Abstract (en)

[origin: US4404038A] To increase the percentage of crystallized lactose obtained from lactoserum substantially without noticeably increasing investment costs or energy consumption, the first phase of crystallization is effectuated in a continuous crystallization stage wherein seeds of crystallization are added to the lactoserum to initiate crystallization, the lactoserum is concentrated, the concentrated lactoserum is brought to a supersaturated state and maintained at this stage by evaporation to obtain a mixture of mother liquor and lactose crystals, which is subjected to two centrifugal drying stages to obtain a first portion of large lactose crystals and a second portion of such crystals grown by cooling.
