55 GAL SINGLE DRUM MUSHROOM STERILIZER BUILD DIY

[@samkshoemaker]

When mushrooms get huge in the next ten years a lot of young mycologists are going to owe you a major thank you for making these teks available to the public. Thanks for all your videos.

[@ryandixon1102]

They wont be, this is a niche market...whether its magics and illicit or gourmet and medicinal...meat will always be the primary staple and secondarily veg and fruits or maybe i should reorder that and say processed/box bullshit. But never mushrooms no matter the efficacy.

[@samkshoemaker]

​@@ryandixon1102 What data do you have to back up these claims? All forecasts show that there is tremendous market potential in fungi. In many parts of the world mushrooms are not niche but a mainstay, so why won't that happen in the US? The mushroom businesses I am working with are growing exponentially fast. Everyone and their cousin is starting an urban myco farm. Avocados, kale, and non-meat alternatives were "niche" 20 years ago, and now I can find all three of these option at most fast food restaurants. Avocados are practically worth their weight in gold. The world is moving away from our reliance on meat. Growing mushrooms is far more sustainable. Right now most grocery stores sell Agaricus bisporus only... shiitake if you are lucky. Water's warm jump in my guy. Room for everyone.

Sam Shoemaker I don’t need data when it’s observable reality and history there dumbass. Do I need data to tell you that you’re breathing air?

[@DsChelI]

Indeed. 4 years later and I’m finally in a place to try to get the ball rolling. Coming to the comments to give a huge thanks. Amazing seeing the beautiful sterilizers available now with bubba barrels. Thank you Mr. Myers!!

[@davidlanday6102]

I built one for just about $200. I am actually running it now on six test bags stacked on my false bottom floor. I opted for a steel grate welded to a custom table-like set of steel legs instead of the solid steel flat sheet. Im very happy with the results and I learned some new skills making it (tig welding specifically). Getting the level of the float just right can be tricky and if you can find a smaller stainless float I would go with that as the water level will not need to be as high, leaving more room for substrate and spawn inside the barrel. Thank you for the inspiration! Also shout out to archers mushrooms out of the UK for very detailed build instructions

[@aPlusGrain]

Is there a link to the false bottom stand? The stainless steel the rack sits on?

[@TheSkyHive]

Nice work man!

[@Laotzsa]

I’m skipping the false bottom In exchange for multiple grill grates that I mount with bolts through side wall of barrel. About to test run the puppy with no substrate and if all goes well will install my racks. The grill grates will be easily removable, just pick em up. My thought is this should help reduce run time via increased surface area of steam on bags. Anything for a more thorough sterilization and steam penetration. Stacking the bags on top of each other on 1 false bottom just seems like it goes against everything I learned about spacing the bags during sterilization. I’m thinking I should be able to get roughly 4 racks in my 55 gallon barrel. I may loose a bit of internal space but should be negligible as I will place each upper level grate essentially utop of the bags below. Maybe loosing a total of 1-2 inches of spice while ensuring no bags touch each other.

[@normanladdleschnitzel1928]

How did the test run go? any notes on the build you would care to share?

[@fargo9059]

Sir. How did u set up ur water pressure regulator? To what direction?

[@zorankospic6243]

Hi! Where the excess water vapor goes?

[@jockelization]

Found this video just when I needed to. Thanks for this upload.

[@jorgecabrera5605]

hola, so nice from you for share. i got a question: how much pressure that metal barrel can handle?... is a regular barrel?

[@e3z1]

Where do I buy one ?

[@eduardodiego3499]

Sir if I use a big steriliser box do I need to put a small hole on top to avoid pressure buildup?what if the source of my steam is a drum below and also part of the steamer box,does it produce pressure in the whole steamer if I will not place a small hole above the box?tnx

[@jgross1991]

I need to build one so bad but don’t even know where to start.

[@MyersMushroomsFarms]

You can always just buy a built one from bubbas barrels

[@jgross1991]

@@MyersMushroomsFarms can’t really justify it when you look at their prices compared to what people say they have in the ones they build.

[@noedasuaconta292]

it's a vaporization sterilizer? it works better than atm sterilizer?

[@bebopchan]

Where is the karlin (? I was using subtitles) box link? I have everything I need for the drum and it's half built. I'm no electrician though and have no idea where I need to put my Inkbird for the life of me 😂

[@fxbootstraps]

Great videos - did you know caulking contains low grade talc, which in turn is considered low grade as it contains asbestos. It warns not to apply where abrasion can take place. Just letting you know.

[@brandtrosenstock]

Which heating element are you using their

[@fargo9059]

What is that insulation?

[@brentmiller7441]

Would there be any issues using propane as the heat source?

[@TripleDDDD]

Noob question: How much steam does it produce? Is it adviced to operate it outdoors or can it be done indoors?

[@trevormahaffey3393]

How big is the primary vent hole?

[@sunnyjones682]

Some of the links expired fyi.

[@SDRsUnited]

Is it steriliser of pasteuriser? As I understood its two different things.

[@MyersMushroomsFarms]

Its a atmospheric sterilizer for bulk sawdust substrate.

[@redditRangler]

Can you sterilize grains in these as well?

[@gaiagaiagaiagaiagaia]

Hey my man. Long time watcher here. I love your videos, they're fantastic! I was hoping that you could let me know if you did anything to reinforce this barrel you have here. I have acquired a food grade steel drum and I'm waiting on a heating element and the rest of the kit, but I've been doing some reading and apparently these barrels start bulging out at 8psi. Other sources say they can handle up to 40psi. I'm nervous to try in case I get a nice explosion. If we are aiming for 15psi over a few hours, surely there has to be some reinforcement to the steel to stop it from bulging. That being said, I've seen lots of these sterilizers around and as far as i can tell, the only reinforcement would be the insulating layer. What's your take? I was thinking if reinforcement is needed, some ribs around the outside and on each end may have to be welded on, and some MIG welding around the seams to double them up. I will have to learn welding! Anyway. Any info you can provide on how these drums handle pressure would be invaluable to me. Peace and love

[@matthewholloway9507]

The lid is vented so no pressure builds up. He explains it in the video

[@gaiagaiagaiagaiagaia]

@@matthewholloway9507 ah yes i understand now. I thought that these barrels were reinforced for 15psi but i understand they are meant for steaming for several hours at atmospheric pressure now. Still ingenious. Still gonna build it :) Thank you!

[@justdaniel7995]

Put on a safety valve on lid, problem solved. But barrel drum like this, Im just curious it could be sealed perfectly as a pressure canner. 🤔 maybe he puts on a gasket and lid lock? If not, those steams gonna find their way out anyway. Anyhow.. always have a backup hole 😂 good luck

[@wolfram77]

this place looks so different, interesting i like it. where is this?

[@MyersMushroomsFarms]

it was shot in my backyard farm in el paso TX

[@TheZde]

how much energy the sterilizer you spend on a batch?

[@bartacomuskidd775]

Sorry Eric, your arm was blocking when you opened the steamer. Does the PID have a sensor drilled through the wall? Is it Pressure or Temp controlled?

[@MyersMushroomsFarms]

Its just a timer on this one but i run my newer drums off a sensor at the top that has a temperature and timer contol. Its 0 psi. You can buy these turnkey now from bubbasbarrels

[@janawynsma3861]

How do you get your heat?

[@lololollaughatlife1431]

I am interested in purchasing one.... how many 10 lb blocks can you fit inside? How hot does it need to be and for how long?

[@MyersMushroomsFarms]

you can check out bubbasbarrels for all the sizes and spec.

[@mistakin1]

How much would they be to build or buy

[@MyersMushroomsFarms]

They are available from bubbasbarrels

[@mihkeljurima1007]

How do you pasteurize your substrate though?

[@teknacious]

but bag in turn on machine use wait take bags out inoculate wait harvest

[@northfloridafungi9336]

Haha I made mine yesterday, gonna make 2 more soon

[@bartacomuskidd775]

Pretty damn cool huh? This is going to make huge difference.. I wonder if they could be slaved.. with some black pipe. Steam expands 1700 times, so it would work into them I think.

[@ClownWhisper]

It's so easy to build a feedback loop driven boiler like this it's not even funny bubba's barrels is a total rip-off I'm sorry maybe he's the greatest guy ever but he rips people off that's way too expensive for what you're getting I could literally build three of these in an afternoon

[@MyersMushroomsFarms]

You get what you pay for. Its turnkey, TIG welded, and full Stainless steel, and of course there is going to be a markup for the company to make a profit. Not everyone can fabricate like you and I so i teamed up with Bubbas and they are doing a great job of production and product support. Talk to anyone who has one and they are fully satisfied. Of course you can always build it yourself for cheaper that's why i share how to build it for those that would like to as well as offer them pre built through Bubbas. It realistically takes a worker 1 day to make one of these, machine shop labor rates go around $100+ an hour. They are build to order so basically these are custom made and not on an assembly production line where costs could drop.

[@ClownWhisper]

@@MyersMushroomsFarms I'm not trying to be an asshole I'm really not but I'm in the wrong goddamn business. I could build these at a third of the cost of what they're being sold for maybe I will. I would still make a huge profit.

[@samd1405]

@@ClownWhisper cool bragging bro

[@ClownWhisper]

@@samd1405 how on Earth is my claim that I could build it for a third of the price Greg? I mean it's not like I said I could build one of those in my sleep with my arms tied behind my back. I literally have all the components in my garage and I will build one today probably in about a half-hour other than the insulation and I didn't pay maybe $30 for everything? Actually no $30 I got for the that came with a very long thermocouple and I paid 17 for the element. I have a real heavy duty cable already for the chords I believe it's 8 or 10 gauge I can't recall if I had to buy the plug and which I already have you would add $5 onto it. Real simple feedback loop is there a rocket science in the parts are available everywhere. Go to pay $2,000 for a goddamn barrel with a PID on it no I'm sorry this gouging that is the most ridiculous thing I've ever heard. Oh shit I forgot it's $30 for the float. So what's that all together somewhere around $80?. The Damned Farrell's the only expensive thing. But again how is it bragging to say you could build one for cheaper? That doesn't make me special that just makes me honest
