Claim 11:
12. A method of processing a fibrous cellulosic material, the method comprising:
feeding the fibrous cellulosic material into a chamber, the chamber comprising a shaft having one or more threads disposed circumferentially around the shaft;
rotating the shaft to apply a shear force to the fibrous cellulosic material to increase a pressure of the fibrous cellulosic material inside the chamber;
exposing the fibrous cellulosic material to an environment having a pressure lower than the pressure inside the chamber to induce a cellular explosion in a plurality of cells of the fibrous cellulosic material to generate a liquid extract and a fibrous pulp,
wherein heat from an external source is not injected into the chamber when the shear force is applied.
