Abstract

System and methods are disclosed to process a biomass with a cryogenic fractionator to decimate the biomass into small portions; a holding tank to receive liquid and the small portions of biomass; a cavitator to generate shock waves and pressure variations, wherein the shock waves and pressure variations are to the biomass and the liquid to separate oil from the biomass; a sensor to determine when oil concentration exceeds a threshold; and a valve to transfer the oil and liquid to an oil tank when the threshold is met.

First claim

What is claimed is:

1. A method for extracting oil from a biomass, comprising:
applying a cryogen to a tank to render brittle the biomass;
reducing the cryogenically frozen biomass to small portions;
placing the reduced cryogenically frozen biomass in the tank filled with a liquid;
generating shock waves and pressure variations with cavitation;
applying the shock waves and pressure variations to a mixture formed from the liquid and the reduced cryogenically frozen biomass with oil dissolved or entrained within a fluid of the mixture; and
extracting oil from the fluid.

2. The method of claim 1 , comprising extracting full spectrum tetrahydrocannabinol (THC) or cannabidiol (CBD) from the fluid.

3. The method of claim 1 , comprising detecting elevated temperature in the mixture and applying the cryogen to the liquid to cool the mixture.

4. The method of claim 1 , comprising sensing an oil concentration in the fluid.

5. The method of claim 4 , comprising harvesting the oil once the oil concentration exceeds a threshold.

6. The method of claim 1 , wherein the liquid comprises ethanol, and wherein the extracting oil comprises extracting tetrahydrocannabinol (THC) or cannabidiol (CBD) and cryogenic cooling the mixture with LN2 or CO2.

7. The method of claim 1 , comprising converting a post oil extractions biomass into a bioplastic or a biocomposite material.

8. The method of claim 1 , comprising converting a post oil extraction biomass into a building material.

9. The method of claim 1 , wherein the liquid comprises water or a solvent.

10. The method of claim 1 , wherein after extraction, further comprising:
reducing the biomass into small fragments and extracting oil therefrom with post-extraction biomass;
processing the post-extraction biomass using steam explosion;
treating the post-extraction biomass by dilute acid hydrolysis;
treating unreacted lignocellulostic component of acid hydrolyzed post-extraction biomass by alkaline delignification; and
generating bio-plastic from the post-extraction biomass.
