Farmroast, I've seen your roaster linked off messages in other forums and have always admired the design. Great job! Rick |

Member Posts: 2 Location: Joined: 15.08.07 Posted on 08/16/2007 00:33 Edit Quote I read and reread all the posts about the DreamRoast" 1kg+ Coffee Roaster and found your roaster absolutely fantastic! Question: as it is now, would you recommend or would feel comfortable to recommend anybody to build one? In other words, to clone it or you already made some little/big changes since the first post? I live in Costa Rica and it is out of question to buy any roasters (domestic) and have it brought here! If it breaks, fails or need adjustment (unlikely but really possible), it will be a pain in the neck to send it back for repairs:red tape, costs, time frame and so on! Thanks for any help/advice!

I have to chime in with kudos for the chaff removal slot idea also. Consider that idea appropriated s:1 It is so elegant. I will tell you it is already in the design of my next two roasters. Too cool. |

I'm with Mike, homeroasters are getting larger and the 1/2 to 1 kilogram size seems to be ideal. This is a well constructed found-objects roaster. What I like the most is that you have integrated all the components into a single unit mounted on its own stand making a 'roasting station.' Nice idea. To me, the downside of this design is that another person would have to find the same objects, which isn't always possible, The good thing is that it illustrates better than any roaster here just how much you can accomplish with what resources you have.

Ed N. After making my basic BM/TO I wanted to make a roaster with a bit of overkill in term of controls. It is helping me understand the science part of roasting as I have only been roasting for a year and a half. My goal is a perfect marriage of art and science (long live the theories of Les Paul). My next goal was to have the very best in roast quality. It's what ends up in the cup that is most important!!! Evenness, no hot burn spots, any roast profile desired. With the whirling action along with the convection air flow the chaff slot was born. Chaff removal during roasting was desired to increase roast quality(no roasted chaff particles sticking or off flavoring to the roast). I truly admire your wisdom and expertise. s:1 thanks, Ed B. John Thanks and best of luck with your future creations and chaff removal, Ed B. Dan For homeroasters who desired to share the fruits of their work a larger batch size seemed useful ( can actually roast up to 4lbs with an acceptable profile and results). Being a farmer(mother nature often can't wait for me to do repairs) I wanted a roaster that would not breakdown, meltdown, catch on fire or be harmful to health due to improper materials or cutting corners(as many commercial home units and homebuilts do). The concepts can be duplicated in a much more simple build but I wanted to build my roaster to last for many years. In the future I may explore a more simple off the shelf build for those who desire such. thanks Dan, Ed B. Edited by farmroast on 08/16/2007 10:18 AM |

Ed, Your one kilogram roaster is so worthy of praise and admiration. Not to take anything away from the technical design and execution of your roaster, but I just love the "Vari-Speed Solid State" plate on the front. It seems so apropos, that I don't think your roaster would have been complete without it! s:2 Me too on the chaff slot. I never would have come up with that on my own and the fact that you did and shared it with us, served the purpose of this contest so well as indicated by the fact that Sir John has already appropriated the idea. s:1 Thank you for your support! Respectfully,

Ehhh! Just you to know, finally I was able to contact Ed! We talked on the phone for more than one hour. What could we do without Skype? Really cool guy by the way! Ed, has a nice set up roaster. I mean really nice and ready to fill the gap between the home roasters and the commercial roasters. There is a big untapped marketing window for micro roasting equipment. Good luck Ed in your project! I see a bright bright future. Roger Costa Rica |

I'm thinking of building a setup like the Dreamroast. I see that you've added a PID, and I'm curious about what heat source it's connected to. I read in another thread over at coffeesnobs that controlling the element (in this case a heat gun) with a pid is problematic as the fan keeps going when the element shuts off. This makes the beans cool when the element is off. In this case the thermocouple was placed in the bean mass, which reacts slowly to temperature change. Maybe it's a better idea to connect it to the upper thermocouple, measuring air temp, in your setup? |

With the variac my heating element is always on(smoother control) and the output is adjusted with the variac. If I was looking to repeat many roasts it would be somewhat useful. The convection fan is separate and is always running but would be less of a problem than the heat gun issue as my fan is not bringing in outside cooler air but is merely circulating the air. Ed Ed B.

OK. The variac is not an option for me, as it is to big and to expensive for my taste. Are all turbo ovens circulating air? If this is the case, a PID is really not a bad idea for temp control. Auber instruments has one with programmable profiles. That would be really nice. I love your setup by the way s:2 |

Thanks, Yes the fans on the turbo tops I've seen are merely for circulating. I needed the variac because of voltage drop issues at my house as well as for temp. control. For a little over $100. I was able to solve both issues. If not using a variac the pid would be a good alternative. The placement of the air temp. thermocouple gives an accurate reading of the air just before it hits the whirling beans. Bests, Ed Ed B.
