Spray dryer machine for milk powder | Industrial centrifugal spray dryer | Food GMP certification

Spray dryer machine is the key equipment in the production of milk powder. Through the continuous process of atomization+hot air drying, liquid milk, whey, milk slurry and other raw materials are directly transformed into high-quality powder. Compared with traditional drying methods, spray drying has obvious advantages such as fast drying speed, high nutrient retention rate, good product liquidity, etc., and has become the mainstream choice of the global milk powder industry.

Industrial grade spray drying equipment specially designed for heat sensitive materials such as milk powder, milk powder, whey protein powder, etc., uses high-speed centrifugal atomization technology to complete the transformation of liquid milk into powder within 10-30 seconds, retain the nutritive active ingredients to the maximum extent, meet the GMP food level health standards, support the nitrogen closed circulation oxidation prevention process, and is the core equipment of modern milk powder production line.

Working principle

The process of Spray dryer machine for milk powder can be simply understood as "spraying milk into fog and drying it with hot air", which can be divided into four steps:

Step 1 ️：Material liquid transportation

After filtration, homogenization, and preheating, liquid milk is stably fed into the atomization system by the feed pump. For high viscosity materials, the equipment is equipped with mixing and preheating functions to prevent blockage.

Step 2 ️：High speed atomization (most critical)

The liquid enters the high-speed rotating centrifugal atomization disc and is thrown into micrometer sized droplets (diameter 10-100 μ m) under the action of centrifugal force, forming a huge surface area and creating conditions for rapid drying.

Step 3 ️：Instantly dry

Clean hot air (usually with an inlet temperature of 150-200 ℃ and an outlet temperature of 80-100 ℃) enters uniformly from the top of the tower and comes into contact with the mist droplets. Water evaporates rapidly within 10-30 seconds, and the droplets directly turn into dry powder particles.

Step 4 ️：Gas solid separation and collection

The dried powder enters the cyclone separator and bag filter with the airflow to achieve powder gas separation. The finished product is collected from the bottom of the tower and the separator, and the exhaust gas is discharged or circulated through the induced draft fan.

Why should milk powder be dried with spray?

Because the protein, vitamins, and other nutrients in milk powder are sensitive to heat, traditional drying takes several hours, which can lead to nutrient loss. Spray drying only takes tens of seconds to retain the active ingredients to the greatest extent.
