Device and method for evaporating an organic powder
The invention relates to a device and a method for evaporating a non-gaseous starting material, in which method the starting material is introduced into an evaporation chamber (3) of an evaporator (1); an evaporation element (4) of the evaporator (1) supplies heat to the starting material such that...

| description | The invention relates to a device and a method for evaporating a non-gaseous starting material, in which method the starting material is introduced into an evaporation chamber (3) of an evaporator (1); an evaporation element (4) of the evaporator (1) supplies heat to the starting material such that it is evaporated to create a vapour; the vapour is transported by means of a conveying gas flow, which is fed through a gas supply line (9) into the evaporation chamber (3) and the mass flow of which is controlled by a first mass flow controller (10), through a conveying channel (7) and past a sensor (8), which measures the concentration or the partial pressure of the vapour in the gas flow flowing through the conveying channel (7); and the mass flow of the vapour through the conveying channel (7) is controlled by varying the conveying gas flow with respect to a setpoint value. In order to keep the vapour flow delivered by the device largely constant over time, a compensating gas flow is fed into the conveying chan |
