Sawdust dryer profile
　Sawdust dryer refers to powder body shape wet sawdust, the screw conveyor will join the continuous drying tube. The heat flow in the high speed transmission and dispersion, the wet material is the water evaporation, get powder or granular dry product process. Mainly by the air heater, feeder, air drying tube, cyclones, fans, etc.
Sawdust dryer
Sawdust dryer characteristics
　1, drying intensity as the materials in the air high dispersion, particle total surface area is drying of effective area.
　2, air drying apparatus structure is simple, cover an area of an area small, easy to build and repair.
　3, large in capacity, high thermal efficiency. When drying not bound water, thermal efficiency can reach 60%.
Sawdust dryer applicable scope
　Pneumatic sawdust dryers are widely used in straw briquette fuel, charcoal machine, sawdust pellet fuel, sawdust briquette, farming and animal husbandry engineering, etc. Such as corn straw drying, soybean straw drying, cotton straw drying, wheat straw drying, sorghum stalk baking, drying, drying wood shavings, sawdust drying, ginkgo biloba drying, mulberry leaves, such as drying agricultural cellulose class material drying.
Sawdust dryer work flow
　Sawdust dryer equipment including equipment effective heat furnace, feed port, rotating drum, cartridge filters, material conveying pipe, cooling tube and discharging mouth, rotating cylinder is located in the active roller, active roller by motor and reduction drive drive rotary drum low-speed rotation, heating furnace and the rotating cylinder with feed between mouth, rotating drum equipped with a stir in the rotary drum, blade and cartridge filters. To place a board, board to open a hole, the filter tube end of the rotating cylinder is linked together, the other end and material conveying pipe connected, cartridge filters equipped with a stop, the bottom of the cartridge filters with discharge hole, cooling tube end through the blower and material conveying pipe connected, the other end of the discharge port connected.
　Because is to use the equipment design, so can make sawdust in rotary drum in uniform for drying, and in the sawdust into the material conveying pipe again before to disperse. Can make sawdust the moisture inside the rapid evaporation, rotating drum set in the stop can effectively clean sawdust impurities, in the sawdust into the conveying pipe can ensure the quality of the sawdust. In the sawdust into the drying zone internal spray torch and rotary tubular joint action, sawdust in the cylinder in roll vulcanization, high temperature heat sealing full and sawdust contact, and finally sent to the discharging mouth, complete the whole drying process.
