Freeze Drying Applications

Freeze drying also known as lyophilization or cryodesiccation, is a dehydration process typically use to preserve perishable materials or make the material more convenient for storage.

Freeze drying process removes products moisture by freezing the material, and then reduce the surrounding pressure, proper add heat to allow the frozen water in the material to sublime directly from solid phase to gas.

Because during the dehydration process, materials temperature is always minus. So, freeze drying has less impact on product physical and chemical properties. Which result it works extremely well on almost all industries and fields.

Food Freeze Drying

Freeze drying perfect fit food preservation. Make it light weight, easy storage and transport. With original structure and nutrients are preserved.

Fruit Freeze Drying

Freeze drying is a good way to preserve perishable fruits. Turn them to light weight and easy storage fruit snacks, as well as add value to them.

Dairy Freeze Drying

Freeze drying dairy is nutritional than other dehydration method. Especially for baby milk powder production, freeze drying is highly recommended.

Biological Freeze Drying

Lyophilization or freeze drying is widely used in the preparation of biologicals or bio-pharma. This low temperature drying method improves the storage stability, provides a convenient storage and transport format.

Pharmaceutical Freeze Drying

Freeze drying has been used in many different research and production projects in the pharmaceutical industry. Lyophilization of heat sensitive drugs and biologicals at low temperature, great improve the stability and storage of labile drugs.

Pet Food Freeze Drying

Freeze drying of pet food well keep the protein which guarantees healthy growth of dogs or cats. Frozen pet foods are dehydrated under vacuum environment and minus temperature, which use sublimation technology.

Lab Research

Freeze drying is an ideal way to store samples without being degraded. Microorganism and structure are preserved for deep study.

Advantages of Freeze Drying:

Freeze drying technology used a lot in commercial and industrial areas, the most important advantages of freeze-drying are listed below:

  1. Minimum damage to the material. Specially fit heat sensitive product.
  2. The nutrition, taste, flavor and vitamins are remained.
  3. Keep product original structure. Porous and friable structures is created after water remove.
  4. Fast and complete rehydration guarantee.
  5. Easy storage and long shelf life. Dried product can store at room temperature, no need refrigeration. Shelf life more than 20 years.
  6. Freeze drying material not shrink or toughen.
  7. Freeze drying especially fit product that meets one or more of the following criteria:
    • It is perishable or unstable.
    • It is heat sensitive.
    • Valuable product.
    • Dried product needs quick and complete rehydration.
    • Due to store or transport need, material needs light weight and accept a wide range of storage temperature.
