process to produce granules and granulate from powder and liquids based on fluid bed technology
Phosphorus recovery: Glatt Ingenieurtechnik has developed an innovative process that converts sewage sludge ash economically and without waste into fertilizer granules that can be marketed directly. (Article in German)
Mike Waskow, Process Engineer, Process Technology Food, Feed & Fine Chemicals, Glatt Ingenieurtechnik GmbH, Germany, explains how economical production of urea-based fertilizers can be achieved using fluidised bed technology. (Case study)
Fluidized bed and spouted bed are among the leading technologies when it comes to improving the physical properties of bulk solids, such as particle size distribution, bulk density, structure and morphology, in order to deliver beneficial application properties like enhanced dispersibility, solubility and flowability. The combination of processes such as drying, granulating and microencapsulating in a single step provides a cost-effective manufacturing solution.
Sustainable granulation and refining – Effective fluid bed plant design
German energy prices are among the highest in Europe. More efficient energy use pays off not only in terms of operational cost management, but also in terms of competitiveness and image. Whether in the form of spectacular architecture, as in the case of state-of-the-art, energetically self-sufficient company headquarters, or in silver-grey components for fluidized bed plants – there is always a holistic approach behind successful concepts.

Now that functional ingredients have established themselves as a dynamic market segment, the optimization of particle design has become increasingly important. The growing complexity of functional products is putting greater demands on established production processes. Fluidized bed and spouted bed processes offer manufacturers almost unlimited possibilities in terms of optimised particle design and the functionalisation of ingredients.
Product and process optimization using artificial neural networks – case study using the example of encapsulation of volatile substances by spray granulation. Food and animal nutrition products must be developed with a focus on high yields of active ingredients while maintaining low formulation costs. A continuously operated spouted bed apparatus was used to perform the process, which involves spray granulation of a liquid matrix material containing the active substance to be encapsulated.
