A wet solid of 100 kg containing 30 wt% moisture is to be dried to 2 wt% moisture in a tray dryer. The critical moisture content is 10 wt% and the equilibrium moisture content is 1 wt%. The drying rate during the constant rate period is 10 kg/(h m2). The drying curve in the falling rate period is linear.
If the drying area is 5 m2, the time required for drying is ______ h (rounded off to 1 decimal place).
Note: All the moisture values given are on dry-solid basis.
If the drying area is 5 m2, the time required for drying is ______ h (rounded off to 1 decimal place).
