Processes, methods, and systems for chemo-mechanical cellular explosion and solid and liquid products made by the same
Disclosed herein is a process, comprising combining one or more additives with a feedstock to obtain a first mixture, the feedstock comprising a fibrous material and water, the fibrous material comprising lignin, cellulose, and hemicellulose; and conditioning the first mixture to obtain a liquid product and a dry pulp product. Also disclosed herein are condition processes and machines for use with the same. Also disclosed herein are liquid products, dry pulp products, and fibrous pellets made by the disclosed processes, and methods of using the same.
1. A method of processing a fibrous material, the fibrous material comprising water, the method comprising:
feeding the fibrous material into a chamber, the chamber comprising a shaft having one or more threads disposed circumferentially around the shaft;
applying a shear force to the fibrous material by rotating the shaft, wherein applying the shear force to the fibrous material increases a pressure and temperature of the fibrous material;
inducing a cellular explosion in a plurality of cells of the fibrous 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.
2. The method of claim 1 , wherein inducing the cellular explosion comprises exposing the fibrous material to a decreased pressure relative to a pressure inside the chamber.
3. The method of claim 2 , wherein the decreased pressure is atmospheric pressure.
4. The method of claim 1 , wherein the applying the shear force to the fibrous material comprises removing at least a portion of the water from the fibrous material.
5. The method of claim 1 , wherein the fibrous pulp has a moisture content of between about 10% and 30% by weight without undergoing further drying after the cellular explosion is induced.
6. The method of claim 1 , wherein the fibrous material is derived from wood.
7. The method of claim 6 , wherein the fibrous material comprises wood chips.
8. The method of claim 1 , wherein the chamber further comprises a plurality of shearing members disposed on an inner surface of the chamber.
9. The method of claim 8 , wherein rotation of the shaft applies a shear force to the fibrous material disposed between the plurality of shearing members and the one or more threads.
10. The method of claim 1 , wherein the fiber pulp comprises exposed cellulose fibers.
11. The method of claim 1 , wherein the fibrous material has a moisture content of between 35% and 65% by weight prior to entering the chamber.
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.
13. The method of claim 12 , wherein the fibrous pulp comprises exposes cellulose fibers.
14. The method of claim 12 , wherein the fibrous pulp has a moisture content of between about 10% and 30% by weight without undergoing further drying after the cellular explosion is induced.
15. The method of claim 12 , wherein the fibrous cellulosic material is derived from wood.
16. The method of claim 12 , wherein the chamber further comprises a plurality of shearing members disposed on an inner surface of the chamber, and wherein rotation of the shaft applies a shear force to the fibrous material disposed between the plurality of shearing members and the one or more threads.
17. The method of claim 12 , wherein the fibrous cellulosic material has a moisture content of between 35% and 65% by weight prior to entering the chamber.
