[0094] When the device is in use, the sealed feeding mechanism 6 is opened for feeding. After feeding, the sealed feeding mechanism 6 is closed. On the premise of ensuring that the sealed discharge hopper 4 and the sealed slag discharge structure 5 are closed, the main body 1 of the electric vibrating screen is started to realize vibrating screening. The upper end of the main body 1 of the electric vibrating screen is hermetically fixed to the strip-shaped cover 2 through the sealed connection structure 3. The above structures cooperate to make the whole device a fully sealed structure, avoiding the leakage of dust generated during the vibrating screening process.

[0095] After the vibrating screening is completed, the negative pressure dust suction device 8 is used to suck away the dust generated during the screening of the food raw materials. After the negative pressure dust suction device 8 is opened for a sufficient time to complete the dust suction, the sealed discharge hopper 4 is opened for discharging, and the sealed slag discharge structure 5 is opened for slag discharge.
