METHOD OF BEER CONTINUOUS MAIN FERMENTATION AND AFTER-FERMENTATION AND EQUIPMENT FOR REALIZATION OF THIS METHOD

摘要

The essence of the invention is that main and after-fermentation is performed by a gravitational, continuous flowing process, whereas main fermentation occurs in the first phase homogeneously at 5 to 7 degrees C in the presence of oxygen at a concentration of 5 to 7 mg.1-1 and in the next phase it occurs heterogeneously first at 8 to l0 degrees C and then at 6 to 18 degrees C. After-fermentation occurs at overpressure of 0.05 to 0.1 MPa first at 5 to 9 degrees C, then at 8 to 6 degrees C and finally at -l to 0 degrees C. The apparatus consists of a work collecting tank and yeast starter bin, which are connected through a dosing device to the lower part of the first element of the battery of cylindroconic fermentation tanks, equipped with cooling and yeast draw off, whereas the first member is equipped with sterile air in-feed and individual members are joined together always from the upper part of the previous to the lower part of the following element and the lower section of the last element of the battery of fermentation tanks is connected to the upper part of the first member of the battery of pressure cylindroconic after-fermentation tanks, equipped with cooling and yeast removal, which are joined together always from the upper part of the previous to the lower part of the following element. After the last after-fermentation tank there is filtration element and collection tank of ready beer.
