Lödige Process Technology, Paderborn, Germany, has built the smallest machine in its history in order to meet the highly specialised demands of the high-containment sector: The new type L 1 .loughshare® laboratory mixer supplements the L series and has a drum volume of just one litre.

An enquiry by an existing customer led to this development. The company in question was looking for a process engineering solution for exceptionally challenging dry mixtures for its development laboratory. As powdered substances such as these can be highly sensitive, extremely expensive or perhaps even hazardous to health and the environment, the only suitable solution was a contained process in a gas-tight container, widely known as a ‘glovebox’, meaning that the mixer can only be operated and serviced within a glass safety housing using integrated gloves.

All components are easy to remove, particularly wear parts, which must be inserted into the glovebox through an airlock. They can be easily replaced and reinstalled in this manner. This laboratory mixer is a special addition to the L series, which is Lödige’s lab range for small batches. These machines are designed for development and small batch production and are available in several sizes with drum volumes generally ranging from 5 to 50 litres. The L series laboratory mixers cover a wide range of applications in product and process development. In particular, they permit processing of powdered, grainy and fibrous components, addition of liquids for moistening, granulation and coating, processing of fragile substances without destroying their structure and mixing in of greases and similar substances.

Like other Ploughshare batch mixers, the laboratory mixers use the blending and fluidisation process introduced to industrial mixing systems by Lödige. This process involves the generation of a fluidised bed. Equipped with mixing tools specifically adapted to the respective task, these mixers are designed to achieve a high quality, which is reproducible at any time. www.loedige.de
