Abstract
A method of continuous treatment of grain mash for production of ethanol includes enzymatic liquefying of starch-containing particles of raw material in a liquefying container, separating not decomposed coarser particles of raw material in the container, withdrawing the coarse particles of raw material from the container and comminuting the same, and recirculating the comminuted particles of raw material into the container. The starch-containing particles are not ground very fine such as to pass through 1-3 mm diameter sieve openings, and coarse particles withdrawn from the container are comminuted to a fine particle size preferably with a wet comminuting device. By this method, fine particles are obtained with low energy consumption.
