SchoKo process and heat balance in breweries
The "SchonKoch" (gentle boiling) process from Kaspar Schulz Brauereimaschinenfabrik is used in over 25 breweries. The effect on the overall heat balance in breweries has repeatedly come in for criticism in this process. Taking Private Brewery M.C. Wieninger GmbH & Co. KG as an example, the ramifications of the SchoKo process on the overall heat balance of a brewery were investigated.
Using the SchoKo process, an exis- ting wort boiling system can be extended by adding a vacuum evaporator requiring little space. Fig. 1 shows a schematic diagram for such a boiling system. After lautering, the wort is heated to about 1 K below boiling temperature in the existing wort copper. This is followed by a hot holding phase of 30 to 45 minutes during which the wort does not boil. ...
