The Bella Series 543 mixer/dryer/cooler offers a new method for drying or cooling powders, granulates, and filter cakes. The Bella dryer can be used for drying, mixing, spraying, agglomerating, and cooling in the same unit without additional equipment or costs. Operation is extremely efficient because air flows around material while it is suspended in the weightless zone of the mixer. This maximizes the total surface that is exposed to the air, increasing the desired effect. The drying process will go through an adiabatic evaporation with thermal efficiency at about 80 percent. Only small air volumes are required compared with other fluidizing dryers. Benefits include: better air distribution, which increases drying/cooling efficiency; homogeneous mixing during the drying/cooling process; low air volume reduces filter requirements, rotating paddles prevent material lumping and air channels; increased air contact creates better thermal efficiency; random material/air movement reduces drying/cooling time; gentle paddle motion creates low shear and low energy usage due to high thermal efficiency.
