Electric Pressure Cooker with custom-temp thermostat

Does anyone know of a brand of electric pressure cooker (eg instapot) where I can enter the temperature to maintain?

It's nice that these things have options for rice, beans, soup, yogurt, etc -- but I just want the power to say "stay at 42 deg C".

Specifically I'm looking to make fermented bacteria cultures (eg yogurt, cheese), so I need to be able to set it to a low temperature. My understanding is that (as a result of some folks cooking meats on too low of settings and then poisoning themselves), the government made crock pots (slow cookers) have a minimum temperature (iirc 60 deg C), which would kill all bacteria. Well, that's not good if I'm trying to *encourage* bacteria growth.

The beneficial bacteria that I'm looking to culture grow optimally between 35 to 44 degrees (Celsius). So I'd love to be able to try a batch at 35 degrees. And then try another at 36 degrees. And at 37, 38, 39, 40, 41, 42, 43, and 44 degrees too.

Are there any of these fancy electric pressure cookers that let you just enter a number yourself for the temp it should maintain?

Poison from low temperature is about as common as from proper temperature. It depends on other factors before you start the ferment.  

I usually set my temperature low for longer fermenting time as i like that flavour better.  If concerned, try one of the pre industrial cultures like villi (i think that's the spelling)  that developed without electricity or thermostats.

My instapot has the yogurt setting which doesn't let us choose the temp (but some model do).  Never had trouble with it and fast culture yogurt.  

My friend who cares about temperature and fermenting, has a thermostat to control the crock pot.  Plug it into the wall, put probe in crock pot.  Plug crock pot into wall.  Gadget maintains the temperature by turning crockpot off and on.

He says the key is to have a simple crock pot with an off-on switch, not fancy cookers with chips.  He said the set up cost him about $10 as the crock pot was from the thrift shop and ths thermostats go on sale often.

He loves it.

For temperature specific fermenting, i use the oven with the light on (keeps it perfect for koji and yogurt.   One cold Christmas, the power went out, so hot water bottle and a lot of blankets for a haybox cooker style.

A lot of good quality dehydrator have thermostat that one can set to low temperatures.  If I do a temperature fussy ferment again, I often thought of using one of those.

An on off switch sounds simple as r ranson suggests. Another suggestion would be to look at yoghurt makers - these are designed for lower temperatures, so perhaps would be a better fit for what you intend if you don't need hotter temperatures too...



this one doesn't seem too dear and says it does temperature adjustment - I'm not sure how accurate it would be. If you really need one degree increments that might be asking a bit much for a domestic appliance.

Depends on how low you want to go...   I thought of using a seed heating mat used to start plants to make yogurt in a cooler....       It was an idea I had..

The most fancy Insta pots I do believe have this option.
