Mass Transfer
In case of steam distillation, the steam leaving the liquid is not completely saturated with distillate vapour, because

Temperature is less

Mixing of steam with the material being vaporised is not so intimate as to result in equilibrium condition

Total pressure is less

Saturated steam is used for steam distillation
