technical field

The invention relates to the technical field of grain processing, in particular to an airflow type vibration bran beater.

Background technique

As an auxiliary screening equipment for the milling process, the bran beater is mainly used in the middle/backward skin milling system of the milling process to process the coarsely screened bran flakes, so as to reduce the load of the subsequent skin milling and improve the grinding efficiency. , or reduce the flour content of bran. The main function of the bran beater is that the material enters the working cylinder sieve and is hit by the beater rotor, so that the powder adhering to the bran flakes is separated from it and passes through the sieve hole to become the sieve, while the bran flakes remain in the sieve cylinder. The inside is discharged from the discharge port.

At present, the commonly used bran beater is mainly a single mechanical beater type bran beater. The pure mechanical bran beater often causes the bran to be broken, and the flour on the bran is not cleaned. In addition, the transmission part of the conventional bran beater adopts The connection of the belt conveyor reducer is prone to vibration and noise; the equipment structure adopts the overall structure, which is not easy to replace and maintain.
