Description

A soybean cleaning machine for dried bean curd production Technical Field

[0001] This utility model relates to the field of dried bean curd production, and in particular to a soybean cleaning machine for dried bean curd production. Background Technology

[0002] As a traditional soy product loved by consumers, dried bean curd sticks occupy an important position in the food market due to their unique taste and rich nutritional value. In the production process of dried bean curd sticks, soybeans are the core raw material, and their quality directly determines the quality and taste of the final product. High-quality soybean raw materials not only need to have good nutritional components, but also require extremely low impurity content to ensure the stability of the production process and the consistency of product quality.

[0003] The current method for cleaning soybeans used in the production of dried bean curd sticks usually involves pouring soybeans into a cleaning device for filtration and impurity removal, followed by collection of the cleaned soybeans. However, most of the current equipment focuses on filtration and impurity removal and does not have a cleaning function. After filtration, a large amount of mud, dust and some residual impurities will still be attached to the surface of the soybeans, resulting in poor cleaning effect and affecting the quality of soybeans and dried bean curd sticks.

[0004] Therefore, it is necessary to design a soybean cleaning machine for tofu skin production that can filter and remove impurities from soybeans multiple times while washing them, reducing impurity residue, improving the cleaning effect, improving the quality of soybeans, and being easy to use. Summary of the Invention

[0005] To overcome the shortcomings of current equipment, which mostly focuses on filtration and impurity removal but lacks cleaning functions, resulting in soybeans still having a large amount of mud, dust, and some residual impurities adhering to their surface after filtration alone, leading to poor cleaning effect and affecting the quality of soybeans and dried bean curd production, this utility model provides a soybean cleaning machine for dried bean curd production that can perform multiple filtrations and impurity removals while simultaneously cleaning soybeans, reducing impurity residue, improving cleaning effect, improving soybean quality, and being easy to use.

[0006] The technical solution of this utility model is: a soybean cleaning machine for bean curd production, including a frame, a hopper, an adjusting plate, a screening and cleaning component and a dirt removal component. The hopper is connected to the upper part of the frame, and the adjusting plate is slidably connected to the lower part of the hopper. The screening and cleaning component for filtering, screening and rinsing soybeans is provided on the frame, and a dirt removal component for preliminary dirt removal of soybeans is provided on the upper right part of the frame.

[0007] As an improvement to the above solution, the hopper is wider at the top and narrower at the bottom.

[0008] As an improvement to the above solution, the screening and cleaning assembly includes a filter screen, a screening frame, a water outlet frame, a dual-shaft motor, an eccentric wheel, a rotating component, a spray pipe, and a guide frame. The right side of the frame is connected to two guide frames, one in front and one behind. The screening frame is slidably connected between the guide frames. The upper left and lower right sides of the screening frame are slidably engaged with the filter screen. The lower part of the guide frames is connected to the water outlet frame, which contacts the screening frame. The front of the frame is connected to a dual-shaft motor. An eccentric wheel is connected to the output shaft at the rear of the dual-shaft motor. A rotating component is rotatably connected to the eccentric wheel and is rotatably connected to the screening frame. The left side of the frame is connected to a spray pipe, which passes through the screening frame.

[0009] As an improvement to the above solution, a handle is provided on the back of each filter screen.

[0010] As an improvement to the above solution, the impurity removal component includes a blower, fan blades, an adjustment door, and a flat belt. The blower is connected to the upper right part of the frame, and the fan blades are rotatably connected to the upper right part of the frame. The fan blades are located inside the blower. The adjustment door is slidably connected to the upper part of the blower. A flat belt is wound around the output shaft of the dual-axis motor and the fan blades through a pulley.

[0011] As an improvement to the above solution, a collection box is also included, with collection boxes connected to the upper right side and the left rear side of the frame.

[0012] The beneficial effects of this utility model are as follows: 1. This utility model uses the rotation of the eccentric wheel to make the rotating part rotate and drive the screening frame to move up and down to screen the soybeans. The soybeans on the screening frame slide onto the filter screen for multiple impurity removal. At the same time, water is sprayed through the spray pipe to wash the soybeans before they are discharged and collected. This allows the soybeans to be filtered and cleaned multiple times, reducing impurity residue, improving the cleaning effect, improving the quality of the soybeans, and making it convenient to use.

[0013] 2. This utility model adjusts the air volume by pulling the adjustment door and the soybean output by pulling the adjustment plate, so that the soybeans fall onto the screening frame. The fan blades rotate and blow air, blowing the impurities in the soybeans to the left side of the frame for initial impurity removal. This allows the air volume and soybean output to be adjusted according to the needs to remove lighter impurities from the soybeans, facilitating subsequent processing and improving processing efficiency.

Detailed Implementation

[0020] The present invention will now be described more fully below with reference to the accompanying drawings, in which presently preferred embodiments of the invention are shown. However, the present invention may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided for thoroughness and completeness and to fully convey the scope of the invention to those skilled in the art.

[0021] A soybean cleaning machine for dried bean curd production, as shown in Figures 1-5, includes a frame 1, a hopper 2, an adjusting plate 3, a collection box 15, a screening and washing component, and a dirt removal component. The hopper 2 is connected to the upper part of the frame 1. The hopper 2 is wider at the top and narrower at the bottom for easy material feeding. The adjusting plate 3 is slidably connected to the lower part of the hopper 2. The collection box 15 is connected to the upper right side and the left rear side of the frame 1 to facilitate the separate collection of impurities and soybeans. The frame 1 is equipped with a screening and washing component for filtering, screening, and rinsing soybeans. The upper right side of the frame 1 is equipped with a dirt removal component for preliminary dirt removal from soybeans.

[0022] As shown in Figures 1-5, the screening and cleaning assembly includes a filter screen 4, a screening frame 40, a water outlet frame 5, an eccentric wheel 11, a rotating component 12, a spray pipe 13, and a guide frame 14. The right side of the frame 1 is connected to two guide frames 14, which are slidably connected to the screening frame 40. The upper left and lower right parts of the screening frame 40 are slidably engaged with the filter screen 4. Each filter screen 4 has a handle on its rear side for easy removal by hand. The lower part of the guide frames 14 is connected to the water outlet frame 5, which contacts the screening frame 40. The output shaft of the dual-axis motor 6 is connected to the eccentric wheel 11, and the rotating component 12 is rotatably connected to the eccentric wheel 11. The rotating component 12 is rotatably connected to the screening frame 40. The left side of the frame 1 is connected to the spray pipe 13, which passes through the screening frame 40.

[0023] As shown in Figures 1 and 2, the impurity removal assembly includes the dual-axis motor 6, the blower 7, the fan blades 8, the adjusting door 9, and the flat belt 10. The dual-axis motor 6 is connected to the front of the frame 1, the blower 7 is connected to the upper right of the frame 1, the fan blades 8 are rotatably connected to the upper right of the frame 1, the fan blades 8 are located inside the blower 7, the adjusting door 9 is slidably connected to the upper part of the blower 7, and the flat belt 10 is wound around the output shaft of the front of the dual-axis motor 6 and the fan blades 8 through a pulley.

[0024] When cleaning soybeans is required for tofu skin production, this device can be used. The frame 1 is brought into contact with the ground. The filter screen 4 is then lifted by the handle and brought into contact with the screening frame 40. The filter screen 4 is then moved for installation. The spray pipe 13 is then connected to a water source. The regulating gate 9 is pulled to adjust the airflow. After adjusting to a suitable position, soybeans are poured into the feeding hopper 2. The feeding hopper 2 is wider at the top and narrower at the bottom for easy feeding. The regulating plate 3 is then pulled to adjust the soybean discharge rate, causing the soybeans to fall from the feeding hopper 2 onto the screening frame 40. The device is activated simultaneously with the soybeans falling. The dual-axis motor 6 drives the pulley to rotate, which in turn rotates the flat belt 10, causing the fan blades 8 to rotate and blow air. The air is discharged from the blower 7 and collected in the collection box 15 on the left, thus blowing impurities from the soybeans to the left side of the frame 1 for initial impurity removal. This allows for adjustment of the airflow and soybean output as needed, facilitating the removal of lighter impurities and improving subsequent processing efficiency. Simultaneously, the dual-axis motor 6 drives the eccentric wheel 11 to rotate, causing the rotating component 12 to rotate... The movement of the screen 40 along the guide frame 14 causes it to slide down onto the upper filter screen 4 for sieving. Larger impurities remain on the upper filter screen 4, causing the soybeans to fall from the left side along the upper filter screen 4. Simultaneously, water is sprayed through the spray pipe 13 to rinse the soybeans. The soybeans then continue to move along the lower filter screen 4 from the right side to the right collection box 15 for collection. Smaller impurities remain on the lower filter screen 4, allowing the soybeans to fall back down. Water flows out from the lower filter screen 4, falls into the water outlet frame 5, and flows into the collection box 15 on the left for collection. This allows for multiple filtrations and cleaning of soybeans, reducing impurity residue, improving cleaning efficiency, and enhancing soybean quality. It is easy to use. After processing, the dual-shaft motor 6 is turned off, disconnecting the spray pipe 13 from the water source. Then, the filter screen 4 is removed by pulling the handle for cleaning, and the device is cleaned simultaneously. After cleaning, the adjusting plate 3 and the adjusting door 9 are pushed back to reset. The above operation is then repeated to reinstall the filter screen 4.

[0025] Although the present invention has been described in detail with reference to the above embodiments, it will be apparent to those skilled in the art that various changes or modifications can be made to the present invention without departing from the principles and spirit of the present invention as defined by the claims. Therefore, the detailed description of the embodiments in this disclosure is for explanation only and not for limiting the present invention, but rather the scope of protection is defined by the content of the claims.
