FOODEC500 Decanter Centrifuge Application
Foodec500 decanter centrifuge is ideal for use in food industry applications in which the material being processed has to be separated into a liquid and a solid phase. Foodec500 decanter centrifuge comes with two-phase gravity liquid discharge. Foodec500 decanter centrifuge delivers a high extraction yield and a very low solids content in the liquid.
Alfa Laval Foodec500 decanter centrifuge is specially designed for use in food processing applications where hygiene standards are particularly important in order to comply with strict sanitary regulations.
FOODEC500 Decanter Centrifuge Technical data
Bowl diameter: 480mm
Bowl speed: 3650 rpm
Weight: 5000 Kg
Feed temperature range: 0–100°C (32–212°F)
Manufacturing year: 2005
Drive system
The bowl is driven by an electric motor and a V-belt transmission drive. Start method is Direct-On-Line (DOL) using a mechanical clutch. Power is transferred to the conveyor by means of a two-stage planetary gearbox. The speed difference between the bowl and the conveyor is obtained by an efficient back drive system.
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 force 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 Foodec500 decanter centrifuge 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.
