Sprühgranulation
Sprühgranulation, or spray granulation, is a process used in food, chemical, and pharmaceutical manufacturing to convert fine powders into granules by spraying a liquid binding solution onto a powder bed while drying with heated air. The sprayed droplets bind particles as the solvent evaporates, forming granules with defined size, density, and porosity.
The process is typically carried out in a spray granulation reactor that combines a nozzle for atomizing
Common binders include polyvinylpyrrolidone (PVP), hydroxypropyl cellulose, carboxymethylcellulose, and various polymers; solvents are often water or
Applications are widespread in the pharmaceutical industry for producing granules suitable for tablet or capsule manufacture,
