Seeking a lean method to remove moisture from anodized parts





I have a anodizing client who is on the lean journey.  He has reduced his batch
size but has encountered this problem.  He needs a method to remove all moisture
from his parts without staining or otherwise adversely impacting the finished
appearance. The parts are normally batched and loaded into a convection oven at
200F for 10 to 30 minutes until dried and then removed and packaged for
shipment.  Because he has reduced his batch size, he now needs to open and close
the oven door very frequently, which releases heat (energy loss).  Frequencies
of drying  a batch per minute are contemplated.   This is counter to efforts to
become lean and approach one piece flow.

Any ideas for an alternative to the existing oven that will accomplish the goal
of drying the parts without adversely impacting appearance of the anodized
parts, but enable small, frequent batch sizes?  Air knives and/or continuous
conveyor-type ovens are possibilities.  Any experiences with these in this type
of application?    Additionally, we don't want to negatively impact other
aspects of the company such as increasing energy costs or environmental impacts.
So.... any help would be most appreciated.

Thanks,
