FIELD: food industry.
SUBSTANCE: method envisages growing lactose crystals in condensed whey powder. Crystallisation process proceeds in two stages; at the first stage seed crystals are produced by way of syrup spraying under a 0.087-0.097 MPa depression. At the second stage the produced fine crystals suspension is mixed with the initial syrup in a 1:5-1:10 ratio. Then the produced crystal mass is chilled to a temperature of 10-15°C during 15-20 hours.
EFFECT: increase yield of crystals and process acceleration.
