Wild Rice husking machine

My brother produced this fun video of my bicycle powered Wild Rice husking/hulling machine.

I designed and built it myself with the help of my dad. It is made from a recycled 55 gallon steel drum with sheet rubber glued to the inside. Stainless steel rubber coated paddles rotate inside the drum and rub the hulls from the grain. These paddles are bicycle powered and spin at 100-120 rpm while an electric fan blow the chaff out of the drum. Further winnowing and hand picking is required to separate the remainder of the chaff and a few kernels that make it through with their husks in place.

  1. What a great idea! I especially like the bicycle part.

  2. What type of rubber did you use (type and thickness) and how far does it hang over the end of the paddle. Currently working on a project to hull 20+ pounds we harvested. Thanks for the help!

  3. wow! This is a great invention. It must have made the task of husking easy and quick. You must spread the word about it for the ease of other farmers.

  4. I have read your article, it is very informative and helpful for me.I admire the valuable information you offer in your articles. Thanks for posting it net worth
