The right particle structure determines the success of your product. Fine powders tend to form lumps when in contact with liquids. These can only be dispersed by appropriate stirring technology and high shear forces.
Instant powders can be precisely dosed, dissolve quickly and without residue, and do not form lumps or segregate.
Transform your powders into porous, dust-free, easy-flowing and homogeneous granules by means of Glatt fluid bed spray agglomeration!
Fluid bed spray agglomeration of fine powders enables the production of porous granules with a defined particle specification. Due to the relatively low mechanical forces during agglomeration in the fluid bed, agglomerates with a capillary structure, porous surfaces and only a low dust content are produced. These are the best prerequisites for good wettability. These products therefore have excellent dispersibility and are soluble in water. They have a low bulk density and their particle size distribution – usually between 0.2 and 2.5 mm – can also be controlled. The interconnected powder particles are homogeneously distributed and improve flowability and reduce electrostatic charging.
A wide range of effects can be achieved via the choice of spray medium, its composition and concentration. Simply changing the viscosity of the spray solution influences the internal structure. With a constant formulation, the product properties are thus changed in a targeted manner. In principle, additional additives can also be introduced via the spray liquid during agglomeration in the fluid bed. In this way, for example, the consistency of sauces or the rehydratability of starch can be improved. Raw materials with fatty components, such as chocolate powder, require an emulsifier for better dispersion.
High dosing accuracy, flowability and uniformity are also required for instant products for beverage vending machines. In particular, a defined bulk density for volumetric metering is important here.
At the Glatt Technology Center in Weimar, we work with you to determine the optimum process conditions for your product in feasibility trials for product development. Various laboratory facilities and comprehensive analytical equipment are available for this purpose. On our pilot plants, we optimize the process and scale it up reliably to a stable and economical production scale. The results from this form the basis for the design and construction as well as the erection of your fluid bed or spouted bed plant, tailored to your requirements. As an alternative to our own process technology, we offer you the outsourcing of your production by means of contract manufacturing at Glatt.
