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. |

1. A conveyor oven, comprising:
an insulated enclosure defining an interior space; a conveyor belt traversing the interior space of the conveyor oven; a heating element adapted to heat the interior space of the conveyor oven; an air mover positioned and adapted to move air into and along the interior space; and a plurality of pairs of adjustable baffle plate assemblies, one baffle plate assembly of each pair of baffle plate assemblies positioned above the conveyor belt and the other baffle plate assembly of the respective pair of baffle plate assemblies positioned below the conveyor belt, each of the adjustable baffle plate assemblies including a fixed portion that makes a connection with a top or bottom wall of the interior space, a rotational joint connected to the fixed portion, and a movable portion mounted for rotation about the rotational joint, the movable portion having sufficient dimension and extent to influence airflow within the insulated enclosure, wherein the conveyor oven further comprises a plurality of idler rollers mounted for rotation along the length of the conveyor oven, the idler rollers being positioned to support the conveyor belt, each end of each of the idler rollers penetrating side walls of the insulated enclosure via a penetration support mechanism including a first insulated block positioned behind and proximate to an interior side wall of the conveyor oven, the first insulated block defining an oblong slot through which one of the ends of one of the idler rollers passes, a second insulated block positioned behind the first insulated block proximate to an exterior side wall of the conveyor oven, the second insulating block being narrower than the first insulated block, but having sufficient width to cover the oblong slot, and being narrower than a channel or space in which it is installed, the second insulated block being free to move relative to the first insulated block within the space which it is installed, and a bushing or bearing in the second insulated block that receives and supports the idler roller. |
