    Roasting ball bearings

    I had a friend call me with an issue. When he roasts he finds 1 to 3 unroasted beans. I told him to get a rubber mallet and tap the down chute when starting his roast. That maybe they are getting stuck bellow the hopper. He spoke to another roaster that suggested putting 1.5 lbs of ball bearing in the drum and turn it on. He says that it knocks all the debris free. I told him that I thought that was a bad idea. If he did do this it could damage the paddles in the drum. I also said that if the beans were trapped in the drum they would come out like charcoal when they popped free. Anyone want to chime in on this?

    There is no way in hell I would put ball bearings in the drum... I think your suggestion is logical.

    Sounds like the beans are getting trapped in the down chute of the hopper. Anything beyond that which has the proximity to fall back into the batch at the end of the roast will show some degree of "heat exposure". Curious thing what some roasters will consider putting into their roaster...ball bearings? Has anyone complained of a ball bearing ruining their grinder?? Yikes!!

    Ball bearings will also take off some of the seasoning on the drum, which will help more beans to get stuck.
