         [0088]    The inlet and the outlet temperature can be modified if necessary according to the equipment, gas or some other experimental parameters. For example, as is known that the outlet temperature can be determined by parameters such as aspirator speed, air humidity, inlet temperature, spray air flow, rate of feed or concentration. Therefore, the outlet temperature would be determined by one skilled in this art through modifying the parameters.

       [0123]    According to “Chinese Pharmacopoeia”2010 edition, proportion II, XI X J.
 
1) Keep a dry glass weighing bottle with stopper (external diameter: 50 mm, height: 15 mm) in 25° C.±1° C. of thermostatic drier with saturated solution of ammonium chloride or ammonium sulfate placing on the bottom, precisely weighed (m1).
 
2) An appropriate amount of sample was spread in the weighing bottle by a millimeter thick, precisely weighed (m2).
 
3) An open weighing bottle and lid were kept together in environment of constant temperature and humidity for about 24 h.
 
4) Lid the weighing bottle and precisely weighed (m3).
 
         [0000]      weight gain ratio=( m 3− m 2)/( m 2− m 1)×100%
