Abstract:
A thermal processing chamber for processing individual product items, said processing chamber comprising:a conveyor for conveying the product items in the chamber, said conveyer comprising: a conveyor belt forming an endless loop with a processing part and an idling part, the conveyor belt comprising a plurality of thermal conductive elements, each of the elements being adapted to obtain a first orientation in the processing part of the loop and adapted to obtain a second orientation in the idling part of the loop, the first orientation providing a substantially planar and continuous surface for supporting the product items across at least a number of the elements and wherein the second orientation of the elements provides a passage between the elements so as to allow the gas to flow between the elements; means for providing a thermal media to the chamber; and power driven means for advancing the conveyor belt, wherein thermal processing of the product items is performed by a thermal conduction between the elements and the product items.
