PPR    ROTARY PRE-CLEANER

Rotary pre-cleaner Mod.PPR Use
This pre-cleaner is designed for simple, fast removal of light and heavy (rubble) impurities in the cereal.
It is essential for the quality of the cereal that a pre-cleaner is installed at the dryer inlet, as it homogenizes the product, preventing clogging and reducing energy consumption.
The aspirator version reduces the emission of dust into the atmosphere.

Operation
The product enters by gravity into a cylindrical rotating drum with interchangeable perforated screens. The good product passes through pre-set holes, while the large impurities come out at the end of drum. The choice of screen perforation size depends on the product, the moisture content and the type of reject to separate out.
