Some lumps of flour are broken up by the stirring roller 7, and at the same time, the dust generated during the stirring process is sucked into the filter box 25 through the exhaust pipe 2 by the fan 27 to prevent the dust from escaping. After the stirring is completed, the push rod of the electric telescopic rod 11 is retracted to open the baffle plate 4, and the flour in the stirring chamber 5 falls onto the first screening frame 13, and the iron sheet 19 is repeatedly adsorbed by the electromagnet 20 to make the first screening frame 13 and the second screening frame 15 vibrate, and the granular impurities in the flour are screened out by the screen 16, and the flour is discharged from the box body 1 through the discharge port 21 for subsequent production and processing. The dust generated during the screening process is adsorbed into the filter box 25 through the exhaust branch pipe 28, thereby ensuring that the dust generated during the screening process will not escape to the outside of the equipment to pollute the environment, thereby ensuring the health of the operator.
