Glatts Technology Center in Weimar stands for innovative technologies for the production of granules and pellets from powders and/or solid-containing liquids. Glatts 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.



At the heart of all process engineering activities are fluid bed technologies and spouted bed technologies for the production of innovative products for all powder processing industries. The focus is on continuous processes for the processing of powdery substances into attractive, dust-free, easy dosage and easily soluble granules and agglomerates for food, detergents, fertilizers, pesticides, pharmaceuticals and many other applications. Batch processes are also offered.
Granules can be used in a great variety of applications. Examples include wash-active substances such as surfactants and enzymes in the detergent industry, instant granules such as cocoa drink or baby food that immediately dissolve in contact with water or milk. A special application is the encapsulation of flavoring agents such as orange oil. Fine droplets of oil are embedded in sugar granules (maltodextrin). In this way, not only an easy dosage of the flavoring agent but also its protection against oxygen can be ensured. Thus, it can be stored over longer periods of time. Also sweeteners and preservatives such as phosphates and benzoates are granulated for better dosage.
The most common basic processes for granulation:
  • Spray granulation for compact granules from fluids
  • Agglomeration for dust-free instant products from powders
  • Coating for the functionalization of particles
  • Encapsulation of liquids for stabilization of sensitive substances
Several pilot and production plants are available for scale up  from laboratory tests. A certification as per ISO 2010:9001 and an established HACCP system for the contract manufacturing unit underline Glatts quality standards.
The equipment of Glatts Weimar Technology Center ranges from latest fluid bed and spouted bed plants up to complementary apparatuses such as high-shear granulators, extruders, pelletizers and tablet presses.
The laboratory uses a great variety of devices for the determination of product properties including digital microscopy, particle size and shape distribution (laser diffraction), thermoanalysis (TGA, DSC), sorption and desorption, abrasion, bulk density, humidity as well as fluid properties such as particle size or droplet distribution in suspensions or emulsions, fluid rheology, pH value and conductance.
