hinge facing upward. The multiple guide plates 410 of the intake guide group 41 and the multiple guide plates 410 of the exhaust guide group 42 are staggered.

[0065] See Figure 1 , Figure 6 , Figure 7 and Figure 9 The movable rod 430 is provided with multiple adjusting components. The adjusting components include a cylindrical sleeve 434 sleeved and installed on the movable rod 430. Two lifting protrusions 435 are symmetrically arranged on the outer periphery of the cylindrical sleeve 434. The two lifting protrusions 435 are respectively installed on the inner sidewalls of the two rotating plates of the guide plate 410.

[0066] In practice, during the rice drying stage, when the moisture content of the rice detected by the moisture meter 403 deviates significantly from the standard, and after the entire area within the compensation frame 400 at the lower end of the drying frame 440 has been converted into the drying area, if the result detected by the moisture meter 403 below the compensation frame 403 still does not meet the standard, the drive component 432 further moves the connecting plate 431. This, along with the movement rod 430 and the adjusting component, changes the spacing of the guide plates 410, adjusting the rice flow speed to further increase the drying time (e.g., ...). Figure 11 As shown), specifically: the control system continues to control the corresponding number of driving components 432 to move the corresponding connecting plate 431 through electrical signals. The connecting plate 431 drives multiple moving rods 430 to move. The moving moving rods 430 drive multiple cylindrical sleeves 434 to push the corresponding lifting protrusions 435. The lifting protrusions 435 on both sides drive the two rotating plates of the guide plate 410 to rotate in opposite directions, thereby changing the distance between two adjacent guide plates 410 (e.g., Figure 14As shown in the figure, this reduces the rate at which the rice flows downward, thereby further increasing the drying time of the rice and ensuring the drying effect. At this time, it is necessary to pay attention to reducing the amount of rice entering through the feed hole 11 to avoid rice overflow. Within the reasonable range of rice falling, the smaller the distance between the two guide plates 410, the lower the rice flow rate and the longer the rice drying time, so as to achieve the drying standard.

[0067] Similarly, during the rice tempering stage, when the compensation frame 400 at the lower end of the tempering frame 450 has been completely converted into the tempering area, and the moisture detector 403 located below the compensation frame 400 still fails to meet the standard for detecting the moisture content inside and outside the rice, the control system continues to control the corresponding driving component 432 at the bottom of the corresponding compensation frame 400 to work via an electrical signal. That is, the driving component 432 at the bottom of the air collection frame 401 connected to the exhaust pipe 470 works. The driving component 432 drives the corresponding connecting plate 431 to move, the connecting plate 431 drives multiple moving rods 430 to move, and the moving moving rods 430 drive multiple cylindrical sleeves 434 to push the corresponding lifting protrusions 435. The lifting protrusions 435 on both sides drive the two rotating plates of the guide plate 410 to rotate in opposite directions (e.g., Figure 13 As shown in the figure, this changes the spacing between two adjacent guide plates 410, thereby reducing the rate at which the rice flows downward, thus further increasing the time for the rice to soften and ensuring the effect of softening.

[0068] After the upper drying unit 4 dries and tempers the rice for a period of time, the rice enters the lower drying unit 4 to continue drying and tempering. The number of drying units 4 can be flexibly increased according to actual needs until the dried rice reaches the standard. After reaching the drying standard, the rice enters the discharge frame 20 for cooling, and then is discharged through the discharge hole 21 until all the rice is dried, and then the drying process ends.
