It is used to remove flour particles connected to bran. Thus, the yield of grinding system is increased. By using the plansifter around the rotor, sieving space is enlarged and the capacity is increased. There are two big control covers in the both side. Thus, controlling and shifting the sieves are facilitated. Rotor removes the bran from the flour by making touch the product entering into the machine towards the sieve and adjustable pallets. By changing the time, that the product stays in the machine, by means of pallets which are adjusted from the outside, it can increase the capacity and yield of sieving.
