A kind of equipment for drying with microwave heating principle
Microwave dryer is a kind of equipment that uses microwave heating principle to dry.
- Chinese name
- Microwave dryer
- Principle
- microwave heating
characteristic
Generally, several microwave generators are used in series. The DC power supply generates microwave power (frequency 2450MH}, wavelength 12.5m) through the microwave tube, which is transported to the material surface by the direct wave ` i 'tube. A stirrer is installed between them to interfere with the microwave and achieve uniformity. The wet material is conveyed by the conveyor belt, and the moisture is continuously evaporated under the effect of microwave heating, and discharged by the exhaust fan. The advantages are: t1) uniform heating, good permeability; Eat) short heating time, fast drying speed;} 3) } i Small land area, high production intensity; (43) High thermal energy utilization rate; [5) Good product quality; (The process is simple, and it is easy to realize white motion control. The disadvantages are: (1) High protection requirements;}?) Strong selectivity, which cannot be used for materials containing metal ions; (3) High manufacturing cost. The complete microwave dryer must be equipped with monitors, regulators, isolators, indicators and other accessories, as well as water load and residual power indicators to absorb residual power. Broad should be great at Chemical Reagents , medicine, film, paper, food, grain, etc [1]
