The drum dryer is a cylindrical rotating drying machine that is commonly used for drying various materials, such as sawdust, wood chips, and grain, among others. The structure of the drum dryer is relatively simple.
The drum dryer consists of a rotating drum, which is supported by a system of rollers or bearings, and is usually made of steel, stainless steel, or cast iron. The drum is inclined slightly to the horizontal, which allows the material to be fed into one end and discharged from the other end.
The drum dryer also has a heating system that is used to provide heat to the material being dried. This heating system can be powered by a variety of heat sources, such as gas, oil, or electricity. The heat source is used to heat the drum, which in turn heats the material inside the drum.
The drum dryer also has a system for removing the moisture from the material being dried. This system typically consists of a fan or blower that draws air through the drum and carries away the moisture. The moisture-laden air is then passed through a heat exchanger, where the moisture is condensed and collected in a separate container.
