typical wooden floors, works ok.
that's very hot. I am still experimenting but thought a cooler temp but lower RH would work ok as grain doesn't sweat so like your linseed does.
just need some wet grain to play around with now....

The wheat hasnt sweated this year as we can stir that as it's at 12ft deep. Stirring linseed with a manual stirrer would be impossible I would think.
With regards to RH, if you have intense heat you almost take it out the equation. With the boiler running chat we can hold temp 24/7 irrelevant of the RH. The boiler just works harder when it needs to to maintain the desired temp. If it drops below then the whole thing shuts down automatically then rings us up to tell us.

Are you just using 1 straw boiler ? Or 2 linked to maintain a constant temperature ?
Anybody got a drawing of typical floor construction for a drier floor ? Seem to cost a fortune for what they are , anyone know where to buy the metal vented flooring ?

I saw this at lamma & like the look of it, you lay it over steel beams

Just one. We looked at two boilers initially though. Running one 24/7 maintains heat well enough. The issue is the fuel feeding system as this is where the stops occur. Good quality dry rotary combined straw causes very few issues. We are drying bales at the minute and running solidly it's stopped last night which was the first stop since Christmas. Took 15 mins to clear and it's running again. The stop is generally the shredders grabbing hold of a wedge instead of picking at it. You almost need a prechop on the baler but these are silly money (krone) so we are looking at a mobile shredder to shred all product into a hopper and bulk feeding instead of bale feeding.
I looked at an identical system yesterday but with wood chip and it is less hassle but the fuel is 3 x the cost minimum depending on quality.

We fitted this but at a much narrower spacing so we could dry any materials not just grain.

And how did that work?
Looks really good and easy to install , did you buy direct ?
Is your straw one auto feed ?
What is a rough cost of that ducting if you dont mind me asking?

No it was part of the boiler package

Would twin wall, perforated drainage pipe do the trick?
Would need to be flat on top or , would be a nightmare to sweep up , and wouldn't be strong enough

I thought the pipes could be put on top of an existing concrete floor. Just move them out of the way as you empty the shed.
Oh understand , probably would work , but just not an ideal solution

Ye I know , was just thinking about it , could make main duct out of 600 diameter with 200 tees at 1 m centres , think it would work well
