Whey waste recycling unit

Nowadays the processing technology of whey is being mastered for obtainment of high added value products, e.g. whey protein. During the processing of whey, as a side product accrues whey lactose. The utilization of this product, without polluting the environment, is problematic. Therefore this unresolved issue allows developing technology of whey processing with sufficient profitableness. Latvian company BALTIC DAIRY BOARD in year 2015 launched factory of whey processing and department of lactose processing. The company along with biotechnologists of Latvia, developed bioprocess for various whey, as well as whey lactose processing, where used yeast strains could efficiently uptake lactose as a substrate. As a result, yeasts for food industry were obtained. The given technology is successfully introduced in practice, and as the experts of the field admits, it is unique and gives an opportunity to obtain high added value product. For the run of production fermentation process, technological line is used. It consists of bioreactors with volume of 35, 350, 4000 liters and two bioreactors with volume of 15 000 l. In all bioreactors, a novel type magnetic mixer (even in 15 000 liter bioreactor!) was used. Above mentioned system is fully closed and automated, the connections between bioreactors are provided by pipeline system and 4 membrane valve group. The system with membrane valve group provides sterile nutrition media and product transport, as well as pipeline and reactor cleaning and sterilizing. ​
