Abrading machine

A seed dehulling device comprising:

• body means defining a cavity, said body means including lower wall means for collecting dehulled seed, said lower wall means including an outlet, said body means further including an upper wall means overlying said lower wall means, said upper wall means including seed inlet means;
• means for supporting said body means;
• means for feeding seed to said seed inlet means;
• a rotatably driven disc disposed in said cavity, said disc having an upwardly facing abrading surface, said surface being spaced downwardly from said upper wall means;
• means for rotatably driving said disc;
• and
• means for adjusting the spacing between said upper wall means and the abrading surface of said disc, said adjusting means comprising means for elevating and lowering said body means, whereby said spacing is sufficient to provide repeated rebounding of seed kernels between said disc and said upper wall means, and whereby said adjusting means provides control of the amount of working of said seed kernels.
