Abstract:
1. A method of extracting a consumable material from a solid raw material comprising acts of: providing a quantity of solid raw material in a surrounding gaseous environment at essentially atmospheric pressure; supplying an aqueous solvent to the quantity of solid raw material in the surrounding gaseous environment at essentially atmospheric pressure, so as to at least partially replace the gaseous environment surrounding the raw material with the aqueous solvent, thereby forming a combination of the solvent and the solid raw material; pressurizing the combination of the solvent and the quantity of solid raw material to a pressure level of at least about 50 psig; exposing the quantity of solid raw material to the pressurized solvent and maintainining the pressure level for a desired period of time under non-flow conditions; and establishing a flow of an aqueous extract from the quantity of solid raw material.
