Learn MoreMilk Powder Freeze Dryer
The Milk Powder Freeze Dryer is designed for premium milk powder and functional dairy products. It is suitable for liquid cow milk, goat milk, formula milk, and high-value dairy formulations. Low-temperature vacuum freeze drying preserves protein structure, milk fat, and active nutrients while enabling stable dehydration and long shelf life at room temperature.
Overview
Dairy products are highly sensitive to heat. Although spray drying is efficient, it often leads to protein denaturation, flavor loss, and nutrient degradation in premium milk powders.
The LONKIA Milk Powder Freeze Dryer uses low-temperature sublimation drying to maintain natural flavor, nutritional activity, and excellent rehydration, making it ideal for premium and functional milk powders.
Working Principle of Industrial Freeze Dryer
The freeze drying process consists of the following stages:
- Pre-freezing Stage: Liquid milk is rapidly frozen to lock in nutrients.
- Primary Drying (Sublimation): Ice sublimates directly into vapor under vacuum.
- Secondary Drying (Desorption): Residual moisture is removed to improve stability.
How to Freeze Dry Milk Powder
- Pre-treat liquid cow milk, goat milk, or formula milk
- Evenly pour milk into freeze drying trays
- Start pre-freezing to lock in nutrients
- Set drying parameters based on milk type
- Mill into powder and package immediately
