	why do we call direct dryers as adiabatic dryers and indirect dryers as nonadiabatic dryers? is it mean that we insulate direct dryers that we call them adiabatic? thanks in advance

	thanks JPool, but it didn't answer my question, it was just types of dryers in " handbook of industrial drying" by Arun s.Mujundar , 3rd edition, it says that: indirect dryers also called nonadiabatic units and direct dryers are also called adiabatic units ----- i say , direct doesn't mean adiabatic, direct means, the hot gas is in direct contact with the wet materials adiabatic means, no heat transfer Q=0 so i think if we insulate the indirect dryer, we can call it adiabatic dryer also what do you think?

	One thought is to ask a meaningful question, if a meaningful answer is needed. For example, WTF is a <...we...>, and do individual forum subscribers have an opt-out facility rather than to have to endure submergence in groupthink? __________________ "Did you get my e-mail?" - "The biggest problem in communication is the illusion that it has taken place" - George Bernard Shaw, 1856

	The forum cannot know why <...we call...> anything anything in particular, as the <...we...> is undefined and its activities and capabilities are completely unknown. If only the forum could be insulated from questions like this... __________________ "Did you get my e-mail?" - "The biggest problem in communication is the illusion that it has taken place" - George Bernard Shaw, 1856

	hehe sorry bro, no need to get angry, be relaxed and i apologize that i made you angry by using " ...we or we call... " the important thing is you understand the question, if you didn't understand, so let me say it in this way why direct dryers are also called adiabatic dryers? thanks bro :)
