In flour mills, the blower is used for the transportation of wheat and finished products (wheat, bran etc.) and for the cleaning of jet filter bags. In transportation systems, it provides hygenic horizontal and vertical transportation thanks to the high pressure it creates. Since there are no surfaces for deposit formation; for the transportation of flour and bran, the use of blower transportation system is more hygenic then the use of elevators and screw conveyors. For the cleaning of jet filter bags, the blower provides the high pressure air for the shaking of the filter bags.
