Learn More About Microwave Drying Machine
Jun 12, 2025
The core principle of microwave drying machine:
The microwave drying machine generates high-frequency electromagnetic waves (usually 2.45GHz) through magnetron, which makes the water molecules inside the material generate high-frequency vibration friction and heat, achieving rapid drying from the inside to the outside. Compared with traditional hot air drying, its energy utilization rate is increased by more than 40%, and there is no external heat conduction loss.
Application areas and typical cases
Food processing: innovation in locking freshness and quality
Fruit and vegetable dehydration: Microwave drying of apple slices, dried mangoes, etc. can retain more than 90% of vitamins and avoid browning caused by traditional hot air (picture: fresh apples vs. microwave dried apple slices).
Meat thawing and drying: The thawing time of quick-frozen seafood is shortened by 70%, and it is also used in the production of meat jerky, and the moisture evaporates evenly without shrinking.
Tea drying: Longjing, Pu'er and other teas retain the aroma of tea polyphenols in 60℃ low-temperature microwave drying, and the energy consumption is only 1/3 of that of electric ovens.
Wood drying: industrial-grade efficient production
Furniture wood processing: Oak, pine and other thick wood boards are deeply dried within 24 hours (moisture content reduced to 8%) to avoid the cracking problem of traditional kiln drying (picture: microscopic comparison of wood cross section).
Bamboo product processing: Bamboo floors and bamboo crafts are quickly dehumidified and mildew-proof, with an efficiency 5 times higher than steam drying.
Medicine and Chemical Industry: Precise Moisture Control and Sterilization
Drying of Chinese Herbal Medicines: Lycium barbarum, Astragalus membranaceus, etc. are dried at a constant temperature of 50°C, and the loss rate of effective ingredients is less than 5%
Processing of Chemical Materials: Lithium battery separators and polymer films are dried at low temperature in an inert environment to avoid thermal decomposition.
Agriculture and biomass: environmental protection and resource utilization
Straw carbonization: agricultural waste is rapidly carbonized by microwaves to generate biochar for soil improvement.
Fruit drying: tropical fruits such as durian and lychee are made into snack foods with a dehydration rate of >95% and no additives.
