The bran brash grinding section machine is used to seperate the flow parts which were adhered to the bran.

The bran adhered to the flour comes in through the inlet and is rapidly whisked and sieved so as to seperate the bran from the flour via the pallets on the rotor. (This process is constantly repeated). Having been seperated from the flour the bran is then sent to the « bran - output » part of the machine. The sieving ratio is increased by restraining the bran flow through the rotor. An aspiration unit may be connected to the machine if desired.
