This system consists of scraped thin-film evaporator, preheater, condenser, cooler, methanol recovery tank, finished product tank and piping. The equipment is applied to distribute the blended liquid to form thin-film evenly byusing high-speed centrifugal scraper for realization of evaporation or distillation. The light parts inside the mixtures of liquid arecondensedthroughevaporation, which aims atthe function of separation. This device can be applied to the evaporation of methanol, ethanol or other relevant alcohol.Features of the equipment: (1)Distillationunder vacuum state gently. (2)Evaporation at lower temperature. (3)Short flow time and easy operation.
