Dryer working principle
Aug 29, 2016

Drying process requires a large amount of heat, in order to save energy, some material with high moisture content, containing solid substances in suspension or solution is usually by mechanical dehydration or heat evaporation, drying in the dryer to get the dry solids.

Need complete heat in the drying process and quality (wet) passed to ensure the material surface moisture vapor partial pressure (density) above wet-steam-pressure in the external space, ensure the heat source temperature is higher than the temperature.

Heat from high temperature heat sources in a variety of ways to the wet material, material moisture evaporation on the surface and escape into outer space, to differences in the surface and the moisture content within the material. Internal moisture to the surface diffusion and vaporization, material moisture content decreases, through the drying of items as a whole.
