The coaters series type LC were specifically developed for coating tablets. With our coater range, Loedige is one off the technological market leader. The maximised tablet bed surface in the Lödige coater and the maximum number of spray nozzles mean that extremely high liquid volumes can be applied with extremely high air supply volumes within a very short time. The newly designed, particularly low-turbulence air routing ensures a highly efficient and gentle use of dryer air. These features ensure a reliable coating process and short process times. Moreover, the low-turbulence air routing prevents contamination from the very start, thereby reducing the cleaning workload. Modern sensors permit optimisation of the spraying and drying process. Simple yet secure nozzle arm adjustment makes for easier handling.

The Lödige laboratory tablet coater has a modular design, so that integration of any components is customised according to the customer’s specific requirements. A dividable drum and a dividable nozzle arm allow processing of even very small volumes (0.6 l). The coater and the optionally available liquid supply station consist of Corian®, a highly resistant, light-weight, FDA-approved material, which is crucial for the particularly functional and modern design of the laboratory coater system. The laboratory coater is not just a “laboratory machine”, but a full coating system, in which process conditions comparable to those of Lödige production coaters are generated. The mobile laboratory coater incl. the drum for the tablets and drawer for the nozzle arm and tool form the base unit. In addition, the following equally mobile modules are available: — Air supply unit — Exhaust air unit — Liquid supply station (optional)

The laboratory vacuum shovel dryer DRUVATHERM® is a system provides reliable scale-up to production scales in the context of product and process development and can likewise be used for small batch production too. The Lödige laboratory vacuum shovel dryer DRUVATHERM® is a horizontal, batch vacuum dryer with a frequency-controlled mixing tool. This mixer consisting of mixing elements adapted to the process and arranged on a shaft according to a specific system - is installed in a cylindrical mixing drum equipped with a temperature control jacket. Rotation of the mixing unit generates a three-dimensional product movement, in which all of the product is constantly in motion. The contact frequency of particles with the heat exchange surface leads to shorter drying times. The chopper rotating at high speeds fitted to the side of the mixing drum is used to disperse the product . This leads to a significant increase in drying capacity and prevents moisture and temperature gradients.

Lödige has years of expertise in continuous granulation. Nowadays, continuous ringlayer mixers are established systems for continuous granulation in many industries. However, until now the Lödige product range was missing a suitable dryer. The continuous fluid bed dryer closes this gap. Together with the ringlayer mixer CoriMix® and the customer-specific dosing system, this dryer provides a complete continuous granulation line: GRANUCON®. Dryer operation is based on the fluid bed process. A general disadvantage of continuous fluid beds is the wide retention time distribution within the machine. Lödige’s developers have looked into this problem and have found a solution: integrating a screw in the fluid bed dryer. This has a limiting effect on the retention time distribution. — Exchangeable floor — Quick screw removal — Integrated WIP cleaning — Individual purging of filter elements

The granulation dryer is designed for continuous operation. A unique property of this dryer is its combination of convection and contact drying. Adaptation of the retention time to the specific process ensures that products are dried at low temperatures. At the same time, excellent granulation of the final product can be achieved. This intense mixing effect separates the particles in the fluid bed, thereby creating a large product surface and preventing the generation of temperature and moisture gradients in the product bed. This leads to a significant increase in the heat exchange via the heated drum walls. The product behaviour during drying is affected by the mixing tool geometry and choppers can be activated as an option; these can be used to control the average product retention time and the retention time distribution. It is therefore possible to achieve a defined grain size distribution during granulation processes
