AFPX separators are used in meat, fish and blood processing industries to purify and enhance recovery of valuable protein fractions, fats and oils. These robust and high performing separators are especially designed for extremely demanding separation duties in order to meet the tough requirements of the food industry and exceptionally high hygienic standards. With an AFPX separator from Alfa Laval, you can achieve exceptional, high-quality fats and oils with 99.7% purity.

AFPX 高速离心机-AFPX High Speed Centrifuge

For demanding separation duties in fish and meat industries

  • Easy to operate and maintain
  • Excellent wear and corrosion resistance
  • Longer running times which ensures increased yield
  • Cleaning in place (CIP) facility to keep the costs down
  • Small footprint
The protein business is highly competitive, and to be profitable you need to maximize quality and yield while keeping operating costs low. At Alfa Laval we have more than 30 years’ experience from designing rendering, fat melting and protein recovery separation systems. We know how you can reduce your environmental impact and get the extra percent of product out of your raw material that make all the difference to your bottom line.

Key features of the AFPX range of centrifuges are their ability to handle high flow rates, high solids content and high-temperature processing. These functions make it the ideal choice to handle the tough conditions encountered in the animal and fish processing industries.

Depending on duty and feed composition, the AFPX disc stack separator can be configured in three different executions: concentrator, purifier and skimmer.

In addition, the AFPX  combines a high G-force, high sludge capabilities and automated operation.


The AFPX was designed to discharge solids intermittently, while at the same time separating two intermixed and mutually insoluble liquid phases of different densities. The centrifuges comes in a series of optimized executions that  are suitable for a considerable number of duties, including  separating fish press water, stick water and extracts. Other applications include the purification of fish oil and liver oil, animal fat, peel oil, and similar products.

How it works

Typical bowl drawing for a solids-ejecting centrifuge. Drawing details do not necessarily correspond to the centrifuge described

Separation takes place inside a rotating bowl. The feed is introduced to the rotating centrifuge bowl from the top via a stationary inlet pipe, and is accelerated in the distributor, before entering the disc stack. The distributor is designed especially to ensure smooth acceleration of the feed liquid.

The separation of liquid-liquid-solids takes place between the discs, with the oil phase moving through the disc stack to the centre and is discharged through pipes and sprayed out into the collecting frame. The water and solids separated from the oil moves out to the periphery, the water is led via channels in the top disc to the paring chamber, where it is pumped out of the rotor with means of a built-in paring disc.

The solids are collected in the periphery, from where it is discharged intermittently via the centrifuge cyclone. The solids discharge is achieved by a hydraulic system which at preset suitable intervals forces the sliding bowl bottom to drop down and thus opening the solids ports at the bowl periphery.
