Details of our open-source seed cleaning machine. (Plans are at www.realseeds.co.uk/seedcleaner.html ) We would really have liked one of the fantastic commercial machines made by Selecta or Seed Processing Holland but couldn't afford the price tag of 10,000 - 15,000 euros, so instead we made our own from scrap materials found in a skip.
It actually works very well, selecting seeds on basis of density, so you can take out for example all the thinner or empty pepper or squash seeds. It works from tiny seed like tomato up to big things like squash and sunflowers.
We've put this video up in case it helps the (very small number of) people who also might want to build one. Ok, so there aren't many of you worldwide, but if you're one of the few who do watch this video, you probably really do want one of these machines. :-) PLANS NOW ON OUR WEBSITE AT www.realseeds.co.uk/seedcleaner.html

IF YOU BUILD ONE please email me a picture of you and your machine to add to a gallery on our website. Thanks :-)
