Growing Mushrooms at Home DIY Single Drum Bulk Steamer Design 

Hey now! 😆

a fairly terrifying thought

75-80 Celsius?

It doesn't matter if you need the humidity. A high pressure mister system would be much more efficient than boiling huge amounts of water.

Yes we have ours on a digital time temperature PID.

Its not humid in there, the steamers are on PID's the only time it gets humid is unloading then the bags dry quick.

@@MyersMushroomsFarms I'm glad that it's under control that's a good thing but I don't understand how being in a PID can have anything to do with it??? Pids are basically feedback loops the control temperature or humidity or whatever.I use pids from my days in the robotics industry I have a whole box of them. So I basically know what they do it how they do it. But you are steamers running in a PID would have nothing to do with how humid he gets in the general area of the steamer. Unless you mean not a lot of extra steam escapes because it's just kept in a balanced rate??? even then I don't really understand the statement I'm not trying to be an asshole I just don't understand honestly. I think I'm going to build one of these myself but base it off of temperature it is simple PID with a t type probe.

@@ClownWhisper pid set 5F below boiling means very little steam escapes

I did find em, I use stainless steel braided washer hoses now.

Only if steam contacts it.

your correct my friend, look luck :)

If ur talking about sterilizing I believe conventional wisdom is for every 1 additional psi you can lower sterilization time by 10 minutes

If you want it to last. Plastics will hold up for a bit but I hear they warp after time. Plus if you go with steel you can eventually modify to push 1-2 psi

Because of the long cooking time you can’t put enough water in. And opening to fill up would open to air and contamination ... self filling means it can safely refill on its own when needed and still remain sealed

@@perfectstranger232 What if you have a designated boiler that pumps steam into a separate barrel? How much water do you think you would need to run a 24 hour cycle?

should work fine.

it gets down to 20F here and im exchanging outside air every 6 mins.

@@MyersMushroomsFarms wow nice that's weird I was there in the winter I think I was in there February 8th and I never felt any coldness I heard it frosted in the desert but I didn't experience it and I went on some real early morning hides behind the organ mountains big mistake I was tracked by a mountain lion it came down it was about three football fields away from me I was watching it with my binoculars and it was headed towards me slowly I'm lucky to be alive

Sterilization is a time temperature formula for lethality. Lower temps just take longer. This were shooting for 200f for 4-6 hrs while an autoclave is doing 240f for 20 min.

@@MyersMushroomsFarms Awesome! Thanks a lot!

@@MyersMushroomsFarms 4-6 hours? i thought it was 20-24 depending on capacity and heating element/power supply?? you really confused me with the 4-6 hour thing. could you please elaborate on what you meant by that? i'm halfway done building my own, can't wait till its done. just finished the PID now onto the barrel. and also thank you for all your videos and knowledge you have shared with the myco community.

@@siandrusko9073 total run time is longer but core temps 4-6 hrs at 195-200f. it takes anywhere from 8-20 hrs for the cores to hit that.

I guess they're unicorn grow bags, i sometimes use them they're good, check them out on Instagram @unicorn grow bags

this is for bulk substrate, use pressure cookers for your grain spawn bags

yes bubbasbarrels is manufacturing them, check the link in the description

atmospheric steam, its all you need

absolutely not. Propane is more expensive, and dangerous.

@@MyersMushroomsFarms wow I'm surprised. That's great because alot easier to do inside as well. Thanks man

all the parts are in my kit link in the description

these are actually already repurposed - so yes as long as it's clean and in great condition and doesn't have any residual chemicals or etc on the inside

sure

@@KevinLaPage-ff6bj have you done it?

@@xstnzsound1069 I do not have this large of a setup. However if you cannot increase the temp through pressure as a pressure canner you would just increase the duration of time the spawn jars are in the barrel. Hopefully the vid creator will weigh in for you on this. Take care

yes, technically you can but i would rely on a pressure cooker for that. i can fit 10 qt jars or 6 5lb large unicorn bags in 1 $160 presto 23 quart PC. I'm in the middle of building one of these large 55 gallon sterilizers but it's for substrate bags not grain jars.

You are a chemist, not a machinist. Look it up, its a thing. I learned it from welding SS and brewing where rust is a big deal on vessels. When welders weld SS they etch it with acid. Passivation of SS look it up

@@MyersMushroomsFarms funny thing I am a machinist the chemistry is just a hobby well Machining is more of a serious hobby and a money-making thing. I'm not the master machinist per se I've just been working with metal for many many many years. I have a couple of meals I am hurting to lathe of an old Logan I'm getting a monarch pretty soon.

@@MyersMushroomsFarms will ya I didn't realize you got it red hot like I said in my original post if it was just cut on a bandsaw they probably would not ever rust unless it was heated up a lot. I work with 304 stainless continuously every single day for a little side money so I do have some experience with it. But absolutely you heat it up with a torch or a welder and it's going to rust like hell I didn't realize. Again I'm sorry I'm not trying to be a dick LOL just trying to understand

@@MyersMushroomsFarms can I ask how much you paid for your drum I'm having a hard time finding one. I would really like to do one slightly smaller perhaps 30 gallon..... While I'm sitting here writing this I'm thinking I have to stainless steel kegs in the basement I most certainly could use one of those and fashion good lid for it

@@ClownWhisper just drilling and cutting the SS with an angle grinder heats the metal red hot on the cut edge. I paid like 800 fot my 85 from bubbas barrels. having ss makes it last forever and not get rusty, stays nice and sterile inside.
