What effects have baffle plates in fermenters upon the cultivation process.Peer-reviewed article

Z. AUNICKÝ

Two plants modeling industrial installation in 4:1 and 2:1 scales were built to study energy input and specific oxidation as a function of the number, width and angle of baffle plates in fermenters. It has been established that the intensity of oxygen transfer does not depend on the mentioned parameters of baffles, but with their increasing numbers and width energy input, as well as specific energy input are higher by 4 to 18%. Both energy input and specific energy input can be reduced by 19 to 37% by setting the baffles in the direction of liquid flow. Maximum heat transfer can be, consequently, achieved with various designs cooling surfaces.
