Lautering in Breweries: Status Quo and Future Development Objectives
The lautering process is the solid-liquid separation of a suspension. For this purpose, the international brewing industry mainly uses mash filters or lauter tuns. From a process-technological point of view, this process involves a combination of screen filtration and deep-bed filtration, whereas the deep-bed filtration mainly prevails in the lauter tun. Both are technically sophisticated and technologically specialized processes. The article provides an overview of the status quo of lautering technology in terms of design and performance as well as their respective influence on the beer production. Finally, future research and development objectives regarding the lautering process are presented and put up for discussion.
