PIPE DRYER

One of the most widely used drying systems is pipe drying and is also known as duct drying. The large surface area for heat and mass transfer and the high convective heat and mass transfer coefficients, which take place at these units, result in high drying rates and as a result, high drying capacity. Pipe-type drying system is used for drying for sawdust, flour, powdered coal, such as bread crumbs. Pipe length, pipe diameter, flow rate of the fan, the fan pressure, drying air temperature is important for drying. Pipe-type dryers can be made between 20-200 meters.

The simple pipe dryer system includes eight basic components: the heater, the wet material feeder, the crusher,burner,drying pipes, the cyclone, the bag filter and a exhaust fan.
