lids popped off during pc cycle
    #22299788 - 09/27/15 06:15 PM (8 years, 4 months ago)

I have the plastic white lids with an sfd and ship.
Well at the end of my 90min pc at 23psi I opened it and
saw the two jars that had the large mouth lids had popped off
fortunately it was only sawdust but why did this happen?

23 psi? Why so high? That's pretty hot, the lids prolly softend up and became loose

Yeah I dunno if I'd run the plastic lids so hot... 18-20psi is probably plenty..  I have enough problem with those loosening up at the normal temps.

Ok.  Also perhaps putting tinfoil over Em may help too.

I thought 15 psi was the required temp?

23 seems really high especially for plastic.

It's the minimum required temp for a 90 minute run to be effective.  More doesn't generally hurt but obviously something crossed the boundary of too much.

Yeah not for plastic. For metal you can do up to 30+ psi :lol:

Not sure what it would be for lids. Every pp5 product has a temperature tolerance

plastic jars for some reason come under pressure when you cook them.
for me in my regular pot it leads to deforming of the lids
and the people who sell the plastic jars i use recommend to leave the jars partly open
during sterilisation to prevent this.

Plastic lids suck. They do not seal on their own. 23psi is awesome. I bet the lids didn't like the extra ten degrees.

platic lids are fine if you don't fuck it up and warp them.

Putting plastic in a high temperature environment doesn't sound like a good idea period haha.

We should start a gang, club, crew, etc. The 23ers. One needs to post a pic of their pc at 23psi or above to join. We could have meetings and shit. We could laugh at the 15ers. It will be great.
