After doing a bunch of tests, we realized that winnowing was easier and our yield was better when we sorted the beans into different sizes (i.e. small, medium, large). We started out doing this by hand but it was really tedious and time consuming so we decided to build a sorting machine. It took a little while to build, but we’re pretty happy with how it turned out. It sorts a lot of cracked beans quickly and it kind of sounds like rain (chocolate rain?). Now we just need to have a better loading system and rebuild it out of stainless steel…
