Good choice on the bean. I was able to snag ten or fifteen pounds of a Black River Estate Microlot from Yunnan. I draw it out once I start hearing first crack, and I take it to the cusp of second crack before cooling.that brings out the caramelized notes really nice for a good drip/French Press application.
Thye Coffee I can't find the exact model in my country, so I use what available. I'm interested in the lite tc4 that you build. If you could make a guide on how to, that would be very awesome
+Didi Kusuma hey there, do you have experience making pcb board? Like electronics stuff and soldering? It does require some effort to make it. You can find the schematics in the Instructables page given in the description.
the only experience i have making pcb board is when im still at 8th or 9th grade. soldering im quite familiar, i really cant read the schematic. im like, i can use musical instrument but i cant read musical notes if that make any sense, hahaha.
This setup is very impressive. What kind of temperature monitoring/temp. profile application is that? And, what kind of temperature sensors are you using? (I'm guessing thermocouples?) You deserve extra credit for that elaborate PVC pipe exhaust system ;-)
this is the coolest shit i have seen in a while.. how much did it cost you for the whole setup.. how big of a batch size can it hold? you gotta sell this setup on esty or ebay.. im sure alot of buyers would be willing.
+Uzair Hanif thanks! I didn't really calculate it but definitely nothing near a thousand. I'm planning to write up a instructable and I'll include my shopping list. The max batch size I ever tired is 1.2kg, but only possible after 2nd roast onwards. You seriously think people would buy this? Because I thought people would prefer to buy a properly factory made machine. How about try something on kickstarter? Lol
well if you have a good quality and durable product people will buy.. most important is it can be controlled for specific profiles, bigger batch sizes and end result is pretty consistent.. that should be your focus.. as for kickstarter etc, you will have to make it abit more asthetically pleasing to lure buyers in.. it would cost you abit more but you will ofcoarse charge them extra for what your putting in.
+Phillip Freeman yes I received that info after I finished the project. I am making another one which definitely won't use galvanized steel but in the mean time I still love this machine. The coffee is in a stainless steel drum and temperature is below 250, and thank God I still alive.
+Khmer ENT flavour? There are so many variables affecting the flavour, especially where the beans come from... The machine does able to control the temperature quite nicely though.
I like it. I've been a home roaster for 27yrs and love it. I was prepared to open a shop several times but financing became a problem everytime.

+John Havens Yup that sounds like Yunnan coffee beans to me. Good to hear someone actually know there is coffee from China Yunnan and like it :)
This is very creative. Am now starting to buy the materials one by one..I need one for my coffee roasting business.
You better build several if you're using it for a business.
This is so impressive!
incredible
this is so epic
Awesome man, I'm also diy my 300gr roaster, but using a butane can. I need to amp my cyclone using that big blower like yours
+Didi Kusuma you can find out which blower I'm using in my Instructables, the link is in the description.

+Ronald Schild hey thanks! I'm using K-type thermocouple and I use TC4 + Artisan as datalogger.
awesome! what you'r spec motor for build this?
Simply awesome Thye!!!
Awesome job!
great job

amazing. very innovative
Is that a galvanised bucket your using? Heating galvanised steel? Dangerous
+Phillip Freeman yes I received that info after I finished the project. I am making another one which definitely won't use galvanized steel but in the mean time I still love this machine. The coffee is in a stainless steel drum and temperature is below 250, and thank God I still alive.
@@timothycgan what did you end up using as a replacement?
I am working on my next prototype which mainly use stainless steel.
what about using aluminium bowl? is it dangerous to heat?
great stuff please teach me how to make it
+Nash sure go to my Instructables page: www.instructables.com/id/How-to-Build-a-Traditional-Drum-Coffee-Roasting-Ma/
Appreciate with your project Thye Co.
The only question I want to ask you, how is the coffee flavor that roasted with your homemade roaster ?
+Khmer ENT flavour? There are so many variables affecting the flavour, especially where the beans come from... The machine does able to control the temperature quite nicely though.
What sort of motor did you use?
awesome
Really ??? )))
Camera is zero
Way too much stuff going on, it really doesn't need to be made into this exact of a science.
It does if you want to consistently make good coffee
