Freeze dryer is a technigue that utillizes the principle of sublimation for drying. It makes the dried substance frozen rapidly at low temperatures and then sublimating the frozen water molecules directly into water vapor under suitable vacuum conditions.The substance is always at a low temperature (frozen state) before drying, and ice crystals are evenly distributed in the substance. During the sublimation process, concentration will not occur due to dehydration, and side effects such as foam and oxidation caused by water vapor are avoidedThe dry substance is in the form of a dry sponge with multiple pores, and its volume remains basically unchanged. It is highly soluble in water and returns to its original state.To prevent the physicalchemical, and biological denaturation of dry substances to the greatest extent possible.
For preserving the characteristics of the original substances (e.g.pharmaceutical products or coffee For preserving the original forme.g. animal preparations, archaeological objects, flowers or books) For conditioning the material(e.g. freeze-dried fruit in yoghurt) For the sample preparation for chemical or biochemical analysis(e.g. investigation of trace elements in foods, sludge or soil)
