Abstract Microwave technology is widely used in the production and research of traditional Chinese medicine. It has involved several major natural compounds such as volatile oils, glycosides, polysaccharides and flavonoids in the extraction of biologically active ingredients. In addition, microwave has been introduced into traditional Chinese medicine microwave drying equipment, sterilization, processing, decoction and other aspects, with fast speed, uniform effect, energy saving, less pollution, good boiling effect, easy to achieve automatic control and good product quality, etc. Many advantages.
Key words: microwave Chinese medicine; application
Microwave refers to the frequency range of 3. 0 × 102 ～ 3. 0 × 105 MHz, extremely short wavelength (0. 001 ~ 1. 000 m) electromagnetic waves. Microwave has good penetrating power and penetration selectivity, can penetrate plastic, but has reflectiveness to metal, can not penetrate, can use metal as shielding device; microwave only selectively heats polar molecules, molecular pole The stronger the sex, the higher the selectivity; the microwave interacts with the substance in the high-frequency electric field with extremely short oscillation period. The strong internal heat effect and the extremely high frequency can make the solvent and the solute molecule have no thermal resistance at the same time, no thermal inertia.
