The disclosure provides methods and reagents for removing pesticides or pesticide residues from plant matter such as cannabis plant matter. The method uses adsorption on bentonite (bentonite scrubbing).

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. In 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.

Methods and systems for removing water from a manganese-based etchant bath are disclosed. Water is removed from the manganese-based etchant bath by transferring a portion of the manganese-based etchant bath to a vacuum evaporator for processing and transferring the concentrated portion of the manganese-based etchant bath back to the manganese-based etchant bath.

Method and device for the preparation of monophasic powders of actinide salts which are precursors in the production of fuel pellets. In one aspect, a compact and simple device is provided to obtain dry monophasic powders of actinide salts in one stage, while increasing the productivity, chemical and nuclear safety of the process. In a second aspect, the method comprises feeding of nitric actinides-containing solution and formic acid to a cylindrical heated reactor, grinding the resulting powder, and discharging the powder. The nitric actinides-containing solution and formic acid are continuously metered to the upper zone of the reactor so that the reactive chemicals are mixed in a thin film on the heat-exchange surface, where the reaction mixture is continuously stirred by rotor blades. Also occurring are the processes of denitration, formation of the relevant compounds, their drying and grinding and collecting dry salts of actinides in a hopper by gravity.

Embodiments presented provide for a multirotational counter rotating reactor. The reactor is configured to accept a fluid stream and separate the fluid stream into high quality liquid and gaseous phases through spinning of the sets of discs as well as through performing a heat transfer to the fluid stream.

A distillation apparatus includes an evaporator-condenser heat exchanger in combination with a compressor. The heat exchanger is mounted to float in an at least partially immersed position in a sump of liquid. The liquid may be a sap, or may be soiled water, and may have suspended solid. Heating of the liquid yield steam, the steam is compressed, and the heated, compressed steam is fed back into the heat exchanger to provide further heat to the liquid. The process yields a concentrated in the liquid bath and distilled water, each of which may be a desired product. The system may include a pre-heater that exchanges residual heat from the hot distillate with the cooler input liquid. The apparatus and process may have multiple stages.

A rotary evaporator includes a sample flask having a reservoir for receiving a sample and a neck in communication with the reservoir. The neck extends along an axis and a purge tube extends within the neck of the sample flask along the axis. The purge tube includes a distal end and at least one opening formed in the purge tube at the distal end, the distal end being closed. Purge gas is supplied to the purge tube and injected into the sample flask via the at least one opening. The purge tube is movable along the axis via an actuator, between a retracted position, where the distal end of the purge tube is situated in the neck of the sample flask, and an extended position, where the distal end of the purge tube is situated in the reservoir of the sample flask.

Methods of making a powdered milk product as described. The methods may include providing an aqueous milk-sourced mixture, and evaporating water from the aqueous milk-sourced mixture to produce an evaporated milk-sourced mixture having a total solids concentration of 35 wt. % or more. The evaporated milk-sourced mixture may be dried to form the powdered milk product, which may have less than 6 wt. % water. Systems for making the milk powdered product are also described. The systems may include an evaporator to evaporate water from a supply of a milk-sourced mixture to form an evaporated milk-sourced mixture. They may also include a dryer to dry the evaporated milk-sourced mixture and atomize it into the powdered milk product.

A distillation unit multiple rejection areas at each of a top of a flask and a top of a lower distillation tube in embodiments. A middle distillation tube is narrower than the lower tube and extends into the lower distillation tube as well as a fraction collector. A distillation key with rings extends downwards through the fraction collector, middle distillation tube, and lower distillation tube, a portion of the distillation key and the lower distillation tube extending into a flask where product to be purified is placed. In this manner, the flask itself acts as a heat jacket in addition to having a heat jacket around all the afore-described parts.
