This machine are used for separating of lightweight products as like bran/flour from the bulgur after the peeling, grinding and polishing processes of the bulgur. This machine consists of air duct and sieve system. The air duct system is separated the products in the air with floating process by means of the laminar flow of the air. The sieve system was designed with a certain slope is supported by vibro-motors and it has a vibration adjustment mechanism to make a sensitive separation calibration. The product flow and cleaning accuracy can be easily monitored by means of the sight glasses. Bran receiver concentrators provide a cleaner and hygienic production than the peer systems because they work in closed systems. This system can also be used for cleaning process of different products by changing the sieve sizes and terminal speed.
