ABSTRACT:
The present invention relates to improved drying techniques which increase the capacity and efficiency of agitated pan type dryers. In particular, the present invention relates to an agitated pan type dryer apparatus and method for aggressive convective drying of hard to dry chemical compounds, such as pharmaceuticals. The aggressive drying is brought about by creating turbulence within the drying vessel during the drying cycle. Significant reductions in drying cycle times have been achieved.
