technology to produce granules and pellets from powder and liquids
High dust content and bad flowability often cause problems during the filling, dosing or application of powdery substances. This situation can be improved considerably through agglomeration using the fluid bed technology. Glatt Ingenieurtechnik designs und constructs these kind of fluid bed plants for various applications. (German article)
Flowability, dustlessness and easy dosing — these are some of the plus points of granulates produced by fluidized or spouted bed technology. The product design can be specifically influenced by process engineering. (German article)
Glatt Ingenieurtechnik GmbH has completed a fluid bed plant in Scandinavia for the continuous coating of additives with a capacity of several tons per hour. We spoke to Christian Heiermann, Engineering Sales Manager in the Food, Feed & Fine Chemicals Division, about this large-scale plant and about Glatt’s role as an engineering partner in a wide range of industrial sectors.

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)
Glatt’s Technology Center in Weimar stands for innovative technologies for the production of granules and pellets from powders and/or solid-containing liquids. In the last 12 months alone, more than 120 customers from 17 countries used our advanced equipment to develop new product forms by feasibility studies or to optimize the properties of already established products for their production processes. Apparatuses and plants of different sizes are available for such studies – from a laboratory via a pilot up to a production scale.
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)
Coating of particles is a critical process step for many manufacturing processes. After all, coating essentially determines the product quality. The appropriate process must be found to determine the properties of as needed for the application. The following article describes, what need to be considered when developing particles. (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.
