China Widely Used Hot Airflow Saw Dust Dryer

1.The description of hot airflow saw dust dryer

The hot airflow saw dust dryer is a hot air pulse dryer, also known as a hot air duct dryer. hot airflow saw dust dryer is widely used in food, feed, chemical, pharmaceutical, mining and other industries.The advantage of this dryer is direct heating, fast drying, foldable installation and space saving. The air dryer is used to mix the moist material with the high temperature airflow, and finally separate the water from the raw material through the separator.

2.working principle of hot airflow saw dust dryer

The furnace (boiler) produces hot air and then the material is dried by a fan.Charcoal briquette wood dryer is equipped with oil boiler, water inlet, steel pipe, exhaust fan (fan), cyclone separator. Wet feed to the hopper. The hot air generated by the fuel boiler is mixed with the wet matter and then quickly sucked into the pipeline through an exhaust blower (fan). The hot air then flows through the curved tube and the damper (drying chamber) of the dryer, so that the wet material is dried and the dried material is discharged by the exhaust blower (fan).

3.the feature of hot airflow saw dust dryer

Air dryer has high drying strength: hot airflow saw dust dryer has high airflow speed, and the material is well dispersed in the gas phase. The entire surface of the material can be used as the effective area for drying. Therefore, the limited area of drying is greatly increased. At the same time, due to dispersion during drying and Stirring action, so that the gasification surface is constantly updated, therefore, the drying heat transfer process is strong.

The air drying machine has a short drying time: the contact time between the material and the air is extremely short, and the drying time is generally 0.5 to 5 seconds. The heat sensitive or low melting material does not cause overheating or decomposition and affects its quality.

The hot airflow saw dust dryer has high thermal efficiency: the airflow is dried by the cocurrent operation of the material and the gas, and the material temperature and the air temperature can reach a reasonable state from the beginning to the end, and the drying time is short, so that a higher drying temperature can be used.
hot airflow saw dust dryer has wide application range, high output and large precipitation range; simple structure, small station area, low investment and maintenance cost.

hot airflow saw dust dryer has a wide range of hot air: oil burner, gas furnace, coal-fired hot blast stove, steam heat exchanger.
