The grain is fed via a feed screw into the working chamber, where the product is mechanically processed by friction by a special rotor surrounded by a screen jacket. The friction intensity can be adjusted at any time either by an adjustable counterweight or by adjustable springs at the outlet of the machine. The dissolved impurities, such as the awns or impurities adhering to the surface, leave the machine through an aspirated separate outlet, separated from the product.
Due to its mode of operation, the de-awner has two positive effects on the product at the same time. It not only cleans the grain surface, but also loosens the husks of the grain by mechanical stress. This processing step improves the flow properties and at the same time contributes to an increase in the hulling degree.
The SCHULE de-awner is available in two different sizes. This allows a wide capacity range to be offered. Furthermore, these machines have a large maintenance opening, so that the screen basket and the rotor are easily accessible.
Advantages of the de-awner:
- Easy to maintain and operate
- Low-dust operation
Optionally, an aspiration channel can be connected downstream of the SCHULE de-awner. Individual husk parts that have already been loosened by the frictional treatment can thus be aspirated.
