Homogeneous product mixtures through agglomeration of the powder particles
Product blends make handling easier for the user. Whether it is instant soups, powdered beverages or the homogeneous distribution of active ingredients in a carrier, the precise weighing of the components in different quantities and the mixing process can be realized much more easily in large-scale plants.
But what if the starting materials are very different in terms of density, particle size and shape? Here, spray agglomeration of powders in the fluid bed of the mixture can counteract segregation in subsequent processes, packaging or transport. By spraying on a binder solution, the surface of the mixture is wetted and fine particles agglomerate into larger granules or are adhered to coarser particles. However, if the shape and size are too different, fine particles can alternatively be sprayed on together with the binder solution and thus be homogeneously distributed over the coarser components. This is also a suitable procedure for active ingredients that have to be introduced in very small quantities. The simultaneous agglomeration by the binder improves the flowability and reduces dust formation.
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.
