| Abstract: | Heat transfer and mass transfer are included when tobacco are drying in the redryer. Based on heat transfer and mass transfer analysis, the mathematic model of drying process is established. Energy-balance equations of tobacco in constant-speed drying and speed reduction stages are summarized. The relationship between tobacco temperature and moisture ,hot air temperature and drying time is obtained. All the conclusions are important for technics optimization, tobacco redrying, and consumption conservation. |
