  • Evaporation - A Wastewater Treatment Alternative | WWD

    These wort boilers achieve high heat transfer through two phase flow and nucleate boiling, and operate at low steam pressure (at 3.0 to 3.5 bar) to heat the boiler. In these kettles vigour can be introduced mechanically, by wort circulation, and the classical 10% evaporation/hour with a 90- minute boil, can be reduced to 5% to 6% evaporation/hour with a 60-minute boil without loss of wort/beer quality.Learn More
