Brewhouse – Challenges and solutions for breweries

Equipment for brewhouse efficiency

High energy usage, ingredient loss, high water consumption and spoilage are just some of the most common issues in wort production. Cleaning and fouling can also impact process times and then there's the problem of what to do with the trub and spent grain.

Alfa Laval offers extraordinary solutions to ordinary problems, to ensure efficiency and excellent performance in craft and commercial brewing.

Wort preparation

Slow wort production, high energy usage, ingredient loss, high water consumption and spoilage are some of the issues in wort production and fermentation. Ordinary issues for which we have extraordinary solutions to raise brewhouse performance.

Industrial equipment for brewhouse efficiency 640x360

Challenge

  • Oxidation during mashing and risk of staling

Outcome

  • Increase in yield by pushing out all beer lines with deaerated water
  • Improved beer flavour stability and shelf life

Challenge

  • Too wet spent grains

Solution

Outcome

  • Dewatered spent grains up to 70% humidity

Challenge

  • High energy consumption

Solution

Outcome

  • Energy reduction of up to 40% by reuse of energy from wort boiling to heat subsequent brews

Challenge

  • Poor heat transfer due to fouling of brew kettle and poor cleaning

Outcome

  • Replacing spray balls with rotary jet heads that handle in-flow particulates to clean all brew kettle internal surfaces helps improve brewhouse efficiency and hygiene

Whirlpool

Separation of trub, pelletized or whole hops from your wort, ensuring a cleaner final product and improving overall beer quality before fermentation.

Challenge

  • Loss of wort and considerable beer waste
  • High carry-over of solids to wort cooler may cause fouling 
  • Potential high disposal cost of waste trub

Outcome

  • Recover 99% of wort otherwise lost as trub, yielding more beer
  • Reduced whirlpool time and less energy and water consumption
  • Higher hop utilization from counter-current flushing of solids
  • Reduced disposal and reduced fouling/clogging in wort cooler
  • Convert trub into valuable by-product

Challenge

  • Wort quality
  • Wort loss
  • Inefficient trub separation sequence
  • Trub too wet causing downstream and disposal issues

Outcome

  • Improved wort clarity before cooling
  • Recovery of wort lost as trub increases overall yield
  • Shortened process times and improved trub separation
  • Significantly drier trub (which can be sold on as animal feed additive)
  • Less risk of wort cooler fouling
  • Reduced flushing and energy consumption between brews
.

Wort cooling

Rapidly lower the temperature of the boiled wort before fermentation, preventing contamination and promoting healthy yeast activity.

Challenge

  • High energy cost

Outcome

  • Energy reduction of up to 40% by reuse of energy from wort boiling to heat subsequent brews
