loss of field capacity in manure
    #19324460 - 12/25/13 05:21 AM (10 years, 1 month ago)

its bad to release humidity in your pc by taking the stopper off or cooling it down faster than gradually. the humidity is pulled from the jars through the temp diff right? well what about the foil over the lids, and same question for steam sterilizing the manure in jars? i thought it would be a good idea to put the pc or jars outside after to cool them faster(in like 30ish degrees F) but after reading about temp differentials and humidity leaching, this seems like a bad idea right?

Yes that is bad, never do that.

Just wait the 30 minutes it takes for the pressure to drop naturally.

I've taken the pressure out prematurely before without noticing a loss of moisture, so have others that have posted about their experiences.  I'm not saying it doesn't happen but to me the effect I would say is not dramatic.  I would very much like to know in how much moisture is lost by doing a sort of GLC style transfer of fluids to see how many ccs of moisture are taken out by releasing pressure early.  I might have to test that one of these days.

It may even be possible to not dry the grains out on the outside (the RR way) then release pressure purposely to get rid of excess moisture.

Helping it depressurize faster is a great way to crack/explode your jars.

Only if the jars have no GE though right?  I pretty much only work with jars that have SFDs on them, or a whatman filter.

yeah I wasn't really clear I meant that does the foil over the lid help prevent humidity loss?

Rapid release of pressure = rapid, flash boiling of the super heated water inside the pc. Temp swings wildly. Pop, crack, goes the jars, a big mess, and just maybe a pressure relief valve or worse. Unwise!

Yes, it will prevent some loss. As the mass cools it will suck moisture back into it from inside the pc. Can't rush that, unless you're shaking grains.

Peace,

Humidity loss is not the problem-Rapid cooling is.  You can rapid heat glass, but rapid cooling cracks it.  If you dump the pressure, it has no choice but to puke the moisture out of your jars, which causes evaporative cooling, leading to broken jars and/or ruined filters.

It's going to take three weeks or more to get your product.  You gain nothing by 'saving' half an hour from releasing pressure.
