Description

Technical Field

It has been widely used in the extraction of vitamins and effective ingredients of Chinese herbal medicines in the pharmaceutical industry, petrochemical industry, food industry, cosmetics industry, agriculture and other industries. The degreasing agent in the mixed liquid can be distilled by distillation equipment to evaporate the degreasing agent to obtain a purer degreasing agent solution.

[0003] For example, Chinese patent CN203329393U discloses a distillation device, which mainly includes a distillation kettle, a condenser and a product receiver. A heating coil is arranged inside the distillation kettle, and an oil inlet and an oil outlet are arranged at both ends of the heating coil, and the oil inlet and the oil outlet are both protruding from the distillation kettle. The distillation kettle is connected to the condenser through a pipeline, and the condenser is connected to the receiver through a pipeline. The "O"-shaped heating coil of the utility model can increase the heating area and ensure the distillation speed; as the liquid level of the material in the kettle decreases, the upper coil is gradually closed to reduce the temperature of the coil, so as to prevent the refluxed material from carbonizing when contacting the coil with a higher temperature, thereby reducing the bottom distillation ratio and greatly improving the product yield.
