The steps of placing material to be treated in a container, forming the material as separate bodies by placing the material in separate chambers and providing a relatively small clearance between the bodies and the chambers; forming the chambers as part of a heat-exchanger and providing a circulating treatment fluid (heating or cooling) in controlled quantities and maintaining the temperature within the chambers at a desired level; circulating the fluid in a closed circulation system and recirculating the treatment fluid repeatedly through the bodies of material and/or reversing the direction of flow of treatment fluid through the chamber.
