Awesome I sent an email to AllenB and JackH The email to JackH failed. I had screenshots of my settings.

Jack and I are enlisting help from our PHP site admin to try and solve as soon as possible. Thanks for letting us know.

Email address correct. I constantly check junk folder. I turned off, then on, the setting to receive notice.

Two Drawer filing cabinet fluid bed roaster
JavaJoshua-BoquistBean
The last time I started a new thread was when I first told myself I was going to build a fluidbed roaster. Boy has it taken me time! I have to be honest with myself- this still may not happen, but I have most of the pieces I have already conceptualized (at least the basic building blocks to go off anyways) . I have read people describe how they've compartmentalized their heat sources into a box, and I really like that idea. I think a two drawer filing cabinet is ideal for this actually, seeing as how it could easily be broken up into two parts (blower box + heat box). Wouldn't you know it? I found an old two drawer filing cabinet for $7. I plan on cutting the top open in a circular shape, and then doing a parallel cut in the first drawer with the same dimensions. This will create the tubing needed from the blower to the heat box, and then to the roasting chamber. I thought this top down approach of blower placement would be the most energy efficient. I'm not entirely certain how the heat box will look, but I plan on lining the interior with cement board.
Even if this roaster might be too big for what I have in mind now (and to be clear, what I have in mind is very hazy as far as electrical output and horsepower is concerned), I like the idea of having a roaster that looks bulky. Even if it isn't a monster of a machine, I want it to look like it is. Additionally, If I actually get this to work, I can attach elements that commercial roasters have, like a cooling rack. I could easily attach a cooling tray on the side of the cabinet, or even use the second drawer for that purpose. I've thought that far, but I should figure out how to cut these holes first.

My Cabinet is 32.5 in (Length) x 14 in (width) x 21.5 in (Height)

I would like to make the hole diameter be 6 inches, and have it look like a semi decent circle (that's the part im not sure about) from the top of my cabinet to the middle drawer.


So for my first obstacle. This requires some form of welding right? I start projects really well, but have a harder time finishing them, and I think this is partly why. I venture into subject areas I do not know (i.e. engineering XD)

Any backyard builders have any advice as to how you would tackle this?

Keep in mind my interest for symmetry and proper alignment from both holes. The drawers are detachable if that helps as well.

I am not a welder/fabricator either but I think you will find that there are tons of creative workarounds for lack of access/skill for those types of skills.

An angle grinder with a cut off wheel can achieve some pretty symmetrical cutouts that work. I pieced my first fluidbed roaster together out of found/DIY parts and have successfully roasted over 150lbs without issue and with great success. Peruse the forums and get inspired!

I've learned a ton from the experts and experienced here and I think you'll discover the same. Good luck!

Thanks for this advice. I have a way forward which involves a metal grinder and a skill saw. I learned that with a metal tooth bit, sheet metal can be cut with ease and with precision!

I’m thinking ahead now. Between my blower and roaster shaft is about 18 inches of space. I still like my cement casing idea, but I’m not certain about what heating element I should use. My blower is pretty wide (6 inches in diameter) and I need a wider heating element to heat up all that air. I think one wide heating element will be cheaper than two or three elements. Additionally, that heating element has to be shorter than something like a dryer heating element. I want to keep at least three or four inches between the heating element and blower, since my blower has plastic blades that would melt if they got too hot.
Someone reccomended to me a magnetic induction coil, which I suppose could work, but I’m not certain as to the wattage I need to use and don’t want to buy overkill. From what I’ve researched, my fan puts out 3hp and I think that will put me over 350 gm but this is all just guessing. With those guessed specs, what are my options of heating elements? I’ll take recommendations, but really I just want an overview of the possibilities.
