Pirouette® Cross-Flow Dryer

The Pirouette® cross-flow dryer concept is based on first-in/first-out principle. There is full separation of batches/layers and a vertical airflow, in opposite direction to the product flow.

Function

The product lies on perforated trays. The height of the product layers is determined by the patented spreader-device, electrically driven and controlled by PLC programming. Our spreader action is unique and guarantees a regular surface over the whole bed, creating a uniform depth of product with no ‘dead zones’ in the trays. The first deck works as a ‘flash off’, then discharges the product to the next deck and the procedure is repeated. Air temperature and air humidity are controlled and monitored by accurate instruments. This ensures a very gentle and even drying process. The flow of the drying air is mainly controlled by patented design of the trays, which makes it less dependent on the height of the product layers. Having multiple decks makes it possible to create adapted atmospheres, according the state of the product (temperature, humidity). Contamination free, multi-deck extraction. It is a controlled drying process with minimal variation in moisture content.
