New decanter centrifuge enhances Ethanol production

Drawing on 40 years experience as the leading supplier of decanter centrifuges to the UK distillery and US ethanol markets, Alfa Laval has introduced a new generation decanter centrifuge designed for use in high volume ethanol production plants. 

The SG2 700 decanter centrifuge is designed for plants producing roughly 450 million litres of ethanol per year. Its internal design has been optimised for the handling of stillage from grains, such as corn and wheat, from which ethanol is commonly produced. The high “G” forces it generates – up to 3500 G - produce a very dry cake and a thin, very clear stillage liquor.

While the design of the machine focuses on performance and reduced power consumption, it also produces low noise levels for a comfortable work environment. A sturdy welded box beam frame supports the rotating assembly, including the two motors, to ensure low noise and vibration and provide easy access for service and maintenance. As a result, the whole-life costs of the decanter are lower than usual for this type of application.
