As an ancient country with agricultural civilization, people's lives are inextricably linked with food. In particular, with the continuous development of social development and productivity, food has gradually become surplus. The subject of slow food preservation and preservation has been placed in front of people. Through continuous exploration and discovery, humans have invented methods for preservation and dehydration, freeze-drying, canning, and chemical preparations. Drying is one of the ways to keep the material from spoilage. There are many ways to dry, such as drying, boiling, drying, spray drying and vacuum drying. However, these drying methods are performed at a temperature of 0° C. or higher. The resulting dried product is generally reduced in size and hardened. Some substances are oxidized, and some of the volatile components are lost. Drying can cause the material to shrink and damage cells. The structure of the sample will not be destroyed during freeze-drying because the solid component is supported by the hard ice in its place. When ice sublimates, it leaves pores in the dry residue. This preserves the biological and chemical structure of the product and the integrity of its activity. The freeze-drying method is different from the above drying method. The drying of the product is basically performed at a temperature of 0° C. or lower, that is, the product is frozen until the later stage, in order to further reduce the residual moisture content of the product, the product is allowed to rise to Temperature above 0°C. Freezing and vacuum drying process is to mix all objects into pure object, which can keep the original ingredients and active ingredients and material form of the material from being damaged. Using the principle of vacuum freeze-drying, it has compact and reasonable structure, convenient maintenance, low cost, automatic control and easy operation. In the laboratory, lyophilization has many different uses and it is indispensable in many biochemical and pharmaceutical applications. It is used to obtain biological materials that can be stored for a long period of time, such as microbial cultures, enzymes, blood, and pharmaceuticals. In addition to its long-term stability, it retains its inherent biological activity and structure. For this purpose, lyophilization was used to prepare tissue samples for structural studies (e.g. electron microscopy studies). Freeze-drying is also used in chemical analysis, it can get a dry sample, or concentrate the sample to increase analytical sensitivity. Freeze-drying makes the sample components stable without changing the chemical composition, and is an ideal analytical aid. Quanshi Food Machinery (Shanghai) Co., Ltd. is a professional science and technology development enterprise integrating research and development, manufacturing, installation, debugging and training. It has successively cooperated with foreign counterparts, introduced advanced technologies, and continuously innovated and digested foreign products. The advanced design and manufacturing technology have produced a batch of vacuum freeze dryers with progressive processes and high quality. Quanshi Vacuum Freeze Dryer Quanshi vacuum freeze-drying machine is suitable for the drying of materials such as high-grade raw materials, Chinese herbal medicines, biological, wild vegetables, dehydrated vegetables, food, fruits, chemicals, and pharmaceutical intermediates. The vacuum freeze dryer combines the refrigeration system, the vacuum system, the heat transfer oil heating system, and the dehumidification system, and introduces a new type of box structure, which uses the storage space of the box to dry it. specification: After starting up, the materials are put into the material box for freezing. The freezing process of the materials: on the one hand, a vacuum is used to pull a part of the water away; on the other hand, when the material is frozen, the moisture contained in some molecules is discharged. The surface of the material is frozen. After reaching the freezing requirement, the material is heated and dried by the heating system, and the water contained in the material is brought into the freezing trap box by vacuum to freeze the material to achieve the requirements of freeze drying of the material. The whole style Quanshi Food Machinery (Shanghai) Co., Ltd. is a professional technology development enterprise integrating scientific research and development, manufacturing, installation, debugging and training. It specializes in vacuum frying machines (low temperature vacuum frying machines) and roof box irrigation. Installed machine, automatic roof box packaging machine, semi-automatic roof type packaging machine, roof type carton filling machine, Tetra Pak aseptic packaging machine, juice beverage production line equipment and other fluid food production lines, bioengineering design, manufacture, installation, etc. Turnkey projects.
