Multi-enzyme granules

A process for the production of enzyme granules having an average particle size of from about 1 to about 2.2 mm and which contain at least two different enzymes comprising the steps of

• A) extruding a first particulate enzyme composition formed by mixing at least one fermentation broth of an enzyme with organic and/or inorganic carrier material;
• B) optionally spheronizing the extruded first particulate enzyme composition,
• C) drying the extruded first particulate enzyme composition as needed to a residual moisture content in the range of from about 4% to about 10% by weight;
• D) forming a second particulate enzyme composition comprised of at least one particulate enzyme different from the enzyme in said first particulate enzyme composition, wherein fewer than about 25% of the particles in the second particulate enzyme composition are smaller than about 0.5 mm in diameter;
• E) mixing the second particulate enzyme composition with the extruded first particulate enzyme composition and a binder to agglomerate the second particulate enzyme composition onto the extruded first particulate enzyme composition to produce said enzyme granules;
• wherein the average particle size of the extruded first particulate enzyme composition is in the range of from about 1.1 to about 3 times the average particle size of the second particulate enzyme composition.
