Fan blades of the special ventilator incorporated in the husk separator are not coming in contact with husk, paddy, or cargo rice. Thus, these blades are not subject to wear. The uniform air distribution over the entire width of the working chamber and a new concept of the separation chamber ensures a high degree of separation efficency. A cyclone or sleeve filter with ventilator, dust lock etc. are unnecessary. An insignificant amount of air out of the closed circuit system is expelled by the discharge augers into the piping system.
Operation is practically noiseless.
The spearation chamber is illuminated and inspection windows permit easy observation and adjustment of the separation efficiency. The paddy enters into the spring-suspended feeding hopper. On increasing paddy level, the feeding hopper lowers and actuates a pneumatic valve prior to reaching its bottom position. The pneumatic valve starts automatic operation. At this stage, the inlet gate provided in the feeding hopper opens and at the same time the movable roll advances towards the fixed roll.
