Figure 6 (a) shows the rate of moisture removal and temperature of Nylon-6 for all the three trials. During 6
hours of dying period temperature of Nylon-6 pellets varied between 50-60oC. Temperature of pellets increases
initially then it attains maximum temperature at noon and again it starts falling during late afternoon. This behaviour
of pellet temperature can be explained on the basis of solar intensity and air temperature. During 6 hrs of solar drying,
moisture content of 100 g of Nylon-6 pellets were reduce from 0.82 to 0.15% on dry basis. Drying of Nylon-6 falls in
the falling rate period, which is clearly shown by drying rate curve (figure 6(b)). All the three trials shows results are
highly reproducible.
