摘要： The invention relates to a method for producing whey powder. In this method, whey concentrate with a dry matter content of at least 45% is heated to a temperature of at least 75, and preferably at least 85° C. before, after preliminary crystallization, being dried to a moisture content of at least 9%, in a spray-drying process. The result is a powder with reduced stickiness during drying on account of further crystallization being carried out much more quickly and more completely. The end product obtained is non-caking. The invention also relates to a device for carrying out the method, which also comprises means for treating the discharged drying gases in order to make particles entrained therein less sticky, so that a filter can be used instead of a cyclone.

摘要： The invention provides a spray-drying device comprising a housing (1), a first feed means (2) with a first spray opening, for supplying a first substance, the first substance being a liquid which is sprayed in a cone (3; 3a, 3b) in a first outlet direction, a second feed means (4) for supplying a particle stream (5) in a second outlet direction, the first and second outlet directions including an angle α with respect to one another, and flow-control means for controlling the flow of the liquid and the particle stream, at least one out of the first (2) and second (4) feed means comprising angle-adjustment means (6, 9) for adjusting the angle α, and therefore the overlap and properties of particles or agglomerates formed. The invention also provides a feed means for feeding a material to a spray-drying device according to the invention.
