Milk Powder Drying Process Overview
You should know how the milk powder drying process works before picking a method. Every drying process has its own steps. Each one changes the final product in different ways. These are the main steps in the milk powder drying process:
Raw milk collection makes sure you use good milk.
Pasteurization heats milk to kill bacteria but keeps nutrients.
Standardization changes fat and protein levels for your needs.
Evaporation takes out most water to make the milk thicker.
Spray drying dries milk fast to keep nutrients and stop clumps.
Cooling helps the powder stay fresh and dry.
Sieving and testing check for smooth texture and good quality.
Packaging and storage keep the powder fresh and make it last longer.
Spray Drying
Spray drying is the most used milk powder drying process. You spray thick milk into hot air. The drops dry almost right away. This drying process keeps vitamins and proteins in the powder. Jiangsu Changshi Technology makes spray dryers for high-quality results.
Freeze Drying
Freeze drying uses cold and low pressure to take water out of frozen milk. You get powder with great taste and nutrition. This milk powder drying process is good for products that need gentle care.
Drum Drying
Drum drying puts milk on a hot drum. Water leaves as the drum turns. You get powder with a cooked taste. This drying process is quick and saves money for some uses.
Vacuum Drying
Vacuum drying takes out water at low heat and low pressure. You keep important nutrients and flavors safe. Jiangsu Changshi Technology has vacuum dryers for special milk powder drying process needs.
