Principle of FD Multifunctional Vacuum Freeze Drying Machine/Food Freeze Dryer Machine

After startup, put the materials into the material box for freezing The freezing process of materials On the one hand, the vacuum system vacuumizes and takes away part of the water; On the other hand, when the material is frozen, the water contained in some molecules is discharged to the surface of the material for freezing After the freezing requirements are met, the material is heated and dried by the heating system, and the water contained in the material is brought to the freezing capture tank for freezing by vacuuming to meet the requirements of material freeze-drying.

Freeze drying refers to the process of removing water or other
solvents from frozen biological products by sublimation.
Sublimation refers to the process in which a solvent, such as
water, like dry ice, changes directly from a solid state to a
gaseous state without going through a liquid state. The product
obtained by freeze-drying is called lyophilizer, and this process
is called lyophilization.

Traditional drying will cause material shrinkage and destroy cells.
During freeze-drying, the structure of the sample will not be
damaged because the solid components are supported by solid ice in
its position. When ice sublimates, it leaves pores in the dry
residual material. In this way, the integrity of the biological and
chemical structure and activity of the product are retained.

Application of FD Multifunctional Vacuum Freeze Drying Machine/Food Freeze Dryer Machine

Advantages of FD Multifunctional Vacuum Freeze Drying Machine/Food Freeze Dryer Machine

1, Freeze drying is carried out at low temperature, so it is especially suitable for many heat sensitive substances For example, proteins and microorganisms will not denature or lose biological vitality Therefore, it is widely used in medicine.

2, When drying at low temperature, the loss of some volatile
components in the material is very small, which is suitable for the
drying of some chemical products, drugs and food.

3, In the freeze - drying process, the growth of microorganisms and
the action of enzymes cannot be carried out, so the original sex
suit can be maintained.

4, Because it is dried in the frozen state, the volume is almost
unchanged, the original structure is maintained, and the
concentration phenomenon will not occur.

5, The dried material is loose, porous and spongy. It dissolves
rapidly and completely after adding water, and almost immediately
restores its original properties.

6, Since drying is carried out under vacuum and there is little
oxygen, some easily oxidized substances are protected.

7, Drying can remove more than 95-99% water, so that the dried
products can be preserved for a long time without deterioration.

Therefore, freeze drying is widely used in pharmaceutical industry,
food industry, scientific research and other departments
