  1. The science behind forced log drying

    Do many farmers deal in firewood? I thought it was mainly surgeons running this as a top up to their felling day job? Just curious really. Spoke to local chap here who has 4-5 gangs out daily, he just processes it himself on the quieter day and pushes it into a windy shed. Crickey. So call it £42 on average x 900 = £37k at 90 t that's just over £400 / ton!? Transport, processing, bad debt / tolerating the general public aside, from the outside that seems like a respectable business model!
  2. The science behind forced log drying

    Completely on my wave length. We only differ by the colour of our boilers and the fact that as mine is for my own use I don't need it processed down as small as you would. how many tons do you sell per annum? V smart website too

    Take a few on a trailer to a weighbridge, only way to be sure
  4. The science behind forced log drying

    About 300 m2 of surface space in one of ours, yet try it out but could pass air 30-40 degrees 24/7 with RH at 40%. if I stacked it 1m tall I would get loads of air flow, tempted to try half a shed and try about 75t in a batch
  5. Thanks for this. my nibbler description was poor, it's like tree shears / pincers but they have sharp points that bite into and split timber, same concept as cone splitter but different design. Pros and cons to both!
  6. That's very helpful, thanks i have been looking in to getting one, i 'only' need to break down about 300 t per annum but it's all for personal use and I am not much bothered by length or size of finished product. I am collecting it locally and then trying to get it dry hence the need for a splitter of sorts as it comes in all sorts of lumps. did you look at log nibblers instead? Did you look at any other cone splitter makes, I hadn't considered the cone angle, what do you think is the optimum angle? i have a 3.5 and 7.5t machine, prefer to use the larger unit as better reach and would assume a little quicker?
  7. Interested in the cone splitter, which size have you and on what machine? Any idea on price?
  8. How do they cope being so close

    I am having fire place envy!
  9. The science behind forced log drying

    On a separate point, where is the wettest part of a log? Dropping back to my biology lessons, I always thought the outside ring (xylem or phylum vessels) which transported the nutrients up the stem were. As the tree grew the stem expanded and the centre was retained for strength and support instead. With this in mind, surely the outside 10-20% is where it all going on, the inside would be much drier, so why the need to split!?
  10. Free timber/logs

    You are just a bit too far away from me otherwise I would have sent a lorry over to collect
  11. The science behind forced log drying

    I don't disagree all though not sure I can't get it down to 15%? Especially in the sized material I will end up with. I have the shed space to store 600 tons but it's the opportunity cost of that space which gets expensive!
  12. The science behind forced log drying

    I could but it's not very stackable, mix of rings trunks and cordwood, doubt much air would pass, going to try piling in a windy shed and review but like to plan ahead!
  13. The science behind forced log drying

    Yeah I agree with you ref the science! I know for grain drying, dry air helps, I think it helps 'suck' moisture out. my biggest issue will be breaking down what I have, trying a cone splitter but it's on a 3.5 t machine so concerned it won't be fast enough for my liking. I imagine your stuff is split for a domestic stove I am burning in a commercial boiler that can take wetter logs all though there will be a (yet to be found) sweet spot between cost of drying vs extra heat output? I have done all my calcs on 2500kwh @ the meter which I hope is going to be much lower than reality. trying to keep cost down by only moving it around by walking floor which will take some logistics!
  14. The science behind forced log drying

    That's impressive, thanks. as none of mine is caged up I will struggle to move it in. I do have drying floors but I cant get the temperatures you can, I could spread approx 160m3 1 meter deep on the floor though? Air temp would be 30 degrees tops but air RH about 30-40. I would not get the air flow you have but it would be 'a strong breeze'! Could you see this working? I only need it down to 25-30% though
  15. I am considering trying this for my own consumption and want to learn more. Looking to dry about 300t per annum i am assuming the 3 main ingredients are heat, dry air and surface area? I can do two out of three but can't easily get the air temp above 35/40 Guessing most on here have containers converted with fans in front of heat exchangers? How long does a batch take to get down to 25/30% and how many kWh would you need? What air temp / RH are you producing? all advice / tips very welcome!
