Short Path Distillation Machine

The operation process of the short path distillation machine is that the steam generated after the mixed liquid boils enters the fractionation column, where it is partially condensed, and the condensate contacts with the rising steam on the way down, and the two exchange heat, so that the high-boiling components in the steam are condensed, while the low-boiling components in the condensate still rise as steam, while the low-boiling components in the condensate are heated and gasified, and the high-boiling components still fall as liquid.

This process is repeated repeatedly, which is equivalent to ordinary distillation for many times in a row. As a result, the low-boiling components in the rising steam increase, and the high-boiling components in the falling condensate increase. In this way, after many times of heat exchange, the separation of high boiling point components and low boiling point components is realized.

In addition to short-path distillation, there are the following common separation technologies:

◆ Distillation: The method and process of separating components in liquid mixture by using their volatility.

◆ Sublimation method: the phenomenon that a solid substance is directly transformed into a gas state without being in a liquid state, which can be used as a method for separation by using solid-gas equilibrium.

◆ Crystallization separation method: The solubility of solid in solvent generally increases with the increase of temperature. If the solid is dissolved in a higher temperature solvent to reach saturation, after cooling, the solution will become supersaturated due to the decrease of solubility, and crystals will be precipitated.

◆ Salting-out method: A small amount of salt (such as ammonium sulfate, sodium sulfate, ammonium chloride, etc.) can promote the dissolution of protein. When the salt solution added to protein reaches a certain concentration, the solubility of protein is reduced and precipitated from the solution.

◆ Precipitation separation method: The sample components are precipitated by chemical reaction to form precipitation or adding precipitant to destroy the stability of colloidal solution, and then the precipitated components are obtained (or discarded) by filtration or centrifugation.

◆ Extraction separation method: Liposoluble molecules are extracted with organic solvent and then volatilized to remove the solvent.

◆ Chromatographic separation method: when the sample flows through the chromatographic column, the components are separated one by one because of the different residence time on the column for physical and chemical reasons.

◆ Electrophoretic separation method: This is established according to the phenomenon that the particles with points move towards the opposite electrode under the action of electric field.

◆ Centrifugal separation plate method: It is a method to separate substances under the action of centrifugal force by using the sedimentation coefficient difference of colloidal solute.

In short range distillers, the scraper separation device is a key component, especially in rotary scraper short range distillers. The main function of this device is to increase the mass transfer area by scraping the thin layer of liquid, while maintaining the uniformity and stability of the liquid film through rotation, thereby improving the separation effect.

Specifically, the scraper separation device consists of a series of scrapers installed on a rotating shaft. When the rotating axis begins to rotate, the scraper will continuously scrape the thin layer of liquid inside the still. This process not only increases the contact area between the liquid and the wall of the still, thereby improving mass transfer efficiency, but also maintains uniformity and stability of the liquid film through the movement of the scraper.

The scraper separation device in short path distillation machine is a common separation device, which can realize efficient and accurate separation process. A separation device in the form of a scraper usually consists of the following parts:

Advantages
◆ Efficient separation: Short-range distillation machines can achieve efficient separation of components in the mixture, especially for components with similar boiling points or similar physical properties, the separation effect is better.
◆ Low temperature operation: Due to the high vacuum, the short-range distillation machine can operate at a lower temperature, avoiding the damage of high temperature to heat-sensitive substances, maintaining the purity and quality of the separated substances.
◆ Energy saving and environmental protection: The short-range distillation machine can achieve low temperature distillation in the distillation process, reducing energy consumption, while reducing waste gas and wastewater discharge, in line with the requirements of sustainable development.
◆ Strong flexibility: The short-range distillation machine can adjust the heating temperature, system pressure and condensing surface distance according to different material characteristics and separation requirements to achieve the best separation effect.

Disadvantages
◆ High equipment cost: The structure of the short-range distillation machine is complex, the material sealing requirements are high, and the distance between the evaporation surface and the condensing surface should be moderate, resulting in greater difficulty in equipment processing and higher cost.
◆ Operation is relatively difficult: the operation of short-range distillation machines requires a certain amount of professional knowledge and experience, and operators need to understand the working principle and operation process of the equipment to ensure the normal operation of the equipment and the accuracy of the experimental results.
