The L.B. Bohle BCD continuous fluid bed dryer enables the continuous drying of granules
Constant and continuous drying must be guaranteed to seamlessly connect to continuous wet granulation. With the BCD continuous fluid bed dryer, L.B. Bohle now enables the continuous drying of granules for the first time. Until now, dryers only existed on the market that did not meet the requirements of continuous drying, they only form sub-batches. However, in the BCD, L.B. Bohle implement a truly continuous process without interruptions. The results from the laboratory scale are also easily scalable to production size.
Continuously produced wet granules fall gravimetrically into the dryer without any further necessary transport steps and are then dried in a continuous process. The constant conveying of the wet granules from the dryer inlet towards its outlet is achieved by a controllable movement. This ensures gentle and very uniform drying. The movement is so gentle that there is almost no resulting back-mixing and all granules (even in different particle sizes) are dried for the same length of time. Innovative product filters guarantee service lives of days without having to interrupt the continuous granulation process. As a result, there is no loss of quality, even with finely micronized drugs.
The BCD fluid bed dryer is the ideal tool for the continuous manufacturing of high-quality products on a laboratory and production scale. The implementation of Process Analytical Technology (PAT), for example for constant in-line determination of the granule moisture content and for feedback control of the process, also ensures process and product quality. The BCD can be used within the QbCon 1 laboratory machine for throughputs of 0.25-2.5 kg/h or for production sizes up to 25 kg/h. It is available in different sizes to make production more efficient and higher quality.
