Foodec 800 - Alfa Laval - #1

Text version of the page

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. 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. Food-focused decanter centrifuge Foodec 800 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.
