PSC Cleaner
Separates fine, medium and large impurities in the product or calibrates using a double step system. Suitable for seed sorting.
PSC operating principle
Double step cleaning system
The uncleaned product enters by way of gravity.
The counterweight system allows the even distribution of the uncleaned product,
which is struck by an air flow that removes the lighter impurities.
The product enters the first sieve compartment, containing perforated sheet metal suited to the type of processing.
The upper sieve removes the larger impurities, the lower sieve separates the finer impurities.
The same processing steps occur in the lower compartment. Before being discharged,
the clean product is slowed using decelerators and an air flow removes the lighter impurities.
Heavier impurities are decanted and expelled by an auger, while the lighter impurities are sent to a cyclone or filter.
