How Grain Vacs Work
Grain is carried on a cushion of air.
Grain is sucked into the grain vac and enters the main cyclone. Here the grain is separated from the air and deposited into the airlock.
The air from the large cyclone then moves to the second cyclone removing dust similar to the grain being separated from the air in the large cyclone. The cleaner air then moves up and out of the cyclone and goes through the blower.
The pressure from the bottom of the blower pushes through the airlock moving the grain out to your truck or bin
In conclusion, the grain vac not only removes dust as it moves through the grain from one spot to another, which is the main cause of health issues, but it does so in a fashion that maintains the quality and value of your crops.
