Compact, high-capacity oven

摘要

An oven with a box-like housing for efficient use of plant floor space encases a spiral food product carrying conveyor. A process vapor is circulated within the housing by "plug fans" with the inlet drawing vapor from the central axial zone of the spiral conveyor and exhausting into plenums along the periphery of the conveyor. The plenums have nozzles oriented to project the process vapor laterally towards the conveyor.
