ABSTRACT:
The invention is directed to a dispensing unit suitable to precisely dispense material in powdery and/or granular form. The dispensing device comprises an gate valve opening sealingly closed by a blend. A control unit, which is interconnected to a scaling device, controls the opening of the gate valve opening by the position of the blend. The precise amount of the material is adjusted in relation to the signal of the scaling device.
