You need to have data to support how long that heel can remain in the dryer. Sixty kilos sounds
like a lot to consider carryover, but you may be talking about a very, very big dryer. So that’s a
specific question that’s hard to answer in general, but the general answer is dryers are one of the
areas that you want to be careful because the material that is left and carried over is subjected to
repeated heat ups and cool downs. But once you have the data to show how many heat ups and
cool downs your product is stable through, you can leave material in there and carryover to the
next batch based on that data.
