Using biaxial stirring, the humidity thick spiral promote rapid drying of materials suitable for high viscosity and high humidity drying materials can be the beginning of the aquifer below 65% humidity drying materials to a final moisture content 5-12 %, drying time is short, typically 2-20 minutes. As high-speed stirring intense mixing blade materials humid, wet materials can be good contacts with hot air. Materials in the first half of the rapid evaporation of moisture, air temperature inside the aircraft sharp decline, so even if the use of hot air temperature, the material temperature is not high. Typical applications such as sludge drying plaster drying, sludge drying, Peng Run soil dry distiller's grain drying, Marc dry Luezha dry, dry bean dregs, sugar residue dry paste residue dry peat drying, and rare earth materials, such as high humidity dry, organic and inorganic compounds and chemical raw materials such as Muddy, granular powder, flake materials humidity drying. After drying material size of 2-5 mm, and materials in the process of drying temperature is not high, applicable to thermosensitive material.
