FROM POWDER MIXING TO FINISHED GRANULATE IN THE ISOLATOR Three-Tec develops high-quality volumetric and gravimetric feed units and extruders together with peripheral equipment such as spheronizers, granulators, hot die faces, conveyor belts and water baths. They impress due to their easy cleaning, simple handling and flexible adjustment to process requirements. Versatile options to integrate them into the production processes or test and laboratory applications of research and development make Three-Tec machines very popular products. Three-Tec machines are produced as custom-made designs to meet customer requirements and are largely used in the testing and laboratory sectors of the pharmaceutical and food industries. Three-Tec has now reacted to the growing demand for a production process for granulates in an isolated environ-ment and realised an isolator with integrated gravimetric feed unit, extruder, conveyor belt and granulator in accord-ance with ISO 14644-7 in collaboration with ART-Reinraumtechnik. As a result,

Highest mixing homogeneity and the hygienic design characterize the continuous mixers GCM made by Gericke. The series has now been further improved by the models type GCM ECB. With the latest design it is possible to extract the drive and the mixer housing for easy access. The mixer has 3 operation positions: - 1 Mixing position - 2 Cleaning positions The GCM 800 ECB and 1200 ECB are equipped with a cantilevered shaft and a shaft seal which can be dismantled completely in a very simple way. In this hygienic version, the parts in contact with the product are polished. The mixer has no hollow bodies where residue can build up. The experiences made with the mixers during the operation have been incorporated in the design of this latest model. For the user it means a remarkable improvement in regard of accessibility to all components and excellent cleanability of the mixer. The GCM mixer is suitable for the operation in ATEX zones. Optionally the mixer can be

Thrust blenders are the most suitable for gentle mixing of products with broad particle size distribution. For a functional-drink-application a ribbon type blender with 3000 litres useful volume was built. The blender has a single shaft. The mixing tools are ribbons, which are arranged screw-like at two circumferences. The inner ribbon with the smaller diameter promotes the product from the centre outward and the outer ribbon again inward. Pushing the ribbons through the bulk product provides the mixing. For application in the foodstuffs industry an EHEDG compliant design is used. The materials of construction were carefully selected and high quality surfaces were realized; furthermore, bolted connections were avoided as far as possible. Special attention was paid to dead-space-free constructions at the discharge, where a metallic sealing was implemented. Since the blender is wet cleaned, it is provided with particularly large openings, which improve the accessibility

The demand of toady’s factories for a modern mixer includes high capacity range, easy cleaning and small dimensions to safe space. Gericke’s GMS mixer is equipped with horizontally aligned double shaft rotors and is offering a very interesting ratio of mixer’s volume and required headroom. A 2000 l volume mixer needs less than 1.5 m headroom! The mixing tools create a fluidised bed which allows the particles to move easy and quick in the mixing chamber, without introduction of energy that would destroy the particles. Gericke therefore calls the mixer ‚Multiflux‘ mixer. The typical mixing time is below 1 minute and avoids the breakage of different ingredients like powders and agglomerates. The special shape of the mixing paddles allow the quick and efficient emptying of the mixer after a production cycle. The low number and good access to the mixing paddles makes the cleaning easy. Gericke supplies all additional equipment being necessary to fill the
