ABSTRACT:
A method of transporting an article through a processing housing while minimizing the loss of a controlled atmosphere from the process housing. This method includes the steps of placing an article on a first carriage member, then vertically displacing the article from the entry level through an entry opening of entry housing to a processing level. The article is then transferred from the first carriage member to an endless conveyor for transporting, horizontally, through the process housing. The article is then transferred to a second carriage member which moves the article vertically through a exit housing to and through an exit opening near an exit level. The processed article is then removed at the exit level. The vertical distance between the process level and the entry opening and the exit opening separates the controlled atmosphere from the ambient atmosphere exterior of the housings.
