Liofilizador a Vácuo

This vacuum freeze dryer freezes moisture first, then utilizes the principle of sublimation to remove the moisture from pre-frozen materials without going through the melting process of ice. The moisture is directly sublimated from the frozen state to water vapor, thus achieving the goal of freeze-drying. Compared to traditional drying methods, it has advantages such as preserving the original flavor, Cor, nutrients without loss, and maintaining the original structure.

1. Freeze-drying is conducted at low temperatures, making it particularly suitable for many heat-sensitive substances.
2. Minimal loss of volatile components occurs during low-temperature drying, preserving original nutritional content.
3. Microbial growth and enzymatic activity are inhibited during freeze-drying, thus maintaining the original shape.
4. Drying takes place in the frozen state, resulting in almost no change in volume and maintaining the original structure without concentration.
5. The dried material is porous and spongy, quickly and completely rehydrating upon water addition, almost instantly regaining its original shape.
6. As drying occurs under vacuum conditions with minimal oxygen, it provides protection to substances prone to oxidation.
7. Drying eliminates over 95-99% of water content, allowing dried products to be preserved for extended periods without deterioration.

This vacuum freeze dryers are suitable for drying a variety of materials including active pharmaceutical ingredients, nutritional supplements, fruits, verduras, instant foods, convenience foods, pet food and chemicals.
