FLUID BED PROCESS FOR THE PRODUCTION OF ENZYME GRANULES |
摘要 |
The invention describes a process for the continuous production of enzyme granules characterised in that:(h) a liquid enzyme preparation containing on e or more enzymes is produced(i) optionally additives are added to the liquid enzyme preparation obtained in (a)(j) one or more liquid enzyme preparations obtained in (a) or (b) are sprayed into a fluidised bed by means of spray nozzles(k) fine material that escapes from the fluid bed with the off-gas is separated off and returned to the fluidised bed as nuclei for the granule formation(l) granules of a predetermined size are formed by adjusting the sifting gas stream(m) the finished granules are discharged via one or more countercurrent gravity sifters installed in the inflow plate of the fluidise d bed apparatus(n) optionally the enzyme granules obtained in step (f) are coated.The invention further provides enzyme granules characterised by an isotropic structure, a spherical shape and smooth surface as expressed by a roundness factor between 1 and 1.6 and optionally a coating.
