Household food vacuum freeze dryer

application

1. The vacuum freeze dryer is suitable for drying high-end raw materials such as pharmaceuticals, traditional Chinese medicine decoction pieces, seafood, wild vegetables, dehydrated vegetables, food, fruits, and chemical drug intermediates. [1]

2. The vacuum freeze dryer combines the refrigeration system, vacuum system, thermal oil heating system, and dehumidification system into a new type of box structure, which greatly utilizes the storage space inside the box for freeze-drying and vacuum drying, and can make the dried powder have good dispersibility.

Product Features

The process of freeze-drying involves the absence of impurities mixed into the object, which can maintain the original composition, active ingredients, and material form of the material without damage.

working principle

After starting up, put the materials into the material box for freezing The freezing process of materials involves, on one hand, the vacuum system evacuating and removing a portion of the moisture; On the other hand, when the material is frozen, the moisture contained in certain molecules is discharged onto the surface of the material to freeze. After meeting the freezing requirements, the material is heated and dried by the heating system, and the moisture contained in the material is brought to the freezing capture box for freezing by vacuuming, achieving the freeze-drying requirements of the material.

Freeze drying refers to the process of removing water or other solvents from frozen biological products through sublimation. Sublimation refers to the process in which a solvent, such as water, like dry ice, changes from a solid state to a gaseous state without going through a liquid state. The product obtained from freeze-drying is called lyophilizer, and the process is called freeze-drying. Traditional drying can cause material shrinkage and damage cells. The structure of the sample will not be damaged during the freeze-drying process, as the solid components are supported by the solid ice in their positions. When ice sublimates, it leaves pores in the remaining dry material. This preserves the integrity of the biological and chemical structure and activity of the product. In the laboratory, freeze-drying has many different uses and is indispensable in many biochemical and pharmaceutical applications. It is used to obtain biomaterials that can be preserved for a long period of time, such as microbial culture, enzymes, blood, and drugs. In addition to the stability of long-term preservation, it also retains its inherent biological activity and structure. For this purpose, freeze-drying is used to prepare tissue samples for structural studies (such as electron microscopy). Freeze drying is also used in chemical analysis, which can obtain dried samples or concentrate samples to increase analysis sensitivity. Freeze drying stabilizes the composition of the sample without changing its chemical composition, making it an ideal analytical aid. Freeze drying can occur naturally. Under natural circumstances, this process is slow and unpredictable. Through freeze-drying systems, people have improved and subdivided many steps, accelerating this process.
