Manufacture of enzyme spheres

Abstract

Abstract A PROCESS FOR THE MANUFACTURE OF ENZYMATIC COMPOSITIONS IN SPHERICAL FORM, HAVING INCREASED STABILITY UPON STORAGE AND ON EXPOSURE TO OXIDIZING AGENTS, WHICH COMPRISES MIXING A NORMALLY SOLID ENZYME WITH A NORMALLY SOLID SYNTHETIC ORGANIC SURFACE ACTIVE AGENT AT A TEMPERATURE AT WHICH THE ENZYME IS STABLE AND FOR A PERIOD LONG ENOUGH TO FORM A HOMOGENEOUS MIXTURE THEREOF, COMPRESSING THE MIXTURE UNDER PRESSURE AND MECHANICALLY WORKING IT TO MAKE IT PLASTIC, FORCING THE WORKED MIXTURE THROUGH SMALL OPENINGS TO PRODUCE FILAMENTS THEREOF HAVING A DIAMETER APPROXIMATELY THAT OF THE DESIRED SPHERES, ROLLING A BED OF FILAMENTS OF SUCH LENGTHS IN FRICTIONAL CONTACT WITH SURFACES TO RUB OFF PORTIONS THEREOF, CONTINUING SAID ROLLING UNTIL THE FILAMENTS ARE REDUCED TO A LENGTH ABOUT THAT OF THE DIAMETER THEREOF AND ARE ROUNDED INTO SPHERICAL SHAPE, AND REMOVING SUCH ROUNDED PARTICLES FROM AN UPPER PORTION OF THE BED; AND THE ENZYMATIC COMPOSITIONS PRODUCED THEREBY.
