Sterilising in Presto
    #26867837 - 08/07/20 08:12 AM (3 years, 6 months ago)

How long do you sterilise 3kg HWP + bran bag in Presto cooker?

I usually sterilise them in drum at atmosferic pressure, but right now I need some quick fixes.

Edit* 15psi for 2.5 hours. Thats what I do for 5lb sup blocks.

Be patient and keep it simple.

What size blocks are you doing? I wouldn't want to run a 10lb block for 2.5, more like 3 to 4 depending upon substrate.

Edit*
Sorry I was about to start driving...

For a 3 kg (6.6lb)block I'd run for 4  hours.

4lb Spawn bags 3-3.5 hours,

6lb spawn bag 4 hours,

Supplemented 5lb blocks I'd do 3-3.5 hours,

10lbs supplemented production bags I'd run a 4 hour cycle.
