Double-belt has many advantages: compact design, small land occupation, high cooling efficiency, large output. In some application fields, the cooling efficiency of double-belt is better and faster than single belt’ s.

Material is transported to the upper surface of lower belt which sends products to cooling area. Upper belt’ s pressure makes products touch with two cooling surfaces of upper and lower belts, which rapidly realizes the cooling effect.

Products like wax and resin are easy to curve on single belt, but double-belt can avoid this phenomenon. Also double-belt can cool thicker products and keep consistent temperature at the material discharging mouth.
