摘要：
Process for fluidized bed granulation of amino acid-containing fermentation broths comprising the stepsIntroduction of a drying gas with a temperature of 100° C.-450° C. into the fluidized bed granulation chamberSpraying of the amino acid-containing fermentation broth into the fluidized bed granulation chamberDischarge of the granules granulated in the fluidized bed granulation chamber with the drying gas stream, anddrying of the discharged granules in a fluidized bed drying step,wherein the discharged granulated granules are a granule mixture with various particle sizes and contains an oversize fraction, wherein the oversize comprises the particle sizes which lie above a desired particle size, an wherein the oversize fraction is removed from the discharged granule mixture and then comminuted and the comminuted oversize and the granule mixture from which the oversize was separated are fed into the fluidized bed drying step.
