Airflow dryer

Product introduction

product description
Airflow dryer range: suitable for drying powder and fine granular materials such as starch, cassava flour, gluten, flour additives, fish meal, lees, corn protein, grass, grass powder, titanium dioxide, activated carbon, sodium fluorosilicate, Fluorite, Silica powder, Synthetic resin, Calcium phosphate, Aureomycin, Sodium meta silicate, Glucose, Sodium sulfate, Sulfide ore, Phosphate powder, Molten phosphate, Iron oxide, Calcium carbonate, ilmenite, Iron oxide , Potato chips, tea meal, drugs, pharmaceuticals, coal, wood saw powder etc.
Airflow dryer is a hot air pulse dryer, also known as hot air pipe dryer, the advantages of this dryer is direct heating, drying fast, fold able installation, save space
Airflow dryer characteristics
1, Dry raw materials: rice husk, sawdust and crushed after the bubble flowers, branches, chips and other granular materials (diameter less than 3mm, length less than 5mm).
2, The production efficiency: hot air at 180 ℃, the relative humidity of 35% of the sawdust or rice husk drying to the relative temperature of 10%. Hot air temperature of not less than 180 ℃, up to 300 ℃.
3, the fuel can be used: wood , coal, steam or electric heating.

Performance characteristics
the performance characteristics of airflow dryer
1, dry strength: air dryer due to high air flow, the material dispersed in the gas phase is good, you can all the surface of the material as a dry effective area, so the limited area of dry greatly increased. At the same time, due to the drying and agitation of the role of dry, so that the Gasification surface constantly updated, so the dry heat transfer process strength.
2, short drying time: material and air contact time is very short, the drying time is generally 0.5 to 5 seconds, for the heat-sensitive or low melting point materials will not cause overheating or decomposition of its quality.
3, high thermal efficiency: air drying using material and gas co-operation, from beginning to end the material temperature and air temperature can reach a reasonable state, drying time is short, which can use a higher drying temperature.
4, a wide range of applications, high yield, large precipitation; simple structure, small site area, low investment and maintenance costs.
· Hot air source: fuel furnace, gas stove, coal hot stove, steam heat exchanger.
the use of methods
1, air dryer installed after the completion of the opening of the fan, check the direction of fan rotation and feeding port is suction normal.
2, check the flange interface to see if the leak. The following are the same as the "
3, in the air dryer dryer separator on both sides of the junction with the opening of the bag. The following are the same as the "
4, in the air dryer feeding port to be added to the dry material, in the dry before the need to remove large particles, which will help improve the drying rate. The following are the same as the "
5, in the air dryer furnace to join the fuel ignition, open the fan, when the wind outlet temperature up to 150 ℃, began cutting, drying. The following are the same as the "
6, timely removal of large pieces of slag discharge material, in order to facilitate feeding.
