Berndorf’s double belt coolers are mainly used for handling products from medium to high viscosities. Different feeding devices are available to be installed at the infeed of the machine to feed the product onto the belts. An enforced contact between two chilled surfaces ensures a faster cooling process and therefore higher capacity can be achieved, compared to the single belt coolers.
> Reduced floor space requirements thanks to the increased production rates
> Product curling is eliminated, and production rates are greatly increased since the product is put between two belts, assuring to be in belt contact both top and bottom
> Cooling can be zoned, both top and bottom, optimizing cooling performance
Single and double steel belt coolers engineered by Berndorf Band Group are used for a wide range of production processes. From cooling and crystallization to pastillation of materials like sulphur, powder paint and chemicals in the shape of flakes, pastilles, strips or sheets – all customer specifications can be fulfilled with Berndorf single or double belt cooling systems.
To solidify the molten product, nozzles spray water on the bottom side of the steel belt to guarantee uniform cooling of the product. To save the environment and to avoid a cross-contamination of the end products the systems are engineered to prevent contact between the product and the coolant.
