Freeze Drying or Lyophilization is a such a dehydration process in which is water is removed for the frozen sample using purified vacuum condition. This process is followed by first stage Sublimation (primary drying) and last stage Desorption (secondary drying). In lyophilization process, where water in ice form on the frozen goods can be directly lyophilized into steam without melting in advance, thus the goods are dried. The substances frozen can be well-preserved for a long time and returned to their former state once being watered without losing their biochemical properties. The freeze drying technology is especially ideal for those bio-products sensitive to antibiotic, vaccines, blood products, enzymes and hormones.
