    3.1 Principles of hot-air drying

    The product is characterized by its geometry (characteristic dimension L, exchange surface S for its mass m), by its average water content X¯ (kg water/kg DM) and by its temperature θ P (of which θ Ps on the surface). It is placed in warm air A characterized by its temperature (θ a > θ Ps ), its relative humidity ϕ a assumed to be low, and its relative velocity...
