solid build!

Good evening, Viliam. May I ask what type of blower or fan you are currently using? I am interested in building a compact chilling tower to reduce water spent chilling wort for beer production, and I think this style might be useful for this task.
Was used ceramic heating body from Heatgun . The original winding was removed. Then a new coil was made from a stronger Kanthal wire of 0.7mm diameter. up.picr.de/34622317sc.jpg

yup! I have 220 or 240 in my kitchen thats plugged into my commercial espresso machines for testing but i dont use it except occasionally , i rebuilt my kitchen with 110 induction elements... its a 60 year old condo ( built before i was born lol)
Nice work Viliam. Where can one find information how to program Artisan to reduce fan output throughout the roast cycle? Is special hardware needed? I'm learning Arduino & TC4 and am new to the Artisan program. Thanks.

If this isn’t in production 6 years later then do it now. I have never seen such fluid action like this before. Great job
It is seen to be very efficient and if the noise from the air injector could be reduced it would be great.
very good video Greetings from Chile
Great progress, beautifully documented. Good work!
Hi Frans, are you interested in multi-colored beans?

When it is written heater 4kw, so...?
Beautiful! Just shared a link to this video in the Fluid Bed Coffee Roasters group on Facebook. We'd love you to join us!
i wish i could see the graph clearly.... Good work !!!
This looks awesome! Im working on my own at the moment
If you have any questions, the address is at the end of the video.
How do you measure been temperature? Is this even possible with fluidized beds?
It looks like you are controlling blower speed. What are you measuring & how in order to set the alarm to slow the fan?

Hi daniel,
I use different chamber sizes, always for a certain dose size.

Are you variable controlling your heating element. If so what are you using?
Could you tell us about the bean dump?
Where i can find this metal pipe that you are using at the end to get beans out?
where can I get one of those cylinders?? i've been looking like crazy
at what time is the 1rst crack? can't hear it...

The 700w vacuum cleaner engine is on the left side of the picture.
Super nice
Hey, awesome roaster! What kind of heating element do you use?
Was used ceramic heating body from Heatgun .
The original winding was removed. Then a new coil was made from a stronger Kanthal wire of 0.7mm diameter.

I am very impressed 👍 is that stainless steel or aluminum housing?
The funnel is made of plain steel.
The other parts are made of stainless steel.
Womdering where you got your glass tube?
In one company from the Czech Republic, also with cutting and grinding the ends. Now I have a few 130mm tubes ready.
Looks great! Is it possible to provide a component list for the rig?
This is too general a question.
If you want something specific, write to an email.
do you have a link for how the rig was set up?
@@viliamselc9074 do you have any detail on what blower you are using, cant see it it any of video's
Is the motor ac? If so what have you used to control it via arduino?
Yes. TC4 shield, zero cross detector, random fire SSR.
@@viliamselc9074 do you have problem with heating? i had to build cooling tray, as the air was getting 50c
What are you using to control the vacuum motor speed hardware wise?
arduino + tc4 shield, aArtisanQ_PID, forum.homeroasters.org/forum/viewthread.php?thread_id=3322&rowstart=120#post_59700
@@viliamselc9074 So, Phase-fired control with an SSR, got it.
Thanks for the info and fast reply! :)
What delta settings do you have? (seconds and smoothing)
I don't think I changed anything, I left 6s / 8
Any updates? I’ve built my own off of this design. Been roasting with for almost a year now.
Can you share your design? I'm hoping to build one as well

@@viliamselc9074 Thank you Viliam. I'll check those references. Happy roasting!
Buenos días. Donde puedo comprar este equipo
It's easier than buying it to build it yourself.
I never saw first crack
Why is this called a fluid bed roaster? Fluid refers to a liquid, didn't see any.
"having particles that easily move and change their relative position without a separation of the mass and that easily yield to pressure : capable of flowing
"
Thank you for the explanation.
I'm building one by myself too. Would like to talk to you, Can you share your email?

I want to try on building Fluid Bed Roasting Machine, can you help me build it? Maybe send me your email?
