Hi Anon,
What sort of quantity are you bagging per shift and what size are your bags. The reason I ask is that we have seen a very simple, diy net weigh setup that can bag about 300 lbs/hr into 5 lb bags. Cost? About $20! More than this and your heading towards a shop bought solution.
As for the destoner, all the roasters I know collect what they find in their green bean sacks and display them so, yes, it's universal. Nails, staples, rocks. One roaster I know even found a tooth but I suspect that destoners are far more important for roasters using less than specialty coffee grade green where the number of defects is so much higher. Don't forget that the pneumatic process used in destoners might cause some damage to your roasted whole bean as well.
Let me know if you's like more information about the bagger.
