Rice destoner machine is an indispensable impurity removal equipment in flour mills. It is mainly used to remove side stones mixed with wheat seeds to reduce the sand content of flour and ensure the quality of flour. If you know the working principle and operation of the rice destoner machine, you don't know why it is, it will definitely not help to improve the process effect of the rice destoner machine.
Stone sieve is the main working mechanism of the rice destoner machine. After the material enters the stone removal sieve surface, due to the difference in the suspension speed of the side-by-side stone and wheat, under the combined action of appropriate vibration and updraft, the wheat with a lower suspension speed floats on the upper layer, and the side-by-side stone with a higher suspension speed sinks into the The bottom layer is close to the sieve surface, forming an automatic classification phenomenon. At the same time, due to the effect of air flow, the gap between materials increases, and the positive pressure and friction between materials are reduced. Being in a fluid state, this further promotes the formation of automatic classification.
The upper layer material with a lower suspension speed is driven by gravity, inertia force, air flow and continuous feeding. The lower layer material is a sliding surface, which is slid down to the wheat exit relative to the stone removal sieve surface. In the process of the upper layer material sliding, the suspension is suspended. Debris such as side-by-side stones with higher speed gradually separated from the material layer and entered the lower layer. The stones and unsuspended wheat in the lower layer slide along the sieve surface under the action of vibration, and the wheat enters the upper layer in a semi-suspended state. When the upper surface of the stone-removing sieve is reached, the lower layer contains less wheat. The wheat was blown back into the wheat stream by the anti-air current, and the side-by-side stones continued to climb up through the stone exit.
