Slide 6: Dry hopping solutions
Dry hopping solutions Alfa Laval IMXD and Alfa Laval Alhop Alfa Laval Alhop module Alfa Laval IMXD integrated system Skid-mounted system Integrated in the fermentation/maturation vessels Hops remain outside the main vessel Hops are mixed within the main vessel For smaller volumes, 50-500kg

Slide 16: Centrifuges - a great tool for brewers
Centrifuges - a great tool for brewers − Reasons to install a centrifuge • Clarify beer – remove coarse solids and improve quality • Reduce beer losses – increase yield • Control the contact time of ingredients in beer • Increase production capacity - reduce sedimentation time • Replace or combine w
Slide 17: Clarify or polish with same tool, different flowrates
Clarify or polish with same tool, different flowrates Typical particle size distribution in lager beer It’s not a filter is it a clarifier or polisher ? in fact, it is a “classifier” Following Stokes law, the larger the particules, the easier to separate: • Reduced flow ▪ less particles in the clari
Slide 18: Flow rate
Flow rate − Altering the flow rate has the largest effect on clarity Brew 20 4-15 hl/h Note Inlet beer, left glass, has been clearing naturally in a tank for 1 month prior to Flow rate Flow rate Flow rate centrifugation. Something 15 hL/hr 10 hL/hr 5 hL/hr that is uncommon for most breweries www.alf
Slide 19: Flow rate
Flow rate − Altering the flow rate has the largest effect on clarity Brew 80 10-50 hl/h Feed inlet Flow rate Flow rate Flow rate 18 hL/hr 22 hL/hr 28 hL/hr www.alfalaval.com
Slide 20: Polished beer & Hazy beer
Polished beer & Hazy beer • Bright to near bright beer styles without filtering • Possibility to adjust desired final haze • Reduces/remove the consumption of consumables such as filter aids 10/08/2023 | © Alfa Laval 20 | www.alfalaval.com
Slide 21: Process improvements for more yield
Process improvements for more yield − Racking cane or Stand pipe feed • Transfer prior to cooling • Feed from racking pipe/stand pipe − Blending with tank bottoms 10/08/2023 | © Alfa Laval 21 | www.alfalaval.com
Slide 22: More yield with the centrifuge
More yield with the centrifuge − Example from a customer brewing Hazy IPA styles with a high solids content (22g hops/L) Without a centrifuge With a centrifuge Beer loss Beer loss 4 HL 6 HL ~10% Beer Beer more yield if using 14 HL 16 HL a centrifuge FV – 20 HL FV – 20 HL | © Alfa Laval 22 | www.alfa
Slide 23: Return of investment example
Return of investment example − Based on yield increase only Payback point ROI (Capex) • Fermentation vessel: 20 hL €3000 000 • Yearly production: 2000 hL €2500 000 • Suggested flow rate: 5-10 hL/hr €2000 000 Brew 20 • Recovery rate for IPAs – €1500 000 Yield increase ~ 8% €1000 000 €500 000 • Beer s
Slide 24: Centrifuges in breweries
Centrifuges in breweries − Summary A centrifuge will contribute to: • Clear beer with little or no filtering • Quicker tank turn-over • Beer recovery & reduced product loss • Improved quality & consistency • Improved filter performance • Control haze in the beer | © Alfa Laval 24 | www.alfalaval.com
