Static fluid bed dryers

In addition to spray dryers, we at Dutch Drying Systems also offer static fluid bed dryers. It is obvious that we tailor them to the requirements of the customer.

In a static fluid bed dryer, the products that need to be processed float on a cushion of air or gas. The process air is supplied to the bed by a perforated distribution plate. Then the air flows through the bed of solids at sufficient speed to support the weight of particles in a fluidized state.

Within the fluid bed, bubbles form that burst: this promotes an intense movement of particles. In this state, the solids behave like free-flowing boiling liquid. Very high heating and mass transfer rates are obtained through the close contact between individual particles and the fluidization gas.
