Fluid Bed Machines
Used Fluid Bed Equipment
Fluid bed dryers are designed to dry small particles of product by using air or some other gas. Fluid air bed dryers hold product in a product bowl or bed. Air is drawn through the product bed because of a vacuum created in the expansion chamber above the product bed. The air passing through the product bed causes the small particles of the product to separate slightly which results in the particles of product behaving as a fluid (hence the name fluid bed dryer). As air passes around the small particles of product held in the product bed, the air draws moisture out from the particles and the air carries the moisture away as the air is discharged from the fluid bed dryer. Using a fluid bed dryer to dry product particles causes the product to remain cool because of the evaporation of moisture, so fluid bed drying can be used for heat sensitive materials.
