A pad 308 is fixedly installed on the upper part of the inner wall of the cleaning tank 1. A splash guard plate 309 is clamped on the upper surface of the pad 308.
[0026] More specifically, after disassembling the snap-fit plate 307 and putting the flour raw material into the connecting column cylinder 305, the snap-fit plate 307 is snapped and installed, so that the snap-fit plate 307 and the connecting column cylinder 305 are snapped and connected. After installing the anti-splash mesh plate 309 on the upper surface of the pad block 308, the cover plate 102 is covered, and the external power supply is connected to power the motor 301. The output end of the motor 301 drives the transmission shaft 302 to rotate, thereby driving the several stirring blades 303 set on the outer surface of the transmission shaft 302 to rotate, and stirring and cleaning the flour raw material in the connecting column cylinder 305.
[0027] A water spray assembly 4 is installed in the upper part of the cleaning tank 1; such as Figure 3 As shown, specifically, the water spray assembly 4 includes a water tank 401 located on one side of the cleaning tank 1. A water inlet pipe 402 is fixedly installed on one side of the upper surface of the water tank 401, and a connecting pipe 403 is fixedly connected to the other side of the upper surface of the water tank 401. A pump 404 is fixedly installed on the upper part of one side of the outer surface of the cleaning tank 1. The input end of the pump 404 is fixedly connected to one end of the connecting pipe 403.

The nozzle seats 405 are symmetrically distributed on both sides of the upper part of the inner wall of the cleaning tank 1. A water supply pipe 407 is fixedly connected between the two nozzle seats 405.
[0028] More specifically, the water inlet pipe 402 is connected to a water source to store water in the water tank 401. The pump 404 is operated to draw water from the water tank 401 through the connecting pipe 403 and pump it into the nozzle seat 405. The water is then sprayed out through the nozzle 406. The nozzle 406 on the other side delivers water through the water supply pipe 407, which is fixedly connected to one side of the water supply pipe 407. Several nozzles 406 on both sides spray water to rinse the flour raw materials in the connecting column cylinder 305.

The wastewater flows into the purification tank 501 and is filtered and purified by several filter mesh plates 503. Then, it flows back to the water tank 401 for use through the installation pipe 504.
[0031] In summary, this raw material cleaning device for flour processing stores water in the water tank 401. After placing the flour raw materials in the connecting cylinder 305, the motor 301 is operated. The output end of the motor 301 drives the transmission shaft 302 to rotate, thereby driving the stirring plate 303 to rotate and agitate the raw materials in the connecting cylinder 305. At the same time, the pump 404 draws water from the water tank 401 through the connecting pipe 403 and pumps it out through the nozzle 406. The nozzle 406 sprays water onto the connecting cylinder 305 to agitate and clean the flour raw materials. The wastewater and impurities from the cleaning flow to the bottom of the cleaning tank 1 and are guided by the water guide plate 104. The wastewater flows into the purification tank 501 and is filtered and purified by several filter screens 503 set on the inner wall of the purification tank 501.
