Overhaul: GEA decreases Unilever’s energy consumption

GEA Wiegand says it has helped to streamline the production processes of one the world’s most beloved products—Marmite. Autolyzed brewer’s yeast extract had previously been concentrated from 6 to 45 % TS using two steam-heated, 3- and 5-effect evaporators—one of which was originally supplied by GEA Wiegand in 1957! So the company replaced these with single effect evaporators which use mechanical vapor-recompression technology to recycle flashed vapors to reduce energy costs.
