DIOSNA revolutionized the science of granulation over 80 years ago with the introduction of their vertical bowl design. Today their original design is the most used granulator configuration in the world today (a little known fact). Often copied but never duplicated, DIOSNA provides the most complete and state-of-the-art line of granulators available.

High Shear Granulating is a highly effective method of producing a uniform dense granule. The machine's function is simple in principle. Dry powders are first loaded into the granulator by vacuum or gravity (total containment is simple, call for details). The DIOSNA granulators are extremely quick and efficient mixers of dry powders. Dry mixing is the first step of the process. After the products are mixed by means of our unique, bottom drive rotating tool (impeller), a binder is introduced into the product. The binder can be added in dry form or sprayed in as part of a binding solution. Spraying occurs though one or more spray nozzles and is quickly dispersed into the product by the mixing action of the main mixing tool (impeller) and the chopper blade. The chopper blade, which is positioned in the highest circumferential area of the product aids in de-lumping. Once all of the solution is in the granulator, the impeller and chopper work together during the wet massing phase to produce dense granules of uniform particle size. The system quickly forms granules that are then easily and automatically discharged from a port in the bowl's side. The wet granules are generally milled as they come out of the granulator. The granules then need to be dried in ether an oven (old labor intensive technology) or a DIOSNA Fluid Bed Dryer machine (see fluid beds).
