Abstract
Process for the preparation of active dried microorganism mass and in particular active dried baker's yeast, comprising a disintegration of a compressed mass of microorganisms into particles and drying these particles in a fluidized bed drying equipment without previously dried air up to a dry matter content of from 75 to 90%, whereafter the particles of the microorganism mass are additionally treated in a vacuum drum, at a temperature of from 25 to 45'C and a pressure of from 1-10 mm Hg (133-1330 Pa), until the particles have reached a final dry matter content of from 90-98%. Preferably yeast particles are initially dried in a fluidized bed dryer using air of an initial temperature of from 90-130'C and having a space velocity in the bed of 0.8-2.0 m/s, while the particles are kept on a wet-bulb temperature of at most 45'C, and whereby the load of the fluidized bed dryer is 100-1000 kg/m<s2>s floor area. More preferably a surface active agent is added to the microorganism mass before drying.
