Slide 7: Challenges for the growing craft beer market
Challenges for the growing craft beer market Craft beer production can start in a simple way with home brewing and brew pubs Growing the production of craft beer puts a brew master in front of a dilemma: How to keep the genuine quality while increasing productivity? www.alfalaval.com
Slide 8: Challenges for the growing craft beer market
Challenges for the growing craft beer market Growing craft beer production means: • Implement consistency of production and final beer • Deal with multiple beer styles • Keep beer losses under control • Improving shelf-life How centrifuges can contribute to “keeping genuine craft” while improving be
Slide 9: Reasons to install a centrifuge

Slide 10: Why use a centrifuge
Why use a centrifuge To clarify beer Reduce sedimentation time in fermentation tanks To remove solid particles: yeast, hops, crushed orange peel etc. To reduce beer losses To replace a trap filter clogging regularly © Alfa Laval Slide 10 www.alfalaval.com
Slide 11: Centrifuge is a great tool for brewers
Centrifuge is a great tool for brewers Increase production capacity with the same number of tanks Offer a more linear beer turbidity, suppressing stratification effects Allow brewers to use new ingredients and provide control of the contact time with beer To control turbidity of beers Coarse solids
Slide 12: Filtration:
Filtration: Alternative or complimentary DE filters Lenticular and other dead-end filters Combinations with centrifuge possible www.alfalaval.com

Slide 16: Beer clarification
Beer clarification Quick and efficient removal of yeast, hops and other coarse solids Earlier transfer of the beer • Less time needed for cooling FV and settling of yeast and solids MV Less beer losses. Typically solids are ejected with dryness of 22-23% DM Clarified Beer Defined yeast counts to mat
Slide 17: More yield with the centrifuge
More yield with the centrifuge Without a centrifuge With a centrifuge Beer loss Beer loss 1 HL 2,5 HL Product (beer) Product (beer) ~8% 17,5 HL 19 HL more yield if using a centrifuge Bright beer tank – 20 HL Bright beer tank – 20 HL www.alfalaval.com
Slide 18: Beer polishing & Hazy beer
Beer polishing & Hazy beer Bright to near bright beer styles without filtering Reduces the consumption of potential filter aids FV BBT Controlling proteins and polyphenols in centrifuged beer Clarified Beer Possibility to adjust desired final haze Green Beer Yeast www.alfalaval.com

Separation technology today Important parameters High separation efficiency Minimum oxygen pick-up Low product losses Low power consumption From art to science © Alfa Laval 20 www.alfalaval.com
Slide 21: Centrifugal separation
Centrifugal separation Accelerated settling 8000-13000 g 4000 – 10000 rpm centrifugal Particle particle liquid continuous centrifugal settling size density density phase acceleration velocity (mm Ø) (kg/m3 ) (kg/m3 ) viscosity (m/s2 ) (m/s) (kg/ms) © Alfa Laval 21 www.alfalaval.com d
Slide 22: Avoid particle micronization is key
Avoid particle micronization is key It’s not a filter. Is it a clarifier or polisher? In fact, it’s a “classifier” Typical particle size distribution in lager beer Reduced flow • less large particles in the beer Increased flow • more large particles in the beer By-pass needed • for some hazy beers I

Slide 32: Turbidity discharge triggering
Turbidity discharge triggering For varying feed solids load High outlet turbidity indicate full solids space Discharge triggered before disc stack is blocked QT QT Time © Alfa Laval www.alfalaval.com
Slide 33: Capacity control
Capacity control Capacity control automatically adapts feed rate: to avoid bad separation due to too high feed rate to avoid overfilling Control System the separator with solids FT = Flow Transmitter © Alfa Laval 33 QT = Turbidity Transmitter www.alfalaval.com
Slide 34: By-pass / Blending
By-pass / Blending Features & Benefits • Proportional for defined haze level FV MV • Both yeast and proteins will bypass QT • Defined yeast counts to maturation vessel, which gives consistent maturation Clarified Beer • Can be manual or automated • Bowl speed reduction as alternative Green Beer Yeas

Slide 39: Clarification vs Polishing
Clarification vs Polishing Clarifier type: Polisher type: removal of the bigger particles removes smaller particles > such as yeast or hop particles also reduces the chill haze Slide 39 www.alfalaval.com
Slide 40: For bright and hazy beers
For bright and hazy beers Features & Benefits Polishing - Bright to near bright beer without filtering Degree of polishing defined by inlet flow. The lower the inlet flow, the clearer the beer. Hazy beers using either variable flow rates, variable bowl speed or by bypassing www.alfalaval.com
Slide 41: Centrifuges in breweries
Centrifuges in breweries A centrifuge will contribute to: Clear beer with less or no filtering Quicker tank turn-over Beer recovery Reduced product loss Improved filter performance Controlled haze in the beer www.alfalaval.com
