Lödige DRUVATHERM® reactors are batch reactors. Rotating mixing elements adapted to the specific process, installed in a cylindrical drum equipped with a temperature control jacket, create a three-dimensional product movement. The resulting contact frequency of the reacting agents with each other leads to a more effective conversion with a higher yield. The mixing elements ensure high contact frequency of the reacting agents with each other and intense contact of the reacting agents with the heated or cooled vessel wall. This makes reactions in homogeneous and heterogeneous phases possible in practically all combinations (solid/liquid/gaseous). The production consistency can be anywhere along the spectrum of liquid to pasty to lumpy to pourable. High-speed rotating choppers installed on the side of the machine drum perform additional mixing work to distribute the reacting agents.

The high-shear mixer is a system for mixing, granulation of pharmaceutical powders and granulated products. Moreover, it is suitable for a wide range of cosmetics and food products. A three-bladed mixing tool rotates in a vertical, cylindrical mixing vessel close to the wall and to the bottom of the vessel. The shape and peripheral speed of the mixing tool create a vortex-like circulation of the mix. A separately driven chopper is used for breaking up agglomerated products as well as for moistening and granulation. Liquid addition is either gravimetric or uses a pump to add liquid directly to the effective range of the chopper, so that the best possible distribution is ensured. The optional wet sieve on the discharge ensures a completely homogeneous distribution of the granulate size. The PC/PLC-based control system to be compliant with CFR-21 Part 11. The updated user interface permits intuitive machine operation in service and automatic mode for production and cleaning operation.

Lödige shovel dryers are batch vacuum dryers. The mixing elements are frequency-controlled for ideal adaptation to the process. Special rotating mixing elements, installed in a cylindrical drum equipped with a temperature control jacket, create a three-dimensional product movement . The resulting contact frequency of the particles with the heat exchange surface leads to incredibly short drying times. The intelligent product movement ensures intense contact of individual product particles with the heated container wall while also providing very gentle product treatment. The chopper rotating at high speeds is used to disperse the product during transition between phases. Product surfaces are opened up during this process. This leads to a significant increase in drying capacity and prevents moisture and temperature gradients. Fine particles pulled along by solvent vapours are separated in the filter and returned to the product bed through pneumatic filter cleaning.

The continuous ploughshare mixer uses the mixing and fluid process introduced to mixing technology by Lödige. The ploughshare shovels in special arrangement on a mixing shaft in a horizontal, cylindrical drum rotate. Their peripheral speed and geometric form are coordinated in such a way that the mix is moved out of the product bed against the centrifugal force and in axial direction at the same time. The mixing elements having a defined shape and a special arrangement on the shaft, they ensure not only a reliable product conveyance but also a sufficient back-mixing of the product. All the product is constantly involved in the process, ensures a maximum mixing intensity at highest throughputs and shortest residence times until the product is discharged out of the mixer via an outlet. The continuous process can be run at filling levels between 20 % and 50 % without influencing the mixing quality. Choppers can be additionally installed in the mixing drum.
