Great! I will add this to the tool template wiki right now. One thing to add is that in the embed code if the width="100%" rather than a fixed pixel width- then the spreadsheet fills the available horizontal space- which can make it easier to read too.

Here are some images of approaches we use on our farm - everything from the screw in "pencil" dryer fans to drying outside or hoop structure on tarp up to 10 tons. If you have the weather and the quantity isn't that large - it is a very fast and economic way to get grain dry, and is not much labor. We have also used a small bin with a screen bottom and fan (Image is of Cayuga pure organic's dryer). I agree that it would be good to post sources for the bottom screen and fans. I have also heard of using drainage tile inside grain wagons or bins (prior to dumping grain in) used with the pencil type dryers or other fans. I have not had to try that yet, but expect I will at some point.

Here are some more photos which may help explain how it works - I like the idea of an eccentric axel - but would be great to have it function without hydraulics. That is one of the nice things about this design is that it will function even if you don't have a tractor handy. here is a video of a similar design in action

Yup - part of GreenStart's mission is to make its work open source - and we have a focus on documentation this year. I think a Farm Hack event would be a good idea - probably mid-summer. There are a number of tools coming along that would be fun to work on- including a new roller crimper inspired by the ADA bio folks that I am particularly excited about.

Funny you should ask about more documentation. There is a LOT more documentation coming for this tool really soon. I have detailed process flow diagrams, parts lists with major suppliers and will be doing a video with operational instructions which I hope to complete this summer. I also have performace data and will be able to post the arduino based temperature data logs up and running again in its new fancy enclosure. I will also be building a new modular processor which I will swap out for the existing static mixer/tank. This change should drastically reduce the price of the whole unit by eliminating the need for the co-generation unit for heating the oil and running the air compressor. The new unit will be a smaller diesel direct drive air compressor and hydraulic power unit to run the air operated pumps and two metered hydraulic drive pumps for a cavitator type processor which should work at ambient temperatures. Thanks for your interest and will post more as soon as I can! It would be great to see this system built at different scales and variations.
