Vacuum drying box, as the name suggests, is a kind of instrument that can create a vacuum environment for drying. The traditional drying technology mainly uses high temperature or wind to evaporate or disperse the water, which is time-consuming and laborious and easily damages the product. In contrast, the vacuum drying oven uses low temperature, low pressure and low humidity conditions to not only quickly remove the moisture in the product, but also reduce the generation of harmful gases without causing damage to the product.

So, how does the vacuum drying oven work? Its main principle can be summarized as "dehydration ionization adsorption". In a vacuum environment, the vaporization temperature of water molecules will decrease, so even if the content of water molecules is very low, it can be quickly evaporated. The drying box has a built-in adsorption material, and the surface area of the adsorption material is very large, which can form a large number of micropores and gaps. These spaces can adsorb organic matter, inorganic salts and other harmful gases in water molecules, so that they can precipitate on the adsorption material and play a role in purification. Finally, the drying box is equipped with an ionization gun, and the electron beam will ionize the air molecules near the muzzle. These ionic gases will adsorb on the water molecules on the surface of the product, and make the water molecules evaporate more quickly, with better results. The application of

vacuum drying oven is very extensive, mainly including the following aspects:

1. laboratory: vacuum drying oven is often used in chemical, pharmaceutical, glass and other industries in the laboratory, used to remove the moisture and harmful gases produced in the process of experiment.

2. Manufacturing: Vacuum drying oven is also used in manufacturing, such as food processing, semiconductor manufacturing, electronic devices and other fields, used to remove the moisture and gas inside the product, to ensure the quality and stability of the product.

3. Construction industry: In the production of building materials, vacuum drying boxes are also widely used, such as cement manufacturing, sintered ceramic manufacturing, etc.

4. Automobile manufacturing: The automobile industry also uses vacuum drying ovens to remove moisture and gas from the internal parts of automobiles to ensure product quality and performance.

In general, the principle of vacuum drying oven is simple and easy to understand, but it can produce huge benefits in practical applications. Whether it is laboratory or manufacturing, it is an irreplaceable important tool. We believe that in the near future, its application field will be more extensive.
