Since commercial available in the late 1800’s, the milk powder production industry has grown significantly, with production of both whole milk powder and skim milk powder.
Milk powder manufacture in its simplest form involves solids concentration of liquid milk usually through evaporation followed by drying and packaging.
The production for whole milk powder generally consists of two stages. In the first stage, milk is condensed to 45-50 percent solids under vacuum in a multieffect evaporator.
In the second stage, the milk are thermal evaporation, homogenization and dried using either spray or roller dryers, which removes all but 4-5 percent of the water content. The resulting powder is whole milk powder.
While, separation of whole milk into cream and skim milk and the subsequent evaporation and drying of the skim milk stream are the primary processing steps used for the manufacture of skim milk powder. Skim powder is also commonly referred to as non-fat dry milk.
Actually there is a variety of milk powders available in the market. Among the dried powder products available are full cream milk powder, skim milk powder, whey and whey protein concentrate powders, milk protein/caseinate powders, buttermilk powders and cream powders.
