A method for extracting an essence or perfume oil from pistachio hulls, the method comprises separating the pistachio green hulls or velvet hulls from pistachio nuts using an industrial separator and subjecting the hulls to an extraction method, which causes release of the essence from essence containing glands, wherein the essence mixes with steam forming vapors. The method further comprises distilling the vapors to form a liquid comprising the essence mixed with an aqueous component and separating the essence from the aqueous component. Compositions and methods for extracting perfume oil from pistachio hulls are described.

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.

A pet toy infusing device includes a base, a removeable cover and a porous insert. The base includes a cavity, and has an opening configured to enable access to the cavity. The removable cover is configured to cover the cavity. The porous insert is removably disposed inside of the cavity between the base and the cover, the porous insert having an interior surface defining a pet toy holding area, and being configured to prevent a material disposed inside the cavity of the base from entering the pet toy holding area, while enabling a pet toy disposed in the pet toy holding area to be infused with the material.

The invention provides systems and methods for the automation of the extraction of a liquid substance from a material. The disclosed systems include multiple tanks and valves under computer control providing for the safe transport of a solvent through the material under computer control. Solvent transport is accomplished by heating and/or cooling selected tanks or vessels to cause the solvent to evaporate or condense as desired. Tank and/or solvent heating and cooling is controlled automatically. Thus, in all embodiments the use of external pumps can be avoided.

The present invention relates to the development of high viridiflorol containing variety for enhancing the aroma as well as medicinal properties of Mentha piperita by overexpressing MPTPS4 gene through genetic transformation. This transgenic plant possesses better growth and able to produce essential oil with good quality contains high viridiflorol maximum of about 25% and proportionate decrease in menthone, menthofuran and menthol of Mentha piperita as compared to other control genotype. Mentha piperita (CIM-madhuras) that produces viridiflorol, a molecule of potential demand in perfumery, cosmetics, toiletries, drugs and sanitation products.

A two stage system for extraction of oil from whole citrus fruit is provided. The first stage is known in the art and includes a first plurality of toothed rollers which convey citrus as the teeth penetrate and rupture oil glands. The oil passes into a first water pan. A novel second stage uses a second plurality of toothed rollers to continue the penetration and rupturing of oil glands. The second plurality of rollers are positioned in an isolated second pan to partially submerge the citrus. A middle phase liquor with extremely low oil concentration is transferred into said second pan to initiate desorption of oil from the citrus. The desorption technique in one embodiment increases yield by 4% or more. This technique is expected to increase yield even more as the recovery by the first stage is reduced.

A system for processing essential oils includes a mixing tank, three winterization vessels, three respective filtering vessels, a fine filtering vessel, a holding tank, an evaporator, an essential oil reservoir, a solvent reservoir, and a solvent filtering vessel. The evaporator can include a heat exchanger configured to heat a plate down which a mixture including the oils flows, to evaporate other components of the mixture. Fluids can be advanced through the system using a pressurized inert gas.

The present invention relates to an extraction apparatus for extracting at least one constituent in a substance. The extraction apparatus comprises an extractor, an extraction separator and an extraction condenser. The extractor is used to mix the substance and an extraction fluid, wherein the extraction fluid is a subcritical fluid. The extraction separator is connected to the extractor for receiving and heating the extraction fluid to gasify the extraction fluid and to separate the constituent and the gasified extraction fluid. The extraction condenser is connected to the extraction separator and the extractor for receiving and liquefying the gasified extraction fluid from the extraction separator and sending the liquefied extraction fluid to the extractor.
