With our classifiers, you have the word of large flow-rates at your feet.
The cleaning performances range from 20 to 120t/h. Suitable cyclones for air cleaning are also available. Steel frames according to your requirements are also supplied on request.
During the cleaning of stored goods, it has to be ensured 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 an insufficient cleaning of the grain. A readjustment of the cleanser is necessary.
The cleaning performance of the DLG award-winning ZZeparator ranges from 20 to 120 t/h. Suitable cyclones are also available for cleaning the air. A suitable steel frame, adapted to your requirements, can also be supplied on request.
Basis for any cleaning based on an air separator is the so called hovering speed. It gives an indication at which air speed a seed starts to hover. It is important to adjust the air speed at the cleaner, 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.
The purpose of grain cleaning is to remove foreign matter such as dust, soil, weed seeds, straw, chaff and damaged grains from the grain in order to improve its quality for further processing or storage. The cleaning process is carried out using a combination of mechanical, physical and sometimes optical methods. Different machines and techniques are used depending on the pollution and requirements.
Basic processes of grain cleaning:
Pre-cleaning:
How it works: The grain falls through an air stream that separates lighter particles such as dust, chaff or husks.
Advantages:
Disadvantages:
How it works: The grain is passed through vibrating or rotating sieves. Different hole sizes in the sieves separate impurities according to size. Coarser impurities remain on the upper sieves, while smaller particles fall through.
Advantages:
Disadvantages:
How it works: Magnetic metals are separated from the grain by magnetic fields or magnetic rollers.
Advantages:
Disadvantages:
How it works: A rotating cylinder with special cutouts separates grains according to shape and size. Round foreign bodies such as weed seeds remain stuck in the recesses.
Advantages:
Disadvantages:
How it works: Cameras scan every single grain. Variations in colour, shape or size result in foreign bodies or damaged grains being sorted out by air blasts.
Advantages:
Disadvantages:
How it works: The grain is layered in a medium (e.g. water or air). Lighter particles or foreign bodies float to the top, while heavier ones sink.
