The temperature of the commodity is held at this temperature until the pest is killed. The commodity is loaded into the treatment chamber in bins onto a low friction conveyor track system which transports the bins from one end of the chamber to the other. The commodities are treated while they are inside of the treatment chamber. After treatment of the commodities, the bins are unloaded using the low friction conveyor track system out of the opposite end of the treatment chamber. The chamber includes a fan/heat exchanger located inside the treatment chamber and positioned under the commodity bins. The space directly above the fan/heat exchanger is left unobstructe…
