Abstract
In the 1st report, the drying model of a wet sheet and the formulation of drying speed, expressed as a function in the drying factor, have been discussed on a multi-cylinder dryer section. For the practical use of the drying model, three items are studied.
1. From the experimental result of canvas drying in a laboratory scale, a simplified formula, delivering variations in water contents of a canvas, is obtained by a vapour removal roll.
2. The pocket's moist condition is determined more accurately by solving the equation of heat and mass equilibrium.
3. It is proved that in a comparison between the computed value and the data in an operating condition, the drying model is available for actual simulation of water contents and of temperature distribution in a wet sheet and canvas.
