Three-tube Dryer

The new drying machine ,being made up of the concentric drum of three different diameters according to the thermal technology principle, guarantees supplying enough residence time and sufficient scattering degree in the drying barrels, making the hot air current in supplies and fully heat exchange, fully utilize remaining energy of barrel, reduce heat losses. it reaches 40%-55% to improve thermal efficiency, save more than 50% of energy consumption, the actuator adopts and rubs the transmission, the sealed position is adopted and kept in touch and sealed a little, has reduced the working noise and pollution, reduce floor space, reduce investment of equipment, is perfect product to substitute single tube dry apparatus and pairs of tube dry substitute products . The fuel can adopt the coal, oil, gas, can dry a piece of material, a grain of material,and powder of material , the floor space of the apparatus saves about 50% more than the drying-machine of the single tube, save about 25% more than the drying-machine of a pair of tube, the investment of building construction reduces correspondingly. This product has independent intellectual property right, the patent number is: ZL200520075244.2
