Fluid Bed & Spouted Bed Dryers

Where drying, agglomeration, and coating is required for food, chemical or pharmaceutical products the combination of air and vibration is ideal. This combination produces high heat transfer efficiency and gentle handling. Special distributor plates optimise fluidising. Vibratory systems are used for operating temperatures up to 200 C while a static bed is used for temperatures up to 800 C (specialised applications).

• The process air is filtered by either felted media or polyester spun wound cartridges situated above the fluid bed. This has the advantage of no product carry-over in the outgoing air. Having the filter dust collectors above the bed ensures easy cleaning and hygienic operation.
• The process air can be re-circulated. Air/air and air/water heat exchanger options are available for very high thermal efficiencies. For drying, moistures down to 0.1% are possible, depending on the product.
• The bed can be separated into zones for high temperature, tempering and cooling as required.
• It is possible to change from a drying medium to an inert gas with a closed loop system where required.
