Microwave extraction (extraction) mechanism is the microwave radiation high -frequency electromagnetic wave penetrating extraction medium, reaching the internal vascular bundle and gland cell system of the material. Due to the absorption of microwave energy, the temperature inside the cell rises rapidly, making the internal pressure inside the cells exceed the capacity of the cell wall expansion, and the cells are ruptured. The active ingredients in the cells flow out freely, and the medium is captured and dissolved under lower temperature conditions. By further filtering and separation, the extraction material is obtained. Microwave can be an energy form. It can produce many substances composed of polar molecules during the transmission process. Microwave electromagnetic fields make the molecularization of the substance instantaneous polarization. When the microwave with a frequency of 2450MHz can be extracted, the molecules of soluble or solvents are performed at a rate of 2.45 billion times per second to generate polar transformation movements, which will produce mutual friction and collision between molecules to promote molecular activity parts (pole extremes Sexual part) better contact and response, and quickly generate a large amount of thermal energy to promote the rupture of the cells, overflow the cell fluid and spread to the solvent. The effective ingredients of Chinese herbal medicines are used to extract the effective ingredients, infiltration method, return extraction method, and continuous return extraction method. In principle, the microwave can be added to assist the extraction, making it an effective Chinese herbal medicine effective extraction equipment. 1. Traditional thermal extract is performed from the inside in thermal conduction, thermal radiation, etc., and microwave assisting extraction is heating at the same time inside and outside. There is no high temperature heat source, eliminating the thermal gradient, so as to greatly improve the quality of the substitute, effectively protect the functional ingredients in food, medicines and other chemical materials; 2. Because the microwave can be heated through, the extraction time is greatly saved. According to a large amount of on -site data statistics, the conventional multi -function extraction can to complete the 8 -hour work. It only takes tens of minutes to complete the device with the same size of the microwave dynamic extraction. 3. Microwaves can have extraordinary extraction capabilities. The same raw materials need to be lifted in two or three times in conventional methods, and can be cleaned at one time under the microwave field. Great simplify the process. 5. Microwave extraction does not have heat inertia, easy to control, all parameters can be data, and the pharmaceutical modernization is in line. 6. Microwave extract is high, water can be lifted, alcohol, and fat. Wide applicable. 7. The extraction temperature is low, it is not easy to paste, it is easy to separate, and it is convenient for post -treatment. Save energy .8, the amount of solvents is small (less can be 50 % to 90 % less than conventional methods); 9. Microwave equipment is electrical equipment, without the need to be equipped with boilers, no pollution, safety, and green engineering; 10. The production line composition is simple and simple , Save investment; the microwave extraction equipment that has been developed is fully adapted to food and pharmaceutical projects of various large, medium and small enterprises in my country. Although the application research of microwave radiation technology in the food industry, pharmaceutical industry and chemistry industry has only started in just a few years, the existing research results and application results have been sufficient to show their superiority: the spices have been completed in the laboratory, and the spices have been completed in the laboratory, and the spices have been completed in the laboratory, and the spices have been completed in the laboratory, and the spices have been completed in the laboratory, and the spices have been completed in the laboratory. Study on the microwave extraction process of condiments, natural pigments, Chinese herbal medicines, cosmetics, health foods, beverage preparations and other products. At present, microwave extracts have been used in the infringing production lines of many Chinese herbal medicines, such as Pueraria, tea, ginkgo, and licorice. Micro -wave auxiliary extraction has been listed as one of the modernization of food processing and traditional Chinese medicine and pharmaceuticals in my country in the 21st century. Research institutions handle hundreds of natural plants with microwave extraction methods. Whether it is extraction speed, extraction efficiency, or extraction quality, it is much better than conventional craftsmanship. Performance description: Although the application research of microwave radiation technology in the food industry, pharmaceutical industry and chemistry industry has only started in just a few years, the existing research results and application results are sufficient to show its superiority: Function and characteristics: Microwaves Vacuum extraction equipment: According to the principle of different boiling points of the liquid boiling point at different air pressure, the microwave extraction vacuum and vacuum technology can be combined. The minimum can be performed at the temperature of 20-30 ° C room temperature. The equipment specifications are relatively complete. Essence Small equipment for colleges, scientific research institutes and various laboratories for trials, and large equipment is used for production units. The microwave power of the new series microwave auxiliary extraction equipment is from 1kW to 120kW, the volume is from 5 liters to 5 cubic meters, and the extraction temperature can be set at 30 to 100 ° C. The extraction solvent can be water, alcohol, and fat. You can also use weak polar solvents according to different materials and processes. Can be equipped with backflow and condensate device as needed. The application of many food and pharmaceutical manufacturers is good.
