Device for solvent extraction in microwave field, comprises flow detector arranged downstream of removal opening to reduce power of microwave generator when air stream lying below prescribed boundary value is detected

摘要

A device for solvent extraction in the microwave field comprises a flow detector (28) arranged downstream of a removal opening (24) to reduce the power of a microwave generator (12) when an air stream lying below a prescribed boundary value is detected. The boundary value is selected so that the formation of an explosive solvent/air mixture is prevented in the microwave chamber (14).
