RESEARCHES ON MOISTURE DIFFUSION IN CABBAGE SEEDS WITH HEAT PUMP DRYING

摘要：

A three-dimensional nonhomogeneous dynamic moisture diffusion model was set up for cabbage seeds with heat punp drying.It is used to analyze the moisture diffusion in the cabbage seed under conditions of continuous drying with constant temperature and intermittent drying with on/off pulsating of air velocity.Results show that, with the heat pump intermittent drying, the internal moisture distribution of the cabbage seed is more uniform and nearly 50％ energy saving is achieved during the drying process.
