FEVER SUPPLY DEVICE FOR VENTILATION TYPE SPIN DRYER

摘要

PURPOSE: A hot air supply device for a ventilation-type rotary dryer is provided to increase drying efficiency by supplying optimal hot air is blown to objective materials by extending the length and the diameter of a tube heading to an inlet port from an outlet port. CONSTITUTION: A hot air supply device(1) for a ventilation-type rotary dryer is installed in a drying drum(100) in which objective materials(A) passed to a discharging port(120) from a pouring port(110). The hot air supply device blows hot air to the objective materials by using branch pipes(3) formed along a hot air blower(4) connected to an air conduit(2). A plurality of spraying nozzles(2b) is formed on the inclined plane of the upper portion of an air pipe.
