Description

Clamping flow control type supercritical extraction pharmaceutical equipment

Technical Field

The invention relates to the technical field of pharmacy, in particular to a clamp-belt flow control type supercritical extraction pharmaceutical device.

Background

Supercritical fluid is a supercritical fluid, which is a non-gaseous and non-liquid state between gas and liquid, and can exist only when the temperature and pressure of the substance exceed critical points, the density of the supercritical fluid is higher and similar to that of liquid, and the viscosity of the supercritical fluid is closer to that of gas, so the supercritical fluid is an ideal extracting agent.

The solvent strength of the supercritical fluid depends on the temperature and pressure of extraction. By utilizing the characteristics, different components in a sample can be extracted sequentially according to the solubility in the fluid by only changing the pressure and the temperature of the extractant fluid, substances with weak polarity are extracted first under low pressure, and substances with larger polarity and large molecular weight and basic properties are extracted along with the increase of the pressure, so that the supercritical extraction is carried out under the program pressure to obtain different extracted components, and the separation effect can be realized. The temperature change is reflected in two factors which affect the density of the extractant and the vapor pressure of the solute, in a low temperature region (still above a critical temperature), the temperature is increased to reduce the fluid density, but the vapor pressure of the solute is not increased much, so that the temperature rise during the dissolving capacity of the extractant can make the solute be separated out from the fluid extractant, when the temperature is further increased to a high temperature region, although the density of the extractant is further reduced, the vapor pressure of the solute is increased, the volatility is increased, and the extraction rate is not reduced but increased.

Under supercritical conditions, CO2 has selective solubility. SFE-CO2 shows excellent solubility for low molecular, low polar, lipophilic, low boiling point components such as volatile oils, hydrocarbons, esters, lactones, ethers, epoxy compounds, etc. like the aroma components of natural plants and fruits. As more polar groups are added to compounds having polar groups (-OH, -COOH, etc.), extraction becomes more difficult, and thus, aromatic substances such as polyhydric alcohols, polybasic acids, and polyhydroxyl groups are less soluble in supercritical carbon dioxide. For a high molecular weight compound, the higher the molecular weight, the more difficult it is to extract, and a high molecular weight compound having a molecular weight of more than 500 is also almost insoluble. For the extraction of effective components of Chinese herbal medicines with large molecular weight and more polar groups, a third component is added into a binary system consisting of the effective components and supercritical carbon dioxide to change the solubility of the original effective components, and in the research of supercritical fluid extraction, the third component with the changed solubility of solute is generally called an entrainer (also called a subcritical component in many documents). Generally, solvents with good solubility properties, such as methanol, ethanol, acetone, ethyl acetate, are also often good entrainers.

The extraction rate of the existing supercritical extraction device generally depends on the extraction effect of an extraction kettle and the separation effect of a separator, because of the characteristics of supercritical fluid, the extraction kettle can easily complete high separation rate under the operation of changing temperature and pressure, even the separation effect is improved by means of multi-stage separation and rectification, but most of the extraction kettles still adopt a simple hanging basket form to hold materials for static extraction at present, the materials are difficult to fully contact with the supercritical fluid due to limited stacking and space, so that the one-way extraction rate is low, the extraction rate of the materials is often improved by adopting a mode of repeated extraction or continuous countercurrent extraction, an entrainer is simply mixed with the materials or carbon dioxide, the effect is poor, the extraction efficiency is greatly reduced, and the extraction cost is also improved.
