Food-focused decanter centrifuge
Application
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.
Benefits
• cost-effective performance
• continuous operation
• compact, modular design
• Plug & play unit with Direct-On-Line (DOL) start method.
Standard design
Alfa Laval designed the Foodec decanter centrifuge with a focus
on hygiene, easy access, reliability 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 designed to
ensure easy access. The in-line motor is flange-mounted on the
decanter, with adjustable brackets for belt tension adjustment.
The bowl is driven at the conical end by an electric motor
and V-belt transmission. Bowl, conveyor, casing, inlet tube,
outlets and other parts in contact with the process media
are made from stainless steel AISI 316.
Operating principle
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.
