ABSTRACT:
An apparatus for drying gel slabs supplies heat to a horizontal gel slab from a heating plate above the slab, while drawing a vacuum beneath. The heating plate is weighted and has a flat lower surface at least coextensive with the gel slab. The slab itself is placed on a porous support pad in a vacuum chamber enclosed at the top with a flexible cover which clings to the gel and seals to the perimeter of the chamber when a vacuum is applied from below. The heating plate rests on top of the cover under gravitational force, providing even heating across the entire expanse of the gel slab and for the entire duration of the drying process, resulting in a continuous and uniform vapor flow downward from the gel slab, a minimization of internal stresses, and reduced susceptibility of the gel to cracking.
