Principle of Freeze-Drying
Drying is one method of preserving substances from spoilage and deterioration. There are many ways to achieve dryness, such as sun-drying, boiling dry, air-drying, spray drying, and vacuum drying, among others. However, these drying methods are all based onPerform at temperatures of 0℃ or higher. The dried product is generally reduced in volume, harder in texture, with some substances oxidized, and most volatile components lost. Heat-sensitive substances, such as proteins, may denature. Microorganisms lose their biological activity, and the dried material is not easily soluble in water. Consequently, there are significant differences in the properties of the dried product compared to the original, and the freeze-drying process differs from the above drying methods. The drying is carried out primarily at temperatures below 0℃, i.e., while the product is frozen, until the later stage when the product is raised to temperatures above 0℃ to further reduce the residual moisture content, but usually not exceeding 50℃. Freeze-drying involves pre-freezing a substance with a high water content into a solid, then evaporating the water vapor directly under vacuum, leaving the substance behind in the ice framework. Thus, the dried product is loose and porous with unchanged volume. To decrease the product's temperature and slow the sublimation rate, heating is necessary to increase the sublimation speed and shorten the drying time. The entire drying process is conducted at lower temperatures.
The Advantages of Freeze-Drying
1. Freeze-drying is conducted at low temperatures, making it particularly suitable for many heat-sensitive substances, such as proteins and microorganisms, which do not denature or lose their biological activity. Therefore, it is ideal for...MedicineWidely applied.
2. During low-temperature dry roasting, the loss of volatile components in the substance is minimal, making it suitable for drying certain chemical products, pharmaceuticals, and foodstuffs.
3. During the freeze-drying process, the growth of microorganisms and the action of enzymes are inhibited, thereby preserving the original characteristics.
4. Due to drying in a frozen state, the volume remains almost unchanged, preserving the original structure without any concentration.
5. The dried substance is loose and porous, resembling a sponge, dissolves quickly and completely in water, and almost immediately returns to its original properties.
6. Due to the drying process being conducted under vacuum, where oxygen levels are low, some easily oxidizable substances are thus protected.
7. Drying can remove over 95% of the moisture, ensuring the product can be stored long-term after drying without spoilage.
Therefore, freeze-drying is currently in the medical field...StudyIndustrial, food industry, scientific research, and other departments enjoy wide applications.
