Dry Milk

Dry milk solids (DMS) are made by removing most (all but about 3–5 percent) of the water from fat-free or whole milk. Most DMS is made by the spray-dry process, in which partly evaporated milk is sprayed as a fine mist into a heated chamber. The milk dries almost instantly and falls to the bottom of the chamber as a powder. Dry milk solids can be purchased as is or “instantized.” Instant dry milk solids are less likely to clump during storage and, more important, dissolve quickly and easily when added to liquids. Instant dry milk solids consist of lighter, larger particles than regular DMS.
