Coldblock - challenges and solutions

Professional equipment for the fermentation process

A consistent, reliable and effective fermentation process relies on equipment that guarantees high-quality yeast management, hygienic design and accurate control of the process variables.

Our cold block process solutions help overcome common issues to unlock the full potential of your commercial brewery process line.

Yeast management

Challenge

  • Need for yeast propagation, storage and recovery

Challenge

  • Healthy yeast alternative with high viability and vitality
  • Correct pitching
  • High flexibility for propagating, storing and pitching different yeast strains

Challenge

  • Ensuring the supply of uninfected, freshly propagated, high-quality yeast

Solutions

Outcome

  • Yeast with high viability and vitality
  • Correct pitching
  • Homogenous yeast slurry
  • More flexibility for propagating, storing and pitching different yeast strains
.

Fermentation and maturation

Challenge

  • Foaming issues when wanting to improve fermenter utilization
  • Repeatability of fermentation process

Solution

Outcome

  • Less foaming allows increased use of overall fermenter capacity
  • Homogeneous distribution to prevent premature settling of yeast
  • Uniform temperature and CO2 levels
  • Consistent and shorter fermentation time

Challenge

  • Long overall process time in fermenters

Outcome

  • Energy efficient crash cooling
  • Desired temperature reached while transferring green beer

Challenge

  • Subpar hygiene in fermentation systems and interconnecting transfer lines

Outcome

  • Product contact areas effectively and reliably cleaned
  • Optimization of uptimes

Challenge

  • Long sedimentation process time
  • Beer loss

Outcome

  • Reduced maturation time (no need to wait for yeast to settle)
  • Reduced beer losses

Challenge

  • Excess yeast

Outcome

  • Recover up to 88% of your beer from yeast bottom
.

Dry hopping

Challenge

  • Low yield 
  • Repeatability
  • Extended process time when dry hopping on a large scale

Outcome

  • Maximized use of hop
  • Accelerated dry hopping process
  • Improved downstream clarification
  • Improved hop removal

Beer sampling

Challenge

  • Inconsistent, unhygienic and time-consuming product sampling

Outcome

  • Increased sampling quality and frequency
  • Reduced time spent taking samples
.

Cleaning

Challenge

  • Long and costly cycles
  • High energy and chemical usage during cleaning sequences

Outcome

  • Customized, verifiable system
  • 30% saving in cleaning time and chemical consumption
  • Reduced energy for hot (up to 70%) and cold CIP (up to 50%)
  • Optimal recovery and re-use of cleaning fluids
  • Automated operation

Coldblock overall design

Challenge

  • Safe operation of large vessels (yeast management, fermentation, bright beer tanks)

 

Outcome

  • Integrated safety systems
  • Consistent, repeatable and hygienic operation

Challenge

  • Suboptimal cold block design

 

Outcome

  • Avoidance of contamination
  • Optimization of pumps and lines
  • Optimization of complete process and utilities
  • Increased level of process flexibility
