The Semolina Purifier is used to clean and classify semolina in semolina and flour plants. The product inlet that has an adjustable amount of product flowing distributes the product uniformly on the surface of the sifter. Three frames are used for the sifting process. Thanks to the aerodynamic air duct and the air regulating valves. the equal vacuum effect is obtained on the surface of the sieves. Bran and similar products are separated from the semolina and transferred to the discharge outlet. The product (semolina) which is separated from the bran. is classified according to the size of semolina by using sifters.
