Operating principle

The product enters a hopper with a dosing auger and is pushed inside a fixed drum covered with an interchangeable screen.
The rotor moves the blades (variable depending on product) to a variable inclination (spiral effect), which advances the product towards the outlet.
A second version can be built featuring awners with variable inclination assembled on the rotor, which perform a centrifugal action to expel fine impurities outside the screen, with the clean product discharged at the end of the drum.

Possible solutions are:
A: Clean product sent to the end of the drum and the sub-product passes through the perforations.
B: Clean product passes through the perforations and the sub-product is discharged at the end of the drum.
