very nice!
Hi, you could also try weighting the rejects vs the ones the went through on a digital scale. As you said, size is not an indicator of density, as this is what your separator does, separate seed based on weight.
seperation on density actually, which is often related to seed quality, as opposed to weight.
@@realseeds750 @Real Seeds I don't see how this contraption could distinguish volume to separate based on density. It is the weight regardless of seed shape that causes the separation.
@@dietrevich no problem to explain: the seed falls downwards with a force due to mass (gravity), against an airstream that is moving upwards, which exerts a force (wind resistance) based on the cross-sectional area. The net force therefore varies with density of the objects, giving a density-based seperation.
So it can seperate identically sized seeds some of which are less vigourous (more hollow due to less endosperm and therefore less dense), but cannot seperate a mix of all good but different sized full seeds as they are all the same density.
Thank you for sharing. I assume you purchase your seeds from Mum’s ?😎🇨🇦
Yes - and the Italian seeds are consistently inconsistent...
Agreed. I would like to find another source in Canada but have not found one.
@@paullemay3218 I'm suffering from this same seed... This would definitely change the price of my sunflowers, as I would have to add the time it takes to do this and clean this machine.... It's a good idea, but consumes space and time.
How did you go about cutting the wedges ?
