Process combination in the brewhouse - a new wort boiling system and external wort heating
In breweries, unit operations of wort heating and wort boiling as a rule account for the major portion of total energy consumption. Using a combination of a novel wort boiling system with external heating of wort, it has become possible to recover the whole of the waste heat arising in the “wort boiling” unit operation and to supply this to the subsequent brew for "wort heating", with the result that no excess heat arises in the form of warm water. In many instances, there is no requirement for this.
In this paper, achievable improvements in terms of energy requirements and the resulting emission situation will be detailed on the basis of an actual design case.g. coagulation of protein, hop isomerisation, driving off unwanted substances).7 – 0.
