Air Flow Dryer
Air flow dryer, also known as pneumatic drier or sawdust dryer, is an important equipment in the production and processing of wood powder. The air flow dryer is a good choice for processing the finished material of low melting point, wood chips(sawdust), wood powder, wood pellet, flour, feed and so on. The fastest speed and best economic benefits can be obtained with the minimum investment, energy consumption, manpower and area by using the air flow dryer.

Features of air flow dryer:
1. Large drying intensity of the air flow dryer: because of the high air velocity, materials are dispersed well in the gas phase and the whole surface of the material is the effective area of drying, therefore, the dry area is greatly increased. At the same time, due to the effect of dispersing and stirring when drying the material, so that the surface of gasification is constantly updated, thus the heat transfer process of drying is larger.
2. Short drying time of the air flow dryer: the contact time of material and air is quite short. The drying time is usually 0.5 to 5 seconds. Overheating or decomposition will not caused for heat-sensitive or low melting point materials and affect its quality.
3. High thermal efficiency of the air flow dryer: materials and gas are co-current in the air drying. Both the material temperature and air temperature can reach a reasonable state from the beginning to the end with short drying time, therefore, higher drying temperature can be achieved.
4. The air flow dryer is featured with wide application, high productivity, large precipitation, simple structure, less occupied area, low investment and maintenance cost.
5. The hot air source of the air flow dryer: fuel stove, gas stove, coal stove, steam heat exchanger.
Operational processes of the air flow dryer:
1, After installation, open the air blower and check the direction of the air blower rotates and the feeding port.
2, Check the flange interface to see whether there is leakage.
3, The feed opening of the separator is tied up with the bag which is open at both ends.
4, Feed materials to be dried in the feeding port. Large particles should be removed before drying, which is conducive to improve the drying rate.
5, Add fuel into the furnace and ignite the fuel. Open the air blower and start feeding the material for drying when the outlet temperature is up to 150℃.
6, Remove bulk materials in the discharging port timely for ease of feeding.
The air flow dryer is a pre-treatment facilities always with a pellet mill or a briquette machine.
