ABSTRACT:
A thermal treatment system includes thermally insulated housing structure in which conditioning plenum structure and distribution plenum structure are disposed. The distribution plenum is disposed adjacent a treatment zone that extends through the housing, and the side of the distribution plenum adjacent the treatment zone defines an open port region that corresponds in dimension to the length and width of the treatment zone. Seal flange structure extends along the edges of the open port region. Conveyer structure for supporting product to be thermally treated is disposed in the treatment zone in juxtaposition to the open port region of the distribution plenum. A series of sealed chamber units, each of which includes an array of nozzle tubes that provide an array of spaced parallel flow passages through the sealed chamber, close the open port region so that the series of sealed chamber units defines a wall of the distribution plenum adjacent the treatment zone. Conditioned gas from the conditioning plenum is flowed into the distribution plenum for discharge with substantial velocity toward the conveyer through the nozzle tubes of the sealed chamber units for thermal treatment of products being transported by the conveyer structure through the treatment zone. Releasable clamp structure that seats the sealed chamber units on the distribution plenum flange surfaces provides seals between the sealed chamber units and the distribution plenum seal flanges and facilitates removal and cleaning of the chamber units.
