Abstract
Methods for extracting solute from a source material are shown and described. The methods each include: depositing the source material in a canister, introducing a solvent, exposing the source material to the solvent to create an extract mixture, communicating the extract mixture to one or more extract containers, separating the solute from the extract mixture by heating the extract containers, collecting the recycled solvent in a solvent collection container, and cooling the recycled solvent within the solvent collection container. In some examples, the one or more extract containers are first and second extract containers that are each selectively coupleable to the canister and are selectively removable for storage of the extract mixture. In some other examples, cooling the recycled solvent within the solvent collection container is carried out via a cooling mechanism coupled to the solvent storage container.
