ABSTRACT:
A conveyor assembly for use in the continuous freezing of food articles and comprising a generally coaxially arranged cylindrical core with an outer annular cylindrical shell, the annular shell defining an annular thermal treating or freezing zone. An endless spirally-arranged conveyor track creates a support platform or base for the material being treated, such as the food being frozen, and travels along a path within the annular freezing zone. The conveyor track is supported by a plurality of axially and radially spaced apart unitary support arms secured to the outer wall surface so as to support and guide the conveyor along a predetermined spiral path or course through the annular freezing zone. Each of the support brackets has a certain constant height dimension from root to tip and a generally frusto-conical width dimension tapering inwardly from the root to the tip so as to provide a stable support with a low dimensional profile. The stresses induced in the support arms upon normal loading of the track with product being treated or frozen is generally constant from root to tip.
