Wave extraction machine technology is a new technology for extracting effective ingredients from food and traditional Chinese medicine. Through more than ten years of efforts and development, microwave extraction technology has been applied to spices, condiments, biological products, natural pigments, tea, Chinese herbal medicine, cosmetics and soil analysis.

1. Principle of microwave extraction machine

Microwave extraction is a process in which high-frequency electromagnetic waves penetrate the extraction medium and reach the inside of the extracted material. Microwave energy is quickly converted into heat energy to rapidly increase the temperature inside the cell. When the pressure inside the cell exceeds the bearing capacity of the cell wall, the cell ruptures, and the effective ingredients in the cell flow out freely, dissolve in the extraction medium at a lower temperature, and then further filter and separate to obtain the extracted material. Under the action of microwave radiation, the components of the extracted material are accelerated to diffuse to the extraction solvent interface, thereby increasing the extraction rate several times, while also reducing the extraction temperature, and maximizing the quality of the extraction.

2. Advantages of microwave extraction machine

a. High quality, can effectively protect the functional components in food, medicine and other chemical materials;

b. High purity and high extraction rate;

c. High selectivity for extracts;

d. Fast speed and time saving, can save more than 50%-90% of time;

e. Less solvent usage (can be less than 50%-90% of conventional methods);

f. Safe, energy-saving, pollution-free, simple production equipment, saving investment.

3. Comparison of microwave extraction with other extraction methods

Microwave extraction has high efficiency, high purity, low energy consumption, low operating cost, and meets environmental protection requirements. It can be widely used in Chinese herbal medicine, spices, health food, food, cosmetics, tea beverages, seasonings, pectin, high viscosity chitosan and other industries. At present, microwave extraction has been used in many Chinese herbal medicine extraction production lines in my country, such as Pueraria root, tea, ginkgo, etc. Microwave extraction has been listed as one of the modernization and promotion technologies for food processing and Chinese medicine pharmaceutical manufacturing in my country in the 21st century. Researchers from a Chinese medicine research institution have used microwave extraction methods to process hundreds of Chinese medicines. Whether it is extraction speed, extraction efficiency or extraction quality, it is much better than conventional processes. Microwave extraction technology has obvious advantages over other existing extraction technologies.
