Fluid Bed Dryers Granulators - Production Fluid Bed Multi Processors

O’Hara’s Fluid Bed Multi Processor performs granulation of fine powders by spraying aqueous or a solvent binder solution onto a fluidized powder bed (top spray granulation) or by concurrently spraying aqueous or a solvent binder solution into a segregated dilute phase powder stream bottom spray granulation. The process variables can be adjusted to account for changes in the product particle size, bulk density, and flow characteristics. Production capacity of these pieces of equipment varies from 30 kg up to 500 kg.
