The air quantity of this machine, which works with air flow, is adjusted according to the type of wheat used, and it works optimally. There are two models with and without vibration motor. The vibration motor increases the performance by ensuring that the product is distributed homogeneously when it comes from a single point. In the air ducts used after the separator, the vibration motor is not used because the product is homogeneous. Since it does not produce negative air pressure, it must be connected to the factory's aspiration system.
