Abstract

Impingement heating or cooling apparatus that employs an axial flow fan, a plenum, collector and a columnating assembly for directing jets of a temperature controlled gas against the surface of a food product. Means for contacting a first layer of food products with impinging jets of a temperature controlled gas and for simultaneously contacting a second layer of food products with an alternating, convective flow of a temperature controlled gas is also provided.
