Abstract
Description
Technical Field
[0001] This invention relates to the field of flour processing equipment technology, and more specifically, to a flour processing device and processing method. Background Technology
[0002] The process of processing wheat into flour generally involves the following steps: screening, dehulling, milling, and packaging. Because wheat contains many impurities, screening is often interspersed throughout these steps. The entire processing involves multiple screenings of the wheat, semi-finished flour, and finished flour to ensure quality. In current flour processing technology, traditional stone mills are gradually being replaced by modern flour mills. Modern flour processing equipment typically grinds the flour, then stops the machine after grinding, and removes the flour for screening. Unqualified flour is then re-grinded and screened again. This increases the number of machines and the floor space required. The constant switching between grinding and screening increases downtime, reducing production efficiency and significantly increasing processing costs. Summary of the Invention

A heater is provided at the top end of the side of the partition in the sandwich cavity, and a plurality of through holes are provided at the bottom of the sandwich cavity, which connect the sandwich cavity to the inside of the collection box.
[0010] Preferably, the rolling mechanism includes a motor, which is fixed at the upper center of the outer side of the processing box.

[0012] Preferably, the bottom groove is provided with an opening, the screen is disposed in the opening, and the bottom of the screen is provided with a plurality of compression springs, the bottoms of the compression springs being fixed to the grid screen respectively.
[0013] According to another aspect of the present invention, a flour processing method is provided.
[0014] The method for processing this flour includes the following steps:
[0015] First, the ground flour is fed into the feeding channel and then enters the inclined conveyor table.
[0016] It slides down the inclined surface of the inclined conveyor table, and during the sliding process, it drives the conveying mechanism to run;
[0017] After the material conveying mechanism is activated, the crushing roller and several hammer blocks will all start to move;
[0018] After the grinding rollers rotate, the falling flour will be ground along with the rotation of the grinding rollers;
[0019] During the rolling motion of the roller, the flour is also struck up and down by the hammer blocks. The striking motion breaks up the falling lumps of flour, and the vibration generated by the striking motion provides the sliding power for the flour conveyor.
[0020] The flour falls onto the sieve on the bottom trough;
[0021] Drive the rolling mechanism, and through the operation of the rolling mechanism, drive several roller shafts on the screen to rotate;
[0022] When the roller is rolling, it will crush the falling flour again, making the flour finer and more uniform.
[0023] Under the pressure generated during rolling, the screen will be subjected to a certain downward force, causing the screen to sway slightly up and down. The swaying force will press the compression spring below, and the compression force of the spring will provide the screen with a certain swaying. At this time, the flour on the screen will improve the filtration efficiency during the pressing process.
[0024] At the same time, after the rolling mechanism is driven, multiple pulleys in the interlayer cavity rotate. The rotation of the pulleys will generate a certain wind force. After the wind force is generated, the heat generated inside will enter the collection box through the through hole three.
[0025] The heat inside the collection box allows the processed flour to absorb heat, facilitating better collection and processing of the flour.
[0026] Compared with the prior art, the advantages and positive effects of the present invention are as follows:
[0027] 1. A collection box is installed at the bottom of the processing box to facilitate the collection of processed flour for subsequent storage and processing. A conveying mechanism is installed below the feeding channel to allow the ground flour to undergo secondary processing, preventing the direct storage of flour with clumps and unground particles, thus improving the flour processing effect. Then, in conjunction with the rolling mechanism, the flour is rolled again. After multiple rolling processes, the flour becomes finer, reducing the amount of substandard flour remaining in the processing box, improving the grinding quality, and automatically screening the flour.
[0028] 2. This equipment greatly improves the grinding quality by directly screening and collecting the flour during the grinding process, reducing the amount of substandard flour remaining in the processing box, increasing production efficiency, and reducing processing costs.
[0029] 3. A heater is installed in the interlayer cavity. The heat generated by the heater is transferred to the interlayer cavity and then flows into the collection box through several through holes below. When the multiple pulleys in the interlayer cavity rotate, their own rotation also generates wind force, which increases the speed of heat transfer and enables the heat source to be quickly input into the collection box below, providing a certain temperature inside the collection box. This allows the flour after screening to be exposed to the temperature, which can reduce the moisture absorption of the flour. Attached Figure Description

A grid 7 is provided on the top of the collection box 1, located on one side of the screen 6. A rolling mechanism 8 is provided on the screen 6. A conveying mechanism 9 is provided at the bottom of the processing box 3, corresponding to below the feeding channel 4. The conveying mechanism 9 includes an inclined conveyor table 10. A rolling roller 11 is inserted into the inclined conveyor table 10 near its center. A pulley 2 12 is connected to one side of the rolling roller 11. A belt 13 is provided on the pulley 2 12. The other side of the belt 13 is wound around the pulley 14. A gear 15 is provided on the side of the pulley 14 away from the inner wall of the processing box 3. A meshing gear 16 is provided above the gear 15. A shaft 17 is inserted through the middle of the gear 16. The shaft 17 passes through the processing box 3 and is connected to a motor 18 provided outside the processing box 3. A rotating disk 19 is provided at the other end of the shaft 17. A drive arm 20 is provided on the side of the rotating disk 19 away from the gear 16. A slider 21 is provided at the other end of the drive arm 20. An L-shaped support 22 is provided on the upper inner side of the slider 21. Several hammer rods 23 are provided on the L-shaped support 22. A hammer block 24 is provided at the bottom of each hammer rod 23. A matching track 25 is provided on the side of the slider 21 away from the L-shaped support 22. A U-shaped upright plate 26 is provided on the side of the track 25 away from the slider 21.
[0046] The inclined conveyor platform 10 has through holes 27 on both sides near the center at its lower part. A roller shaft 28 is horizontally inserted through the through hole 27. A crushing roller 11 is sleeved on the roller shaft 28. A pulley 12 is sleeved on one end of the roller shaft 28. The surface of the crushing roller 11 is in contact with the bottom wall of the inclined conveyor platform 10. The surface of the crushing roller 11 has several strip-shaped grooves. A support column 29 is provided on the bottom side of the inclined conveyor platform 10 away from the screen 6. A support platform 30 is provided at the bottom of the support column 29. The bottom of the support platform 30 is fixed to one side of the bottom of the processing box 3. The upright plate 26 is located at the lower left side of the inclined conveyor platform 10. A frame plate 31 is mounted on the upper part of the upright plate 26. The hammer rod 23 passes through the frame plate 31. Side grooves are provided at the center of both sides of the frame plate 31. The drive arm 20 and the rotating disk 19 are both located in the side groove on one side. A door panel is provided on the discharge window 2.
[0047] The upright plate 26 is designed in a U-shape, which allows it to rest on the bottom of the inclined conveyor table 10. The inclined conveyor table 10 forms a folded, inclined platform. When flour falls onto the higher inclined surface on the right side of the inclined conveyor table 10, it rolls downwards with the tilt angle. During this rolling motion, the crushing roller 11 crushes the falling flour. Since the crushing roller 11 is in contact with the bottom wall of the inclined conveyor table 10, when the flour is conveyed downwards, if the crushing roller 11 is stationary, the flour will be blocked and stop above the crushing roller 11. When the crushing roller 11 rotates, it will carry the flour downwards along with the rotating trajectory, crushing it as it rolls. The crushing roller 11 also provides a certain buffer during flour conveying, reducing the flour's conveying speed and preventing it from piling up.
[0048] Additionally, a partition 32 is provided on the side of the bottom trough 5 away from the conveying mechanism 9. A sandwich cavity 33 is formed between the partition 32 and the inner wall of the processing box 3. A heater 42 is provided at the top end of the side of the partition 32 within the sandwich cavity 33. Several through holes 34 are provided at the bottom of the sandwich cavity 33, which connect the sandwich cavity 33 to the interior of the collection box 1. The rolling mechanism 8 includes a motor 35, which is fixed at the upper center of the outer side of the processing box 3. The output end of the motor 35 is connected to a pulley shaft, which passes through the processing box 3. A pulley 36 is provided at the end of the pulley shaft away from the motor 35, and the pulley 36 is movably connected to the center of the upper side of the partition 32. Belt pulleys 37 are provided on both sides below the pulley 36 on the side of the partition 32. Several pulleys 38 are provided below the pulleys 37 on the lower part of the side of the partition 32. The pulleys 38 are connected to the pulleys 37 and 36 by belts 39. A central shaft is inserted through the middle of each pulley 38 and passes through the partition 32. A roller shaft 40 is provided at the end of the central shaft away from the pulleys 38. The other end of the roller shaft 40 is horizontally connected to the side of the bottom groove 5. The bottom groove 5 has an opening. The screen 6 is placed in the opening. Several compression springs 41 are provided at the bottom of the screen 6. The bottom of the compression springs 41 are respectively fixed to the grid screen 7.
[0049] There is a certain gap between the sieve 6 and the grid 7. When the sieve 6 is subjected to pressure from above, the sieve 6 will press the compression spring 41 at the bottom, causing the gap between the sieve 6 and the grid 7 to change. After screening, the sieve 6 will screen the flour. After the gap between the sieve 6 and the grid 7 changes, the speed of flour screening and conveying will increase. When the flour is compressed in space, it will also splash up and hit its side wall, improving the quality of the flour.
[0050] Example 2
[0051] A flour processing method includes the following steps:
[0052] S101: First, the ground flour is fed into the feeding channel 4 and then enters the inclined conveyor table 10 through the feeding channel 4;
[0053] S103: The material slides down the inclined surface of the inclined conveyor table 10, and during the sliding process, the material conveying mechanism 9 is driven to run.
[0054] S105: After the material conveying mechanism 9 is running, the crushing roller 11 and several hammer blocks 24 will all start to move;
[0055] S107: After the grinding roller 11 rotates, the falling flour will be ground along with the rotation of the grinding roller 11;
[0056] S109: During the rolling motion of the rolling roller 11, it will also be struck by the hammer block 24 as it moves up and down. When it is struck, it can crush the falling lumps of flour. At the same time, the vibration generated by the striking motion provides the sliding power for the flour conveyor.
[0057] S1011: The flour falls onto the sieve in the bottom groove 5;
[0058] S1013: Drive the rolling mechanism 8, which in turn drives several roller shafts 40 on the screen 6 to rotate.
[0059] S1015: When the roller 40 is rolling, it will crush the falling flour again, making the flour more delicate and uniform.
[0060] S1017: Under the pressure generated during rolling, the screen 6 will be subjected to a certain downward force, causing the screen 6 to produce a slight up-and-down swaying force. The swaying force will press the compression spring 41 below. Under the compression force of the compression spring 41, the screen 6 will be provided with a certain swaying. At this time, the flour on the screen 6 will improve the filtration efficiency during the pressing process.
[0061] S1019: At the same time, after the rolling mechanism 8 is driven, multiple pulleys in the interlayer cavity 33 rotate. After the pulleys rotate, a certain wind force will be generated. After the wind force is generated, the heat generated inside will enter the collection box 1 through the through hole 34.
[0062] S1021: The inside of the collection box 1 receives a certain amount of heat, which causes the processed flour to receive heat, making it easier to collect and process the flour.
[0063] Detailed usage and function of this embodiment:
[0064] After initial grinding, the flour is conveyed into the feed channel 4 and falls onto the inclined conveyor table 10. As the inclined conveyor table 10 slides down its slope, when it reaches the grinding roller 11, the drive motor 18 starts running. The motor 18 drives the shaft 17 to rotate, which in turn drives the gear 16 to rotate. The gear 16 then drives the meshing gear 15 below to rotate. After the gear 15 rotates, the side pulley 14 pulls the pulley 12 to rotate via the belt 13. The roller 2... 8 will rotate together, which will drive the upper-mounted crushing roller 11 to rotate. After the crushing roller 11 rotates, it will bring up the flour falling from the side and roll down together. As the crushing roller 11 rotates, it will crush the flour. The crushed flour will slide down and be continuously hammered up and down by several hammer blocks 24 below. When gear 16 rotates, it will drive the rotating disk 19 connected to the side to rotate. The drive arm 20 connected to the side end of the rotating disk 19 will push the slider 21 on the track. The vertical movement of motor 25 causes hammer rod 23 to strike the flour vertically. The hammer block 24 then strikes the flour, impacting it and causing vibrations that knock the flour off the inclined conveyor table 10. The flour falls onto the screen 6 in the bottom trough 5, driving motor 35. Motor 35 then rotates pulley 36, which in turn drives another pulley via belt 39. When pulley 38 rotates... This will drive the roller shaft 40 to rotate, and the roller shaft 40 will roll on the screen 6, rolling and pressing the flour on the screen 6. The flour on the screen 6 will be pressed down by the rolling force. As the screen 6 falls down, the screen 6 is also subjected to the elastic action of the compression spring 41, changing the distance between the screen 6 and the grid 7 below. Finally, the flour enters the collection box 1. At this time, after the heater 42 is working, the heat generated will be transferred to the interlayer cavity 33, and finally transferred to the collection box 1 through the through hole 34.
[0065] Through the specific embodiments described above, those skilled in the art can easily implement the present invention. However, it should be understood that the present invention is not limited to the specific embodiments described above. Based on the disclosed embodiments, those skilled in the art can arbitrarily combine different technical features to achieve different technical solutions.

After the wind force is generated, the heat generated inside will enter the collection box (1) through the through hole three (34). The heat received inside the collection box (1) causes the processed flour to receive heat, which facilitates better collection and processing of the flour.
