Brewing liquor pre-cooling using H2O/LiBr absorption refrigeration plants
In 1873, Carl von Linde provided proof at the International Brewing Congress held during the World Fair in Vienna that direct cooling of air or a liquid with a refrigerating machine with high efficiency was more favourable in cost terms than the small refrigeration units used up to then for production of ice. Shortly thereafter, the first NH3 refrigeration plant was installed and operated at Spatenbräu in Munich. This was followed by an installation at the Dreher Brewery in Triest in 1877.
With few exceptions, refrigeration in breweries is nowadays provided by compression refrigeration plants (CRP) driven by electric motors.
The absorption cycle is the oldest refrigeration process, known since 1777 (1). Y.
