Abstract

A method and plant for sanitising and drying water-containing organic material, in which finely divided material is poured into a treatment chamber that is transparent to microwave energy and heat is delivered from magnetrons (19) disposed outside the chamber (1). The material is kept at a prescribed temperature over a prescribed time period during the sanitising phase. If the temperature is required to be higher than 100 DEG C, the chamber (1) is set to a pressure that corresponds to a water boiling point that is in accord with at least the required sanitation temperature. The pressure in the chamber is lowered in the following drying phase, so as to set the water boiling point to a temperature that lies substantially beneath 100 DEG C, such as to ensure that material heated during the drying phase will be cooled by the water vapour produced and therewith minimise the risk of ignition.
