Vacuum Wort Boiling.Peer-reviewed article

I. SENGE

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 is easy assembly and possibility to increase a brews number (brewery capacity).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).
