O-4. Factors and new approaches for optimizing lautering operations

Presenter: Travis Audet, AB InBev, St. Louis, MO

Use of lauter tuns for wort separation is an essential step in the recovery of extract converted in the mashing process. The factors affecting lautering are vast, and often only a few fundamental factors are considered. The presentation will first examine pre-lauter tun factors that can have a significant effect on extract efficiency. The presentation will then outline factors involved in the actual lautering process that affect extract efficiency. Finally, a review of innovative approaches to the operation of lauter tubs and resulting improvements in performance will be considered. For all parts of the presentation examples from Anheuser-Busch InBev lauter tun installations will be used.
