I purchased a commercial restaurant blender off Ebay. The grinding blade
comes off with a screw. I made a blade from a piece of rubber belting about
3/8 inch thick and carved it like a blade. I have an AC voltage control and
reduce the AC to about 60 volts. I can load a quart of seed with the
mucilaginous seed casing on (persimmon or pawpaw) and water then turn the blender on.
In about 2 minutes the seeds are free of their casings while the seeds are
in tact. The seeds are heavier than water while the casings tend to float.
Add more water, simply pour off the casings. Rinsing about twice more and you
have seed ready to be put to bed in the frig. (stratify).
I'm getting ready to clean about 10 pounds of persimmon seed and casings
yet this afternoon, having put up 21 pints of pulp last night. Then will do
the pawpaw seeds from making 2 gallon pawpaw pulp this forenoon.
