Great Job. Does not look like a DIY. I looks like a legit commercial equipment.

Bro this is so amazing. I was looking at how much id have to spend to upgrade my roaster and since I already know how to crudely weld I thought id check if someone had a video series. Thanks for sharing your knowledge! I think I might take a stab at this myself!

[@malletandchisel5154]

Great job on he roaster build. 100 percent agree at the ROR is being affected by the tryer.

[@kylegreenhaw6653]

Thanks! Yeah, funny thing is it’ll do it without using the trier, but I imagine it’s pulling air through the gaps around the trier and housing. The thermocouple I used has a thin sheath and reacts to small fluctuations in temperature.

[@maycondelpiero]

Thank you for sharing your amazing work with us. I've read some answers about not having a roaster project, but would it be possible to inform some more general measures? mainly the size of the drum and the external dimensions of the roaster. I was very inspired to get out of my popcorn maker for one of these.

[@kylegreenhaw6653]

You’re welcome! Thank you for watching. The drum measures approximately 8” in diameter and 10” in length. The roaster housing is about 14”H x 14”W x 16”L. The frame and feet add about 4” to the height. Hope this helps.

The hinge assembly was made with “pillow blocks” that sourced from McMaster carr. I modified the pair that mount to the door by cutting one of the tabs off.

Fascinating series of videos, Kyle! That's the kind of thing I'd love to be able to do but I didn't! I'm using a Hottop with Artisan software as well. The ups and downs of the rate-of-rise is the same thing I get, only worse! I haven't bought pre-roasted coffee since I retired 7 years ago!

[@kylegreenhaw6653]

The hottops seem like pretty nice machines, I’ve never used one personally. Yeah, the ROR thing is kind of annoying, but I don’t pay too much attention to it. Sounds like you’re a seasoned roaster! Thanks for watching!

[@ericdahlberg238]

Really fantastic series. It's nice to see someone with skills do their work. There are a lot of similarities between what you've done here and what I build - glass melting furnaces and glass annealing ovens. Did you gear and chain in case you wanted to vary the drum speed? Why not direct drive to the shaft? Where did you source the hopper? Cheers for a great job and an interesting video!

[@kylegreenhaw6653]

Thanks again! What kind of glass are your ovens for? What sort of temperature do they see? Yes, I used a chain drive for the ability to change the gearing if needed. But I do have variable speed control. I made the hopper using a funnel I bought, but the rest is built from scratch.

[@ericdahlberg238]

@@kylegreenhaw6653 we melt recycled post consumer glass that is mostly* soda lime glass. The furnaces (where the glass is melted) run between 2100-2400 F. The annealers (where they cool to room temp) are around 1100 F. I've been describing roasters as a bean annealer :)

[@devonlewis5081]

excellent videos, kyle. really clean look also. i just welded up a fairly straight 10x10 solid drum w vanes. can i use these same electronics for a more "manual" roaster? i mean can i go computer cord-outlet-then to the parts you used, main power switch-power supply-power button-speed controller-drum motor? same for the blower motor, too i guess? then mine will be manual lpg burner and just thermocouplers w a battery powered temp guage. does any of this make sense/work?

[@kylegreenhaw6653]

I don’t fully understand what you’re trying to say. If you use all the components I did, then yes, it should work. You can choose any components you like as long as they do the job. I used DC motors and fans because the speed controllers were cheaper and easier to source. Power comes in from the wall as AC and goes into a power supply to be converted into DC. From there, you just need to wire in your switches, motors, speed controls, etc. probably a good idea to run a fuse box as well. Good luck with your roaster! Thanks for watching!

[@devonlewis5081]

@@kylegreenhaw6653 that was exactly what i was asking, thank you! i'm impressed you are still responding to people on here, thank you. i am thinking of putting together pretty much what you have minus the heat sinks, pid, usb and heating element. how necessary is a fuse box? i like to live on the edge. are you on instagram or any coffee forums? i am uploading pictures soon

[@chrischardy]

Hey man! This is freaking awesome! Great work! I've gone through the videos a few times and I don't think I've caught what you used for the drum. Do you have the details on what you used, and how you think it's turned out so far? Thanks!

[@kylegreenhaw6653]

I took a sheet of perforated stainless steel and ran it through a slip roll, then welded the seam. Then I capped off the back and made a spoke for the front. So far the roaster works pretty good, it’s just a bit under powered. It easily does a half pound batch, but anything more and it extends the roast time more than I’d like.

[@chrischardy]

@@kylegreenhaw6653 Thats awesome! I've been considering doing something similar but for roasting in a backyard grill. Good to hear that it's been treating you well so far.Great work dude!

[@michaelwilson5620]

@kylegreenhaw6653 Love the build here man. I had a vision in my head and stumbled across your video series. A lot of similarities.. I have been leaning more toward gas powered ceramic heaters though. In your above comment you felt it was a bit underpowered for batches over a half pound… I assume you’re speaking to heat source power? Have you seen any formulas or baselines used in roasters like so many watts for so many ounces of beans. Have you found your drum motor and exhaust motor to be sufficient?? Thanks in advance if you’re still reading these posts.

[@nomnommonsterr]

Would have been nice to see a video all the electronics and sensors used in this.

[@kylegreenhaw6653]

The relay is just a switch. The heating elements are powered by 120v ac from the wall.

[@dvineyard007]

Hi Kyle, Thank you for your previous response. Question: Is there any way you could draw up a simple wiring diagram for the control box?

[@kylegreenhaw6653]

The circuit itself isn’t too complicated, but I’m not sure I could make a simple wiring diagram. I never had one to begin with. I’d recommend learning how to wire individual components and once you have that understanding it should be pretty easy to build the system. There’s probably a ton of videos on stuff like that. Thanks!

[@dvineyard007]

@@kylegreenhaw6653 Thanks, I actually do have all the wiring connections figured out, it was not much to figure out. Except the USB connection, I am guessing there is a phiddget module not listed in the list of components you have in the description of each video. Nice work by the way, I enjoyed watching your build. I do think if you are interested you could create some detailled drawings of each part and a wiring diagram and it would sell with ease. Who knows maybe it would finance your next build. Take care.

[@valentinlopez47]

That’s impressive 🤩 Great job! After trying it do you feel like the roast is good quality? I mean, can you get the same quality of coffee that you would get with a “profesional” roaster machine?

[@kylegreenhaw6653]

Thank you! I’ve been able to get some pretty good results. I’m sure a pro could do better with a nicer machine, but overall I’m pretty impressed with the roast quality. I’m still playing around with profiles and such.

[@himes1821]

Hey Kyle! Nice work on the project! I'm planning on building a much smaller version of this, kinda bodged together. However, I'm using very similar components. In fact I'm pretty sure I'm using the same components just a lot cheaper from AliExpress (except the motor, and a few other things that I found laying around). Which is nice because in the future if I want to upgrade to a bigger roaster like your's I could fairly simply transfer the components. I just had a question regarding the wiring that I hope that you could answer. What gauge wire was used throughout? Was it a mix of gauges? 16 awg? 18 awg? I've looked around online and I haven't really had a specific answer. Thanks!

[@kylegreenhaw6653]

Hi, thanks for the comment! The size of your wire is going to be determined by how much power your components draw. There are charts online that show what size wire you need to use based on the current draw, voltage and the length of the wire.

what do you have to catch the chaff and keep it from building up on the heating element

[@kylegreenhaw6653]

Some chaff does land on the heating elements, it’s somewhat of a design flaw. The exhaust fan helps pick some of it up, but i do have to clean it out occasionally. I haven’t had any issues with fires or anything. When I check inside there’s usually just a little bit of ash sitting on the lower element.
