摘要： In a method for the recovery of enzymes, the activity of which after the treatment of starch-containing raw materials used for the production of fermentation alcohol is still not exhausted, the liquid phase containing solutions with still active enzymes after the first separation of the protein fraction is led to a fermentation, then a distillation. The wash water for the protein fraction is provided with a portion of the total amount of alpha-amylase necessary for starch hydrolysis of the raw material and then solids are again separated. The enzyme-containing wash water for the second separated solids is led back into the first enzymatic degradation stage simultaneously with a portion of the slop coming from the distillation.

摘要： An apparatus for continuously producing alcohol by fermenting a mash containing starch, sugar, and similar carbohydrates includes a series of main fermentation vessels and an auxiliary fermentation vessel. The mash, in mixture with yeast, is transferred in succession through the main vessels during normal operation of the apparatus. When the main fermentation vessels are to be cleaned, the further flow of the mash is diverted into the auxiliary fermentation vessel for a period of time sufficient to empty and clean the first main fermentation vessel in the series, whereupon the supply of the mash to the first main fermentation vessel is restored. The gap in the mash supply propagates through the series of the main fermentation vessels so that the remaining vessels can be in turn cleaned as well. By the time the last of the main fermentation vessels is empty, the mash in the auxiliary fermentation vessel is completely fermented so that it can be used to provide continuity in the stream of fermented product leaving the apparatus. The carbon dioxide developing in the fermentation vessels during the fermentation operation is scrubbed with water and the thus CO.sub.2 -enriched water is used for washing the inner walls of the fermentation vessels.

摘要： 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.
