Beer recovery from yeast

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. 

Why should you choose our M&L‘s Cross Flow-Filtration System (CMF) ?

• High quality of the recovered extract (beer)
• High yield in yeast recovery through specially developed filtration and cleaning processes
• Very short payback period (1 - 2 years, depending on brewery size)
  
• Use of chemically and mechanically robust ceramic membranes
• Significantly reduced water and cleaning agent consumption through targeted process optimization.
• Minimal need for operating personnel
• High microbiological safety due to easy cleaning and sterilization with hot water up to 90°C (194°F).
• Modular, easy expansion of existing systems
• Sterile filtrate using a 0.2-micron membrane
• Low maintenance costs
