With the development of society, people are paying more and more attention to their physical health. While strengthening exercise, there is an increasing demand for natural, safe, and nutritious food. The Shanghai Yetuo Laboratory freeze dryer has become one of the important laboratory equipment, helping researchers in the research and development of food freeze drying.
Advantages of Freeze Drying Technology
1. Freeze drying is carried out at low temperatures to fully retain nutrients, making it particularly suitable for many thermosensitive substances. Some volatile components in the substance are lost very little, making it more suitable for food drying and fully preserving the original nutrients.
2. Eliminating the denaturation of existing substances during freeze-drying prevents the growth of microorganisms and the action of enzymes, thus maintaining their original characteristics.
3. Preserving the appearance of fresh products, due to drying in a frozen state, the volume remains almost unchanged, maintaining the original structure and preventing concentration.
4. Strong rehydration ability, similar to the dried substance of fresh products, dissolves quickly and completely after adding water, almost immediately restoring its original appearance.
5. Vacuum drying prevents oxidation. Due to the fact that drying is carried out under vacuum with very little oxygen, some easily oxidizable substances are protected.
6. The ultra-low moisture and non perishable freeze-drying technology can remove over 95-99% of moisture, allowing the dried product to be stored for a long time without spoilage.
The Shanghai Yetuo Laboratory freeze-drying machine is based on vacuum freeze-drying technology, which freezes water containing food substances into solid state at low temperature, and then sublimates and dries them under high vacuum state. The solid ice in the food is directly sublimated into gas without liquid to remove it, resulting in freeze-dried food with very little water content.
The quality of the freeze-drying machine in Shanghai Yetuo Laboratory directly affects the accuracy and reliability of scientific research experiments, and has a significant impact on later production and processing. Therefore, choosing a high-quality Shanghai Yetuo Laboratory freeze-drying machine is the standard for rigorous scientific experimental research and development.
