In order to extend its portfolio, Moravia Lacto has decided to buy the electrodialysis technology to produce demineralized whey powder from sweet and acid whey. The RALEX® EWDU technology by MEGA allows flexibility in processed volumes, a variation of feed including acid whey and different demineralization rates.
A system of four 25-ton batches of whey and one cleaning process within a 24-hour cycle has been chosen. The demineralization of smaller quantities would be feasible, but not economical.
Electrodialysis was chosen due to its highly efficient separation and purification with low operating costs. The demineralization plant has been running since 2009 with extension in 2012 and an upgrade in 2016.
This project allows to internally reuse dairy by-products in the food industry and make milk processing a waste-free production. The new production site is so effective, that it processes not only its own whey, but also whey from other factories in the surrounding regions in Belarus. The whey is processed into two main outputs. Demineralized whey powder for the food industry and high quality demineralized whey fat concentrate for livestock feeding. The MEGA technology is universal and can be set to produce LD50, SD70 or SD90.
The Demineralized whey powder is requested in Russia, China, India and South-East Asia, which gives Milkavita new export opportunities.
