A method for producing enzyme granulates, the resulting enzyme granulates,
and their use in formulations, e.g., for animal feed, food, washing
means, rinsing means, and/or for pharmaceutical purposes and the like.
The enzyme granulates show, in particular, a high relative percentage of
active enzymes, certain grain sizes, good storage stability, especially
small roundness factor, and/or low residual moisture percentage as well
as preferably additional specific properties. According to the invention,
the enzyme granulates are produced by linking the thermal conditions in
the spray zone and the temperature conditions in the remaining region of
the fluidized bed. In the process according to the invention, this is
achieved in that the supply of heated processing gas is realized for
drying exclusively in the injection region. The reliable supply of
particles in the injection region is realized through the special
geometrical shape of the apparatus under the use of gravity. Through the
addition of inert particles as nuclei material for cores, the absolute
content of enzyme activity of the enzyme granulate can be controlled.
