GZLS Series Vacuum Freeze Dryer (Lyophilizer)
Descriptions
The vacuum freeze drying is an advanced method for the material for
the material dewatering. It freezes the moisture material in the
low temperature and makes the water inside sublimate directly in
the vacuum condition. Then it collects the sublimated vapor by
means of the condensing way so as to dewater and dry the material.
Being processed by the vacuum freeze drying, the physical, chemical
and biological states of the material are basically unchanged. The
volatile and nutritious contents in the material, which are easy to
be denatured in a warm condition, will be lost a little. When the
material is freezing dried, it will be formed into a porous one and
its volume be basically the same to that before drying. Therefore,
the processed material can be recovered quickly if being watered
afghan, because of its large contacting area and it can be stored
for a long period in a sealed vessel.
The vacuum freezing dryer can be widely used for the research and
production of various heat-sensitive biological products such as
vaccine, biological product, medication, vegetable vacuum packing,
snake power, turtle capsule and so on.
With the development of the biological, pharmaceutical, food and
health are product industries; the vacuum freezing dryer is
necessary equipment in the research institutes and companies in
such industries.
