METHOD FOR PRODUCTION OF ENZYME GRANULES AND ENZYME GRANULES PRODUCED THUS

摘要

The invention relates to method for production of enzyme granules, enzyme granules produced thus and use thereof in formulations, for example, for animal feed, foodstuffs, washing agents, rinsing agents or for pharmaceutical uses and similar. The enzyme granules have a particularly high relative proportion of active enzyme, particular particle sizes, good shelf life, particularly small rounding factors and/or low residual moisture proportion and preferably further specific properties. According to the invention, the production of the enzyme granulates is achieved by a linking of the thermal conditions in the spraying zone and the temperature conditions in the remainder of the apparatus. The above is achieved in the inventive method by means of the introduction of heated process gases for drying exclusively in the nozzle region. The secure introduction of particles into the nozzle region is achieved by the special geometric arrangement of the apparatus using gravity (see figure). The absolute value for enzyme activity of the enzyme granules can be controlled by means of addition of inert particles as seed material for grains.
