Spray Dried Milk Powders

Fresh milk is pasteurized and then concentrated by evaporation in vacuum. We then have concentrated whole milk that is dried by atomization, a drying method that allows to transform the liquid milk into powder. Also referred as a dry “spray”. Once the milk is concentrated, it is sprayed into fine droplets from the top of a drying tower, where a stream of air heated to 150°C instantly evaporates the water remaining in the concentrated milk. The obtained powder is then driven to a bag filter that separates the air from the powder before it is packaged in sacks or large bags.
