Application of spray dryer

Introduction Drying - the process of removing moisture from materials by evaporation and removal of the vapor phase. The drying processes mainly remove moisture bound only mechanically. Moisture evaporates from the surface of the material due to the energy supplied to it by the coolant. Drying is one of the most common and at the same time energy-intensive and expensive methods of preservation, since moisture removal helps to suppress the action of microorganisms, transportation and storage costs are significantly reduced, as the weight and volume of the product are sharply reduced. Milk powder is a soluble powder obtained by drying normalized pasteurized cow's milk. It is usually bred in warm water and consumed as a drink, while preserving all the useful properties of fresh pasteurized milk. It is widely used in cooking. It is part of many types of baby food. The production of milk powder is due to the longer shelf life of the product than conventional milk. Cow's milk is normalized, pasteurized and thickened. Then condensed milk is homogenized and dried on spray or roller dryers. At spray plants, milk is dried at a temperature of 150-180 ° C. Spray dryers are more popular with manufacturers due to their high productivity and constant quality of milk powder.
