Description

Technical Field

[0001] The invention relates to the technical field of grain processing, and in particular to an experimental wheat flour mill. Background Art

[0002] In the field of agricultural research and food processing, experimental wheat mills are important tools for wheat quality analysis, flour characteristics research and new product development. Traditional laboratory mills are usually large in size and complex in structure, mainly composed of a feeding system, a screening system, a grinding system and a discharging system.

[0003] Although these devices can meet basic grinding needs, they have many inconveniences in actual use. Traditional laboratory mills need to accommodate multiple functional modules (such as grinding, screening, etc.), so they are large in size and occupy a lot of space. This not only limits their flexible layout in the laboratory, but also makes it difficult to adapt to different experimental needs and site conditions. For some small laboratories or temporary experimental sites, the application of such equipment is greatly restricted, and it also increases the difficulty of transportation and installation.

[0004] Wheat raw materials are often mixed with impurities of varying sizes, such as stones, dust, and plant residues. These impurities not only affect the quality of the final flour, but may also damage the internal components of the mill and shorten the life of the equipment. In order to remove these impurities, traditional mills usually need to go through multiple screening processes. Each screening process requires an independent screening mechanism, such as a vibrating screen, air separator, etc. This multi-stage screening system further increases the size of the entire equipment, increasing costs and maintenance difficulties. Summary of the invention

[0009] Optionally, it also includes: The grinding disc is movably arranged and has a grinding plane. After the grinding disc moves, the grinding plane rolls against the grinding roller or cancels the rolling abutment.

[0010] Optionally, the grinding disc further has an inclined surface, which is located on the peripheral side of the grinding plane and is used to guide the material to the grinding plane; The first discharge port is located at a side of the second cavity away from the connecting seat and faces the inclined surface; The cross section of the second material cavity parallel to the length direction is in a truncated cone shape, and the diameter of the end close to the connecting seat is smaller than the diameter of the end away from the connecting seat.

[0011] Optionally, the first material chamber has a guide portion, which is located at one end of the first material chamber away from the fan, and the guide portion rises smoothly in a curve from close to the fan to away from the fan. After passing through the guide portion, part of the material falls into the outlet channel, and the other part enters the second material chamber.

[0012] Optionally, it also includes: A material discharge tray, the material discharge tray is rotatably arranged and has a second material inlet and a second material outlet, the first mounting seat and the second mounting seat are both arranged on the material discharge tray and located below the material discharge tray, and the second material outlet is communicated with the first material inlet; The sieve plate is detachably arranged on the lower material plate and is located above the lower material plate, and the sieve plate has sieve holes.

In addition, by precisely controlling the wind force, foreign matter in the wheat can be effectively removed to ensure the purity of the final product, while also laying a solid foundation for subsequent processing steps. This compact screening device is not only suitable for small-scale experimental environments in scientific research institutions, but can also bring certain inspiration to small-scale flour production for commercial purposes.

DETAILED DESCRIPTION

[0020] In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the specific implementation methods of the present invention will be described below with reference to the accompanying drawings. Obviously, the accompanying drawings described below are only some embodiments of the present invention. For ordinary technicians in this field, other drawings and other implementation methods can be obtained based on these drawings without creative work.

In addition, in order to simplify the drawings and facilitate understanding, in some figures, only one of the parts with the same structure or function is schematically shown, or only one of them is marked. In this article, "one" not only means "only one", but also means "more than one", and "several" includes "two" and "more than two".

[0022] In this document, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0023] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0024] Reference Figure 1~Figure 5 An experimental wheat flour mill is proposed, comprising: a first mounting seat 1, the first mounting seat 1 having a first material chamber 101, the first material chamber 101 having a first material inlet 102; a second mounting seat 2, the second mounting seat 2 having a second material chamber 201, the second material chamber 201 being connected to the first material chamber 101, and the second material chamber 201 having a first material outlet 202; a connecting seat 3, the connecting seat 3 is located between the first mounting seat 1 and the second mounting seat 2, and has a connecting port 301, the connecting port 301 is used to connect the first material chamber 101 and the second material chamber 201, and the connecting seat 3 also has a miscellaneous outlet 302; a fan 4, the fan 4 is arranged in the first material chamber 101, and is located on one side of the first material inlet 102, and the fan 4 faces the first material chamber 101 and the second material chamber 201.

[0025] In this embodiment, a compact installation method of the screening component is proposed to address the problem that the conventional experimental wheat mill is bulky and occupies a large area due to the need to accommodate multiple functional modules. This design not only improves the utilization rate of the laboratory space, but also ensures the effective implementation of the grinding process.

[0026] Therefore, the first mounting seat 1, the second mounting seat 2 and the connecting seat 3 are designed. These components can be designed in an integrated manner to simplify the structure, or in a split and detachable form to enhance the convenience and flexibility of maintenance.

[0027] The first mounting seat 1 is designed with a first cavity 101, which is mainly used to receive the wheat raw material to be processed. In order to maximize the use of space and optimize the material flow path, the first cavity 101 is set to a cylindrical shape, and its axis is arranged horizontally. Such a layout helps to reduce the overall height requirement of the equipment while maintaining good material transmission efficiency. Wheat enters the first cavity 101 through the first inlet 102 located above. The second mounting seat 2 includes a second cavity 201, which also adopts a cylindrical design and a horizontal axis setting. It is connected to the first cavity 101 through a connecting port 301, so that the wheat after preliminary cleaning can smoothly transition to the next stage under the action of wind. In this process, the airflow generated by the fan 4 is used for air selection operation, which effectively separates those impurities (such as stones) that are close in size but have a higher density, so that they fall into the impurity outlet 302, and the wheat particles enter the second cavity 201. The function of the connecting seat 3 is to ensure a stable connection between the first mounting seat 1 and the second mounting seat 2. Whether an integrated or modular design is adopted, it is necessary to ensure that the entire system is well sealed and the components are seamlessly connected to form a continuous workflow. Through the above-mentioned innovative design ideas, that is, using the horizontal space expansion instead of the traditional vertical stacking method, this solution successfully reduces the overall height requirements of the wheat mill, thereby greatly improving its flexibility in placement in the laboratory. In addition, by precisely controlling the size of the wind force, foreign matter in the wheat can be effectively removed to ensure the purity of the final product, while also laying a solid foundation for subsequent processing steps. This compact screening device is not only suitable for small-scale experimental environments in scientific research institutions, but can also bring certain inspiration to small-scale flour production for commercial purposes.

[0028] Furthermore, in order to further improve the air separation efficiency and ensure that the material can enter the second material chamber 201 more smoothly, a guide part 10 is specially introduced in the design. The design of this component is to optimize the airflow path and the material flow trajectory, so that the wheat particles and impurities can be effectively separated under the action of wind. The main function of the guide part 10 is to guide the direction of the airflow through its specific geometric shape and control the movement trajectory of the material (including wheat and impurities such as stones mixed therein). When the mixture passes through the guide part 10 under the impetus of the airflow generated by the fan 4, particles of different masses will be affected to different degrees. The guide part 10 adopts an inclined surface 902 or a curved surface structure (a curved surface is adopted in this scheme). This design helps to form a smooth transition area, prompting the material to move along a preset path. When the wheat raw material containing impurities is blown out from the first material chamber 101 and moves along the guide part 10, the lighter wheat particles will rise along the guide surface under the action of wind, pass through the guide part 10 and pass over the top of the impurity discharge channel 302 according to the parabolic trajectory, and finally fall into the second material chamber 201 for subsequent processing. In contrast, those foreign objects with higher density, relatively similar volume but heavier weight (such as small stones) will have a shorter parabolic path due to their greater gravity, and fall into the impurity discharge channel 302 set below and be discharged. By reasonably setting the guide part 10, the separation accuracy in the air selection process can be significantly improved, and the loss of high-quality wheat can be reduced while effectively removing most impurities.

[0029] Furthermore, the first mounting seat 1 and / or the second mounting seat 2 has a mounting groove 5, which is semicircular and has a horizontal axis, and also includes: a grinding roller 6, which is rotatably arranged in the mounting groove 5, and the length of the grinding roller 6 is equal to or less than the length of the mounting groove 5.

[0030] In this embodiment, in order to further optimize the space utilization and reduce the overall volume of the equipment, and in order to take into account the grinding efficiency, better control the flour particle size and uniformity, and meet the diverse requirements for the characteristics of the finished product in different experiments or production processes, a mounting groove 5 specifically used for mounting the grinding roller 6 is provided on the first mounting seat 1 and the second mounting seat 2. The design of these mounting grooves 5 is special in that their axes are also arranged horizontally, which means that the rotation axis of the grinding roller 6 installed therein is also horizontal. Such a layout strategy greatly reduces the vertical height requirements of the entire device, making the machine more compact and more suitable for application scenarios with limited space such as laboratories. Each set of grinding rollers 6 is precisely embedded in their respective mounting grooves 5, and the length of the grinding roller 6 is equal to or less than the length of the mounting groove 5. Good mechanical stability is ensured without additionally increasing the external dimensions, saving space in the horizontal direction. In addition, considering the convenience of maintenance and the possible need for future technical upgrades, all grinding components can be designed to be easily disassembled and replaced. This is not only convenient for daily cleaning and maintenance, but also allows the user to flexibly adjust or replace worn parts according to actual usage conditions, thereby extending the service life of the entire system. In order to prevent wheat particles from adhering to the surface of the grinding roller 6 and affecting the normal grinding process, a scraping portion 501 is designed in the mounting groove 5. The scraping portion 501 contacts the circumferential side of the grinding roller 6 and is used to scrape off the material adhering to the outer wall of the grinding roller 6, so that the wheat adhering to the surface of the grinding roller 6 will be scraped off during the rotation of the grinding roller 6.

[0031] In summary, by introducing the horizontally arranged grinding roller 6 and its matching mounting groove 5, not only the goal of miniaturization of the equipment is successfully achieved, but also the requirements of high efficiency, ease of use and maintainability are taken into account.

[0032] Furthermore, the second mounting seat 2 is a split structure, having a seat body 203 and a cylinder body 204, wherein the cylinder body 204 has a second material chamber 201, and the cylinder body 204 is rotatably set on the seat body 203; it also includes: a first gear 7, which is set on the grinding roller 6 of the second mounting seat 2 and is coaxial with the grinding roller 6; a second gear 8, which is set on the cylinder body 204 and is coaxial with the cylinder body 204, and the second gear 8 is meshingly connected with the first gear 7.

[0033] Considering that wheat itself has a certain degree of adhesion, the design of the fan 4 can also effectively prevent wheat from adhering to the first material chamber 101 or the second material chamber 201. At the same time, because the fan 4 is arranged in the first material chamber 101, it is relatively far away from the second material chamber 201, and there is a guide part 10 between the first material chamber 101 and the second material chamber 201, and the guide part 10 will block part of the wind force. In order to further prevent wheat from accumulating in the second material chamber 201, a special design is made: 1. The second mounting seat 2 is a split structure, having a seat body 203 and a cylinder body 204. The seat body 203 and the cylinder body 204 are separately arranged. The cylinder body 204 contains the second material chamber 201, and the cylinder body 204 can rotate on the seat body 203, and the axis of rotation is parallel to the axis of the first material chamber 101, so that when the wheat material enters the second material chamber 201, the wheat particles will roll in the material chamber under the rotation of the cylinder body 204. This rolling action helps the material to be more evenly exposed to the wind force and promotes the effective separation of impurities and wheat. At the same time, since the material is in a moving state, the possibility of its adhesion to the wall of the material chamber is reduced.

[0034] In order to realize the rotation of the above-mentioned cylinder 204, the rotation of the grinding roller 6 is utilized, which reduces the use of driving devices such as motors, saves space, reduces the overall weight, saves costs, and reduces the difficulty of maintenance. Specifically, the grinding roller 6 rolls against the grinding surface 901 of the grinding disc 9. After the grinding roller 6 rotates, it drives the first gear 7 to rotate. After the first gear 7 rotates, it drives the second gear 8 to rotate. The rotation of the second gear 8 realizes the follow-up rotation of the cylinder 204.

[0035] 2. The cross section of the second material chamber 201 parallel to the length direction is truncated cone-shaped, and the diameter of the end close to the connecting seat 3 is smaller than the diameter of the end away from the connecting seat 3. This method allows the wheat material entering the second material chamber 201 to roll forward along the gradually increasing space, increasing the power of the material to move toward the discharge port. As the space increases, the space for air flow also increases, which helps to distribute the wind force more evenly on the surface of the material and improves the wind selection efficiency. The truncated cone structure reduces the dead corner area that may appear in the traditional rectangular or circular material chamber, reducing the risk of material accumulation. The rotatable cylinder 204 and the truncated cone-shaped material chamber improve the fluidity of the material in the second material chamber 201. Enhance the performance of the entire system.

[0036] Further, the grinding disc 9 is arranged to move, and after the grinding disc 9 moves, the grinding plane 901 rolls against or cancels the rolling abutment with the grinding roller 6. The material discharge plate 11 is arranged to rotate, and has a second material inlet 1101 and a second material outlet 1102. The first mounting seat 1 and the second mounting seat 2 are both arranged on the material discharge plate 11 and are located below the material discharge plate 11. The second material outlet 1102 is connected to the first material inlet 102.

[0037] In this embodiment, in order to better distribute the wheat material from the first discharge port 202 to the grinding plane 901 more smoothly, a special design is made: 1. The feed tray 11 is designed to rotate around its axis. When the feed tray 11 rotates, it drives the first mounting seat 1 and the second mounting seat 2 to rotate together. This linkage mechanism ensures that the two grinding rollers 6 and the first discharge port 202 move with the feed tray 11. Since the first discharge port 202 also moves with the rotation of the feed tray 11, it can evenly spread the material along the circumferential boundary of the grinding plane 901. The advantage of this is that it avoids the concentrated accumulation of materials in a certain area, thereby ensuring the uniform distribution of materials during the grinding process. When the two grinding rollers 6 rotate with the mounting seat, they can push the wheat material on the grinding plane 901 or directly perform preliminary grinding. This dynamic operation helps to improve processing efficiency and further promotes the uniform distribution of materials.

[0038] 2. During the wheat screening stage, the grinding disc 9 can be moved to a position away from the grinding roller 6 by a mechanical device, thus forming a larger space. This allows the material discharged from the wheat discharge port to enter the grinding plane 901 more easily without obstruction. Once it is found that a large amount of wheat material has accumulated in the peripheral area on the grinding plane 901, the grinding disc 9 can be moved gradually closer to the grinding roller 6. In this way, the rotation of the grinding roller 6 can effectively push these materials to the center position to achieve a more uniform distribution. When the wheat material has been distributed more evenly, the grinding disc 9 can continue to be moved to a position closer to the grinding roller 6 to achieve the best grinding effect. At this time, the grinding roller 6 will apply sufficient pressure to the grinding disc 9 to perform efficient grinding operations.

[0039] 3. The grinding disc 9 is provided with an inclined surface 902 on the side of its grinding plane 901. The function of the inclined surface 902 is to guide the wheat material discharged from the first discharge port 202 to the middle of the grinding plane 901. Such a design helps the material to reach the core area that needs to be processed more quickly. The design of the inclined surface 902 also helps to play a certain shielding role during the grinding process, preventing the wheat material from moving out of the grinding plane 901 due to the thrust of the grinding roller 6. At the same time, the inclined surface 902 is also conducive to the natural inward gathering of the material during the rolling process and keeping it in the grinding area.

[0040] Furthermore, the sieve plate 12 is detachably disposed on the lower material tray 11 and is located above the lower material tray 11 , and the sieve plate 12 has sieve holes.

[0041] In this embodiment, the sieve plate 12 is designed to be easily removed from the lower material plate 11. This design facilitates regular cleaning of impurities and allows the replacement of sieves of different apertures according to different material properties. The sieve plate 12 is mounted on the lower material plate 11 and rotates with the rotation of the lower material plate 11. This synchronous movement helps to evenly distribute the material and improve the screening effect. The aperture of the sieve hole is slightly larger than the average particle size of wheat, which can effectively block those impurities with a long length or large volume (such as straw, weeds, etc.), so that they remain on the sieve, while wheat particles can pass through the sieve hole into the subsequent processing stage. As the sieve plate 12 rotates, the material will be more evenly distributed on the sieve under the action of centrifugal force. This not only speeds up the screening speed, but also ensures that the material is more comprehensively screened. The design of the detachable sieve plate 12 makes cleaning simple and quick, and the sieve plate 12 can be easily removed and impurities can be removed without complicated maintenance steps, simplifying daily operations. By introducing the detachable sieve plate 12 and combining it with the rotation mechanism of the lower material plate 11, the present design not only achieves efficient material screening, but also enhances the flexibility and maintenance convenience of the system.

[0042] Furthermore, the grinding disc 9 is detachably arranged, and after the grinding disc 9 moves, it abuts against the outer wall of the grinding roller 6 or is lower than the outlet channel 302. In this embodiment, the detachable arrangement of the grinding disc 9 also provides convenience for collecting wheat flour after wheat grinding.

[0043] Furthermore, it also includes: a body 13, in which the above components are installed, the body 13 has a feed port 1301, and the feed port 1301 faces the sieve plate 12; a collecting trough 14, which is detachably arranged in the body 13 and located below the outlet channel 302.

[0044] In this embodiment, the collecting tank 14 is installed below the impurities outlet 302, and is used to collect impurities with a volume close to that of wheat separated from the impurities outlet 302. The collecting tank 14 adopts a detachable design, which is convenient for users to regularly clean the impurities therein. This design not only simplifies the maintenance process, but also ensures the long-term stable operation of the equipment. Preferably, the body 13 is wrapped with efficient sound insulation materials inside and outside. For example, sound-absorbing cotton or sound-insulating foam is laid on the inner side of the shell, which can effectively absorb and isolate the noise generated when the equipment is running. The feeding port 1301 is located at the top of the first material chamber 101, and the size is moderate, which is convenient for users to manually add materials and avoid dust overflow caused by excessive openings. Preferably, an observation window can be opened on the side wall of the body 13 to observe the grinding progress inside the body 13, and a door body 15 that can be pulled open can be designed. After the door body 15 is pulled open, the internal device can be disassembled and replaced. It can also be equipped with a dust cover that can be opened and closed, which can be closed when no material is added to prevent dust from entering the body 13. All components, including the grinding roller 6, the sieve plate 12, the discharge plate 11, the drum 204 rotating device and the collecting tank 14 are rationally integrated into a compact and efficient machine body 13 to form a complete material handling system.

Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
