The pre-cleaning machine plays an essential role in the installations for seed processing as well as in cooperatives, mills, etc., which process grains and coffee.

The PRELI pre-cleaners developed by Pinhalense are sturdy machines with metallic structure. They are easy to operate and may be used for the cleaning of any type of grain by simple exchange of their screens. They present a high output in comparison with the space they use. Their uniform motion guarantees excellent cleaning and/or separation and does not transmit vibration to the floor or slab where they are installed.
