Coldblock - challenges and solutions

• High cost
• Reliance on commercial yeast strains
• Limited opportunity for creativity

• Yeast Management Systems: 
  • Alfa Laval 3-in-1 yeast module, or
  • Alfa Laval Yeast propagation plant

• Ability to rehydrate, propagate and re-use yeast
• Fully customizable solution

• Inconsistent or slow fermentation profile

• Alfa Laval Rotary jet mixers

• Up to 40% faster fermentation
• Improved homogenization during fermentation
• Optimized alcohol extract yield
• Flexibility – mobile unit that can be moved between tanks

• Long sedimentation time
• High beer loss
• High turbidity
• Low yield
• Need to grow production capacity

• Alfa Laval BREW series of centrifugal separators

• Increased production capacity owing to speed of clarification without the need to expand fermenting capacity
• Beer recovery up to 15% compared with draining
• Ability to clarify beer when profile is right
• Extended shelf-life unblemished by haze (especially important for exports)
• Fast emptying of separators also means higher rotation of tanks which provides extra capacity without further investment
• Average 3% increase in yield between fermenting vessel and bright beer tank depending on operating procedures

• Up to 8% yield improvement in low to medium flocculating yeast strains

• Slow process and beer loss

• Alfa Laval dry hopping equipment:
  • Alfa Laval Alhop
  • Alfa Laval Iso-Mix External Drive (IMXD)

• Maximized use of hops
• Accelerated dry hopping process
• Homogenization of beer streams to improve downstream hop removal via centrifugation
