High Cost Performance Energy Saving and Automatic Vacuum Freeze Drying Equipment For Vegetable
Principle of High Cost Performance Energy Saving and Automatic Vacuum Freeze Drying Equipment For Vegetable
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 High Cost Performance Energy Saving and Automatic Vacuum Freeze Drying Equipment For Vegetable
Advantages of High Cost Performance Energy Saving and Automatic Vacuum Freeze Drying Equipment For Vegetable
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.
