Rotating machinery or turbomachinery is a machine with a rotating component that transfers energy to a fluid or vice versa. Rotating machines are one of the most widely used machines. They are used in everyday life, at least once a day. We find a turbomachine (fan) in a hair dryer and in a computer. We find a turbomachine (pump) in …

A condenser dryer then expels the leftover hot air. In a heat pump dryer, the dry air that remains after passing through the condenser is recycled back into the drum where it is reused. This means that this type of tumble dryer doesn't use as much energy heating up fresh, cold air, making it by far the most efficient type of tumble dryer ...

Working of Drum Dryer. A drum rotates, the liquid material gets adhered to an external surface of a drum. The liquid is spread as a film onto the surface. The drying of the material is done by the process of steam when passed into the drum. By the mechanism of the conduction, the heat gets transferred into the drum, and the drying process takes ...

The liquid feed of a drum dryer is applied onto one or more slowly rotating steam-heated rolls. The dried product is removed by a knife-like mechanism. Drum dryers are primarily used to dry slurries and pastes. They are available in several types; single drum, double drum, double drum vacuum, and twin drum.
