Vacuum freeze drying is the removal of water or other solvents from the
frozen samples. During the whole drying
process, the sample is in a liquid state and the temperature is
generally lower than -10℃. The purpose
of vacuum freeze drying is to restore the original
characteristics of the sample after rehydration. Because the drying process is carried out at low temperature, it can be
used for some materials such as proteins which are easily
denatured
at high temperature, and the dryer can ensure that the properties of other
compounds will not change. Most of the biological products will
be changed into dry samples by vacuum
freeze-drying. Vacuum freeze drying is the most gentle process to preserve the biochemical properties of sensitive tissue or
other tissue. It is also the best method for drying inorganic materials, such as nano
particles, because the surface areas of particles are almost
unchanged.

How it works:
|
|
Vacuum freeze-drying
is one of the most gentle ways to dry. It is based on the
sublimation principle, that is, the physical phenomenon of
directly converting the solid phase into the gas phase
occurs. The
to-be-processed is placed in a vacuum drying chamber for
drying, and the water vapor produced by the cold trap is condensed
to form ice, so as to achieve the purpose of eliminating water
vapor. Vacuum pump is used to discharge the air in the drying room, not
including water vapor. The baffle plate is provided with a heating device, and the heat is
transferred to the material through the conduction function to
provide the needed energy for sublimation. When the free water in the material is sublimated, the internal
bound water can also be removed from the material at a very low
vacuum. This drying process is considered to be the last stage of drying,
and analytical drying.

Warning：
|
|
1. Paper,
cloth, or similar materials do not near the gas circulation
pathway , otherwise heat exchange may be blocked.
2. Freeze dryer should be placed horizontally,
and the ambient temperature
is about+10℃~32℃.
3. The clearance between dryer and wall should be more than 40cm, to
keep enough airflow. Never near the heater or other heat source. Never be in sunlight
directly.
4. The
lack of air circulation or the high ambient temperature can
cause the phenomena that the pressure or temperature of the
refrigeration system is higher and is even larger than the
allowable operating pressure or temperature, and the failure
will occur.
