Description

Technical Field

[0001] This invention relates to the field of grain processing technology, specifically to an experimental wheat mill. Background Technology

[0002] In agricultural research and food processing, laboratory wheat mills are essential tools for wheat quality analysis, flour property research, and new product development. Traditional laboratory mills are typically large and complex, mainly consisting of a feeding system, a screening system, a grinding system, and a discharge system.

[0003] While these devices can meet basic grinding needs, they present numerous inconveniences in practical use. Traditional laboratory grinding mills, needing to accommodate multiple functional modules (such as grinding and screening), are large in size and occupy a significant amount of space. This not only limits their flexible placement in the laboratory and makes them difficult to adapt to different experimental needs and site conditions, but also greatly restricts their application in small laboratories or temporary experimental sites, increasing the difficulty of transportation and installation.

[0004] Wheat raw materials often contain impurities of varying sizes, such as stones, dust, and plant residues. These impurities not only affect the quality of the final flour but can also damage the internal components of the mill, shortening the equipment's lifespan. To remove these impurities, traditional mills typically require multiple screening processes. Each screening process necessitates an independent screening mechanism, such as a vibrating screen or an air classifier. This multi-stage screening system further increases the overall size of the equipment, raising costs and maintenance complexity. Summary of the Invention

[0005] This invention proposes an experimental wheat mill that solves the problems of traditional laboratory mills, which are usually large in size and complex in structure, resulting in poor adaptability and difficulty in moving and transporting them.

[0006] The technical solution of the present invention is as follows: An experimental wheat milling machine, comprising:

[0007] A first mounting base, the first mounting base having a first material cavity, the first material cavity having a first inlet;

[0008] The second mounting base has a second material cavity that communicates with the first material cavity and has a first material outlet.

[0009] A connecting seat is located between the first mounting seat and the second mounting seat, and has a communication port for connecting the first material chamber and the second material chamber. The connecting seat also has a waste outlet.

[0010] A blower is disposed in the first material chamber and located on one side of the first inlet, the blower facing the first material chamber and the second material chamber.

[0011] Optionally, the first mounting base and / or the second mounting base has a mounting groove, the mounting groove being semi-circular and having a horizontally arranged axis, and further includes:

[0012] A grinding roller is rotatably disposed within the mounting groove, and the length of the grinding roller is equal to or less than the length of the mounting groove.

[0013] Optionally, the second mounting base is a split structure, having a base body and a cylindrical body, wherein the cylindrical body has a second material chamber, and the cylindrical body is rotatably mounted on the base body; it also includes:

[0014] A first gear is mounted on the grinding roller of the second mounting base and is coaxial with the grinding roller;

[0015] The second gear is mounted on the cylinder and is coaxial with the cylinder. The second gear meshes with the first gear.

[0016] Optionally, it also includes:

[0017] A grinding disc, which is movable and has a grinding surface, wherein after the grinding disc is moved, the grinding surface rolls into contact with the grinding roller or cancels rolling contact.

[0018] Optionally, the grinding disc further has an inclined surface located on the periphery of the grinding plane for guiding the material to the grinding plane;

[0019] The first discharge port is located on the side of the second material cavity away from the connecting seat and faces the inclined surface;

[0020] The second material cavity has a frustum-shaped cross section parallel to its length direction, with the diameter at the end near the connecting seat being smaller than the diameter at the end away from the connecting seat.

[0021] Optionally, the first material chamber has a guide section located at one end of the first material chamber away from the blower, and the guide section rises smoothly in a curve from near the blower to away from the blower. After passing through the guide section, part of the material falls into the discharge channel, and the other part enters the second material chamber.

[0022] Optionally, it also includes:

[0023] The feeding tray is rotatably configured and has a second inlet and a second outlet. The first mounting base and the second mounting base are both disposed on the feeding tray and located below the feeding tray. The second outlet communicates with the first inlet.

[0024] A sieve disc, which is detachably mounted on the feed tray and located above the feed tray, has sieve holes.

[0025] Optionally, the mounting groove has a scraper that contacts the circumference of the grinding roller to scrape off material adhering to the outer wall of the grinding roller.

[0026] Optionally, the grinding disc is detachable, and after being moved, the grinding disc abuts against or is lower than the outer wall of the grinding roller.

[0027] Optionally, it also includes:

[0028] The machine body has a feeding port facing the screen plate;

[0029] A collection trough is detachably disposed within the machine body and located below the waste outlet.

[0030] The working principle and beneficial effects of this invention are as follows:

[0031] In this invention, the first mounting base is designed with a first material chamber, which is mainly used to receive the wheat raw material to be processed. To maximize space utilization and optimize the material flow path, the first material chamber is set in a cylindrical shape with its axis arranged horizontally. This layout helps to reduce the overall height requirement of the equipment while maintaining good material transfer efficiency. Wheat enters the first material chamber through the first inlet located at the top. The second mounting base contains a second material chamber, which also adopts a cylindrical design and a horizontal axis. It is connected to the first material chamber through a connecting port, allowing the wheat, after initial cleaning, to smoothly transition to the next stage under the action of wind. During this process, airflow generated by a fan is used for air separation, effectively separating impurities (such as stones) that are similar in size but have a higher density, causing them to fall into the impurity outlet, while the wheat particles enter the second material chamber. The connecting base ensures a stable connection between the first and second mounting bases. Whether using an integrated or modular design, it is necessary to ensure good sealing of the entire system and seamless connection between the components to form a continuous workflow. By employing the innovative design concept of horizontal spatial expansion instead of traditional vertical stacking, this solution successfully reduces the overall height requirement of the wheat mill, thereby significantly improving its flexibility for placement in laboratory settings. Furthermore, precise control of airflow effectively removes foreign matter from the wheat, ensuring the purity of the final product and laying a solid foundation for subsequent processing steps. This compact screening device is not only suitable for small-scale experimental environments in research institutions but can also offer insights for small-scale flour production in commercial applications.

[0039] To more clearly illustrate the technical solutions in the embodiments of the present invention or the prior art, the specific implementation methods of the present invention will be described below with reference to the accompanying drawings. Obviously, the drawings described below are merely some embodiments of the present invention. For those skilled in the art, other drawings and other implementation methods can be obtained based on these drawings without any creative effort.

[0040] To keep the drawings concise, each drawing only schematically shows the parts relevant to the invention; these do not represent the actual structure of the product. Furthermore, for ease of understanding, in some drawings, only one of components with the same structure or function is schematically shown, or only one is labeled. In this document, "one" not only means "only one," but can also mean "more than one," and "several" includes "two" and "more than two."

[0041] In this document, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0042] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0043] Reference Figures 1-5 An experimental wheat mill is proposed, comprising: a first mounting base 1 having a first material chamber 101 having a first inlet 102; a second mounting base 2 having a second material chamber 201 communicating with the first material chamber 101 having a first outlet 202; a connecting base 3 located between the first mounting base 1 and the second mounting base 2, having a connecting port 301 for communicating with the first material chamber 101 and the second material chamber 201, and the connecting base 3 also having a waste outlet 302; and a fan 4 disposed in the first material chamber 101 and located on one side of the first inlet 102, the fan 4 facing the first material chamber 101 and the second material chamber 201.

[0044] This embodiment proposes a compact installation method for the screening components to address the problem of conventional experimental wheat mills being bulky and occupying a large area due to the need to accommodate multiple functional modules. This design not only improves the utilization rate of laboratory space but also ensures the effective execution of the milling process.

[0045] Therefore, a first mounting base 1, a second mounting base 2, and a connecting base 3 were designed. These components can be designed as a single piece to simplify the structure, or they can be designed as separate, detachable parts to enhance maintenance convenience and flexibility.

[0046] The first mounting base 1 is designed with a first material chamber 101, which is mainly used to receive wheat raw materials to be processed. In order to maximize the use of space and optimize the material flow path, the first material chamber 101 is set in a cylindrical shape and its axis is arranged horizontally. This layout helps to reduce the overall height requirement of the equipment while maintaining good material transfer efficiency. Wheat enters the first material chamber 101 through the first inlet 102 located at the top. The second mounting base 2 includes a second material chamber 201, which also adopts a cylindrical design and a horizontal axis. It is connected to the first material chamber 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 blower 4 is used to perform air separation, effectively separating impurities (such as stones) that are similar in size but have a higher density, causing them to fall into the impurity outlet 302, while the wheat particles enter the second material chamber 201. The connecting seat 3 ensures a stable connection between the first mounting seat 1 and the second mounting seat 2. Whether using an integrated or modular design, it's crucial to ensure excellent system sealing and seamless integration between components to facilitate a continuous workflow. Through this innovative design approach—utilizing horizontal spatial expansion instead of traditional vertical stacking—this solution successfully reduces the overall height requirement of the wheat mill, significantly improving its flexibility for placement in laboratories. Furthermore, precise control of airflow effectively removes foreign matter from the wheat, ensuring the purity of the final product and laying a solid foundation for subsequent processing steps. This compact screening device is not only suitable for small-scale experimental environments in research institutions but also offers insights for small-scale flour production in commercial applications.

[0047] Furthermore, to further improve air separation efficiency and ensure smoother material entry into the second material chamber 201, a guide section 10 is specifically introduced in the design. This component is designed to optimize the airflow path and material flow trajectory, enabling effective separation of wheat particles and impurities under the action of airflow. The main function of the guide section 10 is to guide the airflow direction through its specific geometry and control the movement trajectory of the materials (including wheat and impurities such as stones mixed in). When the mixture passes through the guide section 10 under the airflow generated by the blower 4, particles of different masses are affected to varying degrees. The guide section 10 adopts an inclined surface 902 or a curved surface structure (a curved surface is used in this design). This design helps to form a smooth transition area, prompting the material to move along a preset path. When wheat raw material containing impurities is blown out of the first feeding chamber 101 and moves along the guide section 10, the lighter wheat particles will rise along the guide surface under the action of the wind, pass through the guide section 10, and cross the impurity outlet 302 in a parabolic trajectory, finally falling into the second feeding chamber 201 for further processing. In contrast, those foreign objects with higher density and relatively similar volume but heavier weight (such as small stones) will have a shorter parabolic path due to their greater weight, and will fall into the impurity outlet 302 below and be discharged. By reasonably setting the guide section 10, the separation accuracy in the wind separation process can be significantly improved, reducing the loss of high-quality wheat while effectively removing most of the impurities.

[0048] Furthermore, the first mounting base 1 and / or the second mounting base 2 have a mounting groove 5, which is semi-circular and has a horizontally arranged axis. It also includes a grinding roller 6, which is rotatably disposed in the mounting groove 5. The length of the grinding roller 6 is equal to or less than the length of the mounting groove 5.

[0049] In this embodiment, to further optimize space utilization and reduce the overall size of the equipment, and to balance grinding efficiency, better control of flour particle size and uniformity, and meet the diverse requirements for finished product characteristics in different experimental or production processes, mounting slots 5 specifically for mounting the grinding rollers 6 are provided on the first mounting base 1 and the second mounting base 2. The special design feature of these mounting slots 5 is that their axes are also horizontally arranged, meaning that the rotation axis of the grinding rollers 6 installed within them is also horizontal. This layout strategy greatly reduces the vertical height requirement of the entire device, making the machine more compact and suitable for space-constrained applications such as laboratories. Each set of grinding rollers 6 is precisely embedded in its respective mounting slot 5, and the length of the grinding roller 6 is equal to or less than the length of the mounting slot 5. This ensures good mechanical stability without adding extra external dimensions and saves horizontal space. Furthermore, considering ease of maintenance and potential future technological upgrades, all grinding components can be designed for easy disassembly and replacement. This not only facilitates daily cleaning and maintenance, but also allows users to flexibly adjust or replace worn parts according to actual usage, 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, the mounting groove 5 is designed with a scraper 501. The scraper 501 contacts the periphery 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.

[0050] In summary, by introducing horizontally arranged grinding rollers 6 and their matching mounting grooves 5, the goal of miniaturization of the equipment has been successfully achieved, while also taking into account the requirements of high efficiency, ease of use and maintainability.

[0051] Furthermore, the second mounting base 2 is a split structure, having a base body 203 and a cylinder body 204. The cylinder body 204 has a second material cavity 201 and is rotatably mounted on the base body 203. It also includes: a first gear 7, which is mounted on the grinding roller 6 of the second mounting base 2 and is coaxial with the grinding roller 6; and a second gear 8, which is mounted on the cylinder body 204 and is coaxial with the cylinder body 204, and is meshed with the first gear 7.

[0052] Considering the inherent adhesiveness of wheat, the fan 4 is designed to effectively prevent wheat from adhering to the first material chamber 101 or the second material chamber 201. Furthermore, since the fan 4 is located in the first material chamber 101, which is relatively far from the second material chamber 201, and a guide section 10 exists between the first and second material chambers 101, which partially blocks the airflow, a special design is implemented to further prevent wheat from accumulating in the second material chamber 201.

[0053] 1. The second mounting base 2 is a split structure, comprising a base 203 and a cylinder 204. The base 203 and cylinder 204 are separately configured. The cylinder 204 contains a second material chamber 201, and the cylinder 204 can rotate on the base 203. The axis of rotation is parallel to the axis of the first material chamber 101, so that when wheat material enters the second material chamber 201, the wheat grains will roll within the chamber due to the rotation of the cylinder 204. This rolling motion helps the material to be exposed to the airflow more evenly, promoting the effective separation of impurities from the wheat. At the same time, because the material is in motion, the possibility of it adhering to the wall of the material chamber is reduced.

[0054] To achieve the rotation of the cylinder 204, the rotation of the grinding roller 6 is utilized, reducing the use of drive devices such as motors, saving space, reducing overall weight, saving costs, and reducing maintenance difficulty. 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, and the first gear 7 in turn drives the second gear 8 to rotate. The rotation of the second gear 8 enables the cylinder 204 to follow the rotation.

[0055] 2. The cross-section of the second material chamber 201 parallel to its length direction is a frustum shape, with the diameter at the end near the connecting seat 3 being smaller than the diameter at the end away from the connecting seat 3. This design allows the wheat material entering the second material chamber 201 to roll forward along the gradually increasing space, increasing the material's momentum towards the discharge port. As the space increases, the airflow space also increases, which helps to distribute the airflow more evenly on the material surface, improving air separation efficiency. The frustum shape reduces dead zones that may occur in traditional rectangular or circular material chambers, lowering the risk of material accumulation. The rotatable cylinder 204 and the frustum-shaped material chamber enhance the flowability of the material within the second material chamber 201, thus improving the overall system performance.

[0056] Furthermore, the grinding disc 9 is movable. After the grinding disc 9 moves, the grinding surface 901 rolls against the grinding roller 6 or cancels the rolling contact. The feeding disc 11 is rotatable and has a second inlet 1101 and a second outlet 1102. The first mounting base 1 and the second mounting base 2 are both disposed on the feeding disc 11 and located below the feeding disc 11. The second outlet 1102 is connected to the first inlet 102.

[0057] In this embodiment, a special design was made to ensure that the wheat material from the first discharge port 202 can be more smoothly distributed onto the grinding surface 901:

[0058] 1. The feeding tray 11 is designed to rotate around its axis. When the feeding tray 11 rotates, it drives the first mounting base 1 and the second mounting base 2 to rotate together. This linkage mechanism ensures that the two grinding rollers 6 and the first discharge port 202 move together with the feeding tray 11. Since the first discharge port 202 also moves with the rotation of the feeding tray 11, it can evenly distribute material along the circumferential boundary of the grinding plane 901. This avoids material accumulation in a certain area, thus ensuring uniform material distribution during the grinding process. When the two grinding rollers 6 rotate with the mounting bases, they can push or directly perform preliminary grinding on the grinding plane 901. This dynamic operation helps improve processing efficiency and further promotes uniform material distribution.

[0059] 2. During the wheat screening stage, the grinding disc 9 can be moved away from the grinding roller 6 via a mechanical device, creating a larger space. This allows the material discharged from the wheat outlet to enter the grinding surface 901 more easily and without obstruction. Once a large amount of wheat material accumulates in the peripheral area of ​​the grinding surface 901, the grinding disc 9 can be moved closer to the grinding roller 6. In this way, the rotation of the grinding roller 6 can effectively push this material towards the center, achieving a more uniform distribution. When the wheat material has been distributed relatively evenly, the grinding disc 9 can be moved even 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 for efficient grinding operation.

[0060] 3. The grinding disc 9 has an inclined surface 902 around 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 center of the grinding plane 901. This design helps the material reach the core area that needs to be processed more quickly. The design of the inclined surface 902 also helps to provide some shielding during the grinding process, preventing the wheat material from being moved off the grinding plane 901 due to the thrust of the grinding roller 6. At the same time, the inclined surface 902 also helps the material to naturally gather inward during the rolling process and remain within the grinding area.

[0061] Furthermore, the screen 12 is detachably mounted on the feed plate 11 and located above the feed plate 11, and the screen 12 has screen holes.

[0062] In this embodiment, the screen disc 12 is designed to be easily detached from the feed disc 11. This design facilitates regular cleaning of impurities and allows for the replacement of screens with different aperture sizes according to different material characteristics. The screen disc 12 is mounted on the feed disc 11 and rotates together with the feed disc 11. This synchronized motion helps to evenly distribute the material and improves the screening effect. The aperture of the screen is slightly larger than the average particle size of wheat, which effectively blocks longer or larger impurities (such as straw, weeds, etc.) from the screen, leaving them on the screen, while wheat grains can pass through the screen and enter the subsequent processing stage. As the screen disc 12 rotates, the material is more evenly distributed on the screen under the action of centrifugal force. This not only speeds up the screening process but also ensures that the material is screened more comprehensively. The detachable screen disc 12 design makes cleaning simple and quick; the screen disc 12 can be easily removed and impurities cleared without complicated maintenance steps, simplifying daily operations. By introducing a detachable screen plate 12 and combining it with the rotation mechanism of the feed plate 11, this design not only achieves efficient material screening, but also enhances the system's flexibility and ease of maintenance.

[0063] Furthermore, the grinding disc 9 is detachable, and after being moved, it abuts against or is below the outer wall of the grinding roller 6, thus facilitating the collection of wheat flour after grinding.

[0064] Furthermore, it also includes: a machine body 13, in which all the above-mentioned components are installed, the machine body 13 having a feed port 1301 facing the screen plate 12; and a collection trough 14, which is detachably disposed in the machine body 13 and located below the waste discharge channel 302.

[0065] In this embodiment, the collection trough 14 is installed below the waste outlet 302 to collect impurities of similar volume to wheat separated from the waste outlet 302. The collection trough 14 is detachable, facilitating regular cleaning of impurities by the user. This design not only simplifies maintenance but also ensures long-term stable operation of the equipment. Preferably, both the interior and exterior of the machine body 13 are wrapped with high-efficiency sound-insulating materials. For example, sound-absorbing cotton or sound-insulating foam can be laid on the inside of the outer shell to effectively absorb and isolate the noise generated during equipment operation. The feeding port 1301 is located at the top of the first material chamber 101 and is of moderate size, which facilitates manual addition of materials by the user while preventing dust from overflowing due to an excessively large opening. Preferably, an observation window can be opened on the side wall of the machine body 13 to observe the grinding progress inside the machine body 13, and a pull-out door 15 can be designed so that the internal devices can be disassembled and replaced after the door 15 is opened. A dust cover that can be opened and closed can also be provided, which can be closed when no material is being added to prevent dust from entering the interior of the machine body 13. All components, including the grinding roller 6, screen plate 12, feeding plate 11, rotating device of cylinder 204, and collecting tank 14, are rationally integrated into a compact and efficient machine body 13, forming a complete material handling system.
