Aeration heat.

Renting a 700,000 btu diesel heater tomorrow to try and pull 3 points out of 2 barley bins at once tomorrow. Claims I'll have it in less than a week if keep incoming air close to 40. Maybe shutoff at night. I know the bin size, floor type,fan size, grain height all make a difference.
Anybody used these heaters?
They also have 1.4m btu units.
Cant mention company name on here.

Redland had something similar from Bourgault I think it was on 10000 bus hoppers seemed to work.

Also a cousin uses a similar system heats the air going in.

We use a continuous dryer thats the best. Harvest tough its dry in the morning when you wake up.

Bought a blue one a few years ago pile of junk. Had a plumber friend set inches of water column n crap. Still brutal pissy little flame next to impossible to lite phoned them they said too much static pressure in bin it was only half full. Could try renting a 500000 btu frost fighter and run ducting to inlet. Just dont tell em what your doing with it lol.

I bought and Air-o--Don heater and a big propane tank. Basically a big propane furnace. Ducting goes to the fan. It's a bit of a wrestling match to put the tube on the fans but otherwise it works well. It cycles up and down like a furnace so not always immediate heat. It has a few quirks but so far so good. I have opi moisture cables in the bins to tell me what is happening. I am satisfied it works good for a one man (gong) show.

I have a 500000 air o don on NG. Works well. Just too small for what i need this year. The post fan blue ones are too small and unreliable to be worth taking home. Too many safeties too difficult to keep open flame behind fan. Ill sell you mine.

I think you would have to be careful drying malt barley with a batch or continuous dryer. What is the maximum temperature you should use before damaging the germination, stay well under it if you want to ensure the least damage... even if it takes a lot longer. Not an ideal situation.

Good luck blackpowder. What pisses me off is all the blowing and turning and handling or drying you will do and no one is willing to give you an extra cent for your efforts.... just being miserable again I guess! I SINCERELY hope you don't run into any rejection issues after all you are going through to try to ensure quality is maintained.

Farma lots of malt dried in this area, all kinds of dryers, even at the elevators. Just keep air temp about 130F, grain temp under 115F. Seems to work.

[blackpowder]

Thanx. Feed price here $2.80.

Blackpowder are you referring to a 700,000 Btu/Hr unit that heats water and circulates it through a heat-coil/rad?

Or does this a burner that heats air directly?

[Oliver88]

140F is the temperature I heat to not heat malt above to affect germ.
