J. ŠROGL, J. FAMĚRA, J. GUBIŠ, P. BOUŠOVÁ

Some aspects of production modernization in Czech breweries with accent to beer filterability are discussed: whirlpools introduction was accompanied by a higher sludge substances contents in hopped wort. The yeast different sedimentation is influenced by vessels' geometry during fermentation process in cylindro-conical tanks. The sludge substances sedimentation was influenced by the authors by adding of auxiliary means on the carageenan polygalactane and silica gel basis, attaing thus better results with those on carageenan basis. For the purpose of filtration stabilization there were, during the final phase, added some means on the isinglass basis as Well as enzyme preparations (cellulase, ß-glucanase). The beer filterability unceasingly represents a problematic part of a modern technology and has to be always solved for every definite case.
