The working principle of vacuum rake dryer
acuum rake dryer is mainly composed of stirring shaft, cylinder, transmission system and sealing device and other parts. Dry calories is mainly provided by the stirring shaft and the cylinder jacket. When the heating medium access equipment, heat through the jacket and the stirring shaft to indirect heating of the material, moisture in wet material heated evaporation, evaporation of moisture is away just in time by vacuum system. With the continuous rotation of stirring shaft, material contact with the heating surface constantly updated, make the material evenly heat, so as to achieve good drying effect.
New type vacuum rake dryer mainly improved the dryer internal baffle type jacket, special flow type hot shaft, sealing structure these three aspects.
