Thin film rectifying columnn is a device that couples a thin film evaporator with a  rectifying column. During the distillation process, the thin film rectifying columnn can address the issue of thermal decomposition of heat-sensitive materials caused by excessive bottom temperatures and prolonged residence time in the reboiler. The excellent features of the thin film rectifying columnn, such as vacuum, film scraping, and distillation, can be widely applied in industries such as biopharmaceuticals, food, plant extraction, and chemicals.
The thin film rectifying columnn effectively prevents materials from undergoing degradation reactions such as decomposition, polymerization, and oxidation due to heat, thus protecting the properties of the product materials. Compared to traditional thin film evaporators, the film distillation column adds the function of distillation, which enhances the product's purity and reduces the number of purification steps required.
