Abstract

The present invention is for a method and means for drying under vacuum with heating by means of microwaves. According to the invention the drying is by a combination of heating with microwaves and vacuum inside a microwave transparent receptacle or the like. The means comprises a processing chamber (1) which through a tube (3) is connected with a condensate collector and vacuum pump. A microwave generator is mounted in the space (2) below the processing chamber.
