Sir,
During the maintainence of Drying, Temperature fell down due to Steam flucutations/leakage/vacuumpump tripped. after rectification of this problem again temperature rised and maintained rest of the duration.
is this Deviation or not.
Drying for what?which process was going on.
Normally it is abreak down.but with other eye we can say it is deviation if it is a HPHV cycle(because we have to prove that all the air is pumped out if any vacuum pump problem only in the above case),not if it is gravity cycle,
