The Quatuor 2 separates the grains into four fractions, using two centrifugal sieves and airflow.

1/ The grain sample is weighed in the hopper. It is then gradually emptied.

2/ The fine particles, empty grains, dust, soil, small grains, husks, are removed to the light impurities tank using airflow and the remaining grains proceed to centrifugal sieves : 

• Broken grains and small impurities pass through the first sieve which has small perforations . This material is then weighed.
• The good grains pass through the second sieve which has larger perforations and are weighed.
• Large impurities are processed at the end of the two sieves. 


Determination of the level of impurities in grains (light impurities, broken grains, total impurities, good grains) upon delivery.


Airflow speed and rotation speed of the sieves are pre-set, based on the type of grain to be cleaned.
