POWDER SYNTHESIS BY APPTEC FOR INDIVIDUAL PARTICLE DESIGN.
Advanced Pulse Powder Technology for High Performance Powder Materials.
A precursor solution is sprayed into a pulsing hot gas flow with an adjustable droplet size distribution. As a result of the defined thermal treatment, desired chemical and mineralogical reactions take place, particles are formed, and the conversion is stopped at the right moment.
The heat transfer from the gas to the particle is extremely high. Thus particle formation and phase transition run very quickly and create unique advanced crystal structures. Because of the high degree of turbulence, pulsating gas flows do not exhibit any of the temperature and velocity gradients that are typical for continuous gas flows. All particles in the pulsating gas flow are subject to the identical temperature and dwell-time treatment as the basic prerequisite for homogeneous powder materials.
APPtec is highly efficient, because of the combination of different processes in one step, e. g. drying and calcination or particle formation and coating.
FLUIDIZED BED TECHNOLOGY FOR FUNCTIONALIZATION OF GRANULES AND PELLETS BY GRANULATION AND COATING
A fluidized bed occurs when process air flowing upward lifts a layer of solid particles, fluidizing the particles. The process air is used to generate the fluidized-bed state, and also supplies the required thermal energy for the particle processes at the same time.
In addition to the thermal treatment of solid materials, fluidized-bed processes are used for drying tasks, for forming granules from powders (spray agglomeration) or liquids (spray granulation), and for the coating of particles (spray coating).
All particles are always mixed together so intensively that a uniform treatment temperature is ensured across the entire fluidized bed. This not only enables a drying process that is very easy to control, but also gentle handling of temperature-sensitive materials.
SPOUTED BED TECHNOLOGY FOR GRANULATION AND COATING - AN EFFECTIVE SOLUTION FOR SPECIAL REQUIREMENTS
The spouted-bed technology is also based on the fundamental principle of the fluidization of particles by upward-flowing process air.
The key difference is the patented design of the process air inlet as pores in combination with special flow profiles and a rapidly widening process chamber. This results in significantly higher heat and material transfer rates for the processing of sensitive products with short retention times
POWDER, GRANULES, AND PELLETS - FROM LABORATORY TO PRODUCTION SCALE.
In its own technology centers, Glatt offers you the possibility of developing processes and thereby adapting systems to your specific requirements. You can benefit from our many years of experience in process optimization.
Modern systems and our team of highly qualified; interdisciplinary process engineers are available to develop new product forms in feasibility tests or to optimize the properties and manufacturing processes of already established products in application investigations. A variety of system sizes, from laboratory models to production-scale versions, are used for these purposes.
Our fluidized-bed and spouting-bed systems operate in the development scale from 0.1 to 20 kg or produce sample amounts as pilot productions from 50 to 1,000 kg. In addition, contract manufacturing is possible on the larger scale of tons.
