Alfa Laval Clara 20 Disc Centrifuge | Food Grade Stainless Steel Clarifier


The Alfa Laval Clara 20 is a compact, skid-mounted centrifugal separator designed for clarification and purification applications in various industries, including food, beverages, and industrial fermentation. Here are the key points about its design and functionality:

The Clara 20's compact size, gentle handling of shear-sensitive products, and ability to separate solids, liquids, or both make it a versatile solution for various clarification and purification needs across multiple industries.

The LAPX-404 is applicable for the removal of suspended solids with particle size of 0.5 t0 500 µm. The liquid centrate has a lower density than the solids.

The solids content is usually in the range of 0,1 to 10% by volume. The total solids content can be from 0.1% to 10% by volume.

The following are some of the popular applications the Alfa Laval LAPX-404:

The maximum process capacity of the machine is 15 Gallon/Minute.


The bio-culture fluid enters the rotating bowl of the LAPX-404 centrifuge. The bowl exerts a high g-force (11,000 Gs) on the process fluid.

The centrifugal force causes rapid sedimentation of the cells. These separated cells are auto-ejected from the centrifuge.

The liquid phase (broth) moves towards the centers and exists the bowl through a separate outlet.

A detailed explanation of the operation of the LAPX-404 centrifuge follows.

The process fluid enters the rotating bowl of the centrifuge through a stationary inlet pipe (1). The distributor (2) accelerates the fluid before it enters the disc-stack (3).

The separation of the solids from the liquid happens in the inter-disc space.

The clear liquid moves towards the center of the bowl. A paring disc (4) pumps out the clear centrate.

The denser solids move towards the bowl periphery. From there, their ejection happens through the centrifuge cyclone.

A hydraulic mechanism located under the bowl separation space causes the sludge ejection. This mechanism forces the sliding piston (5) downward, opening the solids ejection ports (6) at the bowl periphery.

The cyclone reduces the high ejection velocity of the solids.
