Abstract

Effect of fermentation time, number of stages of cultivation, and drying conditions on production of active dry yeast (ADY) was studied in (i) 2-5 and (ii) 25 kg batches. Harvesting yeast after fermentation for 20 h in (i) and 22 h in (ii) and growing in 4 stages were sufficient to obtain ADY. After separating the broth in a nozzle centrifuge, conditioning of the cream in 3% sugar for 10 h gave added benefits. Of the drying methods studied (cross flow, truck drier, batch through-flow drier and fluidized bed drier), the batch through-flow drier was found suitable for small-scale operations, and fluidized bed with an operating temp. of 45 degree C was optimum for large-scale drying.
