The article summarizes present findings in the scope of beer pasteurization with special emphasis on the risks of inaccuracies related with the use of the variable of "pasteurization unit" (PU). Beside the theoretical part concentrated on the process of calculation of the pasteurization effect, the paper discusses factual parameters that affect the really attained pasteurization results. First of all, it concerns the microbiological factors influenced by the characteristics of the specific contaminating microorganisms (decimal reducing temperature and time, pasteurization period), then the...

German factory ZIEMANN has developed a new equipment- vacuum wort boiling plant - for wort boiling with the goal to reduce a primary energy and to increase a content of coagulable nitrogen (cN) and thiobarbituric acid figure (TBAF). This equipment consists of flash evaporator, vapour condensator, vacuum pump, this plant is connected via By - Pass with wort pipe line. Obtained results at the rate of evaporated water 4 - 5 % and vacuum 0,06MPa (abs.) showed appr. 50 % primary energy saving, further increased foam stability, and improved wort composition (cN content, TBAF, and the other parameter). The next advantage...
