ABSTRACT:
A freezing tunnel includes a longitudinally extending housing defining a cooling cavity containing a cooling atmosphere which progresses from one end of the tunnel to the other end. An endless mesh belt extends through the housing for carrying articles to be frozen. A shroud is located within the housing and extends transversely across the belt and terminating in edges which define an opening. The shroud defines an inner region and an outer region between the inner region and the housing and includes first and second longitudinally spaced shroud portions, each having respective apertures for allowing fluid communication between the inner and outer regions. Electrically driven fans direct the cooling atmosphere through the respective apertures and the opening and past the articles to be frozen.
