Dipl.-Ing. Katja Oppermann, Glatt Ingenieurtechnik, Weimar, will give a lecture on “Process options of fluid bed technology for value-adding product forms” at the SEPAWA Congress round about the detergents/cleansers, cosmetics and fragrance industry in Europe.
The properties of functional ingredients can be fine-tuned using fluidised bed spray granulation, agglomeration, microencapsulation and coating. At Health ingredients Europe, plant manufacturer Glatt Ingenieurtechnik will showcase a new compact spray agglomeration concept for industrial-scale continuous production.
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.
Microcapsules provide an excellent way to extend the shelf-lives of essential oils, vitamins, flavors and many other active ingredients, and protect them from external influences. A key consideration, however, is process optimization, which plays a decisive role in the quality of the ingredients and their release profiles.
Sensitive substances such as vitamins, flavors or probiotics must be well packaged to ensure that they reach their point of action safely. To ensure that they can also be released from their protective shell at the right time, fluid bed and spouted bed technologies with microencapsulation and hot melt coating offer two tailor-made finishing processes.

Technical processes improve the product properties: Feeds need enzymes that work optimally as well as being temperature-stable and storable. Two methods are particularly suitable for producing easy-to-process granules and pellets from sensitive, liquid enzyme solutions – the fluidised bed and the spouted bed methods. The plant manufacturer Glatt lngenieurtechnik is one of the world’s leading experts in this field and offers feed producers technology and plant expertise from a single source.
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.
Essential oils are volatile substances that are susceptible to oxidation and light. For protection and easier handling, as well as for better dosing and targeted release properties, these substances are increasingly offered and used by various industries in an encapsulated and often free-flowing form.
Food and feed products have to be developed with a focus on high yields of active ingredients and low formulation costs at the same time. As a typical industrial application, the encapsulation of volatile substances, e.g. flavors or PUFAs (polyunsaturated fatty acids), into dense and free-flowing granules is explained in this paper. This process improves storage stability, protects the products from oxygen and can be carried out with a continuously operating spouted bed apparatus.
