Large pet food vacuum freeze-drying machine

A large pet food vacuum freeze-drying machine is a processing equipment that transfers heat and mass to freeze-dried materials in a vacuum low-temperature environment. Through vacuum freeze-drying technology, food can be preserved, preserved, dehydrated, and color protected. Any substance that contains water and is non corrosive can be made into freeze-dried products using freeze-drying technology. Almost all agricultural and sideline products such as meat, poultry, eggs, aquatic products, vegetables, etc. can be made into freeze-dried food (FD food freeze-drying). This device is a customized device with a wide variety of types, which can be processed and manufactured according to customer needs.

　　Large pet food vacuum freeze-drying machineThen 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 the molecules is discharged to 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.

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 it is widely used 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, vacuum freeze-drying machines are 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.

1. Easy to store for a long time and convenient for long-distance transportation;

2. Keep fresh and nutritious. Due to production under low temperature and low pressure (hypoxia) conditions, it can effectively prevent the decomposition or oxidation of certain components in the material, as well as inhibit the harmful effects of microorganisms and enzymes, thereby maintaining the freshness and nutritional content of the food;

3. The shape, color, and taste remain unchanged. During the sublimation process, water is gradually removed in a molecular state from the surface to the interior, without damaging the tissue structure or taking away natural pigments and aromatic substances. Therefore, the shape, color, and taste are almost the same as fresh products;

4. Good rehydration ability. During the sublimation process, ice crystals in the food form sponge like micropores, allowing freeze-dried food to quickly absorb water and recover, resembling fresh food;

5. Easy to consume. Due to being washed and cut, and quickly rehydrated, it is extremely convenient to eat or cook directly.
