Hi! Looking for a legacy inlet temp sensor on 13 yr old Gene Cafe. It seems they've changed it and now you need new mother board and new sensor. Any ideas where I can find compatibile old one? Mark

Grading green beans

1 1/2 Pounder Posts: 1306 Joined: September 30, 2016	I am removing small/broken beans using a drum made from wire mesh, 5x5 square grid, with 1 mm wire, thus 4x4 square openings, which equates to about 12 grade. 20 RPM rotation speed, 300 grams a batch. Is not a custom build, actually is a Deichmann Roestmeister, used as grader too

To grade beans the pull a preset quantity of beans then pour them out on a table. Then they count defects. even the highest grades are allowed a few bad beans. This was only for quality not bean size. The class to really learn this is the C Grader class. All you need in life is ignorance and confidence, and then success is sure. Mark Twain
