Dude, you just keep on giving! Thanks so much for this, been looking for advice for a few weeks to upscale and you deliver. Keep on spreading the spores!
Thanks a lot again for the videos! Extremely helpful in getting my own mushroom farm going as you show you can really just make most of the equipment you need.
for the downforce problem, you could use a tension strap / securing strap or how they are called. put the straps around your container and secure the straps with one of those ratchets. you can get more than a ton of downforce, depending on your strap, that should be enough to keep that lid nice and tight down
Could also still just utilizing the Velcro probably get more down force by having Velcro attached to lid and pull the Velcro Down as hard as u can and sticking the Velcro so be able to get little more pressure on the compared to pushing down with one hand as hard as u can while using ur other to pull the Velcro over and stick it.
very nice. I love the videos, Details, no "UM"s or "UUHH". no stupid chatter. Just the details clear and concise. WOnderful. Did you have on your safety crocs? I am curious if you considered just adding another (or 2) heating elemets to your boiler.
Hey you are so awesome bro I’m starting my own mushroom farm in my room in Florida im the US and I have to innovate like crazy so far love your videos you honestly inspired me to do what I’m doing now
Only yet another option... Prefitted cabinet (spring loaded) catch n latches strategically placed around your stainless box. Then with that done right, you could possibly resolve the sealing down issue with your lid.
@@OakandSpore I wonder if a return back to the generator might be beneficial. If the system were perfectly sealed, the increased air pressure from simple PV=nRdT would be problematic to say the least. You have enough leakage that you are forcing me he cool air out as you drive steam in, but as I am sure you have sussed, eventually your steam generator must produce sufficient steam to replace the volumetric and radiant leakage. Have you given thought to submerging your blocks in a cage instead? You would have the added step of draining off the water into a holding tank, but your steam volume loss could be far less. Yes, the blocks are buoyant, thus a cage. You have the experience, just trying to think how the next generation might be improved. Ultimately, you want to only provide heat to the thermal rather than thermal and steam volumetric losses. /shrug
a pressure release valve might do the trick diffrent psi avaiable used on central heating systems .The pressure cookers are usuually about 15 psi but thats a lot.Congrats to you and your wife.
Wife-heater instead of the wife-beater. Or maybe the baked widow? I can only come up with wife puns... To get more serious: How did you come to the decision to (super-)pasteurize your substrate at 95 °C? Most often I could find either pasteurization at 80 °C or kill everything at 121 °C. Does the PID controler controlls, that the boiler is constantly near the boiling point and thus pumps steam constantly? Or do you hock up the PID controler to the steam tank, so that it remains a certain temp (95 °C)? Thanks in advance!
Haha, maybe I should call it my mistresses? I don't believe what I am doing is pasturisation, or even the fabled 'super pasturisation', I believe it's an incomplete sterilization. Cooking substrate for 24 hours at 95c reduces live organism numbers down to 0.1% of what they are before you start, and I think this gives the mycelium enough time to get a foot hold. I'll make a video about my reasoning shortly..
Further on this, you don't need to use 121, you can use other temperatures, it just makes the time required longer or shorter. It's called thermal death time.
Your videos are awesome. Some bungee cords wrapped leg to leg mite solve your hold down issues. I’m trying to start a personal consumption farm at my house in New Orleans. Fun for me and Science and gardening for the kids. Hope that arm injury is healing nicely.
hey man, your vids are cool! I was wondering if you might be able to answer a question for me. For growing at home everyone seems to suggest a pressure cooker for sterilising the grain spawn whereas your using steam. I was just wondering if you had any idea why people are saying to use a PC over this method? I live in France and you can pick up a decent sized steam steriliser second hand dead cheap (all the old French folk have one for canning). I only have a tiny PC and can only get jam jar sized jars of grain in it! Thanks.
a PC does use steam. All a PC allowes you to do is heat the steam past 100c degrees. If you can heat the steam past 100c, you can sterilise much faster.
Mate I see you’re experimenting with bottles.. where did you get them from and have you had much success? Do they have a filter of some sort in the lid? Super interested on your take on them as they would greatly reduce the plastic waste
I'd name it according to its dimensions, however I would just tack on the word beast for theatrics. I'd also change the holes on the bottom for more even heating. The steam essentially has to escape through 2 containers. The second being that false floor. If you want to heat the middle differently, yet pack in more bags, why not create steam channels vertically? If not, perhaps create more spaces in the bottom grate. I imagine the Roman's knew a thing or two about steam baths. The Beast will be steam hungry either way!
Hi Tom, I have seen a lot of videos about steam sterilizers. The only thing i still dont understand is, how to vent the steam out of your tank so the pressure is not building up? Thanks
Don't bother venting it. Stream at atmospheric temperature is lighter than air and will escape too if you do this. You actually need to vent the air from below which sounds counterintuitive but it's true... With a surface area this large it would take ton metric tons of weights just to allow half a kilo of steam pressure so there is zero chance of bursting this stream tank that way.
Hey man, I thought you could use a solution for the lid. It's probably not a good idea for your back to lift this thing off regularuly and will most likely deform and rub off your seal. You have some sturdy beams right above your chamber, so how about installing a winch? Tuck some loops around every corner so you can lift the lid directly up and hold it up there right below the beams while you work around the chamber.
@@OakandSpore did you consider a construction with flipping the whole box 90 degrees and put it up a bit to be able to offload it horizontally instead of reaching down in the bottom? Some rework with your piping needed to regig the steam to still come from underneath? I’m looking at alternatives of either buying a similar sized autoclave, or go with your type of non-pressurized
@@voccyvoc better yet flip the whole box over and lower it over the bags like a turtle shell. Steam rises anyway so it makes no sense to have the door and a vent on the top
@@qwqwueis right but it's underpowered like he said. He needs to make another one which he is having fabricated somewhere. He could do it on his own very quickly.
@@cactushatmushrooms3677 ah I missed the part where he said it was underpowered. I actually just built a drum sterilizer myself, about to test it today. Do you have a parts list of one you’ve made and use successfully? Hopefully mine doesn’t have the same issue.
The steamers where the element is inside the barrel are dangerous. If there is a water supply problem, then the element will start to cook off the wood substrate. It happened to me, and turned into a giant furnace of superheated wood. That is why I separated the boiler into it's on vessel.
why not just build the box out of the insulation and get rid of the steel box? cover it all inside and out with epoxy resin and it should be strong enough and waterproof. probably less heat loss than with the steel box and a lot cheaper and easier.
@@OakandSpore as long as it is lying flat on the ground it would be plenty strong. rigid foam has high compressive strength. you can easily walk on it without crushing it, and your feet are putting down way higher pressure per square inch than the substrate would be. and coating it in epoxy resin would increase it's strength as the epoxy distributes the weight more evenly.

Great job mate. Loving the new and improved HUGE tank.
Glad you like it! It should fit around 80 blocks maxed out!
Wooow that is crazy and a whole Lotta blocks at once. I'm so happy for you. That should make your production and your life a lot easier. Lol
Hey, in my area it seems cheaper to get a broken fridge of that size, would that work too you think? cheers
Mush Zeppelin.
Looking good 👍
Looking forward to seeing the new boiler
Luv it, can't wait to see the new boiler!
Consider direct firing the stream box itself. Essentially make the tank the boiler in one.
I used to do that, but I shifted to multiple barrels on my old setup, so ran one boiler to steam them all.

Hey, do PIR insulation not toxic at 100C? If using in closed area
How did you go about creating your previous sterilizing tub? I don't think I'm ready to create something this big.

Can it be made from a top loading freezer for example? If I have one broken. Those seems to have very good isolation.

Lol, I was thinking, "Or just use a caulk gun.."
Great video! I see no pressure however; is this a sterilizer or a pasteurizer?
**Slaps the lid
“This bad boy can hold so many mushrooms in it”
So what are Temperatures You aim for inside the Substrate while being pasturerized?
Could you use an old freezer?
Maybe. The heat might cause some issues
Lol a dream to cut but a nightmare to hear get cut lol
Have you considered using the steam sauna generator? They are pretty cheap on Amazon.
Has the bottom pf your unit been padded aswell or just the sides?
The bottom as well.
If I was to build one of these would I be able to sterilise grain bags inside this?
you would want an autoclave for sterile grain.
Wondering if you could use a old deep freezer?
the heat might melt the plastic
@@OakandSpore yeah true
Hi Tom,
I have seen a lot of videos about steam sterilizers.
The only thing i still dont understand is, how to vent the steam out of your tank so the pressure is not building up?

There is a vent in the top and a pipe which lets its escape.

@@neogeo8267 so if i leave the drain/tap open at the bottom, i get rid of the condensed water and buildup pressure in the same time?
