Heat-transfer simulation of slice potato during drying.
切片土豆干燥中传热过程模拟与分析

Internal heat and mass diffusion process is the base of the study on drying mechanism and drying technology. In the paper, the simultaneous moisture and heat diffusion equation with heat-moisture diffusion have been developed and used to solve simultaneously heat-transfer. The third boundary constraint model has been considered. Avoiding the man-made mistake which internal moisture diffusion models and internal heat diffusion models are divided up, internal heat diffusion is simulating together with internal moisture diffusion. Application was made and predicated results agree with the experimental data on the whole. The internal temperature of slice potato during drying isn't identical to the surface temperature during drying.
