Alfa Laval has supplied high-quality separators to the brewing industry for decades. Alfa Laval brewery separators have proved crucial in enabling breweries around the world to achieve higher yields from greater efficiency, and in helping them meet changing demand patterns while maintaining profitability. Brewery separators from Alfa Laval ensure minimal levels of oxygen pick-up during passage through the separator, which is a major quality requirement for brewers. Hygiene issues are also a prime focus in all aspects of the design of these brewery separators.

The BREW series separators are all normally used within the following application steps in the brewing process:

  • pre-clarification
  • green beer separation
  • hot wort separation
  • beer recovery

With features and options such as Oxy stop, a hydrohermetic seal that ensures minimal oxygen pick-up in the clarified liquid, SmartEject self-triggering system, which provides intermittent discharge of solids that have a high dry matter content, a specially designed variable frequency drive (VFD) system provides benefits that include low starting current and a short time power supply, and much more, the brewer can customize the separator performance and capacity to a given application task to the optimum yield.

How it works

 How its works - Note Image might not correspond fully with describing text. Please refer to Documentation for more detailed info

The feed is introduced into the rotating centrifuge bowl from the top via a stationary inlet pipe and accelerated in a distributor before entering the disc stack. Separation takes place between the discs. The product moves towards the centre of the bowl, where it is pumped out under pressure by means of a built-in paring disc.

The heavier solids phase is collected at the periphery of the bowl, where it is discharged intermittently via the centrifuge cyclone. The solids are discharged by a hydraulic system below the separation space in the bowl, which forces the sliding bowl bottom to drop down at suitable intervals, thus opening the solids ports at the periphery of the bowl.

The self-triggering system works by introducing a sensing gas into the sensing chamber from the top. When the accumulated solids reach the outer periphery of the sediment-indicating disc, the pressure in the sensing gas line alters. This pressure change acts via the control system to trigger a discharge.
