How to choose the right centrifuge for your brewery
Selecting the correct centrifuge size for your brewery is not an easy task, with many designs and manufacturers to choose from. Key factors to choose the right model include the amount of solids, throughput and what you are trying to accomplish.
Globally, centrifugation technology is a topic of major interest. It’s a proven technology and the probrewers are aware of the multiple benefits of centrifugation technology in the beer process.
Consistency, quality, faster turnaround of tanks, control of losses, as well as greater control over contact time of ingredients with beer are well known benefits.
But while many craft brewers make a centrifuge the first piece of equipment they are looking to invest in or upgrade, there are several factors to consider when choosing the correct centrifuge size and system for your brewery.

When it comes to dry hopping, craft brewers tend to dose a much larger volumes compared to legacy brewers. Depending on the solids content, you can recover more or less beer from the bottoms. Typically, 50% of tank bottoms is valuable beer. With the brewing centrifuge that translate to 5% up to 15% increase in beer yields, which can be achieved with even the smallest models such as the Alfa Laval Brew 20.
The Alfa Laval Brew Series caters for breweries with small batches up to commercial production. The smallest model, the Alfa Laval Brew 20, has a working capacity of 4 – 15hl/h, which makes it ideal for a brewpub or microbrewery with 1 – 2 fermentation tanks. The Alfa Laval Brew 80 has a working capacity of 50hl/h and the Alfa Laval Brew 2001e delivers up to 750hl/h.
Longer Shelf Life
Oxygen pick-up is among the major concerns for all breweries but especially for craft brewers producing hoppy oxygen sensitive IPAs, negatively affecting the product’s shelf-life stability. Even Alfa Laval’s smallest multi-purpose centrifuges for craft brewers, the Alfa Laval Brew 20 and Brew 80, have a unique axial hermetic seal that allow brewers to achieve minimal ppb pick up levels of dissolved oxygen without requiring CO2 or deaerated water.
If you need zero dissolved oxygen pickup, for instance for canning, distribution and export, consider a larger bottom-fed model such as the Alfa Laval Brew 250 or Alfa Laval 701 eMotion as a polisher.
