press release

At Achema 2012 in Frankfurt/Main, Germany, Bosch Packaging Technology presents two complete modular plants for laboratory usage at its booth (C70 and C72) in hall 3.1. The laboratory plants Solidlab 1 and 2 have been jointly developed by process technology specialists Hüttlin and Manesty. Both versions combine three process modules in one single machine: powder mixing, granulating and coating of pharmaceutical pellets and tablets. “Our recent developments Solidlab 1 and 2 are very cost- and space-efficient,” explained Uwe Schmidt, Director of Engineering at Hüttlin in Schopfheim, Germany. “By using a common base assembly, the different process modules can be integrated in the same machine.”

Common development by two specialists
Bosch enhanced its process technology portfolio with the acquisition of Hüttlin GmbH and Manesty (now Bosch Packaging Technology Ltd.) last year. The two specialists joined their expertise in the development of Solidlab 1 and 2. The concept of the laboratory machines is based on the effective use of peripheral equipment, control systems and data acquisition in combination with the intelligent integration of high quality process modules. The single modules are structured as they are in complete production plants. Solidlab 1 handles batches from 0.05 to two kilograms. Based on the same construction principle, Solidlab 2 processes volumes from 0.5 to 12 kilograms.

The module for powder mixing consists of a square container which is eccentrically mounted in an open drum. Using this mixing principle, high mixing qualities can be obtained even for small amounts. The fluidized bed enables an even distribution of the supply air and torodial material movement through a special disk jet distributing tray. A bottom sprayer system with its robust three-component nozzle ensures optimum coatings. The drum-shaped coater has a fully perforated drum with a high amount of perforated surface, a guided air stream going straight through the tablet bed, as well as a special exhaust air plenum chamber. The nozzle system can be set up to accommodate any batch size and warrants the consistent application of the spraying liquid. This results in short processing times, as well as high yields and quality.

Easy scale-up to production conditions
“Each of the three modules uses the same base assembly which includes all peripheral equipment, such as the infeed and exhaust air conditioning, the complete sensor system and especially the control system,” underlined Schmidt. The device that consists of module and base assembly is equipped with a 10 inch touch screen interface, running the newest generation of Provicon Mod software. A variety of options are available: fully automated formulations, data recording, CFR 21 compatibility, trend depiction, and data export via network or USB stick. The processes of Solidlab can easily be transferred to larger production plants via scale-up. New formulations can be developed and tested in the laboratory, and can be easily transferred to production scale in a next step.
