Integrated rotary evaporator apparatuses are provided. Such rotary evaporators include a vertically oriented evaporator for evaporating a sample to form a sample evaporate, a mixing apparatus for mixing the sample in the evaporator, a condenser for condensing the evaporated sample into a condensate, a collection vessel for collecting the condensate, a vacuum pump to create a vacuum in the evaporator, and a refrigeration system integrated into the condenser, where all components are integrated into a single apparatus. Standalone large-scale chillers for cooling a liquid, vapor or other medium are also provided. Such chillers include a heat exchanger or evaporator, a condenser, a compressor, and a temperature controller, all integrated into a single standalone chiller usable with any vessel or reservoir containing liquids, vapors or other medium from which heat is to be removed. Methods of using such devices to distill, evaporate and/or cool a sample or medium are provided.

A rotary evaporator for evaporating a substance contained in an initial substance comprises an evaporation flask (2) for receiving the initial substance, a device (3) for heating the substance, a condenser (4) for condensing the vaporized substance, a collection container (6) for receiving the re-liquefied substance and at least one device (5) for generating a low pressure and/or an excess pressure. In order to remove the re-liquefied substance an excess pressure can be generated at least within the collection container (6) and/or in order to remove residues of the initial substance an excess pressure can be generated at least within the evaporation flask (2).

Methods of making a powdered milk product are 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 process of converting cannabidiol (CBD) to Δ.sup.8-tetrahydrocannabinol (Δ.sup.8-THC) or Δ.sup.9-tetrahydrocannabinol (Δ.sup.9-THC) can enable mass production of Δ.sup.8-THC and/or Δ.sup.9-THC, achieve greater yields and higher purity in comparison to previously reported processes while eliminating the use of organic solvent. The resultant hemp-derived Δ.sup.8-THC can be mixed with and absorbed by natural extracts, including tea extract, starch, sugar, lecithin, and other emulsifiers. Δ.sup.8-THC used in edible, topical and vaping products such as powdered Δ.sup.8-THC food ingredients, tablets or pills, suppositories, and vape formulations are disclosed. Further described are beverages and baked goods utilizing or incorporating the tablets or powdered Δ.sup.8-THC to create edible products containing an emulsified, tasteless, and odorless dose of Δ.sup.8-THC. The disclosure also describes a rectal suppository designed to provide improved comfort of use. A Δ.sup.8-THC liquid composition can be use in an electronic cigarette smoking device for pulmonary administration of Δ.sup.8-THC, which results in more effective absorption.

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 healed reactor, grinding the resulting powder, and disc hanging 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.

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 process for producing THC-O-acetate using a succession of distillation, salting-out assisted liquid-liquid extractions (SALLEs), and solvent recovery techniques. Tetrahydrocannabinol (THC) in cannabis oil reacts with acetic anhydride under reflux to produce THC-O-acetate and acetic acid. The resulting crude product is distilled and subjected to a SALLE with hexane followed by a SALLE with petroleum ether, before being distilled again in order to obtain a refined, THC-O-acetate product.
