Vacuum drying method

摘要

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.

主权项

1. A method of drying paint applied to a painted article, comprising the steps of:
controlling a first pressure within an enclosure by drawing air from within the enclosure through a first outlet and preventing air from entering the enclosure through any opening within the enclosure such that the first pressure within the enclosure is lower than a second pressure outside the enclosure; and maintaining the first pressure within the enclosure to provide a selected drying time to dry paint applied to the painted article.
