A plant oil extractor includes a food grade tray with a removable lid that together define an evaporation chamber. A gaseous fluid pump has an inlet fluidly connected to the evaporation chamber and an outlet fluidly connected to an area outside of the evaporation chamber, which may be positioned in a freezer to recover condensed solvent leaving previously dissolved plant essential oil on the food grade tray. A vacuum sublimation freeze drying apparatus includes a container, which defines a drying chamber, is positioned in a freezer. A gaseous fluid pump has an inlet fluidly connected to the drying chamber and an outlet that opens outside the container.
