Product Introduction
Hot air dryer adopts double-shaft mixing and screw propulsion to dry sticky and high-moisture materials. Hot air dryer can dry materials with 65% moisture to below 5% to 12% at one time. Drying period is very short, 2 to 20 minutes. Blades in hot air dryer can stir wet materials intensively, wet materials can contact fully with hot air. Moisture content of wet materials can be greatly evaporated faster in the former half part. Temperature of hot air in dryer drops sharply. Therefore, although hot air dryer applies hot air with high temperature, the temperature of raw materials will not increase greatly. Hot air dryer is typically applied to drying sludge, gypsum, ore slurry, bentonite, brewer grain, pomace, medicine dreg, medicine, peat and etc. after being disposed by hot air dryer, the final size of raw materials are 2 to 5mm. during the drying process, temperature of materials is not very high, therefore this kind of drying process is suitable for thermal-sensitive materials.
Product Superiority
Owing to high velocity of air flow, materials can be evenly distributed in hot air mixing dryer. Almost each part of materials can be regarded as effective drying area. Meanwhile, owing to dispersion and agitation function, gasification surface can be updated continuously. Therefore, heat transfer process is very strong.
Short drying time
There will be a concurrent flow between materials and airflow. Temperature of both materials and air can reach to a reasonable state. Drying time is very short, so pretty high drying temperature can be adopted.
Wide application
Wide application, high output capacity, great moisture reduction, simple structure, small area occupation, less investment and maintenance cost.
Multiple heat source option, less energy consumption
Oil furnace, gas furnace, coal furnace, steam heat exchanger; less energy consumption and less running cost.
Reasonable design
Compact design; less area occupation, less noise, less vibration, PLC control system, safe and reliable; matched with efficient furnace and tail gas purification system, the whole system is characterized by high efficiency, low energy consumption and no pollution.
