This project seeks to build a small farm-scale pearling machine. The pearling machine will have a theoretical throughput of 1,000lbs of grain per hour. I will design the machine in CAD so that when I am finished plans will be available for other farmers to build their own pearling machines. Once construction of the machine is finished, I will test it with several different small grains. I intend to figure out the settings to partially pearl grain in one pass and fully pearl grain in 2-3 passes. I will also work with project advisor Dr. Elizabeth Dyck to get grain that has elevated DON levels and pearl it to different levels. The grain would then be sent out for testing to benchmark the potential for DON reduction.
Pearled grains are used commonly in cooking but machinery doesn’t currently exist to do this on a small scale. The goal of this project is to develop a small scale pearling machine that can be run on most farms. Local pearled grains would be a unique value added product.
Lightly pearling grain reduces the cooking time.
Pearling also shows promise as a way to reduce DON content in grains and help farmers be able to market higher DON grains.
I have designed the pearling machine in CAD (Fusion 360). I will begin fabrication soon. As I build the machine, I will make blueprints for the individual parts from the 3-D rendering. I will take pictures throughout the build process.
Progress is going slower than anticipated. We have had an unusual amount of breakdowns and demands on my time this past year. That is life on a farm!
Education & Outreach Activities and Participation Summary
I will have a field day and have a page on my website devoted to this project when I am done. This has been very successful with disseminating the information from my previous two SARE projects. I have been contacted by people around the country and globe who are building spelt dehullers and compost turners based on my designs from the SARE projects.
