Abstract (en)
[origin: WO2015121238A1] For continuous production of qualitatively high-grade lactose monohydrate crystals from a solution, the invention proposes the preparation of a highly concentrated solution in a falling film evaporator (1), from the pre-concentrated solution (L2), which is then subjected to continuous cold crystallization (2) with forced circulation (KR) and from which a lactose suspension (SP) is drawn off that forms the product crystals following separation of the transported solution. The product crystals (K) are thereby obtained directly by solid/liquid separation (3), without further crystallization steps from the suspension that was drawn off from the cold crystallization (2). A portion of the mother solution separated off from the product crystals (K) is fed back to a point prior to the inlet to the falling film evaporator (1), the remainder of the mother solution (A) is discarded.
