A vacuum drying oven is most often used for delicate drying processes such as drying tiny parts or removing flammable solventsThe low pressure environment also minimizes oxidation during dryingA standard vacuum oven can operate at temperatures as high as 200C to 250CA rugged high quality pressure chamber gasket seals and pump are.

A vacuum spray freeze dryer may be used to produce spherical freezedried powders by freezing liquid droplets followed by drying in air under vacuum e−50–60176C and 5–30 PaDrying is rapid due to the large surface area of the frozen material and there is a high uniformity in particle size in the range 100–400 microns that.
