The principle of extraction equipment
The principle of extraction equipment is to use the difference in solubility or distribution coefficient of substances in two immiscible (or slightly soluble) solvents to transfer solute substances from one solvent to another.
Below, the editor will briefly introduce several common extraction equipment and their working principles, as follows:
1. Microwave extraction equipment: This equipment uses microwave heating to decompose, crack, and evaporate the active ingredients in the raw materials, causing resonance effects on water molecules and activating them. Then, the water molecules are separated from the water by a centrifugal device, and after removing impurities through a filtration device, a high concentration extraction solution is obtained.
2. Ultrasonic extraction equipment: It is a method of extracting substances by utilizing the hole effect and proximity effect generated by the propagation of ultrasonic waves in liquids.
3. Counter current chromatography equipment: It uses a special structured stationary phase to separate the components in a mixture
4. Solid phase microextraction equipment: It utilizes the interaction force between the surface functional groups of solid particles and the solvent to selectively extract solutes.
Different extraction equipment is suitable for different materials and environments. Choosing the appropriate extraction equipment can improve extraction efficiency, reduce costs, and minimize environmental pollution.
