Thank you! The flavours have improved considerably since the redesign, I got it right after testing four different drums. The beans are more even roasted now, and the degree of controll has increased significant.
Sverre Can you please explain to me what material you used for the drum? also the thickness? The first prototype you sanded the drum and then burned it with oils etc, is it just normal metal or did you use stainless steel? Then on this subject did you use stainless steel for the whole construction or did you use normal mild steel that you then polished?
Yes, BT = Bean Temperature, its a temperature probe placed so that its "covered" with beans, giving a estimated reading of the exterior temperature of the coffee beans.
Thank you! There is a manual damper, as you can see on the side of the hopper, to control the airflow. The chaff seporator and collector is basically what the fan is resting on. I will keep that in mind! Im working on the new design now, the overall footprint will be reduced, and so will the weight.
Thank you. It would be a lot easier for me if you could ask some more specific questions for me to answer. And please don't toast your coffee, roast it instead!
Good nights, graces for taking a time to answer me. You can send the information of design, for the construction of the prototype of the machine of roasting coffee, I want to make one, since to buy it new me is costly. Thank you
Great project! Thank you for sharing. Could you please explain the drum construction? What do you have inside the stainless steel pipe? How do you mix the coffee? Is there a rotating fin on the full length of the pipe? Where is the heater, what type of heater you are using, and how is the heat conducted to the coffee?
Inside the pipe there is 10 fins that pushes the coffee beans in different directions. That mixes the coffee and pushes it out when you open the front door. Yes, it goes through the full length. The heating element are directly under and on the sides of the inner drum, or pipe as you called it. Goes the entire length as well. It's conducted through the drum wall and the air that is been forced through the coffee roast by the big fan at the back.
+Sverre Simonsen Firstly, this is super impressive, so thanks for sharing. When you say that it goes the full length, does that mean that the beans are being pushed all the way to the back of the drum and then forward again? Also, how do you remove the chaff? Do you use a cyclone separator?
In your first prototype I saw you took out the chaff from the top of the funnel, how do you get it to go there if I may ask? Great job and am on putting something on paper also, will be building mine in Kenya
Yes I am also wondering about this, also I see in the second prototype you are using a different fan system... Please can you give me more info as this as I want to start building my own! By the way excellent work this is inspiring!
Good nights, I am interested in constructing a machine to roast coffee like that you have published, this is for a personal laboratory to analyze the coffees of my region. Udted can give me the technical or flat information for the construction of the machine. Regards and successes.

Great video! Would you ever consider publishing the design online so people can try building their own?
Great ! I did not see the silk shell of coffee beans separated from the seeds. That could make the coffee cup scorched
That is seriously impressive!
Great build
Great! how do you design the front door to don't broke the beans while the machine is rotating? thanks!
Great project!
great work, can you give me th e detais about the chaff collector? motor speed, air flow, etc. Many thanks
Pretty amazing work!

Hi. Do you mind sharing the design
this was so cool. Nice work!
Great job. This is a really nice roaster. Nice and compact and super functional. What size is the drum if I may ask?
Your roaster is to cool!
Du you have some drawings, you would like to share with me? or is it a Secret?
I wanna build one, and i need some ideas.
Great project! Thank you for sharing.

Could you explain what you mean by BT Temperature? I'm assuming bean temperature.

i want one!
how do i make it?
How much did it cost, and how many hours did it take to make this roaster?
Hello Sverre Can you tell me what software you are using to control the Roasting operation. Very nice work on the roaster. Well done
Yes, it's called Artisan. It's free.
Hi! How much did it cost you to make this? Do you live in Norway? If so, where do you get your green beans from?
Don't know the cost, but it took many hours to build. You can contact us at sales@roestcoffee.com for green coffee information

Can you make me? How much it is?
