Methods to produce a spray-dried active tetrahydrocannabinol powder and/or cannabidiol powder are described. The methods include introducing a heated gas and a liquid mixture of water and active tetrahydrocannabinol and/or cannabidiol into a spray dryer and then separating powder from the spray-dryer in a two-step separation process. Counter-current spray dryers and co-current spray dryers are described followed by separation of the powders with a cyclone, filter, electrostatic precipitator, or sifter.

A water based distillation equipment includes a lower boiling vessel for containing plant material and water/steam, and having an open top portion; a heat source for heating the plant material within the lower boiling vessel; and a condenser mechanically connected to the lower boiling vessel so as to cover the open top portion of the lower boiling vessel; and a collection vessel connected to the distillation equipment. The inside walls of the condenser include gutters for collecting hydrolate and condensate within the distillation equipment, and the collection vessel is coupled to the gutters for receiving the collected condensate. The surface area of the condenser is at least about 1.5 times a surface area of the lower boiling vessel.

The present patent application relates to a compact device with a modular design, and to a method for extracting volatile oils and herbal distillates contained in organic matter, using the extraction technique of steam distillation. The device is formed by a lower cylindrical module on top of which an upper hemispherical module may be disposed, and both modules may be secured to form a single hermetic body. The lower module may contain a hot-water boiler, a heat conducting disc, a steam-heating chamber, a still of raw material, and a valve for regulating the steam flow. The upper module may contain a conical steam condenser, a hemispherical cover, a ring for collecting distilled liquid, and a tube for removing the distilled liquid. The distillation method of internal steam distillation may integrate, in a single physical body, a semi-closed steam flow circuit that may include all the functions of distillation.

A continuous distillation process comprises the following steps: putting a material into a multilayer distillation tower to enable the material to sequentially undergo preheating, extrusion pricking, steam distillation, meal roasting, drying and cooling treatment, condensing essential oil-containing steam, and carrying out water separation, so as to obtain an essential oil.

A plant extract can be produced from a plant material, such as a cannabis plant material, via an ambient temperature distillation followed by a cold trap condensation. The cold trap apparatus has at least one sealable chamber under vacuum connected to a condenser for extracting chemical compositions at an unelevated temperature from a plant material. Desirable chemicals can be volatilized under negative pressure at low temperatures utilizing the cold trap system described herein.

A multi-functional distiller for separating target compounds from a base material. The distiller has a basket, boiling tank, and sealable cap. The basket has at least one selectively sealable port for holding the base material. The boiling tank is adapted for containing a solvent, and the basket is attachable above the solvent. The sealable cap may be removeably attachable to the boiling tank to provide a sealed chamber. The sealable cap can be fitted with multiple condensers. One possible condenser is positionable exterior to the boiling tank and functions to condense vapors produced by the boiling tank. A second such condenser is an inverted condenser which is positionable interior to the tank so as to condense vapors produced by the boiling tank and cause the condensate to drip through the base material.

A process and system to extract essential oil from a material is described. The process includes expressing the essential oil into water to form a fluid mixture that contains essential oil, an essential oil-water emulsion, and water; heating the fluid mixture to destabilize the essential oil-water emulsion and separating the heated fluid mixture into a waste mixture and a product fluid mixture, where the concentration of essential oil in the product fluid mixture is greater than the concentration of essential oil in the fluid mixture.

A hybrid mint plant characterized by an essential oil composition profile, methods of cultivating the hybrid mint plant, and methods of producing an essential oil composition with the essential oil composition profile using the hybrid mint plant are disclosed.
