During beer processing,there is a part of yeast slurry remaining in the bottom of the tank which still includes some valuable beer. Vacuum drum filtrater or centrifugal is normally applied to recovery the beer in the beer bottom tank. but it is low efficiency because of its low precision separation.
Yeast slurry produced therefrom is about 2~3% of total beer amount, and about 1% of yeast slurry can be reused to ferment again, and the remainder becomes waste disposal. But it is rich in high protein (>45% of total solid content) and beer(90~99% liquid), and used to be treated with plate and frame, vacuum filter or centrifugal in traditional method. But not only it is low efficiency but also produces a lot of waste disposal of diatomite, wastes rich resource.
As a supplier of solution to filtration problem with ceramic membrane for many years, TFT developed a kind of cross-flow filter with ceramic membrane to separate yeast from beer, both recovered large amount of beer and recovered nutritious yeast as fodder, produced high economic benefits.
- Recovering high quality beer
- Reduce lots of waste water disposal with high COD
- Recovering lots of yeast slurry with high nutritious protein
- A green technology, no need of additives
- Closed loop without air entering
- Strong anti-fouling
If you need more details about ceramic membrane process for beer yeast recycling ,please do not hesitate to contact with us or send email to us. TFT is willing to communicate and share information with you on engineering process issues. We are looking forward to developing more market and more applications with your help, bring this new technology to end users, create more values and benefits for all parties.
