A liquid extractor may include an extraction chamber containing a bed deck configured to support a solid material as the solid material is conveyed through the extraction chamber. To introduce solvent into the solid material being processed, the extractor may include a solvent injection orifice extending through the bed deck and a solvent injector. The solvent injector can receive solvent from a source and cause the solvent to rotate within the solvent injector before discharging the solvent through an outlet in fluid communication with the solvent injection orifice. The rotational flow motion imparted by the injector can create a vortex that functions to scout out any particles that may be present in the injector.

The present disclosure provides an ultrasonic-microwave synergistic extraction method of total saponins in beautiful millettia root, comprising the following steps: S1, material treatment, S2, cold soaking, S3 enzymatic hydrolysis, S4 extract extraction, and S5 ultrasonic-microwave synergistic extraction. The extraction method of the present disclosure extracts relatively high content of total saponins, and has relatively high yield of saponins and low content of impurities, and each step acts synergistically to solve the problems of relatively low total saponin content, more impumayrities and bubbling in the extraction process.

An apparatus and a method for plant extraction are disclosed. The apparatus of the present invention comprises an extraction module, a separating module and a reservoir. The method essentially includes plant material preparing, decarboxylating, active components extracting and separating. By using liquid tetrafluoroethane as the solvent in the apparatus of the present invention, the active components of the plant material are efficiently extracted under low pressure extraction and high pressure extraction conditions.

Disclosed are soluble extractives prepared from non-woody plants of the genus Hesperaloe and processes for preparing the same. The extracts preferably comprise at least one saponin. In certain instances, the process includes providing biomass derived from non-woody plants of the genus Hesperaloe, milling the biomass, washing the biomass with a solvent to yield a crude extract and optionally further purifying the crude extract by filtration to remove water insoluble compositions such as fibers, fines, epidermal debris and lipids. Preferably, the composition extracted from Hesperaloe comprises 25(27)-dehydrofucreastatin, 5(6),25(27)-disdehydroyuccaloiside C, 5(6)-disdehydroyuccaloiside, C, furcreastatin, yuccaloiside, or a mixture thereof.

A feedstock processing system extracts a product from a solid using a CTSE system comprising a plurality of continuous stirred tank extraction stages arranged in fluid communication with each other in series such that effluent from one stage flows to a next stage in the series. One of the stages has an inlet to allow a measured amount of liquid solvent and the solid to be introduced to the continuous stirred tank extraction stage. The stage mixes the solid with the introduced solvent to form a homogeneous slurry to enable the product associated with the solid to be extracted with the solvent. A solid-liquid separator is arranged in fluid communication with the continuous stirred tank extraction stages, and receives an effluent from one of the stages and separates the liquid solvent containing the product from the solid to form a product-containing liquid and a product-depleted solid.

Disclosed are propolis products suitable for use in various industries such as food, health and cosmetics where propolis, which promote various beneficial biological activities in addition to having antimicrobial, antifungal, antiviral, anti-inflammatory, anti-cancer and anesthetic affects, is extracted correctly to offer it a form suitable for human consumption and with the highest bioavailability, where it is fast and easy to consume. Also disclosed is a method of production thereof.

A Cannabis trichome separator. At least one storage vessels are provided, each vessel having an open top and adapted to receive a plant material and chilled or ice water mixture. A mechanism for agitating the mixture is also provided. Another mechanism raises, lowers, and pivots the agitating mechanism, so the agitating mechanism can be placed over the open top of each of the at least one storage vessels. The mixture can be agitated in each of the storage vessels, seriatim. Also disclosed is a method for processing raw plant material. A plant material and chilled or ice water is introduced into each of at least one storage vessels. The agitating mechanism agitates the mixture in a first of the storage vessels, pivoting the agitating mechanism from a first position to a second position, and agitating the mixture in subsequent storage vessels, seriatim.

A method of making CBD concentrate or CBD Isolate comprises (a) milling a raw material; (b) contacting the milled raw material with an extraction solvent and separating a solid waste material to form a filtered extract; (c) concentrating the filtered extract; (d) washing the concentrated extract to form an organic phase and an aqueous phase; (e) separating the aqueous phase from the organic phase to form a washed extract; (f) removing an organic solvent from the washed extract to form a concentrated washed extract; (g) decarboxylating the concentrated washed extract; (h) vacuum distilling the decarboxylated extract to form a distillate; (i) dewaxing the distillate to form a post-dewax filtrate; (j) applying a vacuum to the post-dewax filtrate to form a post-dewax concentrate; (k) degassing the post-dewax concentrate; and (l) vacuum distilling the degassed concentrate to form a CBD concentrate.

A method of producing an extract of an animal-derived or plant-derived biological material includes: extracting a component in the biological material using liquefied dimethyl ether for the biological material to obtain a liquefied dimethyl ether solution including the component; separating the solution from the biological material; and volatilizing or separating the liquefied dimethyl ether from the solution.

A method for extracting compounds from plant material utilizing terpenes as a solvent is described. The invention includes the excitation of the plant material and terpene solvent with microwave, ultrasound, heat input, and physical agitation or combinations thereof. The invention particularly covers the process as it relates to the extraction of THC and CBD 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 or CBD potency, ratios of THC or CBD and their derivatives, or flavor profile.
