The SAAN granulators are extremely quick and efficient mixers of powder. 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 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 acids 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 SAAN Fluid Bed Dryer machine.
