hope this helps..
oh I just thought of another one...depends where you are located though. I have a friend who is selling all of his equipment. He has a mixer in is inventory.
I had and go back and read the original post. I thought he was looking for a drum to blend flavors into the roasted beans, but I was mistaken. That's what I get for speed reading through the posts.
I got the same machine topher listed at Home Depot for about $100 cheaper than Grainger, had to have it shipped to the store and pick it up. But, $100 is a $100
Thank you guys. Home depot does have it online...surprisingly enough. As for Using the roaster itself to blend, I have had it suggested to use the cooling tray while roasting, but this could get hectic and problematic if not timed right. I could use the drum before I heat it up, or on days I don't roast. But I think for speed and safety safety's sake, having a designated mixer would be the preferred method....or just keep doing it by hand. Thank you all for your input.
