Product features:

- - Sublimation Drying Principle: The freeze-drying process is based on the sublimation principle, where moisture in frozen material directly transforms from ice to vapor without passing through the liquid phase.
  - Preservation of Volatile Components: During low-temperature drying, volatile components within the substance are minimally lost, ensuring the retention of the original composition and structure.
  - Structural Integrity: Freeze-drying allows the material to maintain its original volume and structural integrity, avoiding shrinkage or collapse.
  - Suitable for Temperature-Sensitive Materials: Ideal for biological samples, pharmaceuticals, and foods that are sensitive to heat. This includes items like vaccines, enzymes, fruits, and vegetables.
  - Prevents Oxidation and Degradation: The vacuum environment significantly reduces the chances of oxidation or other degradation processes that can occur during conventional drying methods.
  - Extensive Application: Applicable to a wide variety of products, including biochemical products, pharmaceuticals, and foods. The process is used to preserve the quality of items that would otherwise deteriorate under higher temperatures or during storage.
  - Retention of Original Qualities: By avoiding melting, the freeze-drying method preserves the flavor, color, texture, and nutritional value of food products, and the efficacy of pharmaceutical substances.
  - Minimal Heat Exposure: Materials are dried at low temperatures, reducing the risk of heat damage to sensitive compounds and ensuring the preservation of essential bioactive substances.
