The use of a mechanical vapour recompression (energy-saving) evaporator to concentrate acid casein whey
The aim of the energy demonstration project executed at Kantoher Co-operative Creamery is to use a mechanical vapour recompression evaporator instead of a conventional thermal evaporator, to concentrate hydrochloric acid whey from 6 to 32% total solids content. By this concentration, whey, which is a by-product of casein manufacture, is converted into a commercially viable product for animal feeding. Some minor technical problems occurred during start-up and commissioning of the project which have now been rectified. On the basis of 5000 hours per year operation, the energy saving compared to a coventional four-stage evaporator amounts to approximately 600 toe, while the payback time based on overcosts is about two years.
