Abstract
An apparatus for transferring heat between workpieces and a container (10, 10A). The container (10, 10A) has particulate material (28) occupying a substantial portion of the volume of the container (10, 10A) and the container (10, 10A) is rotated to fluidize the particulate material which contacts the workpieces (30) for transferring heat between the container (10, 10A) and the workpieces (30). The container (10, 10A) is enclosed to provide a sealed volume within the container (10, 10A). A predetermined gas may be provided through an inlet (17, 31A) to the container (10, 10A) and gas may be exhausted from an outlet (16, 133A) from the container (10, 10A). The container may either be heated or cooled as desired.
