Modern wort boiling
The launching some decades ago of closed wort boiling and, soon afterwards, the introduction of low-pressure boiling with a lower total evaporation rate has rerouted conventional atmospheric wort boiling in breweries onto a new track, initiating a novel approach. This contribution deals with details of low-pressure boiling and describes possibilities for energy storage.
The second oil crisis in 1978/79 caused breweries to look in great detail into possible energy savings potential and heat recovery options. At that time, such techniques became very important. After the first oil crisis in 1973/74, the average market price for light heating oil in Germany between 1975 to 1978 was around 24 DM/hl (= 200 DM/t coal equivalent).08 bar (tb = 102°C) to 1.
