Abstract

The invention relates to a process and apparatus for desiccation in which the exterior walls of the apparatus are heated and cooled in synchronization with the interior of the apparatus to avoid temperature gradients and inconsistent desiccation of material placed within the apparatus. The apparatus wall temperature regulating means also allows for more accurate sterilization of the apparatus after the desiccation process has been completed.
