Steam Sterilization times related to pressure
    #26635885 - 04/29/20 02:54 AM (4 years, 8 months ago)

Due to budget and regulatory limitation I’m unable to provide stable 15PSI for longer time.

I came across this formula F0=dt x 10^((T-121)/10). Unfortunately math seems odd with this one. Example provided of 115C gives result of 0.2511 instead of 0.3981 as stated by Ankur. The second result is true for 117C. But then again, this concludes that higher temperatures need longer time…

After a little bit of fiddling I realized there was a typo and the equation should be as follows: F0=dt / 10^((T-121)/10) ?

Am I correct then thinking that if I'd get stable 80 kpa (11.6 PSI) resulting in 117C, all that would be needed for proper sterilization is to PC it 2.5x longer?

I used one of those smaller PCs in the past and usually sterilized grain for 2.5-3h.

Arent 2.5-3h range normal for regular 15PSI? At least for bags as i'm going to roll with them instead of jars.

Yeah, for bags you want to go longer.
