The present disclosure relates to isolating one or more cannabinoids from an input mixture. There is disclosed an apparatus that comprises a volatizing unit, a fractional distillation unit, and a condensing unit. The volatizing unit receives and volatilizes the input mixture to provide a cannabinoid-containing vapor stream and a residue. The fractional distillation unit comprises a plenum for receiving the cannabinoid-containing vapor stream and separates a first cannabinoid from at least a second cannabinoid. The condensing unit is configured to receive a portion of the cannabinoid-containing vapor stream comprising the first cannabinoid from the plenum and to form a condensed first cannabinoid output stream and a recirculate stream. There are also disclosed methods for isolating one or more cannabinoids employing a recirculate stream.

A distiller including an evaporator having at least one evaporation surface for evaporating liquid into vapor. At least one movable liquid applicator assembly has a wiper applicator which can move over the at least one evaporation surface, for wiping and applying a thin even film of the liquid on the at least one evaporation surface for evaporation.

A vertically-integrated Cannabis-related product production method is described, the method comprises, producing a distilled cannabinoid and/or a crystallized cannabinoid from Cannabis plants, comprising: in a farming system, growing the Cannabis plants, the Cannabis plants comprise a cannabinoid; in an extraction system, extracting the cannabinoid from the Cannabis plants; in a purification system, purifying the cannabinoid to produce a purified cannabinoid; and in a distillation and/or a crystallization system, distilling and/or crystallizing the purified cannabinoid to produce the distilled cannabinoid and/or the crystallized cannabinoid. Various ways to purify, distill, and process the cannabinoids are described. An insect pest management system may be integrated with the farming system to grow the Cannabis plants in the presence of predatory mites which feed on insects and/or spider mites.

A device for the contact of a gas phase with a liquid medium, and a method for operating the device. The liquid medium here is directed into the device and some of it is raised by means of a conveying device. The liquid medium raised is distributed over a rotating brush by way of a distributing means. At least one gas inlet and a fan here generate a gas stream from a lower portion of the device to an upper portion of the device. The liquid medium distributed over the upper surface of the brush is directed back by way of the brush, counter to the gas stream, into the lower region.
