Beer recovery from yeastReducing costs while maintaining quality is a crucial balancing act that breweries across all industries must master in the current turbulent economic climate. Rising raw material and energy prices pose a significant challenge.
CROSS FLOW Filtration (CMF) has been introduced as an alternative method for recovering beer from excess yeast produced during the brewing process. Yeast, a byproduct of beer production, typically contains about 10 to 12% dry matter and leads to beer losses ranging from 2 to 3% of the total beer volume produced.
How does M&L CROSS FLOW Filtration work?Freshly harvested yeast is collected from fermentation or maturation beer in a yeast batch tank before being processed further in the beer recovery system.
From the yeast batch tank, yeast is transferred to the beer recovery system (Cross-Flow system), where it is thickened in a batch process, reaching up to 20%.
The recovered beer, or filtrate, is collected in a storage tank and continuously dosed during the main-stream filtration.
After passing through the beer recovery system (20% w/w) and drying, the recycled yeast can be sold to the feed or pharmaceutical industries.
Compared to centrifuges and filter presses, yeast membrane filtration is designed to produce the highest-quality permeate (filtrate), including taste and clarity. Additional heat treatment or returning the recovered filtrate to the fermentation/maturing cellar is not necessary, ensuring significantly higher cost-effectiveness.
