Description
technical field [0001] The invention relates to the field of drying equipment, in particular to a vacuum stirring dryer. Background technique [0002] The vacuum dryer is specially designed for drying heat-sensitive, easily decomposed and easily oxidized substances, and can be filled with inert gas inside, especially some items with complex components can also be dried quickly. The vacuum dryer is a device that removes moisture from the inner parts of the container by pumping out the air inside the packaging container to reach a predetermined vacuum degree. It is specially designed for drying heat-sensitive, easily decomposed and easily oxidized substances. It can fill the interior with inert gas, especially some ingredients. Intricate items can also be dried quickly. [0003] As a kind of green drying equipment, the market prospect of vacuum dryer is broad. While bringing more benefits and value to the society, it has also achieved a large proportion of the dryer market s...
