Concentrated cannabis extract is obtained from raw cannabis plant material using a mixed solvent extraction process. The cannabis is soaked and agitated in a chilled mixture of butane, propane and isobutane. After removing the solid plant material, the remaining solvent mixture, now with dissolved extracts, is heated to remove the solvents. The remaining, viscous oil is then heated in a vacuum oven to purge the traces of solvent and result in a brittle shatter.

Apparatus and methods are provided for extracting compounds from raw materials. One such apparatus may include an extraction column where it is a one column, one pass design capable of withstanding high temperatures and pressure. Additionally, the extraction column may also be capable of containing a self-perpetuating energy cycle used to achieve the required solubilization and mass transfer temperatures necessary for optimal extraction. The apparatus may also include a first opening and a second opening to control the flow of incoming solvent and filter extraneous sediment trapped within the fully extracted effluent. Additionally, the apparatus may be configured to create a self-perpetuating and self-sustaining energy cycle by manipulating the pressure and temperature generated within the apparatus. While the generated temperatures may help achieve a dynamic and efficient extraction process, a trailing cool layer of solvent is also present to effectively preserve the heat sensitive compounds extracted from the raw materials.

A method and apparatus for extracting compounds from raw materials with an extraction column is provided. The control and manipulation of pressure exerted and contained within the extraction vessel or column may be vital in obtaining a certain flavor profile or intensity of the effluent extracted from the raw materials. As such, the method may include directing a flow of pressurized solvent into a base of the extraction column and utilizing the flow of pressurized solvent to create a pressure gradient applied to the raw materials. The method may further include compressing the raw materials with hydraulic compression. As the raw materials become further compressed, frictional heating may result allowing most, if not all, of the volatile aromatic heat sensitive compounds and constituencies to be extracted depending on the pressure strength applied to the raw materials. As such, manipulating the pressure gradients for each extraction process allows for distinct and specific flavor profiles to be extracted from the raw materials.

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.

Disclosed are date palm compositions and methods of use of such compositions. Such compositions may be used as part of a growth medium for culture of microorganisms. In certain embodiments, date palm extracts of the disclosure are used as part a culture medium to grow Lactobacilli.

Embodiments of the present disclosure include a matrix of raw materials that form an interlocking network of varied particle grind sizes that allows the particles to nest and interlock with one another when packed into an extraction vessel, so that most, but not all of the interstitial spacing within the matrix of raw materials is closed. The varied particle sizes may be selected by pre-determined weight ranges and size classifications so that the particle grind sizes achieve the desired consistency uniformity. This may allow the network of particles to act as its own best filtering agent during the extraction process. Moreover, the nesting and interlocking network of the particles within the matrix of raw materials may allow the particles to be effectively packed within the extraction column, thus allowing for an efficient and high quality extraction to be performed consistently each and every time.

Embodiments of an infusion extractor are provided including a plunger to be inserted into an infusing container containing the infusion mixture that can have vertical inner walls oriented parallel to a vertical axis of the container. In some implementations, the plunger includes a first surface with a seal situated at an edge of the surface. The seal is adapted for sealing against the inner walls of the infusing container as the plunger moves within the container. The plunger also includes a second surface extending from the first surface and defining a second chamber. At least a portion of the extract flow openings are situated at a depth either above or below the first surface along the vertical axis.

Embodiments of an liquid filtering device are provided including a plunger to be inserted into an container containing a liquid that can have vertical inner walls oriented parallel to a vertical axis of the container. In some implementations, the plunger includes a first surface with a seal situated at an edge of the surface. The seal is adapted for sealing against the inner walls of the infusing container as the plunger moves within the container. The plunger also includes a second surface extending from the first surface and defining a second chamber.

The system includes an infusion chamber to receive a selected amount of extraction solvent and a sample to be analyzed. The reagents are incubated in the infusion chamber, which is sealed at both ends by rubber stoppers and filter baskets. The reagents are agitated and incubated at the desired temperature for a specified length of time. One end of the infusion chamber is then replaced with a filter-funnel assembly, and a plunger is slidingly received in the opposite end of the infusion chamber to pressurize it and expel the contents of the infusion chamber. The filter-funnel assembly holds back solid matter while allowing the solution to pass through a funnel and either into a spectrometric cuvette. Spectrometry is used to identify compounds, varieties of cannabis, and calculate potencies of edible cannabis-infused products. This system serializes the infusion, extraction, filtration, spectroscopic analysis and can be operated by non-experts.
