Cleaning technology

Air classification is from a technical perspective, the further development of winnowing.

As well as for the old technology, the basic principle, “Do not winnow in any wind“ also applies for air classification. Light wind or cleaning air leads to insufficient cleaning of the grain. Strong wind or high air flow blows the seeds away. As the good that´s being cleaned is a natural product, it has to be ensured during cleaning that the air flow is adapted to the harvest material. A cleaner setting from the last year may probably be bad for the current harvest material. Grain size and moisture content could have changed compared to the previous year and this would lead to a insufficient cleaning of the grain. A readjustment of the cleanser is necessary. 

Basis for a cleaning based on an air classifier is the so-called air speed. It gives an indication at which air speed a seed starts to hover. The speed in the classifier must in no way be exceeded, because otherwise the seed is discharged. With our classifiers, you have the world of large flow-rates at your feet. The cleaning performances range from 20 to 120 t/h. Suitable cyclones for air cleaning are also available. Steel frames according to your requirements are also supplied on request.

ZZeparator – The new grain conditioner

With our classifiers, you have the world of large flowrates at your feet.

The cleaning performances of our DLG awarded ZZeparator range from 20 to 120 t/. Suitable cyclones for air cleaning are also available. Steel frames according to your requirements are also supplied on request.

Basis for a cleaning on based of an air classifier is the so-called air speed. It gives an indication at which air speed a seed starts to hover. It is important to adjust the air speed at the cleanser, from which unwanted components start to hover but the good not yet. An adjustment is possible via an optional valve. A frequency converter can also be used.
