Fluidized bed dryer

cleaningwith heat exchanger

The fluidization is a state of dynamic balance of a divided solid in an ascending moving gas. It confers hydraulic properties to solids (angle of repose equal to zero, easy spreading, total filling of a receiver in which the product is fluidized). Such method of bringing in contact a solid with a gas, allows high mass and heat transfers. Mechanical energy transferred by gas to the particles is low enough to prevent attrition. Crystals for instance will remain bright and will keep sharp edges. ADVANTAGES OF THIS TECHNOLOGY Controlled residence time allowing uniform treatment Low attrition of particles High thermal efficiency Preservation of physical and biological properties of fragile products Simple and robust equipment (no mechanical device) Low maintenance Easy cleaning Multiple processing in one single equipment Possibility to process under controlled atmosphere in a closed loop (i.e. nitrogen, hydrogen, etc.) Adjustable fines removal ratio
