Abstract
Methods for extracting solute from source material, including depositing the source material including solute in canisters, introducing solvent into the canisters, exposing the source materials to the solvents for predetermined periods of time to create extract mixtures including extracted solute and recycled solvent, communicating, fluidly, the extract mixtures to an extract container. Some examples include separating recycled solvent, including heating the container to evaporate the recycled solvent, and collecting the recycled solvent in a solvent collection container in fluid communication with the extract container. Some examples include collecting recycled solvent in solvent collection containers in fluid communication with the extract containers, the recycled solvent being stored as a liquid. Some examples include removably attaching canisters in fluid communication with extract containers.
