The Precleaner removes the light materials like dust, husk and chaff using the air flow from the fan. The grain is lead in and spread out over the air intake slats. The movement of the grain over the slats releases the light material from the grain and they are being sucked out though the fan. The grain is dropping into the outlet hopper.
Area of use
The Precleaner is used for cleaning light materials from the grain. It is mounted directly under the bucket elevator outlet. The low build in height makes it possible to clean the grain using only one bucket elevator. Other types of precleaners often requires 2 elevators. The Precleaner is placed as a central part of the conveying system. Thus it can be used both to convey moist grain in, and dry grain out. The best effect is achieved when the material is dry.
