Induction capable pressure cooker

[kb0nes]

So I have an odd little science project I am scheming up where I have a need for a pressure cooker that will work happily on an induction cooktop. I am looking for something in the 16-20 quart size range where most seem to be aluminum pots.

I have a suitable 20 quart stainless bottomed stock pot, but I would prefer something where the lid is sealed and physically affixed to the pot.

I may be able to employ a Presto aluminum pressure canner by immersing a 416 stainless plate inside the bottom of the pot to do the magnetic/thermal conversion.

Anyone have any leads, suggestions on largish induction capable pressure cookers's? Bonus if it isn't a high end $$ unit for when I start to cut holes in it :^)

You are chasing the Holy Grail. I hate to sound simple, but have you Googled "16 qt induction pressure cooker"? I have a 12 qt Kuhn Rikon so that's close to what you want.

Hey Tom, yes I did Google a bit and didn't come up with anything overly promising. The Matfer models looked best but appeared to be ~$250 for anything near the size. I like how clear the center of the lid is which is a part I would be modifying.

I was hoping for the miracle of someone having dragged a suitable unit out of a thrift store that was surplus to their needs!

I may end up with plan B, using a Presto with a stainless plate in the bottom. The other rub with the aluminum models is that I can't simply weld stainless spuds to them, so that would be another hoop to clear.

Speaking of Thrift Stores, there were WWII era pressure cookers to can all of that Victory Garden produce that had a body of blue speckled porcelainized steel and a lock on lid of aluminum like a regular canner; the idea being to save aluminum. Unfortunately, the bottom was sort of recessed so it might not make enough contact with the induction unit to be effective.

Would this achieve what you are looking for?

In the thread about the Panasonic induction oven a couple of guys have posted flat plates that fit over induction plates to allow regular cookware (and even glass apparently) to be used, although I expect as noted that you loose the controllability aspect - replies 4 & 11. This would allow you to use any pressure cooker

. Okay it probably doesn't make toast but that looks to be about the size of this thing. http://www.prnewswire.com/news-releases/panasonic-unveils-worlds-first-countertop-induction-oven-at-international-home--housewares-show-300231299.html

Al,

I did catch that plate on the other thread! Indeed it would work, but then one really ends up with no better efficiency or control then a resistance electric element.

I would consider something similar, but I would use a machined plate of stainless inside the pressure cooker. By being immersed into the fluid being heated efficiency and response would be induction like! I don't believe that the aluminum pan will effect things other then adding a little spacing which may loosen the magnetic coupling.

Seems like a lot to go thru to heat a pressure cooker.

Robot or human?

Seems like a lot to go thru...

First off it isn't a pressure cooker. The reason I want induction is for the control/response and that I already own a 1.8kw Volrath induction unit. And even that may not give me enough output, but it would well out perform a 900w hot plate!

If I were to do anything other then induction I'd go to a direct immersion resistance element, but then I have to build a controller.

I hope  it works out for you.   I guess I did not understand the OP.  A

Inquiring minds want to know. Is this "pressure cooker" going to be used for making meals, or are you devising a sterilizing processor? I know the engineering minds in this group and the projects that they undertake for fun and amusement.

Usage is one of those kinda black-ops things...

Fractional distillation of fluids with dissimilar vapor pressures, hmmm

You're wanting to make an induction capable still.
