Process for encapsulation of substances sensitive to oxidation as well as fragrance and flavorant compounds in granular form

摘要

Production of granules comprises injecting liquid formulations containing a material to be encapsulated via spraying units into a gas stream, drying and granulating the material particles in the gas stream, separating the particles from the gas stream and feeding into a process chamber, feeding the particles to a gas inlet region via inclined surfaces under gravity, removing fine particles, dust and particles entrained by the process gas and introducing to the process as seed material for granule production and producing a sold flow by introducing material into the gas stream.
