The Winnow Wizard Developed by Mark Luterra Features:

  • Wide adjustable range of wind speeds for seeds of all types.
  • Vibrating feed tray with adjustable angle and slot width for different seed shapes and sizes.
  • Hopper holds up to 12 gallons of seed, with sliding gate for slow-feed, accurate winnowing or fast-feed, rougher winnowing.
  • Hopper support (along with hopper and feed tray) easily removed for manual pouring of very small lots or non-flowing seeds.
  • Seed dividers rest on ruled rails; the optimal setting for each seed type can be dialed in and repeated.
  • Two dividers and narrow bin can split the seed stream into three fractions: good, mixed (for re-winnowing or further processing), and trash.
  • Hopper agitator allows dirty, dusty, or papery seed to feed automatically from the hopper.
  • Magnetic hopper gate (optional) uses powerful rare-earth magnets to deflect dirt and rock particles out of a falling stream of seed.  Works best with small seed, and efficacy may vary with magnetic properties of local soil.
