Description

Technical Field

[0001] This invention belongs to the field of agricultural product cleaning and drying machinery technology, specifically relating to an integrated soybean cleaning and drying machine for soybean flour production. Background Technology

[0002] Soybean flour, as an important plant protein and food ingredient, directly impacts the quality and safety of downstream products through its processing. During processing, raw soybeans often contain solid impurities such as mud and gravel, as well as contaminants like insect eggs, mold, and microorganisms. Therefore, cleaning is an essential pre-treatment step. Currently, the industry commonly uses a combination of mechanical cleaning and water rinsing to improve the cleanliness of the soybeans.

[0003] However, existing cleaning methods that combine mechanical cleaning with hydraulic rinsing struggle to effectively distinguish and treat impurities and contaminants of different properties, especially those with strong adhesion. Furthermore, while traditional hydraulic rinsing equipment includes a subsequent drying mechanism, prolonged soaking still significantly increases the surface and internal moisture of soybeans. Drying equipment reduces internal moisture in a short time, but if subsequent dehydration is insufficient, high-moisture soybeans can easily adhere to the grinding equipment, increase energy consumption, and potentially promote microbial growth, affecting product yield and storage stability.

[0004] To address the aforementioned problems, this invention proposes a comprehensive soybean washing and drying machine for soybean flour production. This machine can classify and segmentally clean mixed and attached impurities, and utilizes a steam cleaning and instant drying mechanism to thoroughly remove contaminants while preventing abnormal increases in soybean moisture content. This provides suitable material conditions for subsequent grinding processes, thereby ensuring the continuity of the production process and the quality of the final product. Summary of the Invention

[0005] To address the aforementioned shortcomings in the existing technology, this invention provides an integrated soybean washing and drying machine for soybean flour production, which solves the problem that the existing technology cannot classify and segmentally clean mixed impurities and attached impurities, and that using water rinsing will significantly increase the internal humidity of soybeans.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: A soybean washing and drying integrated machine for soybean flour production includes: a frame, a brushing mechanism, a rinsing mechanism, a drive mechanism, and a drying mechanism; The frame is equipped with a dust collection chamber, a water tank, and a connecting pipe. The brushing mechanism is installed above the dust collection chamber, and the rinsing mechanism is installed above the water tank.

The two ends of the first outer cylinder are provided with first material inlets. The side wall of the first outer cylinder is provided with a first brush groove and a first filter hole. The floating brush is slidably disposed on the first brush groove, and the first roller is rotatably disposed in the first outer cylinder. The rinsing mechanism includes a second outer cylinder, a second roller, a steam brush, and a second nozzle. The second outer cylinder is fixedly mounted on the frame. The two ends of the second outer cylinder are provided with second feed inlets. The side wall of the second outer cylinder is provided with a second brush groove and a second filter hole. The second roller is rotatably mounted in the second outer cylinder. The steam brush is slidably mounted in the second brush groove. The second nozzle is fixedly mounted on the frame. The first material inlet on the side of the first outer cylinder near the drive mechanism and the second material inlet on the side of the second outer cylinder near the drive mechanism are connected by a connecting pipe; The drive mechanism is fixedly mounted on the frame, and the drive mechanism is connected to the first roller and the second roller; The drying mechanism is mounted on the frame.

[0007] Furthermore, a first air supply groove is provided on the end face of the first outer cylinder away from the drive mechanism.

[0008] Furthermore, a second air supply groove is provided on the end face of the first roller away from the drive mechanism, and the first air supply groove and the second air supply groove are rotatably engaged.

[0009] Furthermore, the first roller is provided with an air supply chamber and an inclined jet hole, the second air supply groove is connected to the air supply chamber, and the inclined jet hole is provided on the side wall of the first roller.

[0010] Furthermore, the floating brush is provided with a first spring and a first bristle. The floating brush is connected to the first outer cylinder through the first spring, and the first bristle is fixedly disposed on the end face of the floating brush near the first roller.

[0011] Furthermore, the steam brush is provided with a second spring, a steam chamber, a first nozzle, and a second bristle. The steam brush is connected to the second outer cylinder through the second spring. The steam chamber is disposed on the steam brush. The first nozzle and the second bristle are disposed on the end face of the steam brush near the second roller. The first nozzle is connected to the steam chamber.

[0012] Furthermore, the drive mechanism is also equipped with a universal joint, and the drive mechanism is connected to the second roller through the universal joint.

[0013] Furthermore, the end of the rinsing mechanism furthest from the drive mechanism is tilted downwards.

[0014] Furthermore, the drying mechanism includes a conveyor and a fan. The conveyor is fixedly installed in the water tank. The end of the conveyor near the rinsing mechanism is located below the second material inlet on the side of the second outer cylinder away from the drive mechanism. The fan is installed on the side wall of the frame.

[0015] Furthermore, a drain pipe is also provided on the frame, and the drain pipe is connected to the dust collection chamber.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention discloses a soybean washing and drying integrated machine for soybean flour production. By setting up two independent and sequentially connected mechanisms for brushing and rinsing, it realizes the classification and fine processing of soybean impurities. The brushing mechanism uses mechanical bristles and high-pressure gas to effectively remove solid particulate impurities such as mud and gravel mixed in the soybeans. Then, the rinsing mechanism uses steam to efficiently kill and remove contaminants such as insect eggs, mold spots and microorganisms attached to the surface of the soybeans. The cleaning method of dry brushing followed by steam washing overcomes the shortcomings of traditional single cleaning methods that are difficult to take into account different types of impurities, and significantly improves the overall cleanliness.

[0017] 2. The present invention discloses an integrated soybean washing and drying machine for soybean flour production. By replacing traditional water washing with steam washing and combining it with immediate drying, the amount of water generated by condensation during washing is far less than that generated by water washing, and the washing time is also much shorter than that of water washing. This avoids the problem of soybeans absorbing too much water and causing a significant increase in internal humidity from the source. Subsequently, the integrated drying mechanism quickly dries the washed soybeans, causing the surface moisture to evaporate rapidly. This ensures that the soybeans maintain a suitable and uniform low moisture content when entering the grinding section. This effectively prevents the equipment efficiency from decreasing and the energy consumption from increasing due to wet and sticky materials during the subsequent grinding process.

[0020] To enable those skilled in the art to better understand the present invention, the technical solution of the present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0021] In the description of this application, it should be noted that the directional terms such as "center", "lateral", "longitudinal", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", and "counterclockwise" indicate the orientation and positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. They should not be construed as limiting the specific protection scope of this application.

[0022] It should be noted that the terms "first," "second," etc., in the specification and claims of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0023] Please see Figures 1 to 12As shown, a soybean washing and drying integrated machine for soybean flour production includes: a frame 1 for support and sewage discharge; a brushing mechanism 2 for removing solid impurities such as mud and gravel mixed in soybeans; a rinsing mechanism 3 for using steam to remove contaminants such as insect eggs, mold and microorganisms attached to the surface of soybeans; a drive mechanism 4 for driving the brushing mechanism 2 and the rinsing mechanism 3; and a drying mechanism 5 for drying the washed soybeans.

[0024] The frame 1 is equipped with a dust settling chamber 11, a water tank 12, and a connecting pipe 13. The brushing mechanism 2 is installed above the dust settling chamber 11, and the rinsing mechanism 3 is installed above the water tank 12. The frame 1 is also equipped with a drain pipe 111, which is connected to the dust settling chamber 11. It can be understood that when the rinsing mechanism 3 cleans the soybean surface of contaminants such as insect eggs, mold, and microorganisms, the condensate generated by steam condensation flows into the water tank 12 of the frame 1. The brushing mechanism 2 separates the soybeans from solid impurities such as mud and gravel. The mud, gravel, and other solid impurities fall into the dust settling chamber 11, and the condensate in the water tank 12 flows into the dust settling chamber 11 to form mixed wastewater. The mixed wastewater is discharged from the equipment through the drain pipe 111.

[0025] The washing mechanism 2 includes a first outer cylinder 21, a floating brush 22, and a first roller 23. The first outer cylinder 21 is fixedly mounted on the frame 1. First feed inlets 211 are provided at both ends of the first outer cylinder 21. First brush grooves 212 and first filter holes 213 are provided on the side wall of the first outer cylinder 21. The floating brush 22 is slidably disposed on the first brush groove 212, and the first roller 23 is rotatably disposed within the first outer cylinder 21.

[0026] Specifically, the floating brush 22 is equipped with a first spring 221 and first bristles 222. The floating brush 22 is connected to the first outer cylinder 21 via the first spring 221, and the first bristles 222 are fixedly disposed on the end face of the floating brush 22 near the first roller 23. It should be noted that an axial material groove is provided on the side wall of the first roller 23.

[0027] This can be understood as follows: when the first roller 23 rotates to the point where the material trough and the floating brush 22 are misaligned, the side wall of the first roller 23 cooperates with the floating brush 22 to push the floating brush 22 outward. The floating brush 22 slides along the first brush groove 212 to the side away from the first roller 23. During this process, the first spring 221 is shortened by force. When the first roller 23 rotates to the point where the material trough and the floating brush 22 are aligned, the first spring 221 releases its elastic force and extends to push the floating brush 22 to slide along the first brush groove 212 toward the first roller 23.

[0028] It can be understood that the drive mechanism 4 drives the first roller 23 to rotate in the first outer cylinder 21. The first roller 23 drives the soybeans located in the gap between the first roller 23 and the first outer cylinder 21 to rotate together. The soybeans come into contact with the first bristles 222 of the floating brush 22. The first bristles 222 separate the solid impurities such as mud and gravel mixed and attached to the soybeans from the soybeans.

[0029] Specifically, a first air supply groove 214 is provided on the end face of the first outer cylinder 21 away from the drive mechanism 4. Specifically, a second air supply groove 232 is provided on the end face of the first roller 23 away from the drive mechanism 4, and the first air supply groove 214 and the second air supply groove 232 are rotatably engaged. Correspondingly, the first roller 23 is provided with an air supply chamber 231 and an inclined jet hole 234, the second air supply groove 232 is connected to the air supply chamber 231, and the inclined jet hole 234 is located on the side wall of the first roller 23. It should be noted that the inclined jet hole 234 is inclined towards the drive mechanism 4.

[0030] This can be understood as follows: the first air supply trough 214 is connected to the air supply pipe in the factory. The first air supply trough 214 and the second air supply trough 232 are rotatably coupled. While not affecting the rotation of the first roller 23, the first air supply trough 214 supplies air to the second air supply trough 232. The high-pressure gas entering the second air supply trough 232 enters the air supply chamber 231 of the first roller 23. Then, it is sprayed through the inclined jet hole 234 between the material trough of the first roller 23 and the first outer cylinder 21. The high-pressure gas blows the separated solid impurities such as mud and gravel into the dust settling chamber 11 through the first filter hole 213, while pushing the soybeans towards the connecting pipe 13.

[0031] The first feed port 211 on the side of the first outer cylinder 21 near the drive mechanism 4 is connected to the second feed port 311 on the side of the second outer cylinder 31 near the drive mechanism 4 via a connecting pipe 13. That is, the soybeans that have been washed in the washing mechanism 2 enter the rinsing mechanism 3 through the connecting pipe 13.

[0032] The rinsing mechanism 3 includes a second outer cylinder 31, a second roller 32, a steam brush 33, and a second nozzle 34. The second outer cylinder 31 is fixedly mounted on the frame 1. Second feed inlets 311 are provided at both ends of the second outer cylinder 31. Second brush grooves 312 and second filter holes 313 are provided on the side wall of the second outer cylinder 31. The second roller 32 is rotatably mounted within the second outer cylinder 31. The steam brush 33 is slidably mounted within the second brush groove 312. The second nozzle 34 is fixedly mounted on the frame 1.

[0033] The second nozzle 34 is connected to the steam pipe in the plant.

[0034] It should be noted that an axial material groove is provided on the side wall of the second roller 32.

[0035] Specifically, the steam brush 33 is equipped with a second spring 331, a steam chamber 332, a first nozzle 333, and second bristles 334. The steam brush 33 is connected to the second outer cylinder 31 via the second spring 331. It can be understood that when the drive mechanism 4 drives the second roller 32 to rotate via the universal joint 41, the second roller 32 will cause the soybeans in the gap between the second roller 32 and the second outer cylinder 31 to rotate together.

[0036] The steam chamber 332 is mounted on the steam brush 33. The first nozzle 333 and the second bristles 334 are mounted on the end face of the steam brush 33 near the second roller 32. The first nozzle 333 is connected to the steam chamber 332. It should be noted that the steam chamber 332 is connected to the steam pipe in the factory and provides high-pressure steam to the steam chamber 332. It can be understood that the high-pressure steam in the steam chamber 332 is sprayed onto the soybeans through the first nozzle 333, while the second bristles 334 brush the surface of the soybeans. Under the action of the high-pressure steam and the second bristles 334, contaminants such as insect eggs, mold spots, and microorganisms attached to the surface of the soybeans are quickly brushed off. Some of the contaminants brushed off are carried away with the condensate formed by the condensation of the high-pressure steam and flow through the second filter hole 313 into the water tank 12.

[0037] The end of the rinsing mechanism 3 furthest from the driving mechanism 4 is inclined downwards. It should be noted that the downward inclination of the end of the rinsing mechanism 3 furthest from the driving mechanism 4 not only allows the soybeans to move towards the end furthest from the driving mechanism 4 in the rinsing mechanism 3 under the action of gravity, but also prevents the condensate formed in the rinsing mechanism 3 from flowing into the scrubbing mechanism 2, thereby affecting the separation of impurities in the scrubbing mechanism 2.

[0038] The drive mechanism 4 is fixedly mounted on the frame 1, and is connected to the first roller 23 and the second roller 32. A universal joint 41 is also provided on the drive mechanism 4, and the drive mechanism 4 is connected to the second roller 32 via the universal joint 41.

[0039] The drying mechanism 5 is installed on the frame 1. The drying mechanism 5 includes a conveyor 51 and a fan 52. The conveyor 51 is fixedly installed in the water tank 12. The end of the conveyor 51 near the rinsing mechanism 3 is located below the second feed port 311 on the side of the second outer cylinder 31 away from the drive mechanism 4. The fan 52 is installed on the side wall of the frame 1.

[0040] This can be understood as follows: the soybeans that have been cleaned in the rinsing mechanism 3 fall onto the conveyor 51 through the second feed port 311 on the side of the second outer cylinder 31 away from the drive mechanism 4. At the same time, the second nozzle 34 sprays high-pressure steam onto the soybeans on the conveyor 51 to further separate the contaminants on the soybeans and further heat the soybeans. The fan 52 blows air onto the soybeans on the conveyor 51, causing the moisture on the surface of the soybeans to evaporate quickly.

[0041] The working principle of this invention is as follows: Soybeans are fed into the washing mechanism 2 through the first feed port 211 on the side of the first outer cylinder 21 away from the drive mechanism 4, either manually or by conveying equipment.

[0042] The drive mechanism 4 drives the first roller 23 to rotate within the first outer cylinder 21. The first roller 23 rotates the soybeans located in the gap between the first roller 23 and the first outer cylinder 21. The soybeans come into contact with the first bristles 222 of the floating brush 22, which separates the solid impurities such as mud and gravel mixed with and attached to the soybeans. An inclined jet nozzle 234 sprays gas between the feed trough of the first roller 23 and the first outer cylinder 21. The high-pressure gas blows the separated solid impurities such as mud and gravel into the dust settling chamber 11 through the first filter hole 213, while simultaneously pushing the soybeans toward the connecting pipe 13.

[0043] The soybeans that have been washed in the washing mechanism 2 enter the rinsing mechanism 3 through the connecting pipe 13.

[0044] When the drive mechanism 4 drives the second roller 32 to rotate via the universal joint 41, the second roller 32 will cause the soybeans in the gap between the second roller 32 and the second outer cylinder 31 to rotate continuously. At the same time, the soybeans move away from the drive mechanism 4 in the rinsing mechanism 3 under the action of gravity. The high-pressure steam in the steam chamber 332 is sprayed onto the soybeans through the first nozzle 333, while the second bristles 334 brush the surface of the soybeans. Under the action of the high-pressure steam and the second bristles 334, the contaminants such as insect eggs, mold spots and microorganisms attached to the surface of the soybeans are quickly brushed off. Some of the contaminants brushed off are carried away with the condensate formed by the condensation of the high-pressure steam and flow through the second filter hole 313 into the water tank 12.

[0045] Soybeans that have been cleaned in the rinsing mechanism 3 fall onto the conveyor 51 through the second feed port 311 on the side of the second outer cylinder 31 away from the drive mechanism 4. At the same time, the second nozzle 34 sprays high-pressure steam onto the soybeans on the conveyor 51 to further separate the contaminants on the soybeans and further heat the soybeans. The fan 52 blows air onto the soybeans on the conveyor 51, causing the moisture on the surface of the soybeans to evaporate quickly.

[0046] The condensate mixed with pollutants in the water tank 12 flows into the dust settling tank 11, where it mixes with the impurities that settle at the bottom of the dust settling tank 11 to form mixed wastewater. The mixed wastewater is discharged from the equipment through the drain pipe 111.
