The MAROT Model A vacuum is used to remove light impurities from grains and, at the same time, separate the vacuumed heavy material from light dust. The equipment can be used individually or in conjunction with a pre-cleaner or rotary cleaner.
The raw grain enters the machine through the feed hopper and is distributed in a flow curtain by means of an adjustable baffle. Air is sucked through the grains carrying light impurities. A feed cylinder assists regular grain flow. In the suction chamber, the heavier particles leave the air flow and are removed by a worm, and the lighter ones are sucked in through the exhaust air.
These compact pre-cleaners are simple to integrate into a cleaning system with capacities from 7 to 50 t/h.
