The problems such as, and operation and maintenance cost is high.And the factory of small scale is also unpractical typically under the pressure of a set of GGH in economic pressures.
In known drying process, either heated using electrical heating, steam, or fuel heating, conduction of heat, hot spoke
Penetrate, the transmission of heat is carrying out from outward appearance to inner essence, need to could remove moisture through the long period, reduce drying efficiency.Due to micro-
Ripple has preference heat characteristic to water, and its efficient drying object mainly removes moisture, greatly reduces energy consumption, and
Effectively prevent the discharge of greenhouse gases and pollutant.
