Operating principle

The product is fed by way of gravity into a feed auger to enter the hulling system, where it is shelled through a centrifugal action.
The product then passes through a perforated basket, which varies depending on the type of product being treated, before exiting the hulling unit.
The aspiration system at the exit separates the light part (gluma) from the grain, which is then sent to an oscillating separation system.
This system is designed to separate the clean product, which exits from the outer part of the plate, and the impurities, which are expelled, falling into the central part and returning to the feed auger.
