Process for dust-free enzyme manufacture

Abstract From the Canadian patent

This invention relates to processes for manufacture of substantially dust-free particles of enzymes by spray-coating solid particulate cores or seeds with fermentation broths containing enzymes. Fermentation broths containing from 5 % to 100 % total solids as enzyme and 4 % - 55 % total solids content in the broth may be used. For broths containing 4 % - 31 % total solids en-, zyme and coating agents may be spray-coated so as to achieve a weight gain of 1 % - 24 % w/w aver the initial weight of the cores. For broths with 31 % - 55 % total solids; a corresponding weight gain of 1 % - 100 % may be achieved. The enzyme coated cores may be further coated with coating agents: The total dry …
