L.B. Bohle uses the Bohle Uni Cone BUC^® process to optimize fluidized bed

The patented Bohle Uni Cone BUC^® is a specially slotted air distributor plate with a conical displacement cone. This design allows for a complete fluidization of the particles. This tangential particle motion achieves a uniform film, e.g. on pellets, without any twins.

Since the fluidized particles or granules move tangentially at relatively low fluidization height, they do not require a high-volume expansion. This reduces the required installation height, saving costs and production floor space.

At least six filter elements of the BFS, that can be cleaned separately, ensure that the air flow though the product bed is uninterrupted.

Drying, granulation and coating without need for alteration

Another advantage of the tangential design in facilities from L.B. Bohle is that granulation, coating and drying can be carried out in a single system without having to reconfigure the equipment.

For the drying process, the BFS fluidized bed system can be equipped with an online moisture measurement system using NIR technology (similar to infra-red analysis). This innovation makes it possible to identify the current moisture level, precisely and reproducibly, during the granulation and drying process.
