Abstract

Apparatus suitable for the heat treatment of a bulk feedstock comprises a receptacle (101) suitable for receiving a bed of feedstock, an inlet (111) through which microwaves may pass to enter the receptacle (101), causing the feedstock bed to heat up due to volumetric heating effects to release inbound moisture to regions within the bed, a stock of reusable agitator elements (200) mixed within the bed of feedstock, the elements preferentially absorbing at least some of the microwave energy thereby heating up to cause additional heating of the moisture or vapour or gas released from the feedstock, and a vibratory means (110) which is operable to cause the receptacle to vibrate and agitate the feedstock and agitator elements and the released liquid or vapour in the receptacle so as to produce a fluidised bed of feedstock, in which the agitator elements are shaped so as to assist in the formation and collapse of microvoids within the bed to drive released moisture of vapour out of the bed.
