A recirculating high pressure lipid extractor includes a kettle with a sealed interior configured for pressurizing and heating a fluid mixture. A flow funnel is positioned in a lower portion. A removable material basket is positioned on top of the flow funnel in an upper section. The removable material basket is configured to hold a material inside the removable material basket. A drain and inlet port is at a bottom of the kettle in communication with the sealed interior of the kettle. A recirculation port is approximate a top of the kettle in communication with the sealed interior of the kettle. Wherein, when the fluid mixture is inserted into the kettle, the recirculating high pressure lipid extractor is configured to pressurize and heat the fluid mixture and recirculate the pressurized and heated fluid mixture from the recirculation port into the drain and inlet port.

Disclosed is a liquid production method and device for producing a liquid containing water-soluble components. The liquid production method includes extracting water-soluble components from a biological tissue, using a liquefied gas, to yield an extraction liquid, and vaporizing the liquefied gas from the extraction liquid obtained in the extracting to concentrate the extraction liquid.

Disclosed herein is a method for obtaining compounds and compositions from plant and fungus materials by thermal treatment, affinity capture, filtration, and release through multi-phasic transitions between gas, solid, and liquid states. The compounds of interest are obtained by manipulating the temperature and pressure of the heating chamber. The compounds in gas phase are passed through an affinity medium which captures the compounds of interest in either solid or liquid phase by exposing the compound of interest to the localized micro-affinity environment of the medium. The compounds are separated from the medium using direct competition with solvent or buffers optimized for the specific chemical properties of compounds.

A filter apparatus includes an elongated housing with a filter input port to the housing and a filter output port to the housing. A mixture flow path is defined within the housing and extends from the filter input port to the filter output port such that the filter input port is in fluid communication with the output port through the mixture flow path. Two or more filter medium receiving volumes are defined within the housing along the mixture flow path, each filter medium receiving volume configured to receive a filter medium and contain the filter medium in the respective filter medium receiving volume. The filter medium receiving volumes are arranged within the housing such that a total length of the filter medium receiving volumes along a housing longitudinal axis is longer than the length of the housing along the housing longitudinal axis defined by the housing.

Described is an extraction device for extracting compounds from plant material and a method for using such an extraction device. The extraction device comprises an extraction tank receiving plant material and dissolving soluble compounds inside the plant material into a solvent to form a micelle. A series of fluidly connected separation chambers separate purified compounds from the micelle, resulting in purified compounds in each of the separation chambers and solvent. A heat exchanger and a chilled reservoir are used for cooling and storing the solvent. A pump is used for pumping and circulating the solvent into the extraction device. Finally, a control system automatically controls temperature and flow in the extraction device.

Devices, systems, and methods are presented that employ high-surface gaseous solvent extraction of terpenoids, essential oil, and/or flavonoids from a liquid raw material at controlled temperature and pressure conditions. In some embodiments, the extraction is based on a rotary or falling film evaporator in which a steam jet is directed at a heated liquid film of raw material at elevated temperatures and reduced pressure.

The present invention pertains in general to an apparatus and method for infusing of a solvent with an infusing material. Embodiments of the invention include applying heat and agitation to the solvent while exposing the infusing material to the solvent for a predetermined time. Upon the end of the infusion process, a removable container can be used to dispense the solvent. Touchless temperature measuring and touchless presence sensing surrounding the removable container allow for the removable container to be placed in the dishwasher when desired.
