Ultrasound-assisted solvent extraction of analytes from porous membrane packed solid samples

A method for extracting an analyte from a solid sample is described. The sample is sealed in a porous membrane bag, which is sonicated in an organic solvent. An extract of the analyte forms in the bag and diffuses into the organic solvent. The organic solvent containing the extract may then be concentrated and analyzed for an analyte with gas chromatography-mass spectrometry. The method does not the use of a solid sorbent material, and does not require a step of centrifuging or filtering.

A powdered, water-soluble Full Spectrum Hemp Oil is formed using organic materials and natural products to form a non-GMO, fast acting, whole plant hemp extract without harsh chemicals such as hexane. The Full Spectrum Hemp Oil may be extracted using CO2 concurrent gas extraction to avoid use of chemical additives.

Systems for extracting solute from a source material

Systems for extracting solute from a source material are shown and described. Each of the systems includes: a solvent source container configured to store a cooled solvent, a canister configured to contain the source material and receive solvent to produce an extract solution, and one or more extract containers in communication configured to receive and distill the extract solution, the solvent source container being configured to receive a post-extraction portion of the solvent. In some examples, the one or more extract containers are first and second extract containers that are each selectively coupleable to the canister and are selectively removable for storage of the extract mixture or the solute. In some other examples, the system further includes a cooling mechanism coupled to the solvent source container for cooling the recycled solvent within the solvent collection container.

20230226461 · 2023-07-20 · ·

Various aspects of this patent document relate to a method to extract an oil from a plant material using an apparatus by first exposing the plant material to a heated gas stream at a temperature sufficient to volatilize the oil from the plant material, and then rapidly cooling the gas stream to liquefy the oil.

Extraction of botanical material using high-pressure hydrocarbons
11559754 · 2023-01-24 · ·

An apparatus and method for extraction of oils from botanical material using high-pressure hydrocarbons such as propane, or butane, or mixtures thereof are described. A high-pressure propane or butane saturated liquid/vapor mixture formed by pressure reduction through a valve placed before an extraction column, thereby serving as an expansion port was employed. The apparatus is capable of both continuous liquid extraction or batch-style liquid operation through the use of a manifold valve, which directs the solvent liquid/vapor in the system to either a supply tank or an extraction column.

OILSEED PROCESSING USING ALCOHOLS OR NONPOLAR SOLVENTS
20230225359 · 2023-07-20 ·

A method of oi seed processing in which an extraction solvent comprising ethyl alcohol is applied in the process of oil extraction. Solvents of similar effect to that of ethyl alcohol may be used in conjunction to produce the desired result. Such a production method yields oil with substantially greater o l stability. As a result of oil extraction and processing, the subsequent meal is of increased palatability for animal and human consumption. Through such extraction and processing methods oil and meal are free of residue and undesirable characteristics commonly associated with other traditional methods of oil extraction.
