Already have a well insulated lumber kiln, so I'd have no reason to get a shipping container.

Yea I have read that V. tech one a few times. There is also a video of it. Like the big access doors in the rear idea. Seems smart.

Hang a tarp from the bottom of the wall to the lumber youíre drying to help direct the air to flow through it versus around it. Other than that two vents top and bottom to allow moisture out and drier air in would be all thatís left to do. The one I built was similar to the virginia tech one only smaller. I think youíre biggest issue will be controlling temperature without allowing too much moisture out. On mine I just put a tarp over some the clear roof panels for the first week or so. Less sunlight hitting the black interior equals less heat. Will be much harder to control with a container but not impossible.

squarewheels Would pallet racks work (like the racking Costco uses)? Place green wood in 4x4x4 bins. Use fork lift to place on racks. Let it air dry for a season. This would significantly increase the amount of storage space and most of the cost is a one time cost.

Yes its a mess at the moment, but should have it squared away by Sunday evening...

As far north as he is, there wonít be a lot of heat gained to speed the drying process making solar kinda useless for that purpose. The talk about moisture escaping to fast was in response to the other quote which was talking about drying lumber.

Oh and STFUG

If youíre wanting to dry lumber You may have trouble controlling temperature with a container. Painted black, you should have no problem getting the temperature up. Itís when you want to keep it around 125-130 with the vents closed in the middle of summer since you just put in a fresh load and donít want it to let a lot of moisture out.



As far as cooling off, it all really depends on how much is in there to hold the heat. Empty space cools faster than the same space loaded with wood. On the other hand it may take a while to get all wood up to temperature if thereís a lot of it. The heat/cool cycle didnít bother the lumber as much as letting out too much humidity too fast.

this
there's a fuckton of tree that you can't sell as anything but mulch

someone else suggested itt a bigass woodstove inside the drying kiln
seems like a good idea, use an old 120 gallon propane tank, make the flue big enough you can drop shit in from up top so you don't need to air the building out to refuel it, make the intakes adjustable from outside (as opposed to routing them outside alltogether because you do want the air exchange for drying purposes)

Mopar Moe I was thinking waste oil as well, or maybe build a small biomass boiler that burns waste oil and waste wood (soft wood), Ive seen a few simple systems that utilize gravity fed waste oil into a large heavy plate steel wood stove with a blower...

It's designed for low heat, slow curing, for lumber. Around 100-120*

I am trying to dry firewood. It works for that, but the load we tried took 3 weeks and $600 of electricity.

If I had a way to heat the kiln to around 200-220*, it'd take about 3 days to dry.

Electric heaters would work, but at .20 kw/hr it's expensive.

Thinking of a diesel fired heater, like a Frost Fighter or a house furnace.

Dunno how well it'd work though.
What's your cost per gallon of diesel or fuel oil?

3 GPH x 24 hours = 72 gallons per day x 3 days = 216 gallons of fuel per load.

Looks like marine diesel's $3/gallon there - that'd be ~$650 per load for energy.


1/7th the lead time may justify the expense, but include your energy costs & machine amortization into your cost per load.

I found that my cheapo outdoor temp reader from Walmart will max out at 151 degrees so I donít know how hot it gets in the summer. The only problem with solar is the heat and cool cycle having to bring the load up to temperature everyday.



If he keeps the load light in it it will likely work fine. Still will take a month though at least and wonít fit his timeline of wanting it done in a few days.

nate379 In the area of about 400 cords a year.

This is the first year doing seasoned wood. Before that, it has just been that the customer deals with drying it... usually by buying in advance.

I kept rough track last year of all the inquires for dry wood (typically fall and winter) and decided to try it out. I have about 18 cords I have drying from this spring and that took up all the room I had.


The space that even 50 cords would take up just isn't going to work out, plus it'd need to be under a roof. We have about 3 acres and it's pretty well taken up by equipment, buildings and log piles.
And it's tough to predict how much would be needed.

If it works out well, probably will setup with a commercial firewood kiln, but at this point not going to shell out 20k just yet.

I have 18 solar panels on my roof at the house.

They don't make much power from Nov-March.

Neither of those is something that exists around here, at least not in any form that I would trust using now.

Plus putting in a steam plant would be a headache with insurance I think. Vs a std home heat wood boiler.
