BRC 100 with Bohle genes

Continuous production, easy handling and small footprint

Ennigerloh, June 2012 – Insiders quickly recognise Machines from L. B. Bohle: easy handling, continuous production and small footprint are the typical features of the products from Ennigerloh. With the BRC 100, a drying granulator is set to celebrate its world premiere at the ACHEMA 2012 in Frankfurt, revealing its typical Bohle genes.

In the roller compactor powders are processed into fluid granules. The objective in the pharmaceutical industry is to process a granule with defined density or porosity for immediate tabeletting thereafter. The powder is fed via a dosing unit, compacted between two rollers with gaps ranging from 1 to 6 mm and discharged as scabs. The impact on the rollers, as well as the gap width are monitored sensorially and integrated into a control circuit to ensure continuous optimum process parameters.

The chopper unit below the compact rollers processes scabs into granules. The unit is equipped with a conical sieve with exchangeable sieve units for processing different particle sizes.

“While developing the project, we questioned customers very precisely about the ways to meet their requirements”, said Thorsten Wesselmann, engineer and Head of Mechanical Construction at L. B. Bohle. “Easy control, easy cleaning and less edges, screws and angles”, were consistently requested. Especially the control of the pressing force via standard hydraulic systems constitutes a great problem, when the process is aimed to comply with “hygienic design”. “However with our electro-mechanical batch we were able to solve this problem”, explained Wesselmann. With the Bohle BRC 100, frequent axis adjustment as with traditional roller compactors is a thing of the past. Thanks to a special bearing method, the axes are mechanically stable so that elastic deformation is prevented. This eliminates the need for complete axes control! Moreover, the BRC 100 is low maintenance. Even when cleaning is required, only four screws must be removed. Furthermore, Bohle engineers reduced the overall height by 20 percent.

“We only needed one year from the initial idea to the ready machine”, said Lorenz Bohle in praise of his team. “We are now able to offer our customers machines and processes for all stages of the granulation process with our new BRC 100 – continuously, and with the proven Bohle quality”.

The advantages of the new Bohle - BRC 100

- Minimal material loss due to precise control of the compression force with an innovative electromechanical roller drive - Constant ribbon properties assured with sensitive gap width control - Easy handling and short mounting procedures - Hygienic design and effective cleaning by integrated WIP nozzles - Versatile and gentle particle size adjustment with integrated Bohle Turbo Sieve (BTS 200) PAT tool integration possible
