Abstract
Description
Technical Field
[0001] This utility model relates to an apparatus for lotus root starch production, and more particularly to a crushing and component screening apparatus for lotus root starch production. Background Technology
[0002] Lotus root starch production is the core processing step using lotus root as the raw material. It uses lotus root, an aquatic plant rich in starch, as the raw material and transforms it into a delicate and nutritious food through a series of key processes. This process not only requires precise control of technology, but also a deep understanding of the raw materials. The quality of each step is directly related to the quality of the final product.
[0003] In the traditional lotus root starch production process, each processing step is usually completed by independent equipment. For example, the crushing process is responsible for crushing fresh lotus roots into smaller particles for subsequent processing, and the screening process is used to separate out parts that are not suitable for processing. However, there are not only these steps, but the existing equipment lacks the function of completing multiple processing steps at the same time. The material handling in the middle process is not only time-consuming, but may also lead to material loss or contamination, affecting the quality of the final product. At the same time, it also makes the production process complicated and inefficient.
[0004] Therefore, it is necessary to design a crushing and component screening device for lotus root starch production. Utility Model Content
[0005] In order to overcome the shortcomings of existing production processes that lack integrated devices capable of completing multiple processing steps simultaneously, this utility model provides a crushing and component screening device for lotus root starch production.

A screen and a collecting frame are slidably connected in the lower part of the processing chamber. The screen slides up and down, while the collecting frame slides back and forth. The screen is located directly above the collecting frame. A shaking mechanism and a return mechanism are provided on the screen. A screening mechanism is provided on the upper rear side of the processing chamber.
[0007] To further explain, the material shaking mechanism includes pulleys, cams, and elastic elements. Cams are rotatably connected to the lower left and right sides of the processing chamber. The cams are all located below the screen and abut against the screen. Pulleys are wound around the central shaft of the gear set and the cams on the left and right sides. Multiple elastic elements connect the screen and the processing chamber.
[0008] To further explain, the return material mechanism includes a first push plate, a screw, a second motor, an electric slide rail, a return material plate, an electric push rod, and a second push plate. The first push plate is slidably connected to the screen mesh, and the first push plate is in contact with the screen mesh surface. The screw is rotatably connected to the right side of the screen mesh, and the screw is threadedly connected to the first push plate. The second motor is installed at the rear right side of the screen mesh, and the output shaft of the second motor is connected to the screw.

An electric push rod is installed on the upper rear side of the processing chamber, and the second push plate is slidably connected to the upper rear side of the processing chamber, and the second push plate is connected to the output shaft of the electric push rod. It should be noted that the space for the return material plate to slide up and down is located in a cavity on the rear side of the processing chamber, and the upper and lower parts of this cavity are connected to the interior of the processing chamber.
[0009] To further explain, the screening mechanism includes a blower plate, blowers, and a discharge port. A blower plate is located on the upper rear side of the processing chamber, below the second push plate. Multiple blowers are installed on the front side of the blower plate. The blower plate faces the upper part of the rear cavity of the processing chamber, and a discharge port is located on the rear part of the processing chamber facing the blower plate.
[0010] To further explain, it also includes foot pads, with foot pads installed at the front, back, and left and right sides of the bottom of the processing chamber.

Detailed Implementation
[0022] Example: A crushing and component screening device for lotus root starch production, such as... Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, the system includes a processing chamber 1, a feeding frame 2, a gear set 3, a first motor 4, crushing rollers 5, a screen 7, a collection frame 10, a shaking mechanism, a return mechanism, and a screening mechanism. The upper part of the processing chamber 1 is connected to and communicates with the feeding frame 2. Crushing rollers 5 are rotatably connected to the upper left and right sides of the processing chamber 1. The tooth patterns between the two crushing rollers 5 are complementary. A gear set 3 is provided on the front side of the processing chamber 1. The front sides of the two crushing rollers 5 are connected by the spur teeth of the gear set 3 to achieve synchronous rotation in opposite directions. The first motor 4 is installed on the front right side of the processing chamber 1. The output shaft of the first motor 4 is connected to the gear on the same side of the gear set 3. The screen 7 and the collection frame 10 are slidably connected in the lower part of the processing chamber 1. The screen 7 slides up and down, while the collection frame 10 slides back and forth. The screen 7 is located directly above the collection frame 10. The screen 7 is equipped with a shaking mechanism and a return mechanism. A screening mechanism is provided on the upper rear side of the processing chamber 1.
[0023] When using this equipment, the operator needs to start the first motor 4 to drive the gear set 3 to drive the two crushing rollers 5 to rotate in opposite directions. Then, the cleaned fresh lotus root is poured from the feeding frame 2 into the processing chamber. The complementary toothed surface will squeeze and crush the lotus root pieces, and the crushed slurry will fall to the top of the screen 7.
[0024] like Figure 2 , Figure 3 and Figure 4 As shown, the material shaking mechanism includes a pulley 6, a cam 8, and an elastic element 9. The lower left and right sides of the processing chamber 1 are rotatably connected to the cam 8. The cam 8 is located below the screen 7 and abuts against the screen 7. The central shaft of the gear set 3 is connected to the pulley 6 between the cam 8 on the left and right sides. Multiple elastic elements 9 are connected between the screen 7 and the processing chamber 1. The elastic element 9 is a spring.
[0025] Next, as the gear set 3 rotates, it drives the cam 8 to rotate through the pulley 6 and periodically pushes the screen 7 to vibrate up and down, thus avoiding clogging. The elastic element 9 provides a restoring force, allowing the finely crushed starch to pass through the screen 7 more quickly and enter the collection frame 10, while larger raw materials and fiber residue generated during crushing will remain on the surface of the screen 7.
[0026] like Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the return mechanism includes a first push plate 12, a screw 13, a second motor 14, an electric slide rail 15, a return plate 16, an electric push rod 17, and a second push plate 18. The first push plate 12 is slidably connected to the screen 7, and the first push plate 12 is in contact with the surface of the screen 7. The screw 13 is rotatably connected to the right side of the screen 7, and the screw 13 is threadedly connected to the first push plate 12. The second motor 14 is installed at the rear right side of the screen 7, and the output shaft of the second motor 14 is connected to the screw 13. The longitudinal direction of the rear side inside the processing chamber 1... An electric slide rail 15 is installed, and a return plate 16 is slidably connected to the electric slide rail 15. The return plate 16 is initially horizontal with the screen 7. An electric push rod 17 is installed on the upper rear side of the processing chamber 1. A second push plate 18 is slidably connected to the upper rear side of the processing chamber 1. The second push plate 18 is connected to the output shaft of the electric push rod 17. It should be noted that the space for the return plate 16 to slide up and down is located in a cavity on the rear side of the processing chamber 1. The upper and lower parts of this cavity are connected to the interior of the processing chamber 1.
[0027] like Figure 2 , Figure 3 , Figure 5 and Figure 6As shown, the screening mechanism includes a blower plate 19, a blower 20, and a discharge port 102. The blower plate 19 is located on the upper rear side of the processing chamber 1. The blower plate 19 is located below the second push plate 18. Multiple blowers 20 are installed on the front side of the blower plate 19. The blower plate 19 is directly opposite the upper part of the rear cavity of the processing chamber 1, and the discharge port 102 is located on the rear part of the processing chamber 1 directly opposite to the blower plate 19.
[0028] When a large amount of large particles and fiber residue remain on the screen 7, the operator can drive the screw 13 to rotate via the second motor 14, simultaneously pushing the first push plate 12 backward to push the fiber residue and large particles on the screen 7 onto the return plate 16 in the rear cavity of the processing chamber 1. Next, the operator needs to activate the electric slide rail 15 to raise the return plate 16, connecting it to the crushing area within the processing chamber 1. During this process, the operator also needs to activate the blower 20 to generate a strong and stable airflow. This airflow is evenly distributed through multiple outlets on the blower plate 19, blowing onto the material on the return plate 16. Utilizing aerodynamic principles, lightweight impurities like fibers are carried away by the airflow and discharged through the discharge port 102, while heavier, qualified materials remain in place, waiting to return to the crushing area for further processing. Then, the operator can activate the electric push rod 17 to drive the second push plate 18 forward, helping the material return from the return plate 16 to the crushing area for further processing, thus achieving an efficient screening process.
[0029] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 6 As shown, it also includes foot pads 101 and handles 11. Foot pads 101 are provided on the front, back and left and right sides of the bottom of the processing chamber 1. A handle 11 is welded to the front of the collection frame 10. The foot pads 101 can increase the stability of the equipment and reduce vibration and noise during operation. The handles 11 make it easy for operators to pull out for cleaning or sampling.
