Alex is there anyway we could chat? I am building a roaster much like the one you did and would love to hear the good and bad.

Where is the heater itself?

Awesome, good on you!

Impressive diy roaster. 👏 deseve more recognition cause you spend plenty of time and knowledge in this project

Hello, Alex, do you shore the diagram for DIY?

Will there be a video?

Arduino aficionado here, well explained and I appreciate the mode of exploration thru trial and error that any project like this offers... and how it helps develop patience! Well done. I grow my own coffee here in Costa Rica and have been toying with DIY roaster possibilities.... cheers!

I would love to try to recreate this project, would you mind sharing a electronic build list and our Arduino script?

Hi, really nice coffee roaster!. I'm trying to make my own at home. Could you please tell me the dimensions of the glass cylinder and also of the valve you used to discharge the beans? Were the beans ever stuck when discharging?. Many thanks for your answer

After having a real drum roaster the coffee does taste better compared to fluid bed roasting 😊

Amazing project! I have been meaning to do this for a while now. Was the popcorn popper powerful enough? I am currently using a popcorn popper to roast approximately 50g of beans at a time and it seems to struggle in winter. I thought about buying a cheap heat gun and using that as the heat and fan source, just hope the fan will be strong enough.

Very nice video! Thank you so much for sharing your time and knowledge!!

Awesome!!

Very nice work. I am most impressed by your approach to chaff collection. You have inspired me to attempt a propane heated version.

I want to be invited to coffee at your house! Nice work!!

What are the specs of the blower?

Great video Alex. I'd like to also built my own roaster as you have done. I don't suppose you’d post the DIY plans for that build?

Are you going to post your plans for the machine?

Good idea,to stay with roasting manually!

S'il vous plaît est qu'il y a Une machine plus grand merci pour votre travail

Wow. He said ‘actually’ like 2000 times 😂. ‘Essentially’ was up there, too. All joking aside, nice roaster.

Alex, this is exceptionally well made and described. I’ve been mulling over options and this is exactly the inspiration I needed to get my show on the road. Thanks for tackling this project and documenting your challenges 🤙🏽 Big ups from Australia

Hello Alex, I might be late to the party but I gotta say this seems very impressive! I am curious about a couple of elements on your project. Hit me up if we could exchange some emails!

Hello , Can I know how to connect from thermocouple with arduino to collect data to computer?

This is brilliant. Thanks for posting.

Very cool project! Congratulation. Your roaster is a closed system. Can you smell you roasting in the room?

What size of pipe on your chaff collection is it 4" for main body and 2" outlet for air? Did you add any fins for the vortex?

Amazing!

Are you taking orders to get one done? I would love to order one.

"easy to find" I wish....

Have you considered adding a tvoc sensor near the exhaust? I was watching a facinating video that talked about the corrilation between first crack and dramatic spike in tvoc when fan is constant as a great indicator. Could be a great data point to help in measuring given the air noise

where can i find the arduino control code. can you share?🙏

How did you hook up the heating element? Mine burns out after a minute or two?

Very impressive. Well done. I'd love to build something like this. Would you consider packaging the plans for sale?

Fantastic design / build and the presentation was outstanding as well.

I've been holding my breath since this came out, waiting for the rest of the videos.

What about spritzing some water on the beans to stretch out the roast time?

Hi Alex, Great work. You inspired me to build my own roaster and I am curious to know the brand, model and source of your air pump. Thank you in advance for your help.

Alex - Do you have a detailed parts and instruction list that you can share? Also, have you sold your roasters at all? Really great design!

Great job!!

Hi Alex! Amazing project! I am looking to build a 250-500g fluid bed and I think this design of your would be great. Do you have a contact that I can contact to ask you some questions?:D

What happened with modifications plan? Also, don't be confused with roasting time, even below 3 minutes is ok with hot air convection roasters. We have good regional roaster who uses 300-800rg roasters for all their coffee and time is below 4 minutes usually. Time you have always referenced comes from big traditional roaster and it is because they are very energy limited.

would you be able to show us the design of the heating elements in a separate video?

Yeah you could probably sell this for 3,000+

Burping makes the roast uneven, instead of making many small holes, make one bigger on the side (i use 1" for 1kg load), you will see huge improvement.

Making one now. Are you happy with one heating element for 500g? If so, whats the wattage are your plastic welding element? Thanks!
