The new generation of fluid bed systems offers many exciting, new concepts. The Bohle BFS is suitable for drying, granulation, layering and pellet/particle coating without any optional modifications. This new processing design is much more robust than traditional Wurster technology.
Due to the shift from top-spray technology to tangential-spray technology, the latest design of the BFS is extremely compact and reduced in overall height. Furthermore, a self-supporting structure without additional side bearings is incorporated to enable simple access and exterior cleaning. Spray nozzles are arranged tangential to the product bed and can be exchanged during the process from the outside. The BFS includes large sight glass ports without intrusive fasteners for easy cleaning and unobstructed product visibility. The product bowl is equipped with an integrated bottom discharge valve. Using vacuum transfer, raw materials can be introduced into the bowl through the discharge valve. The standard BFS comes with a hinged process bowl which can be swiveled sideways, eliminating the need to disconnect media supply lines before opening the system. This feature permits effortless interior access for maintenance and inspection procedures. The new BFS 30 is currently available in the L.B. Bohle Service Center in Ennigerloh, Germany, and can be reserved for individual trials.
