Sugar based processing

Alfa Laval has been helping customers in the sugar industry to optimize their processes for many years. Our specialized technologies for sugar-based ethanol production have generations of know-how behind them.

The juice is extracted from sugar beet or cane for fermentation. Alfa Laval WideGap plate heat exchangers are used to remove non-sugars and fibres from the raw juice.


In fermentation, yeast converts sugar to ethanol. Alfa Laval WideGap plate heat exchangers remove the excess heat generated, ensuring fermentation at the ideal temperature. For maximum yield, Alfa Laval disc stack centrifuges separate the yeast from the beer after fermentation. Alfa Laval tank cleaning equipment ensures rapid, reliable cleaning of the fermenter, thus improving both yield and reliability.


Extremely compact heat exchangers from Alfa Laval make installation easier and use space more efficiently. The reboilers make it possible to work with even small small temperature differences that optimize energy efficiency still further by using lower-quality heat sources.

Alfa Laval flexible gasketed heat exchangers are the most durable equipment available for pressure swing dehydration, where fatigue is often a problem.


Alfa Laval plate evaporators provide a compact solution for vinasse concentration. AlfaFlash forced-circulation flash evaporators are used to reach high concentrations in the most energy-efficient way, cutting down on cleaning needs. Alfa Laval membranes are used for polishing evaporation condensate.
