Method for producing crystallized lactose from whey and / or milk permeate, crystalline lactose and apparatus for producing crystalline lactose

Abstract

The invention relates to a process for producing crystallized lactose from whey and / or milk permeate, wherein, during the filling of whey and / or milk permeate into a crystallization tank, the filled whey and / or milk permeate is cooled by means of a cooling device comprising an indirect heat exchanger in the bypass line by conveying the conveyed whey and / or milk permeate from the crystallization tank via a bypass line, so that crystal nuclei are formed by crystallizing lactose, and crystal growth occurs by supplying further whey and / or milk permeate via a subsequent permeate inlet in the bypass line. The mixture is returned to the crystallization tank via a mixing and residence section of the bypass line and cooled. The invention further relates to crystalline lactose and a device for producing crystalline lactose from whey and / or milk permeate.
