Fluidized bed technology for granular, crystalline and powdery materials. A stream of hot air suspends the particles, giving uniform, gentle drying with precise moisture control in batch or continuous configurations for pharma and food.
The Gausin Fluidized Bed Dryer (FBD) dries wet granules and powders by passing hot air upward through a perforated distributor plate, fluidizing the bed so each particle is surrounded by drying air. This delivers very uniform heat and mass transfer.
Because every particle is gently suspended and individually dried, the FBD avoids local overheating and produces a free-flowing product with tight, repeatable moisture. It is the standard dryer for dairy, many food and chemical powders.
Gausin offers continuous fluid bed dryers (Vibro or static) for high-throughput dairy, food, salt and chemical duties, with GMP execution, explosion safety and CIP options.
