Abstract
Flotation drying apparatus for the staged (indirect) heating of solvent laden air recirculating within a drying enclosure, and a method of optimally controlling and directing solvent laden recirculation air such that condensation and sapping of solvent and various solvent-based by-products may be effectively reduced or eliminated. In addition to the reduction of condensate, a greater and more uniform mixing of the atmosphere within the drying enclosure is achieved, thereby enhancing safety and the drying process as pockets of high concentration solvent vapors are reduced. Air from outside the dryer enclosure is heated within the dryer enclosure, and is mixed with solvent-laden air. The mixed air is recirculated to the first drying zone of the dryer.
