Cool device!
If I understand it correctly, the heavy stuff like rocks falls down the vertical shaft, and the lighter junk gets sucked into the vacuum, leaving behind the seeds? Do you have to adjust the flow on the vacuum for different size seeds?
Cleaning some sunflower seed. I use this zigzag diy seed cleaner to clean all kinds of seed on the farm. It sorts out the debris and lesser quality seed from the good stuff using vacuum pressure. #grownostr #farmstr #gardening #seedstr

Yes. High density material zigzags down, while light stuff gets stucked to the other side. Nothing gets sticker into the vacuum. There is a dial vent on the back of the cabinet to fine tune the suction pressure.
