Abstract: A processing facility, for subjecting products to process conditions for lengths of time and having a processing chamber equipped for establishing a predetermined condition within and throughout the chamber, a pair of continuous flexible conveyor elements, extending through the chamber along a generally zig-zag pathway, rotatable bearing members for supporting the flexible elements in predetermined lengths, spaced one above the other, and spaced apart from one another, the flexible elements being extended around respective bearing members, in a generally zig-zag fashion, product supports extending between the flexible elements, attachments at each end of the products supports for attachment to respective flexible elements, so that the product supports are freely swingably supported between the flexible elements, and the rotatable bearing members being spaced apart on opposite sides of the chamber a distance greater than the length of the product supports so that the product supports may freely pass between th
