抄録
A series of food models containing different amounts of water were baked at around 200°C. The effect of moisture content on the heat transfer between the hot air and the surface of each sample was investigated in terms of the internal heat flux.<BR>The rate of internal temperature rise of the samples during baking decreased with increasing moisture content, the opposite of that in a steaming or frying process.<BR>The heat transfer coefficient and Biot number tended to reduce with increase in the moisture of a sample from 7.1 to 48.7%. This may have been due to the latent heat of vaporization of water on the surface of the sample.<BR>The internal heat flux during baking, however, increased with increasing moisture content. The thermal diffusivity increased from 0.65 × 10 -7 to about 1.0 × 10 -7m2/s with increasing moisture of the samples.<BR>The heat exchanged between the hot air and a sample during the baking process was characterized by the vaporization of water which resisted heat flux from the hot hot air into the inside of the sample.
