Drying wheat from 19 percent moisture down to 13.5 what temperature is the highest I can safely use and still preserve good germination. Running at 190 f at the moment and putting through 600 bu an hour. Thanks.

I take it you mean 190 F air temp....which should be OK, but grain temp is the most important, correct, and what are you getting there?

Don't let grain temp go over 120.

Why do you want to dry seed wheat down to 13.5? 15% moisture will keep just fine if its been dried and cooled properly. Far less chance of damaging wheat with respect to germ. etc. when handling at 15%.
I definitely would not go higher than 190 F.

Our dryer manual says plenum temperature should be maximum of 150 degrees and the maximum grain temperature should be105 degrees for seed. This is in a circulating batch drier which I would think would be easier on the seed than a fixed batch.

I agree, did lots of malt barley at 150 degrees max plenum. Using a Farm Fans batch. Germ was always fine. Seed would be similar.
