It depends. If you look at my set up I have a Locking Extension Cord for my drum and a 12 gauge dryer cord for my PC. You have to make sure you get the right gauge cord to handle the amps or you will have a fire. Remember it has to be able to handle the amps for the specific length the cord is.

I use this as a false bottom it is expensive but awesome...

well I do have to admit I have tried it on 14 and or 16 wire once or twice in a pinch with no issues over the years. I could feel a slight warmth but that was it. Though I recommend not to do that.  Now my 12 gauge only gets warm where it is sitting right up near the steamer putting off all that heat so I can keep the connection out of the rain. And so is everything else right there warm. But if I don't have it near there it doesn't get warm.

Oh that looks like a nice false bottom. Though that will steam off more water than Those 2 bricks have 2 others below it on end lengthwise with the element going inbetween.

and as for wire sizes I was mentioning https://inspectapedia.com/electric/Electrical_Outlet_Wire_Size.php#:~:text=For%20a%2015%2DAmp%20circuit,copper%2Dclad%20aluminum%20wire).




I must say I don't understand the thinking behind the false bottom. With a solid false bottom, you are just forcing the steam up the sides and making it take longer to heat up the center bags. You are just heating up the solid false bottom instead of the bags. The more steam you get into the drum the faster the bags will heat up. So it takes less time to do the same process.

You are just heating up the solid false bottom instead of the bags. The more steam you get into the drum the faster the bags will heat up. So it takes less time to do the same process.




I thought about that too when I first put all the bags together. But for the center bags there is space between them too. 8 bags per row, 6 around the outside and 2 on the inside. And there is water on the solid false bottom either from when I fill the steamer and just don't lift the lid to make it go off or because I fill just slightly over the false bottom so maybe a centimeter of water on the bottom. So there is water to steam up in the center to not slow things down like we both had thought about. And then once the Steamer is up the temperature then it won't matter anyways once that water steams off the false bottom.. but it doesn't really because of the steaming airflow cycle inside, water will steam up to the lid then drop down towards the center and side because I try and restrict water from steaming off without building up any pressure.

I want to run my steel drum on a little pressure, maybe at 2-3 PSI, no more. Can someone help me find pressure valve and "rocker"?

Running at 2 to 3 psi is a waste of time. It does absolutely nothing but cost more money to build. There is a reason no one tries to pressurize their steamers. It is because it makes no difference in the time needed to steam your bags.



By the chart, you raise the temp by 9 degrees. But if you really want to do it here is what I bought. A rocker is not needed...

https://www.amazon.com/Presto-Steam-Gauge-Pressure-Canner/dp/B001E296AS/ref=sr_1_1?dchild=1&keywords=presto+pressure+gauge&qid=1594135308&s=industrial&sr=1-1-catcorr

https://www.amazon.com/85407-Pressure-Cooker-Interlock-Presto/dp/B00KB8DZVC/ref=sr_1_3?dchild=1&keywords=presto+pressure+Presto+Interlock+Assembly&qid=1594135520&s=industrial&sr=8-3

https://www.amazon.com/Control-Devices-Pressure-Relief-Adjustable/dp/B007GDY3CU/ref=sr_1_2?dchild=1&keywords=adjustable+pressure+release+valve&qid=1594135649&sr=8-2

You do need the interlock. Because your lid will be sucked down when cooling if you don't have it. Then you will have to buy another lid for your drum.

You could use a rocker if you want to it would do the same thing as the interlock. But you only need one or the other...

And there was a discussion years back on shroomery on putting a steel drum under even that much pressure is dangerous. I don't remember all the math but what it comes out to is all that surface area of the drum adds pounds to everything of pressure or something so that even though it is only 2-3 psi, if it blows it blows with added force because of the big area. There was a thread or two of this talk with an engineer or two weighing in so you might want to do a little more research. Sorry I couldn't be more help on the details but it was a while ago.

I remember reading something like that. But the main thing I remember is even under the 3 psi pressure it did nothing to help. 9 degrees really!! I can run mine under a small amount of pressure if I want to. It is already set up to do it. But it does nothing so all I did was waste time and money setting it up like that.

Sterilisation is time * pressure.
It's logical that more pressure means shorter sterilisation time.

I will anyway sterilising 12 hours when the temperature reaches 98-100°C, but I will be more calm with added little pressure / higher temperature. And I know 2-3 PSI is not gonna hurt the drum.

Oh, I ordered PID and K-probe... Do I need to stick that probe into one bag at the top of the drum? To read core temperature.

Again you are only adding 9 degrees farenheit doing 3 psi. Check the chart I posted. But if you want to add some psi go for it. I ran my drum at 3 psi for about a year until I found it did not help. My drum was never damaged. Well once it sucked the lid down when cooling when I did not use the interlock.

Put the probe in the top bag and watch it when it hits 200F add the time you are going to steam for and that is how long you steam for every time but you have the probe coming through the side of the drum as high as possible and still be able to put the lid on.

You do not put the probe in the bag every time.

So 93-94°C? For how long, 12h?

I do mine for 11 hours plus my heat up time which is about 45 minutes. So the total time for me is about 12 hours. But to be safe you can run it for 12 hours once the top bag reaches 200F. When I was running a 1650 watt element my total time was 18 hours because it took 6 hours to heat up. The 1650 watt element was a money pit. Now when I miss the 1650 watt element. I just flush a few dollars down my toilet and that solves the problem.

You're really treasure of knowledge, thank you for helping me and others.

I have 4500 W element. Now waiting for PID and I hope it's simple to use and install/program.

Ok, good choice it makes things easier for you to have the kit. did you get the 25 or 40 SSR? Both will work but I hope you got the 40DA it is more heavy-duty and it cost the same.

Are you going to use a low water cut off or a timer? Will you use an automatic water fill? Will you be using a fan to cool the SSR? These are questions you need to answer.

Here is a diagram I drew up for my tek to wire everything properly. I would suggest you wire it like this. Many people I have helped thought they knew better and they keep blowing up timers. So wire it like in this  and you will not have a problem...

Yea, I ordered the bigger one. I will mount small cooling fan on heatsink, I saw that somewhere.

Automatic fill, yes. With steel float valve in the drum. What's "low water cut off"?

What is "outlet" on picture?

The low water cut off will shut off the element if the water gets too low and stop you from burning up your element.

The outlet is where the cord for the element plugs in. You can also Wire it directly to the element. The way I have the low water shut off wired it uses low voltage.
