What is Freeze Dryer?

The freeze dryer (lyophilizer or freeze dryer) originated from the vacuum freeze-drying technology in the 1820s. It refers to a process in which solid materials are directly sublimated into a gaseous state under vacuum conditions without going through the liquid phase. During the freeze-drying process, the original chemical structure and morphology of the solute will not be destroyed. In addition, the biologically active material can still restore the conformation and biological function before freeze-drying after being re-dissolved. Compared with other drying methods, vacuum freeze-drying technology has incomparable advantages, so this technology is increasingly widely used in biology, medicine, food, environment, etc.

Features of Freeze Dryer

  1. Heat-sensitive substances will not be denatured or inactivated.
  2. Greatly reduce the loss of some volatile components in the substance.
  3. The growth of microorganisms and the action of enzymes are eliminated, so the original characteristics can be maintained.
  4. Keep the original structure without concentration.
  5. Avoid surface hardening caused by general drying methods.
  6. The product can be stored for a long time without deterioration.
  7. Each model is available in 4 types: Ordinary, Top-Press, Ordinary Multi-Manifolds, and Top-Press Multi-Manifolds.
