The function of the powder cleaning system of wheat flour processing equipment: When cleaning the powder, the coarse grains and coarse flours from the skin mill, slag mill or the former center mill are selected and divided into wheat husks, bran flour grains and pure endosperm grains according to their quality. And the pure endosperm stored separately is sent to the corresponding heart grinder to improve the quality of flour according to different quality.
The material entering the powder cleaner must first be classified and sifted flour to ensure that the particle size of the material entering the machine is uniform. Choose a suitable screen and be equipped with an appropriate amount of air flow to ensure the powder cleaning effect. Otherwise, the powder cleaning material is mixed with flour or the particle size is too large, which will reduce the cleaning effect.
The unit flow rate of the powder cleaning system of the wheat flour processing equipment: the unit flow rate of the powder cleaner is mainly related to the thickness of the particles, the bulk density, the size of the sieve and the air suction volume. When the bulk density of the particles is high, the fluidity is good, the sieve of the powder cleaner is properly thinned, and the suction volume is increased by an appropriate amount, the unit flow rate of the powder cleaner should be taken as the upper limit, otherwise the lower limit should be taken.
