Description

Technical Field

[0001] The present invention relates to the field of wheat flour processing, and in particular to automated processing equipment and a processing method for purple glutinous whole wheat flour. Background Art

[0002] In modern society, as people become more health-conscious, whole grains and foods rich in dietary fiber are increasingly favored by consumers. Purple glutinous rice whole-wheat flour, due to its rich nutritional value and unique flavor, is gaining increasing market attention. However, existing milling equipment often suffers from low processing efficiency, high energy consumption, and high equipment costs when processing purple glutinous rice whole-wheat flour, failing to fully meet market demands for efficient, economical, and environmentally friendly processing.

[0003] With the advancement of science and technology, technical personnel in related fields have also optimized the technical means for processing and preparing purple glutinous rice whole wheat flour. In order to make a more accurate comparison, the whole wheat flour processing device and whole wheat flour processing technology disclosed in the Chinese patent publication number CN104923330A include a grinding mill, a powder screening device, a powder storage tank and a processing grader, etc. When in use, the wheat flour is crushed by the processing grader, and the cell wall destruction technology is used to crush the bran and ensure the integrity of the protein in the wheat flour, without reducing the gluten quality of the wheat flour; only 1 to 2 grinding mills and 1 to 2 processing graders are needed to process whole wheat flour that meets the requirements, reducing the number of grinding mills, reducing the volume of equipment, reducing the investment cost of equipment, and having a good processing effect.

[0004] However, when the above-mentioned prior art is used to process purple glutinous wheat, the following problems still exist: The above-mentioned device crushes and grinds the wheat grains through the cooperation between the processing classifier and the grinding mill. When the above-mentioned device is used to prepare purple glutinous rice whole wheat flour, at least one classifier and one grinding mill need to be laid flat on the ground to complete the grinding and sorting of the whole wheat flour during the processing. That is, during use, the classifier and the grinding mill need to be maintained separately after use, which does not effectively reduce the equipment investment cost, and the use of at least two devices at the same time also requires a large land area.

[0005] Therefore, based on the above-stated viewpoint, there is still room for optimization in the existing technical means of processing purple glutinous wheat. Summary of the Invention

[0006] In order to solve the above problems, the present invention provides an automated processing device for purple glutinous whole wheat flour, comprising a processing cylinder, the processing cylinder being connected to a feed channel, and the processing cylinder being provided with a processing component for grinding wheat grains, the processing component comprising: The temporary storage cylinder is located inside the processing cylinder. The temporary storage cylinder is hollow inside to form a temporary storage cavity connected to the feed channel. The two ends of the temporary storage cylinder separate the interior of the processing cylinder into a sorting cavity and a grinding cavity.

[0007] The processing end includes at least one grinding roller and a sorting screen, and the grinding roller and the sorting screen are respectively limited in the grinding cavity and the sorting cavity.

[0008] The connecting ring plate is located in the grinding chamber, and a guide plate connected to the processing cylinder is provided on its outer edge. A plurality of through holes are evenly opened on the guide plate in the circumferential direction, and an air supply chamber connected to the grinding chamber is formed between the connecting ring plate, the guide plate and the processing cylinder.

[0009] Preferably, the sorting chamber, temporary storage chamber, grinding chamber and air supply chamber are distributed in sequence and interconnected.

[0010] Preferably, a driving guide rod is passed through the middle of the connecting ring plate, and the driving guide rod is connected to a fan located in the air supply chamber.

[0011] Preferably, the upper end of the temporary storage cylinder is open and inclined upward, and the middle part is through so that the grinding chamber and the sorting chamber are connected to each other.

[0012] Preferably, the guide plate is set at an inclination angle.

[0013] Preferably, the sorting screen is limitedly connected to the upper side of the processing cylinder and presents a conical cylinder structure with openings at both ends, with a plurality of through grooves uniformly formed on the circumference thereof. The sorting screen is connected to the driving guide rod through a connecting frame.

[0014] Preferably, the separation chamber is further provided with a secondary screen located inside the separation screen, and the secondary screen is also a conical cylinder structure and has a plurality of through grooves uniformly formed around the circumference.

[0015] Preferably, the size of the slots on the secondary screen is smaller than the size of the slots on the sorting screen.

[0016] Preferably, one end opening of the secondary screen is connected to the processing cylinder, and a guide channel communicating with the secondary screen is provided on the processing cylinder.

[0017] In addition, the present invention also provides an automated processing method for purple glutinous whole wheat flour, comprising the following steps: S1: The pre-cleaned purple glutinous wheat particles are introduced into a temporary storage barrel through a feeding channel, and then the wheat particles in the temporary storage barrel are dried by a processing component.

[0018] S2: After the wheat grains are dried, they are driven to fall into the grinding chamber, and then the grinding rollers, the connecting ring plates and the guide plates cooperate with each other to grind the wheat grains.

[0019] S3: After the wheat grains are ground, the crushed wheat grains are transported to the sorting chamber for screening. The crushed grains that meet the screening specifications of the sorting screen are guided out, and the crushed grains that do not meet the specifications fall back into the grinding chamber and continue to be ground until they meet the specifications.

[0020] In summary, this application includes at least one of the following beneficial technical effects: 1. The present invention provides a sorting chamber, a temporary storage chamber, a grinding chamber and an air supply chamber in the same processing cylinder, so that the wheat grains to be processed can complete the processing steps of air drying, grinding and sorting in the same equipment, effectively reducing the equipment volume and floor space, and lowering the equipment cost.

[0021] 2. The present invention forms a stable upward airflow through the coordinated use of the air supply chamber and the fan. The upward airflow drives the smaller purple glutinous wheat particles that have been ground and crushed to move upward to the sorting screen for screening. The smaller broken particles are screened again by the secondary screen after passing through the sorting screen, and the larger broken particles are blocked and fall back into the grinding chamber to be ground again. The air flow rate is controlled by adjusting the fan speed, and the sorting efficiency and grinding accuracy are balanced. The double screening of the sorting screen and the secondary screen ensures the consistency of the finished product fineness and the finished product yield of the purple glutinous whole wheat flour.

DETAILED DESCRIPTION

[0033] The following is combined with Figure 1 To the attached Figure 9 The embodiments of the present invention are described in detail.

[0034] The embodiment of the present application discloses an automated processing device and method for purple glutinous whole wheat flour. The present application is mainly used in the process of grinding purple glutinous wheat, and technically realizes the effect of automatically grinding purple glutinous wheat particles into purple glutinous whole wheat flour; in particular, during the grinding process, only one device is needed to complete the effect of sorting and grinding the purple glutinous wheat, effectively avoiding the problem of occupying a large space and increasing equipment costs when multiple devices are needed to process the purple glutinous wheat grains; and the present application also effectively improves the efficiency and effect of grinding and sorting the wheat grains through the mutual cooperation between the processing components.

[0035] Example 1: Reference Figure 1 and Figure 2 As shown, an automated processing device for purple glutinous whole wheat flour includes a processing drum 1 connected to a feed channel 10 and provided with a processing assembly 2 for grinding the wheat grains. During use, pre-cleaned purple glutinous wheat grains to be processed are introduced into the processing drum 1 through the feed channel 10. The grains are then processed by the processing assembly 2 to achieve an automated grinding effect. This allows the grains to be ground completely with just one device, effectively reducing the size of the equipment used to process the purple glutinous wheat grains, lowering both equipment costs and the equipment's footprint.

[0036] Reference Figures 2 to 4 As shown, the processing assembly 2 is used for grinding wheat grains; specifically, the processing assembly 2 includes: The temporary storage barrel 20 is limited to the processing barrel 1. The distance between the temporary storage barrel 20 and the processing barrel 1 allows the wheat grains to move upward with the airflow. The interior of the temporary storage barrel 20 is hollow to form a temporary storage chamber 21 which is connected to the feed channel 10. The two ends of the temporary storage barrel 20 divide the interior of the processing barrel 1 into a sorting chamber 22 and a grinding chamber 23.

[0037] The processing end 24 includes at least one grinding roller 240 and a sorting screen 241 . The grinding roller 240 and the sorting screen 241 are respectively located in the grinding chamber 23 and the sorting chamber 22 .

[0038] A connecting ring plate 25 is positioned within the grinding chamber 23. A guide plate 250, which is connected to the processing cylinder 1, is positioned within its outer edge. Guide plate 250 is circumferentially and evenly perforated with corresponding holes. An air supply chamber 251, communicating with the grinding chamber 23, is formed between the connecting ring plate 25, the guide plate 250, and the processing cylinder 1. As an optional embodiment, three grinding rollers 240 are circumferentially distributed on the inner wall of the processing cylinder 1.

[0039] During use, the cleaned wheat grains are introduced into the temporary storage tube 20 through the feed channel 10, and then air flow is blown into the processing tube 1. The air flow enters the grinding chamber 23 through several perforations on the guide plate 250, and is discharged from the grinding chamber 23 through the temporary storage tube 20 and then discharged from the sorting chamber 22. The flowing air flow is used to intervene in the water flow remaining on the wheat grains after pre-cleaning. After the wheat grains in the temporary storage chamber 21 are air-dried, they are introduced into the grinding chamber 23. By driving the relative displacement rotation between the connecting ring plate 25 and the grinding roller 240, the effect of grinding the wheat grains is achieved.

[0040] During the grinding process, the shear force exerted by the grinding roller 240 on the wheat grains causes the wheat grains to break until they are ground into powder. At this time, the air flow flowing through the air supply chamber 251 to the sorting chamber 22 drives the smaller-volume broken wheat grains in the grinding chamber 23 to rise to the sorting chamber 22 with the air flow. The smaller-volume wheat grains (i.e., wheat flour) among the rising broken wheat grains pass through the sorting screen 241 and are then discharged, while the larger-volume broken wheat grains are blocked by the sorting screen 241 and fall to the temporary storage tube 20. They are guided by the temporary storage tube 20 to fall back into the grinding chamber 23 and are ground again until the wheat grains are ground into the required specifications, completing the effect of grinding the purple glutinous wheat grains into whole wheat flour.

[0041] As an optional embodiment, an electric heating device can also be set in the processing box to make the air flow have a certain temperature when it is output, and the efficiency and effect of the drying process of the cleaned wheat grains can be accelerated by the flow of low-temperature air flow.

[0042] Reference Figures 2 to 4As shown, the sorting chamber 22 , the temporary storage chamber 21 , the grinding chamber 23 and the air supply chamber 251 are distributed in sequence and interconnected to form an air flow effect in the processing cylinder 1 .

[0043] Reference Figure 3 and Figure 4 As shown, to provide a continuous airflow within the processing drum 1, the connecting ring plate 25 is rotationally restrained on the guide plate 250, and a driving guide rod 26 is provided through its center. The driving guide rod 26 is connected to a fan 260 located within the air supply chamber 251. During operation, the rotation of the fan 260 creates a stable upward airflow within the air supply chamber 251, thereby air-drying the wheat grains. Simultaneously, the rotation of the fan 260 also synchronously drives the driving guide rod 26 and the connecting ring plate 25 to rotate, creating a relative displacement between the connecting ring plate 25 and the grinding roller 240. After the wheat grains within the temporary storage drum 20 fall onto the connecting ring plate 25, they are driven by the connecting ring plate 25 to move to the grinding roller 240 for grinding, thereby achieving a grinding process for the wheat grains.

[0044] Further, refer to Figure 5 and Figure 6 As shown, in order to allow the larger volume of broken wheat grains blocked by the sorting screen 241 to be reintroduced into the grinding chamber 23 for grinding, the upper end of the temporary storage cylinder 20 is open and inclined upward, and the middle part is through so that the grinding chamber 23 and the sorting chamber 22 are connected accordingly.

[0045] During use, the wheat grains rise with the air flow and are blocked by the sorting screen 241, then fall to the upper end of the temporary storage tube 20, and then fall back into the grinding chamber 23 along the opening of the temporary storage tube 20, thereby continuing to be ground, thereby increasing the fineness of the wheat grains ground into powder and the finished yield of wheat flour.

[0046] Reference Figure 5 and Figure 6 As shown, the guide plate 250 is set at an inclined angle so as to guide the scattered wheat grains to the connecting ring plate 25.

[0047] Reference Figure 5 As shown, the sorting screen 241 is limitedly connected to the upper side of the processing cylinder 1 and is a conical cylinder structure with openings at both ends. A number of through grooves 2410 are evenly formed on the circumference thereof for filtering out larger volumes of broken wheat grains. The sorting screen 241 is connected to the driving guide rod 26 through a connecting frame 2411.

[0048] During use, after the ground and crushed small particles in the grinding chamber 23 come into contact with the sorting screen 241 with the rising airflow, the rotation of the fan 260 will synchronously drive the driving guide rod 26 to rotate, and the driving guide rod 26 will drive the connecting frame 2411 and the sorting screen 241 to rotate. The larger broken particles among the particles moving upward with the rising airflow will be restricted by the size of the through slots 2410 on the sorting screen 241. At the same time, due to the rotation of the sorting screen 241, they are blocked outside the cylinder of the sorting screen 241. The rotating sorting screen 241 buffers part of the tendency of the larger particles to move upward with the rising airflow. At this time, the broken particles smaller than the size of the through slots 2410 on the sorting screen 241 enter the cylinder of the sorting screen 241, while the larger particles have their upward tendency blocked and buffered, and are affected by their own downward gravity and fall to the upper end of the temporary storage tube 20, and then fall back into the grinding chamber 23 to be ground again until the particles in the grinding chamber 23 can pass through the through slots 2410 on the sorting screen 241.

[0049] It should be noted that the rotation of the fan 260 will generate an upward airflow in the processing cylinder 1. Since the sorting effect of the wheat grains in the grinding chamber 23 is achieved by the rising airflow, after the wheat grains in the temporary storage cylinder 20 are dried, the overall output efficiency of the fan 260 should be reduced, so that the flow rate of the rising airflow is also reduced accordingly. The flow rate of the rising airflow should be maintained at a state where it will not drive the larger volume of intact and partially broken wheat grains to move upward, while allowing the smaller volume of particles to rise with the airflow.

[0050] The reduction in the rotation speed of the fan 260 allows the volume of the ground and crushed wheat grains in the grinding chamber 23 to be reduced accordingly as they move upward with the rising airflow, thereby effectively controlling the processing accuracy of the wheat grain grinding. However, the reduction in the rotation speed of the fan 260 will also simultaneously lead to a reduction in the rotation speed of the sorting screen 241, making it easier for the rising wheat grains to be squeezed into the sorting screen 241 with the rising airflow.

[0051] Based on the above, refer to Figure 5 As shown, in order to improve the processing accuracy of whole wheat flour, a secondary screen 27 located in the sorting screen 241 is further provided in the sorting chamber 22. The secondary screen 27 is also a conical cylinder structure and has a number of through grooves 2410 evenly formed in the circumference. Through the double screening of the sorting screen 241 and the secondary screen 27, the accidental entry of larger particles is effectively avoided, and the screening accuracy is improved. Through the mutual cooperation between the sorting screen 241 and the secondary screen 27, the problem of decreased sorting efficiency caused by the reduction in the rotation speed of the fan 260 is alleviated to a certain extent, making the operation of the overall equipment more stable and reliable, thereby improving the grinding accuracy of the wheat grains.

[0052] Further, refer to Figure 5As shown, as an optional embodiment, the size of the through slot 2410 on the secondary screen 27 is preferably smaller than the size of the through slot 2410 on the sorting screen 241, so as to further improve the screening effect, and can effectively block the passage of larger particles squeezed into the cylinder of the sorting screen 241, thereby ensuring that only fine particles that meet the requirements can be discharged and collected.

[0053] Reference Figure 5 As shown, to facilitate the discharge of wheat grains ground into flour from the processing drum 1, the secondary sieve 27 is open at one end, connected to the processing drum 1. A guide channel 11 is provided through the processing drum 1 and communicates with the secondary sieve 27. During use, the crushed wheat grains, which have been screened by both the sorting sieve 241 and the secondary sieve 27, are guided by the airflow between the secondary sieve 27 and the processing drum 1. After entering the secondary sieve 27, the airflow tends to flow outward along the guide channel 11, thereby simultaneously discharging the smaller purple glutinous wheat grains (i.e., ground whole wheat flour) between the secondary sieve 27 and the processing drum 1 for easy collection by staff.

[0054] Example 2: Reference Figures 5 to 7 As shown, based on the first embodiment, before the wheat grains are ground, they are usually washed or soaked in water to remove impurities, and then the wheat grains after impurity removal and drying are put into the equipment for grinding, so as to improve the output quality of purple glutinous whole wheat flour. In order to complete the effect of air-drying the wheat grains after pre-cleaning; specifically, the temporary storage cylinder 20 includes an installation ring plate 200 and a guide ring plate 201 spaced apart in the upper and lower parts. The installation ring plate 200 is open and inclined upward and is connected to the guide channel 11. The guide ring plate 201 is an inclined structure The mounting ring plate 200 and the guide ring plate 201 are provided with a connecting tube 203, and a temporary storage chamber 21 is formed between the mounting ring plate 200, the guide ring plate 201 and the connecting tube 203. Both ends of the connecting tube 203 are connected to correspond to the openings of the grading screen, so that the grinding chamber 23 and the sorting chamber 22 are connected, so that the broken wheat particles blocked by the sorting screen 241 can fall back into the grinding chamber 23.

[0055] In order to facilitate the introduction of the dried wheat grains in the temporary storage chamber 21 into the grinding chamber 23, a plurality of through grooves 204 are formed circumferentially on the connecting tube 203. Sliding resistance plates 28 are slidably inserted into the corresponding through grooves 204 on the connecting tube 203. A driven guide plate 280 is extended from the sliding resistance plate 28 into the temporary storage chamber 21. The driven guide plate 280 is connected to a mounting seat 281. A rotating pin 282 is passed through the mounting seat 281. The rotating pin 282 is rotationally limited to the mounting seat 281 by a torsion spring. A limit plate 283 is further connected to the rotating pin 282 to limit the deflection amplitude of the connected rotating pin 282.

[0056] During use, the pre-treated and cleaned wheat grains are introduced into the temporary storage chamber 21 through the feed channel 10, and the fan 260 is activated to form an airflow in the processing cylinder 1. The airflow passes through the air supply chamber 251, the grinding chamber 23 and the sorting chamber 22, and is discharged outward through the guide channel 11. When the airflow flows through the gap between the guide ring plate 201 and the mounting ring plate 200 and the processing cylinder 1, it escapes into the temporary storage chamber 21 through the several air holes 202 on the guide ring plate 201. After the airflow passes through the several wheat grains in the temporary storage chamber 21, the moisture in the wheat grains is driven to evaporate faster, thereby achieving the effect of drying the pre-treated and cleaned wheat grains.

[0057] After the wheat grains are dried, the driven guide plate 280 and the sliding resistance plate 28 are driven to slide along the connected through groove 204, partially leaking the through groove 204, so that the temporary storage chamber 21 is connected to the grinding chamber 23 and the sorting chamber 22 through the air vent 202 and the through groove 204. At this time, due to the guidance of the guide ring plate 201 and the influence of the gravity of the wheat grains themselves, the wheat grains in the temporary storage chamber 21 tend to slide along the inclined guide ring plate 201 toward the through groove 204, so that the wheat grains fall from the through groove 204 to the connecting ring plate 25, and then are driven by the rotating connecting ring plate 25 to move to the grinding roller 240 for extrusion and grinding. The smaller crushed wheat grains ground and crushed by the grinding roller 240 are driven upward by the air flow to the sorting chamber 22, and the smaller particles that meet the specifications enter the secondary screen 27 and are guided and discharged, while the larger particles are blocked and fall back to the connecting ring plate 25 to be ground again until they meet the requirements.

[0058] Further, refer to Figures 6 to 9 As shown, since the wheat grains need to be pre-treated and cleaned, their own weight will increase after being soaked in water, while the weight of the wheat grains after drying will decrease accordingly due to the loss of water. Based on the above, in order to drive the sliding resistance plate 28 to slide, so as to introduce the wheat grains in the temporary storage chamber 21 into the grinding chamber 23 after drying, a bending pressure plate 29 is commonly connected between any two adjacent driven guide plates 280. The bending pressure plate 29 is connected to an extension guide rod 290 passing through the guide ring plate 201, and several extension guide rods 290 are commonly connected to a driven panel 291 located in the grinding chamber 23.

[0059] In the initial state, the sliding resistance plate 28 normally slides within the corresponding through groove 204 to close the temporary storage cavity 21. At this time, the bent section at the bottom of the bent pressure plate 29 is spaced a distance from the guide ring plate 201, and the driven guide plate 280 and the mounting seat 281 are spaced a distance from the guide ring plate 201. At the same time, the rotating pin 282 and the limit plate 283 are deflected by a certain amplitude, so that the limit plate 283 is inclined and forms a certain angle with the driven guide plate 280, and the limit plate 283 is in contact with the guide ring plate 201.

[0060] During use, after the pre-treated wheat grains are introduced into the temporary storage chamber 21, the falling wheat grains will first fall onto one of the driven guide plates 280 and exert a downward force on the driven guide plate 280, driving the driven guide plate 280, the sliding resistance plate 28, the mounting seat 281, the rotating pin 282, the limit plate 283 and the bending pressure plate 29 to move further downward until the bending pressure plate 29 abuts against the guide ring plate 201, and the limit plate 283 and the connected rotating pin 282 further move downward. The rotation tilts and drives the connected torsion spring to be further stressed. The wheat grains falling into the temporary storage chamber 21 are affected by their own gravity and naturally gather along the guide ring plate 201 in the direction close to the connecting tube 203, thereby being pressed on the bending pressure plate 29, driving the bending section at the bottom end of the bending pressure plate 29 to abut against the guide ring plate 201, so as to limit the upward movement and reset of the driven guide plate 280, the sliding resistance plate 28, the mounting seat 281, the rotating pin rod 282, the limit plate 283 and the bending pressure plate 29 as a whole.

[0061] When the pre-cleaned wheat grains need to be dried in the initial stage, the output efficiency of the fan 260 increases, causing the air flow velocity flowing in the processing cylinder 1 to increase. After the air flow rises to the grinding chamber 23 and contacts the driven panel 291, there is a tendency to drive the driven panel 291 to move upward with the air flow. The bent pressure plate 29, the extended guide rod 290 and the driven panel 291 are restricted by the accumulated wheat grains in the temporary storage cylinder 20 and cannot move upward, so that the torsion spring is always in a compressed state.

[0062] After the wheat grains in the temporary storage tube 20 are dried, the overall weight of the wheat grains decreases due to the loss of their own moisture, and the downward pressure applied to the bending pressure plate 29, the driven guide plate 280, the sliding resistance plate 28, the mounting seat 281, the rotating pin 282 and the limit plate 283 as a whole is reduced. At this time, under the combined action of the rising air flow and the return thrust of the torsion spring, the bending pressure plate 29, the driven guide plate 280, the sliding resistance plate 28, the mounting seat 281, the rotating pin 282, the limit plate 283, the extension guide rod 290 and the driven panel 291 are driven to move upward as a whole, thereby opening the through slot 204 on the connecting tube 203, so that the wheat grains fall into the grinding chamber 23. After the wheat grains in the temporary storage chamber 21 have completely fallen, the output efficiency of the control fan 260 is reduced, thereby sorting the ground wheat grains.

[0063] Further, refer to Figure 6 and Figure 7As shown, as an optional embodiment, in order to improve the drying efficiency of the wheat grains in the temporary storage chamber 21, the connecting cylinder 203 is also connected to the driving guide rod 26 through the connecting frame 2411. At this time, the connecting cylinder 203 is rotatably connected to the mounting ring plate 200 and the guide ring plate 201, and a plurality of extended guide rods 290 are slidably passed through the guide ring plate 201. At the same time, a closed ring plate (not shown in the figure) slidably passed through the guide ring plate 201 is commonly connected between the plurality of extended guide rods 290 to avoid leakage of wheat grains during rotation.

[0064] During use, after the fan 260 is activated, it rotates while driving the connecting tube 203 by driving the guide rod 26. The rotation of the connecting tube 203 drives all the connected sliding resistance plates 28, driven guide plates 280, mounting seats 281, rotating pins 282, limiting plates 283, bending pressure plates 29, extending guide rods 290, closed ring plates and driven panels 291 to rotate synchronously, so that the limiting plates 283 and the sliding resistance plates 28 drive the wheat grains in the temporary storage chamber 21 to shift, thereby increasing the contact area between the wheat grains and the airflow and improving the efficiency of driving the wheat grains to dry.

[0065] In addition, the present invention also provides an automated processing method for purple glutinous whole wheat flour, comprising the following steps: S1: The pre-cleaned purple glutinous wheat grains are introduced into the temporary storage tube 20 through the feeding channel 10, and then the wheat grains in the temporary storage tube 20 are dried by the processing component 2.

[0066] S2: After the wheat grains are dried, they are driven to fall into the grinding chamber 23 and then ground through the cooperation between the grinding roller 240, the connecting ring plate 25 and the guide plate 250.

[0067] S3: After the wheat grains are ground, the crushed wheat grains are transported to the sorting chamber 22 for screening, wherein the crushed grains that meet the screening specifications of the sorting screen 241 are guided out, and the crushed grains that do not meet the specifications fall back into the grinding chamber 23 and continue to be ground until they meet the specifications.

[0068] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as exemplary and non-restrictive.

[0069] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
