ABSTRACT:
A vacuum drying apparatus and method to dry and cure paint is disclosed. The method provides a substantially particle free environment that shortens drying time, reduces cost and improves surface finish. The apparatus includes an enclosed drying tunnel that is maintained at a reduced pressure relative to ambient conditions. Heat lamps with the drying tunnel aid in curing and provide the desired particle free environment.
