Applications
Alfa Laval Foodec decanter centrifuges are designed for food
and beverage applications where good hygiene practices are
essential in order to comply with strict sanitary regulations.
These decanter centrifuges are available for both 2-phase
and 3-phase separation. They are ideal for use in the food
industry in situations where the material being processed has
to be separated into either a liquid and a solids phase, or into
two liquid phases and a solids phase.
Standard design
Alfa Laval designed the Foodec decanter centrifuge with a focus
on hygiene, reliability, easy access and low noise levels. The
rotating assembly is mounted on a compact welded box beam
frame with main bearings at both ends. The cover is hinged to
enable easy access for inspection, cleaning and maintenance.
The in-line motor is mounted on the decanter with adjustable
brackets to make it easy to adjust belt tension. The bowl is driven
at the inlet end by an electric motor and V-belt transmission.
The bowl, conveyor, casing, inlet tube, outlets and all other
parts in contact with the process media are made of AISI 316
stainless steel and duplex stainless steel.

Operating principles
Separation takes place in a horizontal cylindrical bowl
equipped with a screw conveyor. The product is fed into the
bowl through a stationary inlet tube and is smoothly
accelerated by an inlet rotor. Centrifugal forces cause instant
sedimentation of the solids on the wall of the bowl. The
conveyor rotates in the same direction as the bowl, but at a
different speed, thus moving the solids towards the conical
end of the bowl.
The new Foodec design enables the hydraulic pressure inside
the bowl to improve scrolling through a narrow opening. Only
the driest fraction of the solids leaves the bowl through the
solids discharge openings into the casing. Separation takes
place throughout the total length of the cylindrical part of the
bowl, and the clarified liquid leaves the bowl by flowing over
adjustable plate dams into the casing.
