In a sizing of a spray drying: i. Estimate the dimensions of a drying chamber for a spray dryer that has an output of
1000k(g)/(h)of a heat sensitive biological material at
60\deg Ccontaining
5%moisture and having a mean particle size of 100 micrometer. The feed contains
40%solids by weight in an aqueous solution at
4\deg C. The inlet air has a humidity of
0.01k(g)/(k)gdry air and is at
150\deg C, while the outlet air is at
80\deg C. *Assume the specific heat of the dry solids is
0.3kca(l)/(k)g.\deg C
