Drier temp for seed.

[David.]

I expect i have asked before, but what is max safe air/grain temp for seed crop please.
Run Mecmar at 98*C air 47*C grain to dry to 14% usually.

Too hot for seed. Typically I run the air intake at 50-60°c with a max grain temperature of 36°c.

Bloody hell you’ll cook it at that what he said^

Would barley at 18% be OK for seed, spread thinly on a concrete floor, no deeper than 6", turned now and again ?

If it's Winter Barley, it'll only be a few weeks until it's drilled, so I'd have thought that would keep it fresh enough until then.

If it's Spring Barley (which I presume it is) then it's a long time until next March/April. Safer pushed in a heap round a pedestal I'd have thought, but the cost would soon cover the extra of buying in seed on a small area I suspect.

^^ I loaded it into a 3 ton trailer (high sided) around a pedestal and it dried it down nicely. Took a percent a day out. 1.2 kw pedestal motor so decent air flow. Big pedestal designed for 6 metre spacing so it coped well with a small trailer load and a lot less hassle than putting it through the continuous flow. Something that actually worked this year. Pulled about 6 amps single phase so just plugged in to domestic socket.

This is from my Opico book but would have though it will be similar.

We use these settings for seed and malting barley

Thanks all, did 60deg and 38deg, sp barley.
I make it 16% now cooled which ought to be fine.
Surprisingly the spillages always seem to grow when I load a lorry, and that will have been done at 98/47, just wouldn't like to risk it on seed batch...

How are you all finding the cooling side this year with mobile batch driers . Never known a year for such temp variations .

Always try to cool our opico down to between 6 to 8° between the two gauges after a minimum of 40min cooling but this year we've ended up with some batches coming out in low 60s and others at 80 , in same day just due to ambient. Had one batch the other day that was cooled for over 2.5 hours and refused to go below 80 but inlet was at 78 so hardly surprising .
