Customer directive

DTI-1520 was one of many pieces designed, manufactured, and integrated into a production line. This specific chamber was designed to cool wood siding products after the coating and curing processes. The panels and boards must be cool prior to stacking and packaging product in order to prevent products sticking together. Conveyor speeds up to 325 feet per minute were required to meet their process requirements.


Description

The DTI-1520 Cooling Chamber is comprised of four (4) ambient cooling zones and four (4) refrigerated cooling zones. Each ambient cooling zone utilizes ambient air and two fans to force air across the product in a single pass before being exhausted out of the process. The four refrigerated zones utilize two chilled water coils and a chiller to recirculate cooled air across the product. Six composite link conveyor belts convey products through all eight zones. A custom pneumatic conveyor tensioner ensures proper tension for operation even as the conveyor thermally expands and contracts and mechanically wears and stretches. A limit switch will stop the conveyor if the tensioner ever reaches the end of its travel. Plenum nozzles above the product provide top down air flow to heat the product as it is conveyed. Additionally, the system is elevated above finished floor to maintain line height through multiple process equipment.
