Food-focused decanter centrifuge
Application
Alfa Laval Foodec decanter centrifuges are designed for food
and beverage applications. They are ideal for use in the food
industry in situations where the material being processed has
to be separated into a liquid 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 flangemounted
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.
Working 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.
