One feature of the Heinen fluidized-bed (FB) systems is the high-performance filter cartridges integrated in the dryer’s hood (photo), separating and recycling the fine dust particles that are produced during the process. No material is lost with the exhaust air, nor pollutes the ambient air. The filters are directly cleaned via cleaning nozzles integrated in the dryer’s hood. The filter types (stainless steel, PTFE or PP) are selected according to the process (drying, cooling, agglomeration and so on) and product (coarse and fine-grained powders; granules, pellets or extrudates; suspensions, solutions or slurries). — Heinen Drying GmbH, Varel, Germany
