Grain cleaning

The basis for grain processing in the mill is thorough and gentle cleaning of the raw material. To separate contaminants and foreign substances, such as stones and weed seeds, different machines are used that supplement each other perfectly and thus ensure a high level of cleaning efficiency.

Grain classification through rotation machine

In the cleaning process the indent cylinder primarily separates weed seeds, foreign grain and long grain portions. Through rotation, the indent cylinder classifies grain by length and thus differentiates between cut and uncut grains or between husked and unhusked oats.

The work cylinder of the indent cylinder consists of two half-shells that have a variety of tear-drop shaped bays. The product is separated in these dents. A high level of separation is achieved thanks to the high-quality craftsmanship with precisely punched dent edges. In a trough within the indent cylinder all small parts are lifted and conveyed out of the machine with the aid of a screw conveyor.

The incline of the troughs, as well as the pressing of the indent cylinder, can be adjusted individually so that optimal results are achieved for the respective product.
