Small-scale Thresher

To make a bean thresher for WSU’s bean project, we modified a chipper-mulcher, as designed by Allen Dong and Roger Edberg, I-Tech, PO Box 413, Veneta OR 97487. Figures 4–7 show our thresher and include motor specifications that we have used.

Hammers of thresher are bolted together

Figure 6. Mesh keeps the plant material within the thresher until it is small enough to pass through. Smaller mesh would result in more finely chopped material while larger mesh would result in larger chopped plant material
