ABSTRACT:
A chiller has an insulated enclosure for maintaining the low ambient temperatures therewithin. A conveyor belt carries food products throughout the enclosure, passing through an entrance and an exit in the enclosure. The conveyor belt includes a straight-line path section and a helical path section, and is driven by a suitable drive, such as an internal rotating drum or an endless drive belt contacting a bottom tier of the conveyor helical path section. The belt includes inner and outer links interconnected by transverse rods. Upon entering a helical path section from a straight-line path section, the conveyor belt undergoes expansion only, with the inner ends of the rods undergoing only slight relative angular movement, while the outer ends of the rods are permitted an amount of relative longitudinal movement so as to allow the conveyor belt to assume a curved configuration having the desired radius of curvature for the helical path.
