DIY Coffee Roaster Build Part 1

[@mooimakervrij4483]

So rad!

[@sheanyquist]

Dude!!!!! Nice editing! Your work space is so clean. Hahahah. I need more videos NOW!

[@kylegreenhaw6653]

Thanks man! I try to keep it tidy, haha. More videos coming!

[@muhammadkiansantang3982]

Can not wait for it ✌😁

[@justinwang7815]

Nice vid, great production quality! Can’t wait to see a batch of beans get roasted

[@kylegreenhaw6653]

Thanks! I'll do a demo once its all finished.

[@Pp4Gd]

Great video!! Looking forward to the finished product and then some coffee beans!

[@kylegreenhaw6653]

Thanks! More videos on the way!

[@jhatfield805]

That’s incredible! Great to be able to see the process and share it with us!

[@kylegreenhaw6653]

Glad you enjoyed it! I'm currently working on part 2!

[@josiahcui7020]

So cool. Thanks for capturing the process! I am hoping to do a roaster re-build soon and want to vlog it too as there is not a whole lot out there, but I love watching stuff like this. Also very cool to see a build of this size and quality. I can't weld, so that's a bit limiting for my build, but this looks amazing.

[@kylegreenhaw6653]

Thanks for watching! Glad you enjoyed the video. What roaster are you rebuilding? One that you made? Learning to weld will open up so many possibilities for you and your projects. I would recommend taking a class or picking up an inexpensive machine and teaching yourself!

[@josiahcui7020]

@@kylegreenhaw6653 Yep, it definitely looks like a bit of a toy compared to fabricated metal drum setups, but you can take a look here: www.home-barista.com/home-roasting/roast-journal-royal-crown-jewel-colombia-san-pedro-t55104.html#p617740 if you're interested. Built it a couple years ago to integrate my sifter/popper setup into a neat and tidy (if unsafe, due to wood construction) package... Going to recycle a lot of its components into a hot air drum setup - for both safety and roast philosophy reasons. Because of not being able to weld (though I would definitely love to learn someday in the future), I'll still be utilizing a lot of off-the-shelf components for the roast drum, outer drum (roast chamber), outer shell, frame, trier, etc...but I'm excited as I think I can pull it off well enough to take a leap forward in roast quality (and quantity), build quality (and safety), and the 'bling factor' of having something resembling a traditional coffee roaster sitting in my garage ;-) Looking forward to your next vids!

[@kylegreenhaw6653]

I checked out your forum thread, very cool write up! I like your data driven scientific approach. I must admit that I'm more of a fabricator than a roaster, I have a ton more to learn about coffee. I've also struggled with baked roasts and flat flavor profiles, but I'm working to improve my batches each time. There's already so many changes I would make to my design since starting the project, but I suppose that's just part of the learning process. I'll be on the lookout for version 2.0 of your roaster!

[@muhammadkiansantang3982]

Nice job dude

[@kylegreenhaw6653]

Thanks!

[@takerumian1]

Thankyou

[@riograndecoffee4838]

Hey dear bro Thanks for sharing video. I hav 5kg roaster now but i bought it 4year ago. I want to build myself one roaster.

[@mmiranda39]

Nice GOAT bro!

[@kylegreenhaw6653]

Haha, poor thing has just been sitting in the garage collecting dust. Gotta take her out for a rip!

[@gatoreng07]

What did you use for the roasting cylinder/drum?

[@kylegreenhaw6653]

I ran a sheet of perforated stainless steel through a slip roll and welded it together.

[@mmiranda39]

Awesome vid on the tig welding. What cup size and welder are you using? Can't wait for Part 2

[@kylegreenhaw6653]

Thanks dude! I'm using an Alpha TIG200x. I put a Miller WP9 torch on it with a gas lens set up. The nozzle is a #7 and I'm running a 3/32" 2% lanthanated tungsten. Part 2 coming soon!

[@mmiranda39]

@@kylegreenhaw6653 Awesome! That's almost identical to my setup except I'm running a CK Worldwide Torch. I'd like to upgrade the pedal on my 200 tho

[@kylegreenhaw6653]

Upgrading the pedal makes a huge difference, one of the first mods I did. I got mine from HTP, it works great!

[@JJHawg]

Nice work, thanks for sharing. When you are welding, do you leave the gas running until the weld has cooled?

[@kylegreenhaw6653]

Yeah, I have my post flow set at 5 seconds. It will help reduce the amount of oxidation on the weld.

[@kaipyroami]

@@kylegreenhaw6653 ah ok. So that's what the pause is about. As an non-welder I was a little confused

[@drivenbypassionnetwork1276]

Nice Video Kyle! Where did you get the components to fabricate the roaster, the electrinics for the controls and rhe heating elements?

[@kylegreenhaw6653]

The raw materials and mechanical bits were mostly sourced from local suppliers and McMaster carr. I got the heating elements from Mor Infrared. The electronics came from Amazon and eBay.

[@enriquefranco4216]

Awesome work man! Im building a roasting machine now, I would like to know how much volume should the drum have in order to roast 5 kg of coffee. Thanks!

[@kylegreenhaw6653]

I wouldn’t really consider myself an expert on the subject, but my drum is designed to roast about 500g of coffee and the drum itself could probably hold 3x that. I feel like that gives the beans enough room to expand plus provide enough extra space for better convection. So yeah, maybe 2x or 3x the volume you expect to roast.

[@enriquefranco4216]

@@kylegreenhaw6653 is it posible to get your design? A description, specification, etc?

[@kylegreenhaw6653]

I don’t have anything documented. I’ve just been building as I go. Sorry, no plans available.

[@dvineyard007]

Where did you order your 3/8 D shaft and bearing plates from?

[@kylegreenhaw6653]

The shaft and bearings were purchased from McMaster Carr. I machined the blocks from a chunk of aluminum. 3/8” are not readily available. I would go with 1/2” if I was to do it again.

[@eosme]

this is awesome! what kind of welder do you use?

[@kylegreenhaw6653]

Thanks! I’m using an AHP Alphatig 200x

[@MrRandomguy4u]

Hey! Not sure if you are still active on here but how did you curve the outer shell/sheet to such a perfect radius? :)

[@kylegreenhaw6653]

I used a slip roll

[@Jdes9924]

Are you going to open source your design? THIS IS AWESOME!

[@kylegreenhaw6653]

Thanks! If I had a design, I would totally open source it. It’s really just been a build it as you go kinda thing. I’d be happy to answer any questions or help someone if they wanted to take on something like this.

[@DC27889]

Hi Kyle, Do you have the plan for the ROASTER?

[@kylegreenhaw6653]

Hi, sorry I do not have plans for the build. Thanks for watching!

[@DC27889]

@@kylegreenhaw6653 thanks Kyle. Beautifully made

[@kylegreenhaw6653]

@ Yung Chiu Thank you!

[@leandrewgonzales2287]

I wish you could send me a copy of your design for reference. I'm planning on building my own coffee roaster as well. Watching from the Philippines.

[@kylegreenhaw6653]

Sorry, but I don’t have any design documentation

[@bahtiarzulham]

Do you have any blueprint?

[@kylegreenhaw6653]

No blueprints, sorry.

[@josephpica8241]

If you don’t mind me asking, how much did you spend on materials for this?

[@kylegreenhaw6653]

I have something like $800 in parts and materials.

[@ytdrums]

Man, do you have the plan for this build?

[@kylegreenhaw6653]

No, I don’t have any build plans. I just built it as I went.

[@ytdrums]

i thought you have a plan, thats a great build! cant wait to see the final product

[@kylegreenhaw6653]

Thanks! Almost there!

[@mojaonemedia3443]

How many Kg can the machine roast at a time?

[@kylegreenhaw6653]

It can do 450g but I typically only roast 250g batches.
