The working principle of a microwave extractor is based on the electromagnetic wave characteristics of microwaves. High frequency electromagnetic waves penetrate the extraction medium and reach the interior of the material, causing the temperature inside the cells to rapidly rise, leading to cell rupture and releasing effective ingredients that dissolve in the extraction medium. Microwaves can penetrate the extraction medium and reach the interior of the material. Due to the absorption of microwave energy, the temperature inside the cell rapidly rises, increasing the solubility of the separated substance in the medium. Meanwhile, the electromagnetic field generated by microwaves accelerates the diffusion of extracted components towards the extraction solvent interface, thereby increasing the extraction rate.
The application of microwave extraction machine is very extensive, mainly including the following aspects:
Environmental analysis: used for the extraction and separation of pesticide residues, organic pollutants, metals and their compounds.
Chemical analysis: used for the extraction and separation of active ingredients in traditional Chinese medicine and plants.
Food analysis: used for extracting effective ingredients from food.
Natural product purification: used for extracting natural pigments, spices, seasonings, etc.
Mineral processing: used for soil analysis, etc.
Biochemical analysis: used for processing biological samples such as human blood (or serum).
• Clinical application: Used for the extraction and analysis of drug components.
The main features of microwave extraction machine are:
1. Fast reaction separation speed;
2. Energy saving and efficient, with short reaction and separation time;
3. Uniform material reaction and good product quality;
4. Easy to control, simple process, and other characteristics.
