1.- Freeze Drying Equipment Fruit Freeze Drying Machine Strawberry
Freezing DryerFreeze drying is to freeze the water in the
materials into a solid by freezing, and then sublimate the
solid water ice into water vapor by the vacuum and light heating,
so as to achieve the purpose of dehydration.Compared with the
heating drying method, freeze drying has many advantages, such as
low volatile loss, no preservative, keeping the active ingredients
in the material. Therefore, freeze-drying technology is widely used
in pharmaceutical, food, scientific research and other
fields.Generally speaking, freeze-drying machine is mainly composed
of refrigeration system, vacuum system, heating system and control
system.Features & Advantages Of Freeze Drying
Machine:*Protects many heat sensitive substances in the
materials.*When drying at low temperature, the loss of some
volatile components in the materials is very small.*In
the freeze-drying process, the growth of microorganisms and the
role of enzymes can not be carried out.*The volume is almost
unchanged and the original structure is maintained.*The surface
hardening of the material will not be caused because the moisture
in the material exists in the form of ice crystal
after freeze drying.*The materials is loose, porous
and spongy after freezing dried, so can dissolve quickly and
completely, and almost immediately returns to its original
shape.*Since drying is carried out under vacuum, there is little
oxygen, so some easily oxidized substances are protected.*Freeze
drying can remove more than 95% ~ 99% of moisture, so that the
dried products can be preserved for a long time without
deterioration.*Because the material is in the freezing state and
the temperature is very low, so the requirement of heat source is
not high. 2.-Applications of Commercial Fruit Vacuum Freeze
