Abstract
A system for dying material, in which system the material to be dried is located in a drying space isolated from its surroundings, in which space drying is done by way of negative pressure and a high-frequency electromagnetic field generated by electrodes. The drying space used is a drying batch-specific film package that is substantially separate from the rest of the equipment and that can be brought to an electromagnetic field generated by external electrodes. The film package serving as the drying space comprises nozzles, and for the period of drying, the package can be connected by tubes from the nozzles to equipment for removing moisture released from the material.
