Patent attributes
A conveyor oven is described. The conveyor oven includes a frame made of load-bearing structural members. The conveyor oven has a modular construction, with the structural members defining a rectangular prism. Blocks of insulation are placed in the frame openings, and a flexible insulating material, such as a multi-layer insulating textile, is used to cover joints between adjacent modules. Along the length of the conveyor oven, idler rollers that support the conveyor belt have ends that penetrate the sides of the oven and are supported such that the rollers can shift as the oven expands and contracts without creating openings for heat or air leakage. Air flow within the oven is managed using sets of adjustable baffle plates above and below the conveyor belt.
