How does Hot air drying progress?

The case of hot air flows parallel to the material (co-current) In order to contact a high temperature hot air near a material entrance, a drying speed is large and decreases to urgency after that. Since material contacts a high ...

Unit area (A) x Unit time (s) The amount of evaporation of moisture (em) is defined as Constant drying rate (Rc). This means not being dependent on material and being dependent on the temperature, humidity, and speed of a hot ...

4-3-1.Features of the hot wind heat source Dryness with constant temperature and humidity of a hot wind is called the constant drying condition. If the temperature of a hot air is changed, the relative humidity and specific heat, density, viscosity, ...

Temperature and Humidity of the hot air is called the steady-state drying conditions drying constant. 4-2-1.If wind velocity of a hot wind is enlarged, a coefficient of heat transfer will also become large. Heat transfer coefficient of the dry conditions ...

Check the performance of the air and nitrogen as the medium to be used in the hot-air drying. 4-1-1.The role of air Air at room temperature, the atmospheric pressure will behave as a nearly ideal gas. Density of air ρ ...
