When we chose our roaster there were a lot of considerations. One of the big ones was availability of parts if there were every a need for quick repairs. This is one of the reasons we went with the all-american made, Deidrich IR-3.
Since we're still a very young company we started with a smaller roaster. When everything is running smoothly we're able to roast more than 150 pounds in a regular work day, so it's currently serving our purposes well. But we sure do look forward to the opportunity to upgrade to a larger roaster when this one can't keep up.
