CandyWorx completed a five-pass cooling tunnel that consisted of a stainless-steel frame, insulated latching doors, a five-tier modular plastic belt with each tier having an independent conveyor system with dedicated gearmotor, and a return air plenum parallel with the conveyor ties. At each tier transition, a combination turnaround / sifter will separate and collect any sanding sugar that becomes dislodged from the gummy pieces.
