This equipment combines the functions of counter-current and microwave, being the first product in China to apply microwave energy in continuous counter-current extraction equipment. It is mainly used for extracting natural plant components, and can also be used for extracting substance components in food, health supplements, and biological products, as well as for aromatic oil recovery. It has a wide range of applicability. It has the advantages of high efficiency, convenient operation, and high extraction efficiency, and meets GMP requirements.

The extraction solvent and medicinal material counter-current method is: the medicinal materials and the solvent move in opposite directions in the extraction container, using the method of combining concentration difference and natural water pressure to complete the extraction process. This equipment is an efficient continuous dynamic counter-current extractor. Its extraction principle is: using the strong heating ability of microwave to make the medicinal materials and the solvent maintain relative motion, allowing the concentration of the liquid to diffuse and update continuously, thereby ensuring the fast extraction speed of the liquid.

The microwave counter-current organically combines microwave and traditional counter-current extraction equipment, enabling long-term continuous safe operation, and is easy to maintain and repair. When extracting materials on this machine, the output is greatly increased, meeting the needs of industrial production; at the same time, the pipeline extraction equipment solves the problems of traditional counter-current extraction equipment such as inability to stir the materials, uneven extraction, poor sealing performance, internal mechanical component wear, and pollution. Using this microwave equipment, it has been proven that it can significantly improve the extraction efficiency of traditional Chinese medicine and natural products, shorten the extraction time, and is a new technology with industrial production extraction application value. 

Specific indicators: 

(1) The purity and quality of the extract are high and good, effectively protecting the functional components in food, drugs, natural products, and other chemical materials. 

(2) It saves time, can save 50%-80% of time, as microwave can penetrate heating, greatly saving extraction time, with high efficiency and large output. 

(3) The microwave has an extremely long extraction capacity. With the same raw materials, it usually takes two or more times to extract completely by conventional methods, but in the microwave field, it can extract completely in one go, greatly simplifying the process flow. 

(4) Microwave extraction has no thermal inertia, is easy to control, all parameters can be dataized and integrated with modern Chinese medicine, using a wide range of solvents, such as water extraction, pure extraction, lipid extraction, with less solvent usage (50%-80% less than conventional methods)

 (5) Microwave extraction is an electrical equipment, does not need to be equipped with a boiler, has no pollution, is safe, and belongs to a green engineering. 

(6) The production composition is simple, the equipment occupies less space, saves investment, and has low operating costs.
