How To Get Milk Powder Using A Spray Dryer

The method of spray drying for milk powder The process starts with setting the milk feed into the atomising device of the spray dryer. Atmospheric air is drawn and passes through a filter to the air heater and then to the air dispenser. This hot air hits the atomised droplets in the device and makes them evaporate. The hot air now cools down.

Fundamentals of spray drying

The milk concentrate leaves the atomizing device as a thin film at a velocity of 100 - 200 m/s, breaking up into droplets which immediately contact the hot drying air. Evaporation of most of the water in the droplets takes place during the time the droplets decelerate to reach the velocity of the surrounding gas.

In addition, the feedstock is normally concentrated prior to introduction into the spray dryer.

Fundamentals of spray drying

Two-stage drying involves spray drying to a moisture content which is, for normal milk powders, about 2 - 5% higher than the required final moisture content. Subsequent fluid bed drying then removes the excess of moisture. The outlet temperature from the spray dryer is about 15 - 25C lower than with a single-stage process.
