Abstract
Dust free enzyme containing particles are produced by coating hydratable core particles with an enzyme and then with a film-forming macro-molecular material. Coating is carried out by suspending the core particles in a fluidized bed dryer, spraying an aqueous slurry of enzyme onto the core particles while suspended, and evaporating water to leave a dried enzyme coat on the particles. The resultant enzyme-coated particles, while still suspended in the fluidized bed, are sprayed with a solution or dispersion of the macro-molecular material, and dried to remove solvent to leave a coating of the macro-molecular material.
