JHCCoffee Thanks for the guidance.
So to roast 1 lb, it would take 50 minutes?
I consume about 1 lb per week and like to rest my beans at least 2 weeks, so am I right in saying it would require 100 minutes (almost 2 hours) to produce two 1 pound bags? That’s a lot of time. Am I missing something here?
I think I responded to the original post saying there was no way you’d get a machine with the features you want in the price range quoted. You’re looking at about £6000 for fully automated profiled roasters capable of producing a decent batch size.
I have a Dalian Amazon I’ve hooked up to a computer that can control the heating element. It’s possible to go one step further and control fan and drum speed with further modifications…..not that I’d really want to. With some work I’d be able to make the computer automatically make the adjustment to the heating element to maintain a profile, but I just use it for recording the roast and manually modulating the power to the element as I would if I were using a potentiometer. The total cost of the mod was just over £100 - those special SSRs are expensive.
The Dalian takes about 20 minutes to heat up and a further 20 minutes to roast, you have to stay with the machine as it cools down and make sure you perform maintenance - cleaning the chaff collector, cleaning under the cooling tray, applying lubricant to bearings eventually etc etc. You shouldn’t be leaving a roaster unattended at any point so whatever you do you’re going to be spending about an hour roasting + maintenance on top of that.
If you’re looking for air roasters like the Ikawa, Kaffelogic etc I don’t really see what makes them worth the price. There are plenty of air roasters out there to choose from. The selling point f the Kaffelogic is the profiles you can download but it’s not something I’d be interested in. Not really sure what the selling point of the Ikawa is, I think it’s that it’s portable and can be taken to farms….not something that home roasters are going to be doing. I’d say look on Alibaba and check for reviews for anything that you find interesting.
