Gebrüder Lödige Maschinenbau GmbH

Lödige laboratory mixers have a drum volume of 5, 10, 20 or 50 l. They combine our usual mixing quality with an extensive range of accessories to comply with a large number of requirements.

The laboratory ploughshare mixers operate on the principle of a mechanical generated fluid bed introduced by Lödige to industrial mixing technology. Equipped with mixing elements which can be adapted to individual requirement, the mixes produced in these machines are of the highest quality. .  

The ploughshare shovels in special arrangement on a mixing shaft in a horizontal, cylindrical drum rotate closely to the wall. 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. In addition, the shape of the shovels lifts the product particles from the drum wall. 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. The so-called “mechanical” fluid bed generated in this way, whereby all the product is constantly involved in the process, ensures a maximum mixing intensity at even the highest throughputs and shortest residence times until the product is discharged out of the mixer via an outlet.

Thanks to their form adapted to individual application and the speed adjustment, Lödige ploughshare mixers can be used for a wide range of applications – for processing bulk solids (powdery, grainy, fibrous) or pumpable products.

Choppers can be additionally installed in the mixing drum to increase the turbulence in the mixing process. This also ensures the mixing of fine particles in small quantity and enables the dispersion of product agglomerations and primary particles.

The fluid bed generated mechanically achieves intensive separation of particles, especially in the upper area of the mixing drum. This optimizes the surface contact of the particles with liquids permitting lump-free mixing and homogeneous distribution.

For laboratory mixers with a volume of 50 l, the housing can be easily moved to the side permitting free access to the technical systems area.

The design of the laboratory vacuum shovel dryer DRUVATHERM® offers users a universal machine with regard to ergonomics, machine technology and process engineering options. The 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. The laboratory dryer is suitable for drying suspensions, pastes, bulk goods and powders.

The laboratory fluid bed processor is a multi-functional fluid bed processor for use in research and development and is an ideal supplement for Lödige’s high-quality laboratory product range. This machine permits different processes for process and product development:

Drying
Granulation/agglomeration
Coating (bottom spray/Wurster)
The laboratory fluid bed processor is supplied as a complete machine line, ready for connection and in a GMP compliant design. Supply and exhaust air units as well as the control system are integrated in the machine’s stainless steel housing.
