Psychrometrics tips?

Perhaps a bit technical, but I've been trying to solve a
psychrometrics problem for quite a while now.
It concerns a dryer in which a substance is dryed by air. The
substance is added and removed continuously. The air is cooled
between states 2-3 and heated between 1-3. The drying chamber is
between 1-2, and is considered adiabatic.
State 1: T1 (dry bulb) = 65C
State 2: relative humidity = 85%
State 3: T3 (dry bulb) = 2C, relative humidity = 100%
Pressure is constant at 1 bar, airflow is 10kg/s and circulates in a
closed process.
I'm trying to sketch the process in a Mollier-diagram; Any tips/ideas
on how to determine the temperature at state 2?
Thanks!
Kan
