The working principle is as follows: molecular distillation is a special liquid-liquid separation technology, which is different from traditional distillation and relies on the principle of difference in boiling point and difference in mean free path of molecular motion of different substances to realize separation. When the materials to be separated enter from the feeding hole, the hanging basket is in a rotating state, so the materials to be separated are thrown to the inner wall surface of the heating cylinder under the action of centrifugal force, and then under the action of the film scraping of the rotating film scraper and the action of gravity, the materials form a uniform liquid film along the wall surface of the heating cylinder and move downwards. After heating, light and heavy molecules in the material can escape from the surface of the liquid film and enter a gas phase. Because the free paths of light molecules and heavy molecules are different, the moving distances of the molecules of different substances after escaping from the surface of the liquid film are different. Because the distance between the condensing tube and the heating surface is less than the mean free path of the light component molecules and greater than the mean free path of the heavy component molecules, the light component molecules escaping from the surface of the liquid film can reach the condensing surface and are continuously condensed, while the heavy component molecules can not reach the condensing surface, so the heavy component molecules return to the liquid film again to form the residual liquid, and the separation of the light component and the heavy component of the liquid mixture can be realized. Finally, the light components (i.e., the monoester) collected by condensation are discharged from the distilled liquid outlet, and the heavy components (i.e., the diester) are discharged from the raffinate outlet.
Has the advantages that: the utility model discloses a wiped film type molecular still, the bottom of its hanging flower basket is equipped with the gyro wheel dismantled that contacts with the inner wall of heating barrel. When the hanging basket is rotated, the roller can roll on the inner wall of the heating barrel, so that the hanging basket is prevented from shaking, the condition that the film scraper, the bearing and the like are damaged due to shaking of the hanging basket is avoided, the service life of the molecular distiller is prolonged, safety accidents are reduced, the film forming effect is improved, and the product quality and the product yield are improved.
