Will2 fluid bed roaster 120mm test7, PIP, time, TC4, Artisan

[@montanausa329]

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

[@viliamselc9074]

I am going to make a new 130mm roaster. But this 120mm has worked flawlessly for several years, there is no reason to change anything. The repeatability of roasting results is incredibly accurate.

[@dichlor.methan]

@@viliamselc9074 would be also interested in the 130 mm roaster and which components you have used...motor, heater and so on

[@CesarBridgest]

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

[@palefire]

Great progress, beautifully documented. Good work!

[@viliamselc9074]

Hi Frans, are you interested in multi-colored beans?

[@palefire]

Haha! We can start a new wave, after "light roast" we'll do "Rainbow roast" -- on Facebook I've seen a batch of 'green' beans that had some bright blue beans in them, like rat poison. It could become a trend!

[@viliamselc9074]

When it is written heater 4kw, so...?

[@darrenaddy3287]

Beautiful! Just shared a link to this video in the Fluid Bed Coffee Roasters group on Facebook. We'd love you to join us!

[@ariefhendri]

i wish i could see the graph clearly.... Good work !!!

[@TilmanBaumann]

How do you measure been temperature? Is this even possible with fluidized beds?

[@ffre4k]

Where i can find this metal pipe that you are using at the end to get beans out?

[@evanwilliams3473]

Could you tell us about the bean dump?

[@PortableTaco]

where can I get one of those cylinders?? i've been looking like crazy

[@Ideasite]

It looks like you are controlling blower speed. What are you measuring & how in order to set the alarm to slow the fan?

[@rodneywalter4856]

Are you variable controlling your heating element. If so what are you using?

[@danielfostel3883]

solid build! I have been looking into a fluid bed roaster but want to go the automation route as the generic popcorn popper leaves too many variables open. beautiful design with the funnel and glass cylinder. I will have to start looking at getting CNC prices for a funnel like this... Would you recommend downsizing a bit for roughly 250g-500g batches? or are you happy with the chamber height and width?

[@viliamselc9074]

Hi daniel, I use different chamber sizes, always for a certain dose size. up.picr.de/31455273ee.jpg

@@viliamselc9074 Those numbers get big fast! 120mm hardware starts getting pricey quick. I was originally thinking about using off the shelf components to avoid the stainless milling, if its anything like drilling stainless I'm guessing its not too fun. Still Dragon has components that are close. www.stilldragon.eu/en/sight-glasses-sight-towers/382-3-inch-sight-tower.html and www.stilldragon.eu/en/reducers/443-3-inch-to-three-quarter-inch-tri-clamp-reducer-conical.html (intake might be a bit tight at 3/4"?) Unfortunately the USA site does not have the variety of components the Euro site does... Finding a column tall enough that fits the milling might also be difficult as their glass sections are only 100mm tall and would have to ship across the pond, finally the silicon gaskets they use might be questionable at coffee roasting temps. eh, nothing can be easy.

[@danielfostel3883]

This 4" to 2" reducer has potential as well... and has a thermowell built in in possibly not a terrible location. www.stilldragon.eu/en/reducers/75-4-inch-to-2-inch-tri-clamp-reducer-conical-with-thermowell.html

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.

[@bikeadventures8385]

Womdering where you got your glass tube?

[@viliamselc9074]

In one company from the Czech Republic, also with cutting and grinding the ends. Now I have a few 130mm tubes ready.

[@indiejoy3636]

Looks great! Is it possible to provide a component list for the rig?

[@viliamselc9074]

This is too general a question. If you want something specific, write to an email.

[@redzones23]

do you have a link for how the rig was set up?

[@leighgourley8921]

@@viliamselc9074 do you have any detail on what blower you are using, cant see it it any of video's

[@Ottmar555]

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.

What delta settings do you have? (seconds and smoothing)

[@viliamselc9074]

I don't think I changed anything, I left 6s / 8

[@kjeldschouten-lebbing6260]

What are you using to control the vacuum motor speed hardware wise?

[@viliamselc9074]

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! :)

[@ffre4k]

Is the motor ac? If so what have you used to control it via arduino?

[@viliamselc9074]

Yes. TC4 shield, zero cross detector, random fire SSR.

[@ffre4k]

@@viliamselc9074 do you have problem with heating? i had to build cooling tray, as the air was getting 50c

Any updates? I’ve built my own off of this design. Been roasting with for almost a year now.

[@vex123]

Can you share your design? I'm hoping to build one as well

@@vex123 Sorry it took me so long, but I've been busy. Just published a video for you, not much to look at yet, but it'll probably always be a work in progress. kzbin.info/www/bejne/hZLKe36Caq-XpKs

[@Invisiman]

Hey, awesome roaster! What kind of heating element do you use?

[@viliamselc9074]

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

[@actualidadagropecuaria8841]

Buenos días. Donde puedo comprar este equipo

[@viliamselc9074]

It's easier than buying it to build it yourself.

[@TJsFX4]

I am very impressed 👍 is that stainless steel or aluminum housing?

[@viliamselc9074]

The funnel is made of plain steel. The other parts are made of stainless steel.

[@ck1648]

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.

[@viliamselc9074]

We create Buttons, also the Button 2 "Fan DOWN". As here (forum post): forum.homeroasters.org/forum/viewthread.php?thread_id=3322&rowstart=260#post_64456 Using Alarms we run at the desired Times Action "Event Button", Description "2".

[@dominikulman7148]

Why is this called a fluid bed roaster? Fluid refers to a liquid, didn't see any.

[@holdtheonionsplease]

"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 "

[@dominikulman7148]

Thank you for the explanation.

[@dparham]

LOVE IT! WANT IT! lol

[@viliamselc9074]

We in Europe have a simpler life because we have 240V.

[@dparham]

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)

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

I'm building one by myself too. Would like to talk to you, Can you share your email? Saksith
