Aeration heat.

Now my prick attitude would say it isn't malt until there is a check in hand for a value that is reflective of malt prices....with that stuff it ain't over til it's over!

My unit is air to air. The unit showing up tommorow i dont know.
Farma, I admit sometimes it's a little salty to swalliw.

blackpowder....your last comment to me has me wondering, the malt barley game a little salty to swallow or my attitude? If you're referring to my attitude, I would prefer you use the word "bitter" to describe it....and that can be hard to swallow too. Please make yourself clear, no innuendos next time. ;-)

Be careful over drying the barley. You don't want to just add 40 degree heat or you will have 6% barley in bottom of bin and top of bin still tough.

For every 20 degree F temp rise (if my memory is correct) will cut your humidity in half.

So say you were just planning on setting temp to 100 degrees F this is what happens as an example:

Daytime temp averages 60 and you heat air to 100 you reduce humidity twice by 50%. So 60% incoming humidity drops to 15%.

Night time air is 40 degrees and 100% humidity. That drops 3x by 50% when add 60 degrees of heat. Makes air 12.5% humidity.

If you look at the chart on a standard 919 grain testor, I think the one scale is humidity and other temp. If you look at 12.5 humidity and 30+ degrees grain, you will be ultra dry.

Sorry if this is not very clear, but ideally you need to vary the temp you are drying at as humidity changes.

Continuous flow grain dryers take this into account by speeding up/slowing down the flow of grain. In bin drying can't do this unless you have a stirring system.

Unit arrived today. Diesel engine drives a glycol pump that itself heats the glycol. Flameless. Self contained unit with its own fan.
Their ducting rather smaller than fan intakes. 7hp - bottom of bin warm quick. 10hp not so much. Have to bleed in a lot of ambient to keep ducting from collapsing. Unit works well tho. Hope to be done by end of week.
