High-performance decanter centrifuge for DDGS production - 1

SG2 decanter centrifuge High-performance decanter centrifuge for DDGS production Application Alfa Laval SG2 decanters provide the most cost-effective, high-performance separation solution currently available for DDGS production. These decanter centrifuges are used to process high throughputs of stillage from all grain types so as to achieving a low level of suspended solids and high cake dryness, with reduced power consumption and lower life cycle costs. Design Alfa Laval designed the SG2 range of decanters with a focus on performance, easy access, reliability and low noise levels. The rotating assembly is supported on a compact, in line, welded box beam frame which includes the both motors for ease of installation, quietness and low vibration. The bowl is driven at the conical end by an electric motor using a V-belt transmission. The bowl, conveyor, casing, inlet tube, outlets and other parts that come into contact with the process media are made of AISI 316 and duplex stainless steel. Parts that are subject to wear are protected with replaceable sintered tungsten carbide or weld applied tungsten carbide. Operating principles Separation takes place in a horizontal cylindrical bowl equipped with a screw conveyor. The product Stillage is fed into the bowl through a stationary inlet tube and is then smoothly accelerated by an inlet rotor. Centrifugal force immediately makes the solids build up on the wall of the bowl. The conveyor rotates in the same direction as the bowl, but at a lower speed, thus moving the solids towards the conical end of the bowl. The solids leave the bowl through the solids discharge openings into the casing. Separation takes place throughout the entire length of the cylindrical part of the bowl, and the clarified liquid leaves the bowl by flowing over adjustable plate dams into the casing.

Direct Drive Direct Drive is a unique system developed by Alfa Laval for automatic control of the differential speed between the bowl and the conveyor. This makes it easy to maintain the best possible balance between liquid clarity and solids dryness, irrespective of variations in the feed. Direct Drive comprises a new type of gearbox and variable frequency drive, which do not expose the bowl drive to parasitic braking power loss. The electrical installation is straightforward, power consumption is kept to a minimum, and accurate control is achieved within a wide range of differentials....
