The advantages of freeze dryer
Jul 03, 2017

Many heat-sensitive substances do not change or lose their lives.

* When drying at low temperature, the loss of some volatile components in the material is very small.

* In the process of freeze-drying, the growth of microorganisms and the role of enzymes can not be carried out, so as to maintain the original character.

* Due to dry in a frozen state, the volume is virtually unchanged, maintaining the original structure and not concentrating.

* Because the moisture in the material in the form of ice crystals, the original dissolved inorganic salts in water are evenly distributed in the material. Sublimation, dissolve in water dissolved substances on the precipitation, to avoid the general drying method due to the material internal moisture transfer to the surface of the inorganic salts on the surface of the surface hardening phenomenon.
