Description

Technical Field

[0001] This application relates to the field of electrical equipment technology, and in particular to grain processing apparatus, control systems and control methods. Background Technology

[0002] A rice milling machine is a grain processing device used to dehull paddy rice and process it into fresh rice. It mainly achieves functions such as dehulling, whitening, and removing bran through mechanical grinding and friction. It is widely used in households, grain processing workshops, and large-scale rice mills.

[0003] Because the rice milling hopper is a relatively enclosed space, the temperature inside rises during the milling process. This causes the moisture in the grains to evaporate and accumulate inside, increasing the humidity and affecting the processing and preservation of the grains. To address this, most household rice milling machines are equipped with a forced convection hot air drying system. However, once this drying system is installed, its airflow structure cannot be adjusted according to product development needs, resulting in poor adaptability. This severely restricts the rapid iteration of product models and significantly increases product development costs. Summary of the Invention

[0004] Therefore, it is necessary to provide a grain processing device, control system, and control method to address the problem that the drying system of grain processing equipment has poor adaptability, cannot meet product development needs, and affects product cost control.

[0005] A grain processing apparatus, comprising:

[0006] case;

[0007] The first compartment is disposed within the shell and is used to store grains to be processed;

[0008] A second compartment is disposed within the housing and is located below the first compartment. The grain to be processed in the first compartment can be controllably moved into the second compartment, which is used to contain and transport the grain to be processed.

[0009] A drying mechanism is disposed within the housing. The drying mechanism is used to controllably dry at least a portion of the area within the housing. The drying mechanism includes a pneumatic component and at least two mounting positions, with at least one of the mounting positions housing the pneumatic component.

[0010] The aforementioned grain processing device includes a shell, a first chamber, a second chamber, and a drying mechanism. The drying mechanism includes aerodynamic components and at least two mounting positions. During product development, the aerodynamic components can be installed at at least one mounting position based on adjustments to the product's appearance design, internal module layout, or functional integration. This allows for flexible adaptation to the overall spatial layout of different product models, creating a modular and reconfigurable airflow system. This design breaks the limitations of existing fixed airflow systems on machine size and internal structure, significantly improving the flexibility and multi-scenario adaptability of the overall system layout. It meets the needs of various machine model system layouts and strongly supports product platform and serialization development. While ensuring drying and dehumidification performance, significant energy-saving effects are achieved by pre-optimizing the airflow path and reducing energy loss. Simultaneously, it reduces repeated mold opening, significantly shortens the development cycle, lowers R&D and manufacturing costs, and enhances the competitiveness and iteration efficiency of the product series.

[0011] In one embodiment of this application, each of the mounting positions corresponds to at least one air duct path, and at least two air duct paths have partially overlapping sections.

[0012] The above-mentioned grain processing device has different installation positions, so each installation position corresponds to at least one air duct path to achieve drying and dehumidification of each area inside the shell. At least two air duct paths overlap in some sections to focus on drying certain areas inside the shell, thereby achieving the optimal design of the air duct path, improving the drying and dehumidification effect, achieving outstanding energy-saving effect, and ensuring the grain processing effect and grain preservation.

[0013] In one embodiment of this application, the first chamber has a storage chamber and an installation chamber that are separated from each other. The top of the storage chamber has an exhaust vent, and the bottom of the storage chamber has a first discharge port. The first discharge port is controllably connected to the interior of the second chamber. The installation position includes a first installation position, which is located at the bottom of the installation chamber. The installation chamber is controllably connected to the second chamber through the first installation position.

[0014] The aforementioned grain processing device includes a first mounting position. Since the mounting cavity has ample space, placing the first mounting position within it improves space utilization and avoids occupying space in the lower part of the casing, facilitating the layout of other modules. Furthermore, because the first chamber is located at the top of the casing, placing the first mounting position within the mounting cavity allows for a longer air duct path, expanding the drying area and improving drying and dehumidification effects.

[0015] In one embodiment of this application, the air duct path corresponding to the first mounting position includes a first air duct path that enters the second chamber from the bottom of the mounting cavity and enters the first chamber from the first discharge port.

[0016] In the aforementioned grain processing device, when the grain is being milled, the temperature rises, and the moisture contained in the grain easily evaporates and accumulates in the second chamber. The air duct path corresponding to the first installation position can sequentially dry and dehumidify the second chamber and the first chamber, achieving a targeted drying process and improving the drying and dehumidification effect.

[0017] In one embodiment of this application, a grain processing mechanism is disposed below the second hopper, and the bottom of the second hopper has a second discharge port. The second hopper is connected to the grain processing mechanism through the second discharge port, and the bottom of the grain processing mechanism has a third discharge port. The grain processing device further includes a first storage box, which is disposed below the grain processing mechanism. After processing by the grain processing mechanism, the grain can be controllably fed into the first storage box from the third discharge port. The air duct path corresponding to the first mounting position includes a second air duct path that enters the second hopper from the bottom of the first hopper, enters the grain processing mechanism from the second discharge port, and then enters the first storage box from the third discharge port.

[0018] The aforementioned grain processing device, with the air duct path corresponding to the first installation position, can also dry and dehumidify the first storage box. The first storage box is used to store processed grains, such as rice, thereby achieving preservation of processed grains, preventing grains from getting damp and moldy, and improving food safety.

[0019] In one embodiment of this application, the mounting position includes a second mounting position disposed on the top of the first storage box, and the grain processing mechanism is controllably connected to the first storage box through the second mounting position.

[0020] The aforementioned grain processing apparatus includes a second mounting position, which is located on top of the first storage box. When the aerodynamic component is located in the second mounting position, it can enhance the drying effect on the first storage box and improve the freshness of the processed grain.

[0021] In one embodiment of this application, the air duct path corresponding to the second installation position includes a fourth air duct path that enters the first storage box from the top of the first storage box, enters the grain processing mechanism from the third discharge port, then enters the second chamber from the second discharge port, and then enters the first chamber from the first discharge port.

[0022] The aforementioned grain processing device, with the air duct path corresponding to the second installation position, can sequentially dry and dehumidify the first storage box, a portion of the grain processing mechanism, the second chamber, and the first chamber. The drying treatment has a wide coverage area, reduces drying dead zones, and can achieve uniform drying of the internal area of ​​the shell. The processing efficiency is high and the effect is stable and reliable, greatly improving the quality of the processed grain.

[0023] In one embodiment of this application, a second storage box is further included, which is disposed below the grain processing mechanism. The bottom of the grain processing mechanism has a fourth discharge port, and the husks generated during the processing of the grain processing mechanism enter the second storage box from the fourth discharge port. The air duct path corresponding to the first mounting position includes a third air duct path that enters the second chamber from the bottom of the first chamber, enters the grain processing mechanism from the second discharge port, and then enters the second storage box from the fourth discharge port.

[0024] The air duct path corresponding to the first installation position of the above-mentioned grain processing device can also dry and dehumidify the second storage box. The second storage box is used for the husks produced during the grain processing process. It can reduce the humidity inside the second storage box, reduce the stickiness of the husks, make the husks inside the second storage box easy to clean, and facilitate user operation.

[0025] In one embodiment of this application, the grain processing mechanism includes a processing shaft and a screen, the screen being sleeved outside the processing shaft, and a fitting gap between the processing shaft and the screen suitable for grain passage; the third air duct path includes a section extending from the second discharge port along the fitting gap to the fourth discharge port and entering the second storage box.

[0026] In the aforementioned grain processing device, during grain processing, the grain enters the gap between the processing shaft and the screen. Through mechanical grinding and friction, the grain is dehulled, whitened, and chaff removed. Therefore, the humidity in this gap is relatively high, making it easy for grain and chaff to stick and accumulate. The third air duct path also includes the gap section between the processing shaft and the screen, which can perform drying treatment on this gap, reducing the humidity and causing the sticky grain and chaff to fall off, facilitating subsequent grain processing and ensuring the best processing results.

[0027] In one embodiment of this application, the mounting position includes a third mounting position disposed on the top of the second storage box, and the grain processing mechanism is controllably connected to the second storage box through the third mounting position.

[0028] The above-mentioned grain processing device includes a third mounting position, which is located on top of the second storage box. When the aerodynamic component is located in the third mounting position, it can enhance the drying effect on the second storage box, keeping the grain husks inside the second storage box dry and easy to clean.

[0029] In one embodiment of this application, when the second discharge port is opened, the air duct path corresponding to the third installation position includes a fifth air duct path that enters the second storage box from the top of the second storage box, enters the grain processing mechanism from the fourth discharge port, then enters the second chamber from the second discharge port, and then enters the first chamber from the first discharge port.

[0030] When the second discharge port of the above-mentioned grain processing device is opened, the air duct path corresponding to the third installation position can sequentially dry and dehumidify the second storage box, a part of the grain processing mechanism, the second chamber and the first chamber. The drying treatment has a wide coverage area, reduces drying dead corners, and can achieve uniform drying of the internal area of ​​the shell. The processing efficiency is high and the effect is stable and reliable, making the husk easier to clean and providing convenience for users.

[0031] In one embodiment of this application, the fifth air duct path includes a section extending from the fourth discharge port along the fitting gap to the second discharge port and into the second hopper.

[0032] The aforementioned grain processing device also includes a fifth air duct path that includes a gap section between the processing shaft and the screen. This gap can be dried to reduce the humidity, causing the sticky grains and husks to fall off, facilitating further processing and ensuring the grain processing effect.

[0033] In one embodiment of this application, when the second discharge port is closed, the air duct path corresponding to the third installation position includes a sixth air duct path that enters the second storage box from the top of the second storage box, enters the grain processing mechanism from the fourth discharge port, and then enters the first storage box from the third discharge port.

[0034] When the second discharge port of the above-mentioned grain processing device is closed, the air duct path corresponding to the third installation position can sequentially dry and dehumidify the second storage box, a part of the grain processing mechanism and the first storage box. This can enhance the uniform drying of grains and husks, improve the drying efficiency, significantly improve the quality of the processed grains, and make the husks easier to clean, providing convenience for users.

[0035] In one embodiment of this application, the working state of the aerodynamic component includes a blowing state and a suction state. The aerodynamic component is provided at at least two of the mounting positions. During drying, at least one of the aerodynamic components is in the blowing state and at least one of the aerodynamic components is in the suction state.

[0036] The aforementioned grain processing device uses a bidirectional fan as its aerodynamic component, which operates in both blowing and suction modes. The aerodynamic component is installed in at least two locations, allowing it to cooperate with each other. Specifically, at least one aerodynamic component is in the blowing mode, and at least one aerodynamic component is in the suction mode, thereby enhancing the drying and dehumidification effects. At the same time, it can reduce the rotational speed of individual aerodynamic components, reduce overall machine noise and energy consumption, and extend the service life of the aerodynamic components.

[0037] In one embodiment of this application, the mounting position where the aerodynamic component is not provided is sealed by a cover component.

[0038] The aforementioned grain processing device has a sealing component installed at the installation position where no aerodynamic components are installed to block the installation position, which can reduce the disturbance of the drying airflow and avoid affecting the grain processing or the storage of grains and husks.

[0039] In one embodiment of this application, a humidity detection device is further included, which is disposed in the second chamber and is used to detect the humidity in the second chamber.

[0040] The aforementioned grain processing device can obtain the air humidity value inside the second chamber by setting a humidity detection device, thereby adjusting the drying and dehumidification process according to the actual air humidity, and realizing the drying feedback regulation of the grain processing device.

[0041] In one embodiment of this application, a positioning detection mechanism is further included. The positioning detection mechanism is disposed at the mounting position and is used to detect whether the aerodynamic component is provided at the mounting position.

[0042] The aforementioned grain processing device, by setting up a positioning detection mechanism, can determine which installation position has a pneumatic component, so as to facilitate the drying process control of the grain processing device and improve the overall intelligence and automation level of the machine.

[0043] In one embodiment of this application, an interactive interface is also included, which is disposed on the outer wall of the housing, and the interactive interface is used for the user to input the installation position information of the aerodynamic component.

[0044] In the aforementioned grain processing device, users can select and input the installation location information of the aerodynamic components through an interactive interface, so as to facilitate the drying process control of the grain processing device and improve the overall intelligence and automation level of the machine.

[0045] In one embodiment of this application, the aerodynamic component includes a heating module for heating the airflow passing through the aerodynamic component.

[0046] The aforementioned grain processing apparatus includes a heating module in its aerodynamic components to heat the drying airflow, increase the temperature of the drying airflow, achieve high-temperature rapid drying, accelerate the drying process, and improve the drying and dehumidification effects.

[0047] In one embodiment of this application, the grain processing apparatus is a rice milling machine.

[0048] The aforementioned grain processing device is specifically a rice milling machine, used to process grains for convenient household or commercial use.

[0049] A control system is applied to the above-mentioned grain processing device. The control system includes a main control module, the signal input terminal of which is electrically connected to the interactive interface and / or the positioning detection mechanism, and the signal output terminal of which is electrically connected to the aerodynamic component.

[0050] The aforementioned control system, when applied to the aforementioned grain processing apparatus, has the same beneficial effects as the grain processing apparatus, which will not be elaborated here.

[0051] In one embodiment of this application, the signal input terminal of the main control module is also electrically connected to the humidity detection device.

[0052] The aforementioned control system can obtain the actual air humidity inside the grain processing device based on the detection results of the humidity detector, and then adjust the drying and dehumidification processes to achieve feedback regulation of the drying process and improve the accuracy of drying and dehumidification control.

[0053] In one embodiment of this application, the main control module has a pre-installed control program, which includes a first control subroutine matched to each mounting position where the aerodynamic component is individually installed, and a second control subroutine matched to at least two mounting positions where the aerodynamic component is installed.

[0054] The aforementioned control system has a pre-set control program, which includes a first control subroutine and a second control subroutine. The first control subroutine is designed for cases where aerodynamic components are installed individually at each mounting position, while the second control subroutine is designed for cases where aerodynamic components are installed at at least two mounting positions. This enhances the flexibility of the overall system layout and its adaptability to various scenarios, meeting the control needs of system layouts for multiple models.

[0055] In one embodiment of this application, each of the first control subroutines corresponds to an operating mode of the aerodynamic component, the operating mode including a first operating mode, a second operating mode and a third operating mode, the first operating mode matching the case where the aerodynamic component is provided at a first mounting position, the second operating mode matching the case where the aerodynamic component is provided at a second mounting position, and the third operating mode matching the case where the aerodynamic component is provided at a third mounting position.

[0056] The control system described above has a first control subroutine corresponding to an operating mode of an aerodynamic component. The operating modes include a first operating mode, a second operating mode, and a third operating mode. Each operating mode corresponds to different installation positions of the aerodynamic component, so as to facilitate drying and dehumidification control, improve the flexibility of the overall system layout and adaptability to multiple scenarios, and meet the control needs of various machine model system layouts.

[0057] A control method, executed by the aforementioned control system, the control method comprising:

[0058] Obtain the installation location information of aerodynamic components;

[0059] The corresponding control program is executed based on the installation location information to control the operation of the aerodynamic components.

[0060] The above control method is executed by the above control system and has the same beneficial effects as the control system, which will not be elaborated here.

[0061] In one embodiment of this application, the step of obtaining the installation position information of the aerodynamic component includes: obtaining the installation position information by obtaining user input signals from an interactive interface, or obtaining the installation position information by obtaining detection signals from a positioning detection mechanism.

[0062] The above control method involves two steps to obtain the installation position information of aerodynamic components: user input and position detection. This makes the system control highly flexible, meets the design needs of different models, and improves product adaptability.

[0063] In one embodiment of this application, after the step of executing the corresponding control program according to the installation location information to control the operation of the aerodynamic component, the method further includes: obtaining the humidity detection result of the humidity detection device, and adjusting the airflow of the aerodynamic component according to the humidity detection result.

[0064] The above control method, by detecting the air humidity value, can adjust the drying process according to the actual air humidity inside the machine, realize humidity feedback regulation, and improve the reliability of drying control. Attached Figure Description

[0088] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0089] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0090] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0091] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0092] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0093] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0094] See Figures 1-10As shown, an embodiment of this application provides a grain processing apparatus, comprising: a shell 1, a first chamber 2, a second chamber 3, and a drying mechanism. The first chamber 2 is disposed within the shell 1 and is used to store grains to be processed. The second chamber 3 is disposed within the shell 1 and is located below the first chamber 2. The grains to be processed in the first chamber 2 can be controllably introduced into the second chamber 3, which is used to contain and transport the grains to be processed. The drying mechanism is disposed within the shell 1 and is used to controllably dry at least a portion of the area within the shell 1. The drying mechanism includes an aerodynamic component 4 and at least two mounting positions 5, with at least one mounting position 5 housing the aerodynamic component 4.

[0095] This grain processing device, during product development, can utilize at least one mounting position 5 to house the aerodynamic component 4, adapting to the overall spatial layout of different product models, based on adjustments to product appearance design, internal module arrangement, or functional integration. This allows for flexible adaptation to different product models, creating a modular and reconfigurable airflow system. This design breaks the limitations of existing fixed airflow systems on machine size and internal structure, significantly improving the flexibility and multi-scenario adaptability of the overall system layout. It meets the needs of various machine model system layouts, strongly supporting the platformization and serialization of product development. While ensuring drying and dehumidification performance, significant energy-saving effects are achieved by pre-optimizing the airflow path and reducing energy loss. This reduces redundant mold opening, significantly shortens the development cycle, lowers R&D and manufacturing costs, and enhances the competitiveness and iteration efficiency of the product series.

[0096] The grain processing device of this application is used to process grains. For example, the grain processing device can be a rice milling machine, or optionally, a household rice milling machine, used to dehull paddy rice and process it into fresh rice such as brown rice, germ-rich rice, and polished white rice. This rice milling machine has functions such as dehulling, grinding, and rice discharge, and features low noise, compatibility with multiple rice varieties, and fully automatic quantitative feeding.

[0097] The grain processing device includes a shell 1, which is the main structure of the grain processing device. The shell 1 has sufficient structural strength to support and house other structural components of the grain processing device. (See also...) Figure 1 As shown, in one embodiment, the housing 1 of the grain processing device is generally a cuboid structure. This grain processing device has a regular and compact appearance, occupies little space, and is easy to install.

[0098] See Figures 2-3As shown, the shell 1 has an internal cavity containing a first compartment 2 and a second compartment 3. The first compartment 2 (or rice silo) is located at the top of the cavity and is used to store grains, such as rice, to be processed. The first compartment 2 has sufficient structural strength to support other internal structural components and accommodate the grains to be processed.

[0099] The second compartment 3 (or circulation compartment) is located within the housing cavity and below the first compartment 2. The grain to be processed in the first compartment 2 can be controlled to enter the second compartment 3, which is used to contain and transport the grain. During grain processing, the second compartment 3 forms part of the grain circulation path, and its specific volume can be selected and set according to the grain processing requirements.

[0100] The shell 1 is also equipped with a drying mechanism, which is used to controllably dry at least a portion of the area inside the shell 1 to reduce the internal humidity of the shell 1 and improve the grain processing effect and grain freshness. Depending on the design requirements of different products, the drying mechanism can dry only a portion of the area inside the shell 1. For example, the drying mechanism can target areas with higher humidity inside the shell 1 to improve drying efficiency and save energy; or, the drying mechanism can dry the entire area inside the shell 1 to achieve comprehensive dehumidification and better drying and dehumidification effects.

[0101] The drying mechanism includes an aerodynamic component 4 and at least two mounting positions 5, wherein the aerodynamic component 4 is used to blow out or draw humid air from inside the housing 1. In one embodiment, the aerodynamic component 4 is a fan, for example, a high-efficiency fan with a rated power of 30W to 80W.

[0102] Mounting position 5 refers to the mounting position of the aerodynamic component 4. There are at least two mounting positions 5 within the housing 1; for example, there can be two, three, four, or five mounting positions 5, each capable of mounting one aerodynamic component 4. Understandably, the positions of each mounting position 5 are different; therefore, installing the aerodynamic component 4 at one or more mounting positions 5 in different locations will create different drying airflow paths to meet the drying needs of different products. Furthermore, since the positions of each mounting position 5 are pre-set, the grain processing apparatus of this application pre-optimizes the airflow paths of each mounting position 5, effectively reducing energy loss and achieving significant energy-saving effects.

[0103] Depending on the design requirements of different products, at least one mounting position 5 in the same product may be equipped with an aerodynamic component 4. For example, in the same product, one, two, three, or five mounting positions 5 may be equipped with an aerodynamic component 4, while mounting positions 5 without an aerodynamic component 4 are considered unoccupied. In different products, the aerodynamic component 4 may be installed in mounting positions 5 at different locations to meet the design requirements of different product models. Furthermore, when multiple mounting positions 5 are equipped with aerodynamic components 4, the aerodynamic components 4 work together to achieve the drying and dehumidification process in different areas within the housing 1.

[0104] In one embodiment, the mounting position 5 is a mounting interface, the inner diameter of which matches the outer diameter of the aerodynamic component 4. The aerodynamic component 4 can be inserted into and mounted on this mounting interface. The aerodynamic component 4 can be mounted on the mounting position 5 using universal screws or quick-connect clips. Furthermore, the dimensions of the aerodynamic component 4 and each mounting position 5 are standardized to allow the aerodynamic component 4 to be matched and installed on mounting positions 5 at different locations, meeting the design requirements of different product models.

[0105] In one embodiment, mounting position 5 is a mounting interface, and a sealing ring, such as an O-ring silicone seal, is embedded in the inner wall of the mounting interface. When the aerodynamic component 4 is installed in mounting position 5, the sealing ring is compressed and deformed, thereby ensuring a good seal at the connection between the aerodynamic component 4 and mounting position 5. In one embodiment, the air leakage rate at the connection between the aerodynamic component 4 and mounting position 5 is less than 3%. The above design allows users or production lines to replace and connect the aerodynamic component 4 and mounting position 5 without using tools, greatly improving assembly efficiency and maintenance convenience.

[0106] In one embodiment, a vent 102 is provided on the side wall of the housing 1. The vent 102 is used to realize the airflow interaction between the inside of the housing 1 and the outside atmosphere, and to assist in the drying and dehumidification process.

[0107] In one embodiment, a display screen 12 is also provided on the outer wall of the housing 1 for user interaction.

[0108] In one embodiment of this application, each mounting position 5 corresponds to at least one air duct path, and at least two air duct paths have partially overlapping sections.

[0109] Within the housing 1, due to the different locations of the mounting positions 5, when a pneumatic component 4 is installed on each mounting position 5, each mounting position 5 corresponds to at least one air duct path, thereby achieving drying treatment of different areas within the housing 1. This makes the product design more targeted and meets the design needs of different product models. The air duct path refers to the path that the drying airflow follows when the pneumatic component 4 is running.

[0110] Depending on the internal structure design of different products, each installation position 5 can correspond to one, two, three or more air duct paths. In order to meet the design needs of different products and make the drying air duct paths more diverse, at least two air duct paths have overlapping sections.

[0111] At least two air duct paths overlap in certain sections, including:

[0112] For the same mounting position 5, when the mounting position 5 corresponds to at least two air duct paths, some sections of the at least two air duct paths corresponding to the mounting position 5 overlap.

[0113] For different installation positions 5, each installation position 5 corresponds to at least one air duct path, and at least two of these air duct paths have partially overlapping sections.

[0114] For example, a certain mounting position 5 corresponds to three air duct paths, and two or three of these air duct paths have overlapping sections. Alternatively, there may be four mounting positions 5, each corresponding to one air duct path, resulting in a total of four air duct paths. In this case, two or three of these air duct paths have overlapping sections. This allows for focused drying of specific areas within the housing 1, improving drying and dehumidification effects and ensuring optimal grain processing and preservation. Furthermore, this configuration optimizes the air duct path design, enhancing drying and dehumidification, resulting in significant energy savings, and ensuring optimal grain processing and preservation.

[0115] In one embodiment of this application, the first chamber 2 has a storage chamber 201 and an installation chamber 202 that are separated from each other. The top of the storage chamber 201 has an exhaust port and the bottom of the storage chamber 201 has a first discharge port 2011. The first discharge port 2011 is controllably connected to the interior of the second chamber 3. The installation position 5 includes a first installation position 501, which is disposed at the bottom of the installation chamber 202. The installation chamber 202 is controllably connected to the second chamber 3 through the first installation position 501.

[0116] See Figures 2-3As shown, the first silo 2 has a storage cavity 201 and an installation cavity 202, which are separated from each other and do not communicate with or affect each other. The storage cavity 201 is used to store grains to be processed, such as rice. After entering the storage cavity 201, the grains are temporarily stored there for subsequent processing such as hulling. The specific capacity of the storage cavity 201 can be determined based on the dimensions of the first silo 2 and other related structural layouts. The installation cavity 202 is used to house other structures of the first silo 2, and its specific capacity can be determined based on the dimensions of the first silo 2 and other related structural layouts.

[0117] The storage chamber 201 has a feed inlet at the top, through which the user can add grains to be processed. The bottom of the storage chamber 201 has a first discharge outlet 2011, which is controllably connected to the interior of the second chamber 3. An opening and closing mechanism is provided at the bottom of the storage chamber 201 to control the opening and closing of the first discharge outlet 2011. When the first discharge outlet 2011 is open, the grains to be processed in the storage chamber 201 can fall from the first discharge outlet 2011 into the second chamber 3 under gravity, thereby increasing the discharge rate and reducing the risk of blockage at the first discharge outlet 2011. Furthermore, the feed inlet and the first discharge outlet 2011 are arranged vertically relative to each other, making the structural layout of the first chamber 2 more rational and increasing the utilization rate of the internal space of the first chamber 2.

[0118] In one embodiment, at least a portion of the cross-section of the storage cavity 201 gradually narrows from the inlet to the first outlet 2011. The cross-section refers to the section of the storage cavity 201 perpendicular to the discharge direction; that is, from the inlet to the first outlet 2011, at least a portion of the storage cavity 201 has a constricted structure, which facilitates a more even and smooth downward movement of the grains to be processed within the storage cavity 201. The discharge direction is vertically downward. Specifically, the top of the inner wall of the storage cavity 201 is connected to the inlet, and the bottom is connected to the first outlet 2011. Because the area of ​​the inlet is larger than the area of ​​the first outlet 2011, the inner wall of the storage cavity 201 has a funnel-shaped structure (i.e., a constricted structure) that is larger at the top and smaller at the bottom. This structure of the storage cavity 201 facilitates a faster and smoother fall of the grains along the inner wall of the storage cavity 201, further improving the discharge rate of the first chamber 2.

[0119] In one embodiment, a top plate 101 is detachably provided on the top of the housing 1. When it is not necessary to add grains to be processed into the storage chamber 201, the top plate 101 can cover the inlet to close the storage chamber 201 and prevent foreign matter from entering the storage chamber 201.

[0120] In one embodiment, to accelerate the circulation and discharge of the drying airflow within the housing 1, an exhaust vent is provided at the top of the storage chamber 201. The exhaust vent can be configured in various ways. For example, the inlet itself can serve as the exhaust vent. In this case, when drying and dehumidifying the housing 1 are required, the top plate 101 is removed, the inlet is opened, and the inlet acts as the exhaust vent, allowing the humid air inside the housing 1 to be discharged. Alternatively, an exhaust vent can be formed on the top plate 101. In this case, the area of ​​the exhaust vent is smaller than the area of ​​the top plate 101. When drying and dehumidifying the housing 1 are required, the top plate 101 does not need to be removed to discharge the humid air inside the housing 1. Furthermore, a perforated grille can be provided at the exhaust vent, serving to prevent dust and ensure even airflow.

[0121] See Figure 2 As shown, the mounting position 5 includes a first mounting position 501, which is located at the bottom of the mounting cavity 202 to improve the utilization of the mounting space. The mounting cavity 202 is controllably connected to the second chamber 3 through the first mounting position 501. Specifically, when the first mounting position 501 is equipped with an aerodynamic component 4, the mounting cavity 202 is connected to the second chamber 3 through the first mounting position 501. When the aerodynamic component 4 is working, air circulates between the mounting cavity 202 and the second chamber 3 to achieve the drying and dehumidification process. When the first mounting position 501 is not equipped with an aerodynamic component 4, the first mounting position 501 is an empty mounting position. In this case, to avoid the empty mounting position affecting the operation of the aerodynamic components 4 on other mounting positions 5, a sealing component (such as a cover plate) can be used to seal the first mounting position 501. In this case, the mounting cavity 202 will not be connected to the second chamber 3 through the first mounting position 501.

[0122] In one embodiment of this application, the air duct path corresponding to the first mounting position 501 includes a first air duct path 601 that enters the second chamber 3 from the bottom of the mounting cavity 202 and enters the first chamber 2 from the first discharge port 2011.

[0123] See Figure 6 As shown, the air duct path corresponding to the first mounting position 501 includes a first air duct path 601. The first air duct path 601 enters the second chamber 3 from the bottom of the mounting cavity 202 and enters the first chamber 2 from the first discharge port 2011. During drying, the drying airflow performs drying and dehumidification treatment along the first air duct path 601. Specifically, during drying, the first discharge port 2011 and the exhaust port are opened, and the aerodynamic component 4 blows air towards the second chamber 3 to form a drying airflow. The drying airflow enters the second chamber 3 from the bottom of the mounting cavity 202 and enters the first chamber 2 from the first discharge port 2011, and finally exits the housing 1 from the exhaust port.

[0124] When the grain is being milled, the temperature rises and the moisture in the grain easily evaporates and accumulates in the second chamber 3. The drying airflow travels along the first air duct path 601 and can dry and dehumidify the second chamber 3 and the first chamber 2 in sequence, realizing a targeted drying process and improving the drying and dehumidification effect.

[0125] In one embodiment of this application, a grain processing mechanism is provided below the second chamber 3. The bottom of the second chamber 3 has a second discharge port 301, and the second chamber 3 is connected to the grain processing mechanism through the second discharge port 301. The bottom of the grain processing mechanism has a third discharge port 701. The grain processing device also includes a first storage box 8, which is located below the grain processing mechanism. After processing, the grain can be controlled to enter the first storage box 8 from the third discharge port 701. The air duct path corresponding to the first mounting position 501 includes a second air duct path 602 that enters the second chamber 3 from the bottom of the first chamber 2, enters the grain processing mechanism from the second discharge port 301, and then enters the first storage box 8 from the third discharge port 701.

[0126] A grain processing mechanism is located below the second compartment 3. This mechanism is used to grind, dehull, and polish the grain to produce fresh rice such as unpolished rice, germ-rich rice, and polished white rice. The second compartment 3 has a second discharge port 301 at its bottom, which connects it to the grain processing mechanism. Grain inside the second compartment 3 is transported to the grain processing mechanism through this port for processing. During processing, the grain circulates between the second compartment 3 and the grain processing mechanism until processing is complete. The grain processing mechanism has a third discharge port 701 at its bottom, through which the processed grain is discharged.

[0127] The grain processing device also includes a first storage box 8, also known as a rice box, which is used to store processed grains, such as rice. The first storage box 8 is located below the grain processing mechanism, and the processed grains can be controlled to enter the first storage box 8 from the third discharge port 701. Specifically, the top of the first storage box 8 has a rice inlet, and an inlet control mechanism is provided at the inlet to control the opening and closing of the inlet. When grain processing is complete, the inlet control mechanism opens the inlet, and the processed grains are discharged from the third discharge port 701 of the grain processing mechanism and enter the rice inlet, thus being stored in the first storage box 8.

[0128] See Figure 6As shown, the air duct path corresponding to the first mounting position 501 includes a second air duct path 602. The second air duct path 602 enters the second chamber 3 from the bottom of the first chamber 2, enters the grain processing mechanism from the second discharge port 301, and then enters the first storage box 8 from the third discharge port 701. During drying, the drying airflow dries and dehumidifies along the second air duct path 602. Specifically, during drying, the rice inlet and the exhaust port are opened, and the aerodynamic component 4 blows air towards the second chamber 3 to form a drying airflow. The drying airflow enters the second chamber 3 from the bottom of the first chamber 2, enters the grain processing mechanism from the second discharge port 301, and then enters the first storage box 8 from the third discharge port 701 via the rice inlet to dry and dehumidify the grain stored in the first storage box 8.

[0129] The second air duct path 602 can sequentially dry and dehumidify parts of the second chamber 3, the grain processing mechanism, and the first storage box 8. The drying process has a wide coverage area, reduces drying dead zones, and can achieve uniform drying of the internal area of ​​the shell 1. The processing efficiency is high and the effect is stable and reliable, which greatly improves the quality of the processed grain.

[0130] In one embodiment of this application, the grain processing apparatus further includes a second storage box 9, which is disposed below the grain processing mechanism. The bottom of the grain processing mechanism has a fourth discharge port 702. The husks generated during the processing of the grain processing mechanism enter the second storage box 9 from the fourth discharge port 702. The air duct path corresponding to the first mounting position 501 includes a third air duct path 603, which enters the second chamber 3 from the bottom of the first chamber 2, enters the grain processing mechanism from the second discharge port 301, and then enters the second storage box 9 from the fourth discharge port 702.

[0131] The grain processing mechanism has a fourth discharge port 702 at its bottom, through which the husks produced during grain processing are discharged. The grain processing device also includes a second storage box 9, also called a bran box, for storing husks, such as rice bran, produced during grain processing. The second storage box 9 is located below the grain processing mechanism, and the husks produced during grain processing enter the second storage box 9 through the fourth discharge port 702. Specifically, the second storage box 9 has a bran inlet at its top, through which the husks produced during grain processing are discharged from the fourth discharge port 702 and enter the bran inlet, thus being stored in the second storage box 9. In one embodiment, both the fourth discharge port 702 and the bran inlet are normally open.

[0132] See Figure 6As shown, the air duct path corresponding to the first mounting position 501 includes a third air duct path 603. The third air duct path 603 enters the second chamber 3 from the bottom of the first chamber 2, enters the grain processing mechanism from the second discharge port 301, and then enters the second storage box 9 from the fourth discharge port 702. During drying, the drying airflow dries and dehumidifies along the third air duct path 603. Specifically, during drying, the exhaust port is opened, and the aerodynamic component 4 blows air towards the second chamber 3 to form a drying airflow. The drying airflow enters the second chamber 3 from the bottom of the first chamber 2, enters the grain processing mechanism from the second discharge port 301, and then enters the second storage box 9 from the fourth discharge port 702 to dry and dehumidify the chaff stored in the second storage box 9.

[0133] The third air duct path 603 can sequentially dry and dehumidify parts of the second chamber 3, the grain processing mechanism, and the second storage box 9. The drying process has a wide coverage area, reduces drying dead zones, and can achieve uniform drying of the internal area of ​​the shell 1. The processing efficiency is high and the effect is stable and reliable.

[0134] In one embodiment, see [reference] Figure 1 As shown, taking the view facing the display screen 12 as an example, with the display screen 12 as the front, the first mounting position 501 is located near the rear of the housing 1. When the first mounting position 501 is equipped with the aerodynamic component 4, a back-to-forehead through-drying mode is formed. This drying mode can effectively improve the drying speed of the grains in the front and prevent moisture from accumulating near the second discharge port 301 of the second chamber 3, making it suitable for compact models.

[0135] In one embodiment of this application, the mounting position 5 includes a second mounting position 502, which is disposed on the top of the first storage box 8, and the grain processing mechanism is controllably connected to the first storage box 8 through the second mounting position 502.

[0136] See Figure 3As shown, mounting position 5 includes a second mounting position 502, which is located on top of the first storage box 8. The second mounting position 502 should be offset from the rice inlet of the first storage box 8 to avoid structural interference. The grain processing mechanism is controllably connected to the first storage box 8 through the second mounting position 502. Specifically, when the second mounting position 502 is equipped with an aerodynamic component 4, the grain processing mechanism can communicate with the interior of the first storage box 8 through the second mounting position 502. When the aerodynamic component 4 is working, air circulates between the grain processing mechanism and the first storage box 8 to achieve the drying and dehumidification process. When the second mounting position 502 is not equipped with an aerodynamic component 4, it is an empty mounting position. In this case, to avoid the empty mounting position affecting the operation of the aerodynamic components 4 on other mounting positions 5, a sealing component (such as a cover plate) can be used to seal the second mounting position 502. In this case, the grain processing mechanism will not communicate with the first storage box 8 through the second mounting position 502.

[0137] In one embodiment of this application, the air duct path corresponding to the second mounting position 502 includes a fourth air duct path 604, which enters the first storage box 8 from the top of the first storage box 8, enters the grain processing mechanism from the third discharge port 701, then enters the second chamber 3 from the second discharge port 301, and then enters the first chamber 2 from the first discharge port 2011.

[0138] See Figure 7 As shown, the air duct path corresponding to the second mounting position 502 includes a fourth air duct path 604. The fourth air duct path 604 enters the first storage box 8 from the top of the first storage box 8, enters the grain processing mechanism from the third discharge port 701, then enters the second chamber 3 from the second discharge port 301, and then enters the first chamber 2 from the first discharge port 2011. During drying, the drying airflow is dried and dehumidified along the fourth air duct path 604. Specifically, during drying, the rice inlet, the first discharge port 2011, and the exhaust port are opened. The aerodynamic component 4 blows air towards the inside of the first storage box 8 to form a drying airflow. The drying airflow enters the first storage box 8 from the top of the first storage box 8, passes through the rice inlet, enters the grain processing mechanism from the third discharge port 701, then enters the second chamber 3 from the second discharge port 301, and then enters the first chamber 2 from the first discharge port 2011, finally exiting the shell 1 from the exhaust port.

[0139] The fourth air duct path 604 can sequentially dry and dehumidify the first storage box 8, a part of the grain processing mechanism, the second chamber 3, and the first chamber 2. The drying treatment has a wide coverage area, reduces drying dead corners, and can achieve uniform drying of the internal area of ​​the shell 1. The processing efficiency is high and the effect is stable and reliable, which greatly improves the quality of the processed grain.

[0140] In one embodiment, see [reference] Figure 1As shown, taking the view facing the display screen 12 as an example, with the display screen 12 as the front, the second mounting position 502 is located near the bottom of the housing 1. When the aerodynamic component 4 is installed in the second mounting position 502, a vertical drying mode from bottom to top is formed. This drying mode has sufficient heat exchange, is suitable for large-capacity models, and has high dehumidification efficiency and good drying uniformity.

[0141] In one embodiment of this application, the grain processing mechanism includes a processing shaft 10 and a screen, the screen being sleeved outside the processing shaft 10, and a fitting gap between the processing shaft 10 and the screen suitable for grain to pass through; the third air duct path 603 includes a section extending from the second discharge port 301 along the fitting gap to the fourth discharge port 702 and entering the second storage box 9.

[0142] The grain processing mechanism includes a processing shaft 10 and a screen. The screen is fitted over the processing shaft 10, and there is a suitable clearance between the processing shaft 10 and the screen for grain to pass through. Driven by a drive motor, the processing shaft 10 rotates around its axial direction and relative to the screen, causing the grain to move within the clearance. The grain within this clearance is squeezed by the processing shaft 10 and the screen, causing it to husk and thus completing the grain processing process. The screen has several holes through which the husks detach during grain processing fall. In one embodiment, the fourth discharge port 702 is a screen hole.

[0143] See Figure 6 As shown, the third air duct path 603 includes a section extending from the second discharge port 301 along the fitting gap to the fourth discharge port 702 and entering the second storage box 9. Specifically, in the third air duct path 603, after the drying airflow enters the grain processing mechanism from the second discharge port 301, it enters the fitting gap between the processing shaft 10 and the screen, travels a distance along the fitting gap, and then enters the second storage box 9 from the fourth discharge port 702 through the bran inlet.

[0144] Because the humidity is high in the gap between the processing shaft 10 and the screen, grains and husks easily stick and accumulate. The third air duct path 603 includes the gap section between the processing shaft 10 and the screen to dry the gap, reduce the humidity in the gap, and remove the sticky grains and husks, making it easier to continue processing the grains and ensuring the grain processing effect.

[0145] In one embodiment of this application, the mounting position 5 includes a third mounting position 503, which is disposed on the top of the second storage box 9, and the grain processing mechanism is controllably connected to the second storage box 9 through the third mounting position 503.

[0146] See Figure 3As shown, the mounting position 5 includes a third mounting position 503, which is located on the top of the second storage box 9. The third mounting position 503 should be offset from the inlet of the second storage box 9 to avoid structural interference. In one embodiment, the second storage box 9 has a drawer-type structure and a first storage box liner 901. The third mounting position 503 is located on top of the first storage box liner 901.

[0147] In one embodiment, the first storage box liner 901 is a metal insert injection molding structure with high structural strength. After the aerodynamic component 4 is set in the third mounting position 503 on the first storage box liner 901, it can maintain a stable position for a long time, thus improving structural reliability.

[0148] The grain processing mechanism is controllably connected to the second storage box 9 via the third mounting position 503. Specifically, when the third mounting position 503 is equipped with an aerodynamic component 4, the grain processing mechanism can communicate with the interior of the second storage box 9 through the third mounting position 503. When the aerodynamic component 4 is working, air circulates between the grain processing mechanism and the second storage box 9 to achieve the drying and dehumidification process. When the third mounting position 503 is not equipped with an aerodynamic component 4, the third mounting position 503 is an empty mounting position. In this case, to avoid the empty mounting position affecting the operation of the aerodynamic components 4 on other mounting positions 5, a sealing component (such as a cover plate) can be used to seal the third mounting position 503. In this case, the grain processing mechanism will not communicate with the second storage box 9 through the third mounting position 503.

[0149] In one embodiment of this application, when the second discharge port 301 is opened, the air duct path corresponding to the third mounting position 503 includes a fifth air duct path 605, which enters the second storage box 9 from the top of the second storage box 9, enters the grain processing mechanism from the fourth discharge port 702, then enters the second chamber 3 from the second discharge port 301, and then enters the first chamber 2 from the first discharge port 2011.

[0150] The air duct path corresponding to the third mounting position 503 is related to the open / closed state of the second discharge port 301. In one embodiment, see [reference needed]. Figure 8 As shown, when the second discharge port 301 is opened, the air duct path corresponding to the third installation position 503 includes the fifth air duct path 605. The fifth air duct path 605 enters the second storage box 9 from the top of the second storage box 9, enters the grain processing mechanism from the fourth discharge port 702, then enters the second chamber 3 from the second discharge port 301, and then enters the first chamber 2 from the first discharge port 2011.

[0151] During drying, the drying airflow is dried and dehumidified along the fifth air duct path 605. Specifically, during drying, the first discharge port 2011 and the exhaust port are opened, and the aerodynamic component 4 blows air into the second storage box 9 to form a drying airflow. The drying airflow enters the second storage box 9 from the top, passes through the bran inlet, enters the grain processing mechanism from the fourth discharge port 702, then enters the second chamber 3 from the second discharge port 301, and then enters the first chamber 2 from the first discharge port 2011, and finally exits from the exhaust port 1.

[0152] The fifth air duct path 605 can sequentially dry and dehumidify the second storage box 9, a part of the grain processing mechanism, the second chamber 3, and the first chamber 2. The drying treatment has a wide coverage area, reduces drying dead corners, and can achieve uniform drying of the internal area of ​​the shell 1. The processing efficiency is high and the effect is stable and reliable, making the husks easier to clean and providing convenience for users.

[0153] In one embodiment of this application, the fifth air duct path 605 includes a section extending from the fourth discharge port 702 along the fitting gap to the second discharge port 301 and into the second chamber 3.

[0154] See Figure 8 As shown, the fifth air duct path 605 includes a section extending from the fourth discharge port 702 along the fitting gap to the second discharge port 301 and entering the second chamber 3. Specifically, in the fifth air duct path 605, after the drying airflow enters the grain processing mechanism from the fourth discharge port 702, it enters the fitting gap between the processing shaft 10 and the screen, travels a distance along the fitting gap, and then exits from the second discharge port 301 and enters the second chamber 3.

[0155] Because the humidity is high in the gap between the processing shaft 10 and the screen, grains and husks easily stick and accumulate. The fifth air duct path 605 includes the gap section between the processing shaft 10 and the screen to dry the gap, reduce the humidity, and remove the sticky grains and husks, making it easier to continue processing the grains and ensuring the grain processing effect.

[0156] In one embodiment of this application, when the second discharge port 301 is closed, the air duct path corresponding to the third mounting position 503 includes a sixth air duct path 606 that enters the second storage box 9 from the top of the second storage box 9, enters the grain processing mechanism from the fourth discharge port 702, and then enters the first storage box 8 from the third discharge port 701.

[0157] The air duct path corresponding to the third mounting position 503 is related to the open / closed state of the second discharge port 301. In one embodiment, see [reference needed]. Figure 9As shown, when the second discharge port 301 is closed, the air duct path corresponding to the third installation position 503 includes the sixth air duct path 606. The sixth air duct path 606 enters the second storage box 9 from the top of the second storage box 9, enters the grain processing mechanism from the fourth discharge port 702, and then enters the first storage box 8 from the third discharge port 701.

[0158] During drying, the drying airflow follows the sixth air duct path 606 for drying and dehumidification. Specifically, during drying, the rice inlet is opened, and the aerodynamic component 4 blows air into the second storage box 9 to form a drying airflow. The drying airflow enters the second storage box 9 from the top, passes through the bran inlet, enters the grain processing mechanism through the fourth discharge outlet 702, and then enters the first storage box 8 through the rice inlet from the third discharge outlet 701.

[0159] The sixth air duct path 606 can sequentially dry and dehumidify the second storage box 9, a part of the grain processing mechanism, and the first storage box 8, which can enhance the uniform drying of grains and husks, improve the drying efficiency, significantly improve the quality of the processed grains, and make the husks easier to clean, providing convenience for users.

[0160] In one embodiment, see [reference] Figure 1 As shown, taking the view facing the display screen 12 as an example, with the display screen 12 at the front, the third mounting position 503 can be set close to the right or left side of the housing 1. When the aerodynamic component 4 is installed in the third mounting position 503, a horizontal drying mode is formed. This drying mode is suitable for compact models with the second storage box 9 set on the front side, effectively avoiding the formation of airflow dead zones in the grain accumulation area.

[0161] See Figures 6-9 As shown, the first air duct path 601, the second air duct path 602, the third air duct path 603, the fourth air duct path 604, and the fifth air duct path 605 overlap in the sections at the second compartment 3 and the first compartment 2. The second air duct path 602, the fourth air duct path 604, and the sixth air duct path 606 overlap in the section at the first storage box 8. The third air duct path 603, the fifth air duct path 605, and the sixth air duct path 606 overlap in the section at the second storage box 9. In the overlapping sections of the above-mentioned air duct paths, the aerodynamic component 4, when located at multiple mounting positions 5, can dry and dehumidify the overlapping sections, thereby enhancing the drying effect at the overlapping sections and achieving enhanced treatment of key areas within the shell 1, ensuring the grain processing effect, grain freshness, and ease of handling of the husks.

[0162] In one embodiment of this application, the working state of the aerodynamic component 4 includes a blowing state and a suction state. At least two mounting positions 5 are provided with the aerodynamic component 4. During drying, at least one of the aerodynamic components 4 is in the blowing state and at least one of the aerodynamic components 4 is in the suction state.

[0163] In one embodiment, the working state of the aerodynamic component 4 includes a blowing state and a suction state, that is, the aerodynamic component 4 is a bidirectional fan. This aerodynamic component 4 can both blow air and suction air. The working state of the aerodynamic component 4 can be selected according to the design of the drying mechanism to meet the design needs of different models in the product series.

[0164] In one embodiment, at least two mounting positions 5 within the housing 1 are provided with aerodynamic components 4, meaning at least two aerodynamic components 4 are provided. For example, two, three, or four mounting positions 5 may be simultaneously provided with aerodynamic components 4. In this case, at least two aerodynamic components 4 can cooperate with each other to achieve drying and dehumidification of at least a localized area within the housing 1.

[0165] Specifically, during drying, at least one of the pneumatic components 4 is in a blowing state and at least one of the pneumatic components 4 is in a suction state. For example, two mounting positions 5 are simultaneously equipped with pneumatic components 4, one of which operates in a blowing state and the other in a suction state. Alternatively, three mounting positions 5 are simultaneously equipped with pneumatic components 4, one of which operates in a blowing state, another in a suction state, and the third pneumatic component 4 can operate in either a blowing or suction state.

[0166] See Figure 10 As shown, aerodynamic components 4 are provided at the first mounting position 501, the second mounting position 502, and the third mounting position 503. In this configuration, the aerodynamic component 4 at the first mounting position 501 operates in a blowing state, the aerodynamic component 4 at the second mounting position 502 operates in a suction state, and the aerodynamic component 4 at the third mounting position 503 can operate in either a blowing or suction state. Alternatively, the aerodynamic component 4 at the first mounting position 501 operates in a blowing state, the aerodynamic component 4 at the third mounting position 503 operates in a suction state, and the aerodynamic component 4 at the second mounting position 502 can operate in either a blowing or suction state. Through the coordinated operation of multiple aerodynamic components 4, the rotational speed of a single aerodynamic component 4 can be reduced, energy consumption and noise can be decreased, and the drying rate and user experience can be improved while ensuring the drying effect.

[0167] In one embodiment of this application, the grain processing apparatus further includes a humidity detection element 11, which is disposed inside the second chamber 3 and is used to detect the humidity inside the second chamber 3.

[0168] See Figures 6-10 As shown, the grain processing device also includes a humidity detection element 11, which can be a humidity sensor. During the grain processing, since the air humidity inside the second chamber 3 is relatively high, the humidity detection element 11 is installed inside the second chamber 3. The humidity detection element 11 is used to detect the humidity inside the second chamber 3, thereby adjusting the drying and dehumidification processes according to the actual air humidity inside the second chamber 3, and realizing the drying feedback regulation of the grain processing device.

[0169] In one embodiment of this application, the grain processing apparatus further includes a positioning detection mechanism, which is disposed at the mounting position 5 and is used to detect whether the mounting position 5 is provided with an aerodynamic component 4.

[0170] The grain processing device also includes a positioning detection mechanism, which is located at the installation position 5. The positioning detection mechanism is used to detect whether the installation position 5 is equipped with a pneumatic component 4, so as to realize the automatic control of the drying mechanism of the grain processing device.

[0171] The positioning detection mechanism can employ a Hall effect sensor or a mechanical contact structure. When the positioning detection mechanism adopts a mechanical contact structure, it includes a detection unit and a triggering unit. The detection unit is located at each mounting position 5, and the triggering unit is located at the aerodynamic component 4. When the aerodynamic component 4 is installed at a certain mounting position 5, the detection unit at that mounting position 5 is triggered, and the detection unit sends a detection signal. The grain processing device then obtains the installation position information of the aerodynamic component 4 installed at that mounting position 5.

[0172] In one embodiment of this application, the grain processing apparatus further includes an interactive interface disposed on the outer wall of the housing 1, and the interactive interface is used for the user to input the installation position information of the aerodynamic component 4.

[0173] See Figure 1 As shown, the grain processing device also includes an interactive interface, which is located on the display screen 12. The interactive interface is used by the user to input the installation position information of the aerodynamic component 4. Of course, this interactive interface also has other control functions, such as: power on / off button, rice milling speed adjustment, etc., which will not be described in detail here.

[0174] In one embodiment of this application, the aerodynamic component 4 includes a heating module 401, which is used to heat the airflow passing through the aerodynamic component 4.

[0175] In order to dry the inside of the housing 1 at high temperature, the aerodynamic component 4 includes a heating module 401. The heating module 401 is used to heat the airflow passing through the aerodynamic component 4 to increase the temperature of the drying airflow, realize high-temperature rapid drying, speed up the drying process, and improve the drying and dehumidification effect.

[0176] In other embodiments, the aerodynamic component 4 can be injection molded entirely from PP (Polypropylene) or ABS (Acrylonitrile Butadiene Styrene) engineering plastics. This material provides the aerodynamic component 4 with a temperature resistance exceeding 100°C, supporting high-temperature drying environments.

[0177] See Figures 4-5 As shown, the aerodynamic component 4 includes a motor 402 and a fan blade 403. The motor 402 drives the fan blade 403 to rotate, generating an airflow for drying. A heating module 401 is positioned in the path of the airflow. The heating module 401 includes a heating module ventilation hole 4011. The airflow generated by the fan blade 403 is heated when it passes through the heating module ventilation hole 4011, forming a high-temperature drying airflow. A sealing ring 404 is also provided on the outer wall of the aerodynamic component 4. When the aerodynamic component 4 is installed with the mounting position 5, the sealing ring 404 can enhance the sealing between the aerodynamic component 4 and the inner wall of the mounting position 5. The aerodynamic component 4 also includes multiple screws 405, which allow for quick installation of the aerodynamic component 4 with the mounting position 5, facilitating replacement and maintenance.

[0178] Of course, in other embodiments, when the aerodynamic component 4 does not include the heating module 401, it can also dry at least a local area inside the housing 1. In this case, the drying process of the drying mechanism is low-temperature drying. Low-temperature drying can reduce the loss of nutrients in the grain, retain the nutrition and quality of the grain, and the energy consumption of low-temperature drying is low.

[0179] In one embodiment of this application, the grain processing apparatus is a rice milling machine.

[0180] In one embodiment, the grain processing device can be a rice milling machine, such as a household rice milling machine, which can dehull paddy rice and turn it into fresh rice such as brown rice, germ rice, and polished white rice. This rice milling machine has functions such as dehulling, grinding, and rice discharge, and features low noise, compatibility with multiple rice varieties, and fully automatic quantitative feeding.

[0181] The grain processing device of this application supports platform-based development. All interface structures (mounting position 5) and control logic adopt a unified standard and can be reused in different models of rice milling machines, which can significantly reduce development costs and production complexity.

[0182] The grain processing device of this application solves the technical problems of fixed airflow, poor adaptability, and difficulty in adapting to various overall machine layouts in existing rice milling drying systems. It achieves the technical effects of improving system layout flexibility, ensuring dehumidification consistency, and supporting platform-based development. Furthermore, it solves the technical problem of limited fan installation positions leading to non-reconfigurable airflow, achieving the technical effect of constructing a complete forced convection airflow path even when the fan is installed in different positions. It also solves the technical problems of poor sealing and inconvenient disassembly / reassembly of traditional air duct interfaces, achieving the technical effect of consistent airtightness under different layouts through universal quick-connect interfaces and silicone sealing rings. Moreover, it solves the technical problem of dehumidification blind spots caused by structural changes, achieving the technical effect of covering mainstream overall machine structures with three typical airflow modes and ensuring uniform airflow distribution inside the casing 1. Furthermore, it solves the cost problem of repeatedly developing airflow systems for multiple product models, achieving the technical effect of supporting platform-based development and reducing R&D and manufacturing costs through modular airflow design and main control self-identification function.

[0183] This embodiment also provides a control system applied to the above-mentioned grain processing device. The control system includes a main control module, the signal input terminal of which is electrically connected to the interactive interface and / or the positioning detection mechanism, and the signal output terminal of which is electrically connected to the aerodynamic component 4.

[0184] This control system is applied to the aforementioned grain processing device and is used to control the overall operation of the grain processing device. The control system includes a main control module. The signal input terminals of the main control module are electrically connected to the interactive interface and / or the positioning detection mechanism. The main control module's signal input terminals, connected to the interactive interface, can obtain input information from the interactive interface. The main control module's signal input terminals, connected to the positioning detection mechanism, can obtain detection information from the positioning detection mechanism. The main control module's signal output terminals are electrically connected to the aerodynamic component 4 to control the operation of the aerodynamic component 4 based on the aforementioned input or detection information.

[0185] Of course, the main control module is also electrically connected to other mechanisms of the grain processing device. For example, the main control module is also electrically connected to the grain processing mechanism to control the grain processing process, which will not be described in detail here.

[0186] In one embodiment of this application, the signal input terminal of the main control module is also electrically connected to the humidity detection element 11.

[0187] The signal input terminal of the main control module is also electrically connected to the humidity detection element 11 to obtain the humidity value detected by the humidity detection element 11. The main control module can adjust the drying process according to the detection value of the humidity detection element 11 to realize the drying feedback regulation of the grain processing device and improve the accuracy of drying and dehumidification control.

[0188] In one embodiment of this application, the main control module has a pre-installed control program, which includes a first control subroutine that matches the aerodynamic component 4 individually installed at each mounting position 5 and a second control subroutine that matches the aerodynamic component 4 installed at at least two mounting positions 5.

[0189] The main control module has a pre-installed control program, which is used to control the operation of the aerodynamic component 4 under different conditions.

[0190] In the same product, only one mounting position 5 can be used to install the aerodynamic component 4; that is, only one mounting position 5 is used in the product. The control program includes a first control subroutine matched to the individual installation of the aerodynamic component 4 at each mounting position 5. The first control subroutine mainly controls the aerodynamic component 4 at the mounting position 5 according to the setting position of different mounting positions 5 and their corresponding air duct paths.

[0191] In the same product, at least two mounting positions 5 can be used to install aerodynamic components 4. For example, two or three mounting positions 5 can be used to install aerodynamic components 4. In this product, multiple mounting positions 5 are used. The control program includes a second control subroutine that matches the at least two mounting positions 5 where aerodynamic components 4 are installed. The second control subroutine mainly controls the aerodynamic components 4 on the multiple mounting positions 5 according to the different mounting positions 5 and their corresponding air duct paths.

[0192] In one embodiment of this application, each first control subroutine corresponds to an operating mode of the aerodynamic component 4. The operating modes include a first operating mode, a second operating mode, and a third operating mode. The first operating mode matches the case where the aerodynamic component 4 is provided at the first mounting position 501, the second operating mode matches the case where the aerodynamic component 4 is provided at the second mounting position 502, and the third operating mode matches the case where the aerodynamic component 4 is provided at the third mounting position 503.

[0193] When there are multiple mounting positions 5, and each mounting position 5 is equipped with an aerodynamic component 4, the number of first control subroutines is the same as the number of mounting positions 5. For example, when there are three mounting positions 5 in the product, there are three first control subroutines, and each first control subroutine corresponds to the operating mode of the aerodynamic component 4 installed on one mounting position 5.

[0194] Specifically, each first control subroutine corresponds to an operating mode of the aerodynamic component 4. The operating modes include a first operating mode, a second operating mode, and a third operating mode. The first operating mode matches the case where the aerodynamic component 4 is installed at the first mounting position 501, the second operating mode matches the case where the aerodynamic component 4 is installed at the second mounting position 502, and the third operating mode matches the case where the aerodynamic component 4 is installed at the third mounting position 503.

[0195] In other words, when the first mounting position 501 is equipped with the aerodynamic component 4, the main control module executes the first control subroutine corresponding to the first mounting position 501, and the aerodynamic component 4 operates in the first operating mode. When the second mounting position 502 is equipped with the aerodynamic component 4, the main control module executes the first control subroutine corresponding to the second mounting position 502, and the aerodynamic component 4 operates in the second operating mode. When the third mounting position 503 is equipped with the aerodynamic component 4, the main control module executes the first control subroutine corresponding to the third mounting position 503, and the aerodynamic component 4 operates in the third operating mode.

[0196] In one embodiment, when the aerodynamic component 4 operates in the first operating mode, it operates in a high-pressure mode with a rotational speed of 3200 rpm for 15 minutes. When the aerodynamic component 4 operates in the second operating mode, it operates in a long-cycle low-speed mode with a rotational speed of 2600 rpm for 20 minutes. When the aerodynamic component 4 operates in the third operating mode, it operates in a high-pressure mode with a rotational speed of 3200 rpm for 15 minutes.

[0197] In one embodiment, the main control module has pre-stored air resistance models and control parameter libraries for three air duct paths, including rated fan speed, start-up delay, running time and humidity feedback adjustment logic. Based on the above air resistance models and control parameter libraries, the operating parameters of the aerodynamic component 4 in different operating modes are constructed.

[0198] This embodiment also provides a control method, executed by the above-mentioned control system, the control method including:

[0199] Obtain the installation location information of aerodynamic component 4;

[0200] The corresponding control program is executed according to the installation location information to control the operation of the aerodynamic component 4.

[0201] This control method can alter the drying control process based on adjustments to product appearance design, internal module layout, or functional integration, significantly improving the flexibility and adaptability of the overall system layout. It meets the needs of various model system layouts and strongly supports product platform and serialization development. While ensuring drying and dehumidification performance, it reduces redundant mold making, significantly shortens the development cycle, lowers R&D and manufacturing costs, and enhances the competitiveness and iteration efficiency of the product series.

[0202] In one embodiment of this application, the step of obtaining the installation position information of the aerodynamic component 4 includes: obtaining the installation position information by obtaining the user input signal of the interactive interface, or obtaining the installation position information by obtaining the detection signal of the positioning detection mechanism.

[0203] In the step of obtaining the installation position information of the aerodynamic component 4, the installation position information of the aerodynamic component 4 can be obtained through various means.

[0204] In one embodiment, the interactive interface is provided with selection buttons (or touch points) for each mounting position 5. Users can operate on the interactive interface to input which mounting position 5 is equipped with aerodynamic components 4. The main control module obtains the installation position information of aerodynamic components 4 through the user input signal.

[0205] In one embodiment, a positioning detection mechanism is provided on the mounting position 5. The positioning detection mechanism can send a detection signal to the main control module so that the main control module can obtain the installation position information of the aerodynamic component 4.

[0206] In one embodiment of this application, after executing the corresponding control program according to the installation location information to control the operation of the aerodynamic component 4, the method further includes: obtaining the humidity detection result of the humidity detection element 11 and adjusting the airflow of the aerodynamic component 4 according to the humidity detection result.

[0207] The grain processing device is equipped with a humidity detection element 11. After executing the corresponding control program according to the installation location information and controlling the operation of the aerodynamic component 4, the device also includes: obtaining the humidity detection result of the humidity detection element 11 and adjusting the air volume of the aerodynamic component 4 according to the humidity detection result. This allows the drying process to be adjusted according to the actual air humidity inside the machine, thereby achieving humidity feedback regulation and improving the reliability of drying control.

[0208] The control method of this application will be described below with reference to the accompanying drawings:

[0209] Step S01: Obtain the installation position information of aerodynamic component 4.

[0210] The main control module has a pre-installed control program, which includes a first control subroutine and a second control subroutine. The main control module calls the corresponding control subroutine based on the installation location information of the aerodynamic component 4. In other words, the main control module needs to first determine which installation position 5 is equipped with the aerodynamic component 4, and then call the corresponding control subroutine.

[0211] In one embodiment, the interactive interface is provided with selection buttons (or touch points) for each mounting position 5. Users can operate on the interactive interface to input which mounting position 5 is equipped with aerodynamic components 4. The main control module obtains the installation position information of aerodynamic components 4 through the user input signal.

[0212] In one embodiment, a positioning detection mechanism is provided on the mounting position 5. The positioning detection mechanism can send a detection signal to the main control module so that the main control module can obtain the installation position information of the aerodynamic component 4.

[0213] Step S02: Execute the corresponding control program according to the installation location information to control the operation of the aerodynamic component 4.

[0214] After the main control module learns which or which mounting positions 5 are equipped with aerodynamic components 4, it calls the corresponding control subroutine to control the operation of the corresponding aerodynamic components 4, so that the aerodynamic components 4 are in the most suitable working mode to achieve the best drying and dehumidification effect.

[0215] Specifically, when the first mounting position 501 is equipped with a separate aerodynamic component 4, the aerodynamic component 4 operates in the first operating mode, that is, the aerodynamic component 4 operates in the high wind pressure mode, the rotation speed of the aerodynamic component 4 is 3200 rpm, and the operating time is 15 minutes.

[0216] When the second mounting position 502 is equipped with a separate aerodynamic component 4, the aerodynamic component 4 operates in the second operating mode, that is, the aerodynamic component 4 operates in the long cycle low speed mode, the rotation speed of the aerodynamic component 4 is 2600 rpm, and the operating time is 20 minutes.

[0217] When the third mounting position 503 is equipped with a separate aerodynamic component 4, the aerodynamic component 4 operates in the third operating mode, that is, the aerodynamic component 4 operates in the high wind pressure mode, the rotation speed of the aerodynamic component 4 is 3200 rpm, and the operating time is 15 minutes.

[0218] Step S03: Obtain the humidity detection result of the humidity detection component 11, and adjust the air volume of the aerodynamic component 4 according to the humidity detection result.

[0219] During the operation of the aerodynamic component 4, the main control module acquires the humidity detection results of the humidity detection component 11 in real time, and adjusts the airflow of the aerodynamic component 4 according to the humidity detection results, so that the operating parameters of the aerodynamic component 4 are more matched with the humidity conditions inside the housing 1, realizing the humidity feedback adjustment logic and forming a closed control.

[0220] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0221] The above embodiments merely illustrate several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
