Milk powder production involves three primary drying methods: Spray Drying, Drum Drying, and Freeze Drying. Each method plays a crucial role in transforming liquid milk into a long-lasting, nutritious powder.

The Spray Drying process rapidly removes moisture from milk by exposing it to hot air, effectively killing bacteria and evaporating water to produce fine milk particles. Drum Drying offers advantages over other methods by preserving the natural flavor of milk, though it is less commonly used. Freeze Drying, while more complex and costly, delivers the highest quality powder by carefully removing water content through sublimation.

Modern technology has significantly improved milk powder quality, extending its shelf life. The production process begins with collecting raw milk from dairy farms, where it undergoes initial quality checks, including fat concentration, bacterial levels, and cleanliness. The milk is then pre-cleaned, and its fat content is adjusted to meet industry standards.

The milk is heated to around 72°C for 15 to 20 seconds to eliminate harmful bacteria, followed by rapid cooling to prevent bacterial growth. During the evaporation stage, water is extracted using steam, reducing the milk’s mass. The Homogenization process then separates fat molecules, preventing cream formation.

In the Spray Drying stage, milk is sprayed through nozzles into a drying chamber at temperatures between 150°C and 200°C, quickly evaporating water and producing smooth, fine milk powder.

To ensure uniformity, the dried powder undergoes air extraction via a cold Cyclone Separator and is further cooled to maintain quality. Large particles are removed, and the powder is sifted to achieve consistent size. Quality control measures include checking water content, fat, protein levels, and testing for color, taste, and density.

The final product is dehydrated, stored in air-tight containers, and labeled with nutritional information, production date, and expiration date. Proper storage in a cool, dry place away from sunlight ensures the milk powder remains fresh.
