Freeze dryer freezes samples including aqueous solution or water at least below -40°C, reduces the water vapor pressure of the temperature and sublimates and dries ice.
Freeze drying occurs at low temperature, so samples are not deteriorated well by heat. After drying, samples are resolvable well, so it is appropriate for the concentration of aqueous solution.
Original characteristics of samples such as taste, flavor, shape or substances are mostly remained after drying with this method.
Therefore, with freeze drying, samples which have unstable biological activities in moisture condition or aqueous solution can be preserved for a long time.
