The vacuum dryer itself is specially designed for drying heat-sensitive, easily decomposed and easily oxidized substances. It can be filled with inert gas inside. For example, some items with complex components can also be dried quickly. Then, when drying under low pressure, the oxygen content is very low, which can prevent the oxidative deterioration of the dried material, so it can also dry some flammable and explosive dangerous goods; it can also make the oxygen in the material dry at low temperature. Moisture is vaporized, so that it is easy to dry some heat-sensitive materials; it can also recover valuable and useful components in the dried materials; it can also prevent the discharge of some toxic and harmful substances in the dried materials, making it an environmentally friendly "green" "dry.
