I'm not reading that entire thread to figure it out. Agar, LC, PF tek, shit like that is great in an electric kitchen pressure cooker. Notice that it's simply a pressure cooker and not a canner. Electric pressure cookers are designed to cook foods with liquids, not to sterilize...even if it has a sterilize function. They're not designed to sterilize anything, so they're not all that reliable.

Think of it like this: You can sterilize grain jars in a canning pot with a trivet at atmospheric pressure, but it's super inefficient and unreliable.



Electric cookers are one step above that, and many steps below a proper pressure canner like a Presto with a jiggle weight and guage. A Presto is a step below a benchtop sterilizer/autoclave like the All-American.

There's a hierarchy. From least effective to most:

1. Atmospheric steamer: not suited for spawn jars or bags, but works great for PF tek, supplemented sawdust blocks and peat casing or anything that requires pasteurization;

2. Electric kitchen pressure cooker:
  Great for liquids, PF tek, terrible for blocks, not great for spawn jars, terrible for spawn bags;

3. A pressure canner with a weight but
without a guage: Works well for spawn jars and liquids, may work ok for blocks if large enough to fit, should work for small volume spawn bags;

4. A pressure canner with a guage: Works well for everything;

5. A benchtop sterilizer unit like the
All-American: Larger units are best suited for spawn bags and supplemented sawdust blocks;

6. All other large internal volume autoclaves: The same as #5 but at commercial scale.

What about this? I'm guessing this is the exception to what you said. It doesn't really matter to me either way I just remember thinking that it looked cool.

Thats not an electric kitchen pressure cooker, that's an electric benchtop autoclave, a world of difference, and they're pretty awesome.



You can see mine on the right.

Anyone using electric pressure cookers to make grains and if so which one?

I've been using an Instantpot for quarts of grain and agar for a decade and it works just fine.  It would never use it for bags or above about 3500 ft altitude, but other than that it will do everything you need.

I understand that the quality of the sterilization will be superior with that device. I was more so wondering if it has a timer built in

Electric cookers are not canners, see the above post.

Sterilization is sterilization. There's no higher quality sterilization. There's higher level log reductions but if you use any pressure cooker the right way you get the right results
