Fluidized bed dryer Conti FB

The continuous fluidised bed technology offers ideal possibilities for a targeted modification or customised optimisation of the product properties of bulk goods. In continuous fluidised bed plants, the processes are fully automatic. They are reproducible at any time and ensure a high product quality. Unlike batch plants, the product passes through several zones in one apparatus, in which run various processes such as agglomeration, granulation and drying take place simultaneously. The continuous fluidised bed plants are especially used where high efficiency is required by reducing the operating and production costs. Depending on the size of the plant, e.g. 200, 2.000 or more kilograms per hour pass through the entire process with one or more functionalities such as drying, agglomeration, spray granulation, coating or micro-encapsulation. Optimum Heat and Mass Transfer In our continuous fluidised bed system, the input product is proportioned into the apparatus on the front side e.g. via a differential proportioning weigher with downstream double flap system. From below, air is supplied through an air distribution plate. This fluidisation air turns the product into an expanded fluidised bed. The forced convection in the fluidised bed leads to an optimum heat and mass transfer, which enables highly efficient drying processes. In an apparatus with zone division, the air quantity and the temperature of each section can be set individually. At the end of the apparatus, the product is continuously discharged and supplied to downstream process steps. The process air leaves through an exhaust air hood.
