Reliably operating spray nozzles and a flawless spray pattern are indispensable in fluid bed processes. A new spray nozzle safety mechanism from Glatt Ingenieurtechnik, specially developed for products relevant to explosion protection, enables the spray nozzle to be safely dismantled during operation.

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.
Application-specific product formulations require that the organisms are kept in a state capable of multiplying from the time of their production through storage to transport to the place of release. Fluidized bed and spouted bed processes offer a very high potential for different heat and mass transfer processes due to their unique fluid mechanical and thermodynamic properties. The drying and stabilization of microorganisms for food and nutraceuticals is one of many examples that illustrate the close interplay between formulation, process engineering and plant engineering.
Product safety for food, biotechnology or similar applications: Fluid bed and spouted bed systems of various designs and sizes are used for granulation, agglomeration, coating or heat transfer processes, such as drying or cooling, in various branches of industry. In addition to product properties, production and product safety are also essential elements in establishing such processes. In particular, the respective hygienic conditions require compliance with special planning and design principles in plant conception. (German article)
Fluid bed and spouted bed systems of various designs and sizes are used for granulation, agglomeration, coating and heat transfer processes in many branches of industry. Product safety is the top priority when establishing such processes. To ensure compliance with the relevant hygiene conditions, special planning and design principles are taken into account in the plant concept. These include steel construction, insulation, operating panels and wall penetrations. (German article)
For the production of granulates from solid and/or liquid raw materials and the coating of particles, fluid bed plants offer many possibilities for influencing the granulate properties. The process chamber of fluid bed systems must be permeable to the process gas at the bottom and at the top. It is usually bounded at the bottom by an inflow floor and at the top by a filter. The filter is thus of decisive importance for the process. (German article)
At the end of 2009, one of the world’s largest spouted bed systems for granulation started at the Dresden-based contract manufacturer IPC. A ProCell 250 from Glatt Ingenieurtechnik GmbH enables a so far unreached flexibility for agglomeration and spray granulation processes. Liquid and/or solid raw materials can be processed to granulates and pellets or existing particles can be coated. Batch or continuous operation is possible.
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.
