The vacuum freeze drying equipment 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 dryer, 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 again, because of its large contacting area and it
can be stored for a long period in a sealed vessel.
