Molecular-distillation purification method of celery seed oil and purification device thereof

Abstract

The invention discloses a molecular-distillation purification method of celery seed oil and a purification device thereof. The purification device consists of a hot oil machine, a cold water machine, a material tank, a thermostatic bath, a grade-I evaporator, a grade-II evaporator, a cold well, a water ring pump, a rotary vane pump, a diffusion pump and a controller, wherein the hot oil machine is communicated with the grade-II evaporator through a hot oil pipe; one end of the cold water machine is communicated with the grade-II evaporator through a first cooling water pipeline; the other end of the cold water machine is communicated with the cold well through a second cooling water pipeline; and the grade-I evaporator is communicated with the grade-II evaporator through a vacuum cavity pipeline and a second material conveying pipeline. The molecular-distillation purification method comprises the steps of: first, preparation work; second, the process of distillation separation; and third, shutdown. The method and the device have the beneficial effects of greatly enhancing the production efficiency, lowering the cost of purifying the celery seed oil, improving the working environment of workers, truly raising the automation control degree in purification of the celery seed oil, and being high in reliability and remarkable in practical effect.

Description

technical field [0001] The invention relates to a molecular distillation purification method of oil plants and a device thereof, in particular to a molecular distillation purification method of celery seed oil and a device thereof. Background technique [0002] At present, the distillation device is the core production equipment used in many fields such as medicine, food, petroleum, chemical industry, seawater desalination, etc. It can purify and separate many liquid substances by using different boiling point differences to heat raw materials and condensing evaporating products in stages. [0003] Molecular distillation is a liquid-liquid separation technology under high vacuum conditions. It has the characteristics of low operating temperature, short heating time, high degree of separation, and low energy consumption of the system. It can make liquid Separation is carried out at a temperature much lower than its boiling point, especially suitable for separating high boilin...
