The anti-falling automatic screening device for the fermented glutinous rice
leavening agent comprises a screening structure and a feeding structure matched with the screening structure, the screening structure comprises a bottom frame, the bottom frame is connected with a screening groove through a plurality of sets of elastic supporting pieces, the screening groove is provided with a plurality of sets of screening holes, a
vibration source and a shielding structure, and the discharging end of the screening groove is provided with a discharging matching structure and an opening and closing structure. A guide groove matched with the multiple sets of screen holes is formed in the bottom frame, and a collecting box is arranged at the discharging end of the guide groove. By the adoption of the structure, material storing and sorting are matched with feeding, materials are guided to be fed through the inclined face, the materials are sequentially sorted, the feeding
route is separated, direct falling and collision are avoided through back-and-forth guiding of the inclined plate, leavening agents are prevented from falling and dispersing,
raw material piles can be dispersed, feeding is orderly conducted, and the
screening effect is improved; in the screening process, the open ends are in closed fit, raw materials are prevented from turning over in the vibration screening process, and practicability is extremely high; and the material receiving position is rapidly switched, manual material receiving is avoided, and the
machining efficiency is improved.
