While waiting to complete my new fluid bed roaster I have been tempted to push the KKTO a bit harder to see what it can really do. My demand is such that I really need extra roasting capacity now! I have pushed it up to 1.2KG greens to give me 1kg roasted! Mine is modified with the thermostat bypassed and just the heater switched thru the handle and perforated plate on heater removed. To my surprise it handles it with ease, roast length is obviously a bit drawn out, but it only needs a burp to get over first crack and then a few burps thru the time between 1st and 2nd crack to maintain the RoR i want. I am getting a lovely decreasing RoR thru the whole roast and getting around 25% development time as per Rao. Beans are actually more evenly roasted thru the whole bean as a result and the taste in the cup direct from the roaster was amazing! I think mentally I always held back from pushing bigger loads because I was concerned about the roast time being too long, having broken that barrier was an interesting epiphany! Its amazing to think what this marvellous invention from Paul is capable of, a 1.2kg roaster that cost under $800! The new fluid bed, Rocquette Roaster has a lot to live up to, but if it can match the KKTO for roast quality and punch out 2.5kg roasts then it will be a success.
