Abstract
Apparatus adapted to deliver a temperature-controlled gas from a common plenum to at least two thermal treatment zones is provided. The subject apparatus is adapted to direct columnated jets of a temperature-controlled gas so as to impinge on at least one surface of food products passing through such zones, and is further adapted to convey food products through such zones in multiple passes in which the food products are subjected to different thermal energy transfer rates in at least two of such zones.
