Disclosed is an ultrasonic composite acidic water extraction method for a Cordyceps polysaccharide and cordycepin in Cordyceps militaris, which falls within the technical field of food processing. The method comprises: picking, washing, drying, pulverizing and degreasing Cordyceps militaris fruiting bodies to obtain a Cordyceps militaris dry powder; then immersing same in a prepared diluted hydrochloric acid solution to perform three cycles of ultra-low temperature freezing and microwave defrosting, and at the same time using low-frequency ultrasonic waves to carry out assisted stirring and extraction; then subjecting an extract to evaporation and concentration treatments; and finally, performing freeze-drying on the extract to collect a dry powder of a water extraction product. The amount of an additive used in the method meets domestic and foreign usage requirements of food additives, and the operation is simple, practical and uses a combination of chemical and physical methods, thereby saving time and being highly efficient.

A process for the mobilization and extraction of organic matter such as kerogen from solids such as oil shale using ionic liquid. An ionic liquid is a salt in the liquid state which has a melting point below 200° C. The process may be carried out in a subsurface reservoir or at the surface.

Methods and systems for intelligence-driven automation of biomass extraction are disclosed. A controller database may store controller data indicative of reference parameter values associated with functioning of processing chambers of the biomass extraction process, and such parameter values may be associated with obtaining extraction results from a biomass exhibiting certain properties. Real-time sensor data may be obtained from sensors connected to the processing chambers. The sensor data may be compared with the controller data to identify a requirement for altering the parameters. AI algorithms may be used to determine the optimal heating temperature, residence time of the biomass in the reactor, and other settings for other critical parameters of biomass extraction, including stages for biomass processing, decarboxylating, mixing with solvent(s), extraction (with microwave energy), filtering, formulation, etc.

The separation of essential oils from a botanical biomass can be accomplished in a more effective way and with higher yields using microwaves to extract essential oils by dry or azeotropic distillation and isolating products from the essential oils.

A large capacity natural material composition conversion apparatus using a microwave with a preset pressure function includes a chamber including a sealed reaction space accommodating a material, an radiator configured to heat the material by radiating a microwave into the reaction space, a pressure regulator configured to regulate a pressure of the reaction space by supplying a gas into the reaction space, and a controller configured to control the pressure regulator and the radiator, and preliminarily increase a pressure of the reaction space by controlling the pressure regulator before heating the material.

Disclosed is a microwave chemical method for totally extracting fluorine and rare earth from bastnaesite concentrate, including: alkaline conversion defluorination of bastnaesite through microwave irradiation, microwave-assisted leaching of fluorine, solid-liquid separation of leaching solution and microwave-assisted leaching of rare earth. The rare earth hydrochloric acid solution for leaching contains no fluorine ion, so that the fluorine interference of subsequent processes such as impurity removal can be completely avoided; the fluorine and the rare earth are leached with microwaves, which does not need the stirring, so that the automatic control is easy to implement; the fluorine and rare earth leaching speed is high, the leaching time is short and the complete leaching of fluorine and little residual alkali in the slag can be realized by two-time leaching; and no fluorine-containing waste water is discharged, and the total extraction of the rare earth can be realized by one-time leaching.

A process for fractionating a plant material to provide isolated extractives, the process includes pretreating the plant material to provide a fluidized plant material, subjecting the pretreated fluidized plant material to high frequency pulses and shear forces without denaturing bioactive aspects of one or more components of the plant material to provide a first liquid fraction having extractives to be isolated and a first fractionated plant material, separating the first liquid fraction having extractives from the first fractionated plant material, and isolating extractives from the first liquid fraction.

A method for extracting compounds, including stable natural cannabinoid acids, from plant material, utilizing terpenes as a saturant is described. The invention includes the excitation of the plant material and terpene solvent with microwave, ultrasound, sonication, heat input, and physical agitation or combinations thereof. The invention particularly covers the process as it relates to the extraction of THC-A, CBG-A, and CBD-A and their derivatives from cannabis and hemp for the use in products for medical and recreational use. The combinations of terpene saturant, plant material strain and process variables can be tuned in order to dial in the final resultant product for several variables including but not limited to terpene content, THC-A, CBG-A or CBD-A potency, ratios of THC-A, CBD-A, CBG-A and their derivatives, or flavor profile.
