摘要： A multi-stage evaporation system enhanced by a gravity-reduced field consists of evaporation structures of multiple stages. There are three different operation modes, namely, a serial-connected air and parallel-connected solution mode, a serial-connected air and serial-connected solution mode, and a parallel-connected air and serial-connected solution mode. In the evaporation chambers, the solution directly contacts the air to transfer the heat and mass. The solution is sprayed on the rotating filling material, and is uniformly distributed under the action of the gravity-reduced field, which enhances the heat and mass transfer. The solution is gasified by absorbing the heat energy thereof. Meanwhile, the air can carry more water vapor after being heated by the solution and thus having an increased temperature, and take away the gasified solution, thereby achieving the purpose of evaporation.

摘要： 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.

摘要： 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.
