Hi Sam - there are several that have been experimented in within the community but a tool wiki has yet to be created to document them. Your post is a good reminder to get it done! I have the expeller screws which I have been hoping to scan as a 3D model for folks to share and study, but i have not done it yet. The most common around here is are the small Anyang (AGICO) Chinese based presses and the German kernkraft. I have most of my experience with both the 1 ton/day and 6 ton per day chinese models pressing sunflower and canola - the models I have worked with came from http://www.ayimpex.com/Oil-Milling-Machinery/6YL-Series-Oil-Press.html . The Chinese ones are more of a hack because, although they work well, are really much nicer if they are disassembled, sand blasted, repainted and repowered for 220 or US three phase - which is worth doing when they start out at 1/4 or less of the price of the others. I think i got my first one for less than $1000 delivered to the US. You can see a nice comparison of European models in a review done by UVM of small scale presses. here: http://www.extension.org/sites/default/files/2014%20-%20Callahan%20et%20al%20-%20Small-Scale%20Oilseed%20Presses.pdf Happy to answer questions, and help with documentation!

The broken link is noted (looks like it is broken on the home page but not others). Thanks for the note about the logo. Here it is.

The base column was purchased from http://www.turnerbiodiesel.com/ but was then modified so that it could be rotated and reversed to backflow the filter media and also facilitate cleanout. I can post more images of the quick connects and frame that make that possible.

The polishing column takes excess methanol and soaps out and substitutes for a water wash. The advantage is a savings in time, and elimination of the waste water issues. There are several available absorbent materials available on the market. The material I use is based on refined hardwood chips. Thank you for your inquiry. I am happy to post additional documentation that you would find useful including process flow diagrams, bill of materials and more detailed component photos.

I used some file conversion plugins for solidworks and posted the part to 3d warehouse here: https://3dwarehouse.sketchup.com/model.html?id=ud1172048-8b7e-45d0-941e-db0679f61db1 Also uploaded in in dwx and exported to dwg
