Wort boiling: proper evaluation of boil-off processes – Part 1: Basics of evaporation
With a loss-free boiling system without heat recovery, energy requirements during boiling are dependent only on overall evaporation. This series of articles is meant to shed some “light on boil-off processes” and to encourage readers to question some promises made. In the first part, the general basics of various types of evaporation are described, before going on to Part 2 where these are confirmed in industrial-scale tests. Part 3 deals with the differences in current widely used boiling systems. Part 4 addresses the question of how the necessary overall evaporation can be reduced in real terms.
