Abstract
A closed rotatable extraction system includes at least two tubes where one tube accepts an extractable material, and the system can be evacuated through a valve in the system. At least one conduit comprises at least one flexible hose, bent ridged pipe, t-pipe, curved pipe, or any combination thereof. At least one valve that when open allows evacuation of the system, and optionally for introduction of a solvent for extraction. When the at least one valve is closed a solvent vapor atmosphere is defined as almost exclusively or exclusively the solvent vapor and has a gas pressure that is about the solvents vapor pressure or less in the closed rotatable extraction system. The closed rotatable extraction system or a portion thereof can involve a first rotation orientation for liquid transfer and a second orientation for a vapor transfer.
