am sick of pressure cooking grain bags so I finally had the courage to do this bulk sterilization that they do in China. Wrapped in double layer tarp with insulation in between.
The first batch was 2,100 pound grain bags. About 20 contaminated. They are the ones in the big trays without holes in the very bottom.

It took 10 hours to get it to 100 deg C then 8 hours after that.

Now I'm upping the stakes 3500 bags but this time I put it up on wood planks

Finally after 18 hours, it's 100ºC. Another 8 hours to go...
Does anyone know if I can lessen the 100ºC phase since it was above the 75ºC for like 9 hours?

Sparkle if you growing oysters and fast growing species the 80 deg C for 8 hours will be enough, well done for getting it to 100 deg! what insulation are you using?
