Simulation and test study on rotary dryers IEEE

Simulation and test study on rotary dryers IEEE

Jul 17, 2011 The research was done in the rotary dryer. It included variations of hot air temperature of entrance to the rotary dryer, moisture content of materials, rotational speed and inclination. The experiment indicates that rotational speed directly interferes with retention period of materials in the rotary dryer. Hot air temperature and moisture content of materials also interfere with drying rate ...

Principle and Mechanism of Drying Humidity Relative

Principle and Mechanism of Drying Humidity Relative

Drying is the thermal process through which liquid is separated from a solid-liquid mixture by the application of heat and also by accelerating evaporation through vacuum. The amount of water vapor in the air at any given time is usually less than that required to saturate the air. Relative Humidity is the percent of saturation humidity, generally calculated in relation to saturated vapor density.
