ABSTRACT:
Solvent-treated objects are dried in a drying chamber having a drying zone and at least one transfer zone for introducing into and/or removal from the drying zone of the object. The drying zone is created by recirculating drying air at high air flow rate by selectively sucking air from and blowing air into the drying zone and by removing recirculated solvent-carrying air from the drying zone by suction to provide a negative pressure in the drying chamber with greatest negative pressure in the drying chamber in the drying zone. Removed drying air is preferably passed through a solvent recovery carbon filter.
