A recovery component is arranged below the impurity collection box 11, a collecting hopper 12 is welded inside the screening box 1, and a collection box 13 is arranged on the bottom inner wall of the screening box 1.

[0028] During screening, starch is put into the conveyor belt 5 through the feed hopper 3, and the starch is dried by the heating tube 6. The dried starch falls into the grinding assembly for grinding under the transportation of the conveyor belt 5, and the ground starch falls into the screening plate 9 for screening. The screening plate 9 is vibrated by the vibration motor 10 to speed up the screening efficiency. The screened starch falls into the collecting box 13 through the collecting hopper 12, and the impurities left after screening roll into the impurity collection box 11 through the inclined surface of the screening plate 9.

[0029] The starch is dried by the heating tube 6 to reduce the water content of the starch, thereby improving the efficiency and quality of subsequent grinding and providing a certain guarantee for the quality of vermicelli production.

[0030] In order to effectively recycle raw materials, such as Figure 2 , Figure 3 As shown, the grinding assembly includes a grinding block 7, and the grinding block 7 is fixed on both sides of the inside of the screening box 1. A plurality of grinding rollers 8 are rotatably connected inside the screening box 1, and the grinding rollers 8 cooperate with the grinding block 7. A fixing frame 20 is welded to the outer wall of one side of the screening box 1, and a motor 19 is fixed inside the fixing frame 20 by bolts. A gear box 18 is installed on the outer wall of one side of the screening box 1, and the output shaft of the motor 19 is driven and matched with the input shaft of the gear box 18, and the output shaft of the gear box 18 is driven and matched with the grinding roller 8.

[0031] When the dried starch falls into the grinding assembly, the motor 19 is started, driving the multiple grinding rollers 8 to rotate through the gear box 18, and the starch is ground by the pressure between the grinding rollers 8 and the pressure between the grinding rollers 8 and the grinding blocks 7.

[0032] The grinding component can grind and refine the starch, effectively improving the screening efficiency and the starch recovery effect.

[0033] In order to recover starch mixed with impurities, such as Figure 2 As shown, the recovery assembly includes a recovery pipe 14, a recovery box 16 and an air pump 15.

A filter screen is arranged at one end of the recovery pipe 14 connected to the impurity collection box 11.

[0034] While the starch is being screened, the suction pump 15 is started. The suction force generated by the suction pump 15 sucks the starch mixed with impurities into the recovery pipe 14 and into the filter bag 17 for collection, thereby avoiding the waste of raw materials.

[0035] Working principle: During screening, starch is put into the conveyor belt 5 through the feed hopper 3, and the starch is dried through the heating tube 6. The dried starch falls into the grinding assembly under the conveyance of the conveyor belt 5, and the motor 19 is started, and the multiple grinding rollers 8 are driven to rotate through the gear box 18. The starch is ground by the pressure between the grinding rollers 8 and the pressure between the grinding rollers 8 and the grinding block 7. The ground starch falls into the screening plate 9, and the starch is screened under the action of the vibration motor 10. The screened starch falls into the collection box 13 through the collecting hopper 12, and the impurities left after screening roll into the impurity collection box 11 through the inclined surface of the screening plate 9. At the same time, the suction pump 15 is started, and the suction force generated by the suction pump 15 sucks the starch mixed in the impurities into the recovery pipe 14 and enters the filter gauze bag 17 for collection.
