Can I substitute carboy with pressure cooker?

I was wondering if I could make fruit wine, especially pineapple wine. I just like pineapples. Cheap, sweet and sour and fragrant. I like pineapple smell. Aloha? My bestie would imagine pineapple plantation if somebody mentioned Hawai'i.

Pineapple is a symbol of hospitality in the New England.So one can expect a pineapple to be in the dining table centrepiece.

A fermentation is best done in anaerobic condition. The yeast would convert sugar to ethanol in absence of oxygen. How ever fermenting fruit in airtight container is not a good idea. Carbon Dioxide, the byproduct of fermentation would accumulate in airtight containers and would exert much pressure for the container to contain.

So, instead of plastic carboys, I'm thinking of substituting carboys with pressure cooker. It's robust enough to contain pressure. Airtight enough to contain pressure. There's also a pressure release outlet where I can just attach plastic tubes to connect the pressure cooker to an airlock. An airlock keeps the oxygen away while releasing carbon dioxide. Hmmm...

I should have taken food industry course.

Pressure cooker comes into the equation when I were recalling the even leading to my PTSD. On that New Year Eve, I won a pressure cooker. (And the next day, I got into an accident... shit!)

Should I post a picture of my idea? A sketch maybe? Be right back

Should I elevate the airlock? Or is it unnecessary.
