Safe drying temp for seed wheat.

[David.]

Have couple loads of wheat that I probably should bring down a bit from 18.5%, for home saved seed.
Mecmar mobile drier would usually burn up to 47C grain temp to reduce this to 13.9%, with a max plenum air temp of 103C for normal feed grain.
What settings would anyone who regularly dries seed grain use please.

I also use a Mecmar, and mostly for milling or seed I've used these settings

90 plenum
43 grain

This would normally allow me to scrape under 15%mc, I've found that the plenum temperature tends to run over to about 93/94 when on the larger jet

I have a old master grain dryer usually dry wheat at about 105 air and 46 grain. This year I dryer down my seed corn. I used the same jets but turned air temp down to about 70 and then tested it till it got down to 15 %. I sent a germination test of and had heat damage but was still 88% germination. So you may need to but smaller jets in and reduce air temperature down.

My Book says ( And I don’t have my book to hand ) 65-70 C Air for seed. Same as for malting Barley.

I am set at 85C for Milling Wheat.

You could Google it.

We are at 65 for seed/malting.

Thankyou all.

Absolute max 60 for seed crops.

What, plenum air temperature? That would make it a long, slow job?

It is.

Surely malting barley would be the same to preserve germ %?? I have dried it a lot hotter than that and still got the required spec for malt??
