I read through this thread before but now I'm actually about to do this upgrade. Was there some concern on upgrading the 921? I'm getting one used, but I think it was manufactured fairly recently.

No, I upgraded my 2012 manufactured 921 with no issues.

941.  ordered stop cock.  did not use tape or anti seize, worked perfect first try.


FINALLY, after almost a month, finished the 921 :facepalm:
first lid was old model, would not fit.  bought new lid.  when i changed my PSI gauge i somehow punctured the window and  bent the gauge, so had to order new one :facepalm:  then screwed in stop cock and STRIPPED the damn threads :facepalm:  had to use thread tap on the new lid, and order new stop cock.  when it came in, i got the anti seize grease, and that really helped, even with the stripped thread in the lid.  i think the combo of the pipe tap and anti seize was the key


i was also stoned, and accidentally put the gauge on the right for the 921:blazed:

Wait, you still managed to strip the threads on the new lid too? Seems to point to an issue with the valve threads, did you try more than one valve in those lids? Man dude, I don't know how you had so many issues with what should be an easy upgrade... At least you're up and running, even with the valve and gauge swapped! :lol: As I was reading your post I saw that pic and first thought that was your solution to the threading problem, then read you were just baked.  :getstoned:

i know man, i felt retarded from start to finish lol.
i did the 941 first, and that was really fast and easy, didn't even use a tap or grease.
when i screwed into new lid of 921, i did it what i thought was the same way, by hand at first, then wrench.  but when it would go above 5PSI, it would leak, so i knew i fucked it up :facepalm:

How does this style of control-valve vent steam? <-- Original question

Edit: I'm an idiot. I figured it was supposed to be an up and down toggle switch, lol.

My next dumb question is, if it holds a vacuum so well, am I going to have to wait 24+ hours to open it after a cycle? The manual for the non-electric sterilizers says to just pop it open but I don't want to explode anything..

It pulls a mighty vacuum, all right.  So much so that I worry about the indicator needle on the pressure gauge getting forced down against the stop-pin, rendering the read-out inaccurate.

Anyway, your concerns w/r/t exploding something inside with an uncontrolled release of the vacuum are well-founded.  I release the vacuum in multiple stages a bit at a time over a couple of hours.  Also, I leave my jar lids unscrewed a tad...but on a couple of occasions that didn't help at all.

I've put jars in (ones I made into Erbach blenders) that have no commercial filters.  The lid "sucked down" and sealed irrevocably as I released the vacuum. As more and more of the vacuum was released, it sucked down harder and harder and the glass eventually cracked.  It had the neatest appearance as I held it in my hand.  It looked like it was "boiling" at room temperature.  What it really was was atmospheric air seeping through the (as yet) unnoticed crack into the jar.  Oh well.  :shrug:

I release the vacuum in one go, just slowly. You can lift the lever a little bit to slowly let air back in. Takes about a minute or two of slowly letting air back in until it has equalized depending on your PC size.

You can avoid this if you need to by popping the valve open(slowly) right when pressure hits zero. It's hard to get it right at that exact point though because it will start to pull vacuum as soon as it hits zero. This is how I unload hot agar for pouring plates. If I'm not paying attention and it pulls a vacuum, slowly releasing it is a non issue.

Try both of these release methods with an unloaded run to see how much you need to pull up to release slowly, that way you don't accidentally pop it open too much and blow a jar the first time.

This is how slow the release should be for a 921 doing a hot agar unload that has pulled vacuum:


I have not blown a single jar, bag, or had any problems running agar at all with the stopcock conversion.

The only times I have ever blown a jar were in PC configuration cooking LC with plastic lids that were screwed down finger tight with Whatman filters.

I run my grain jar lids rubber side down and screwed on tight with SFD filter patches.

Maiden voyage!!

Ran it empty the first time. PSI kept going up up up almost to 30 (my gauge is off by 3) before I turned the heat down.

:facepalm: I didn't understand how to run it at first so I watched a tattoo guy w an AA sterilizer... when he went to open it he just flipped the switch up while the pressure was up.. and in the video the steam just shoots straight up like if you pull the weight off a PC.
I think the stop cock must sit flush on the sterilizer because mine shot steam out horizontally in every direction giving me a heart attack  :lol:

But yea, it runs awesome. So you get it up to steam, flip switch down, get it to pressure, sterilize, let it cool and then flip the back up when its cool and time to open?

If I leave the switch down and lid closed the inside stays sterile untill I open it yea?

Totally awesome Tahoe

yea, totally sterile until u open it…no more tyvek sleeves :smile:

i do it like J, and lift it slowly, ESPECIALLY FOR AGAR.  it will boil over otherwise.

Wait Im confused though... you don't lift the switch untill the pressure is down to zero right?

i just my first agar today with the new lid.  i waited like i did before, 1-1.5 hours after 0, i bring up to hood.  but instead of taking weight off, i just lifted stop cock slowly.  maybe took 1 minute to slowly release vacuum.

for bags or jars, i wait overnight or even 24+ hours.  in that case, i lift stop cock a little faster because temp difference is not there.  if its bags, i lift stop cock in front of hood if no tyvek.  for jars, anywhere is ok.

Ah right on, even when the pressure is back at zero it holds a vacuum till you lift the lever
Lift the lever in front of the hood for sterile stuff

Thanks dude makes sense now! Im t ottally digging this man it was 20 bux well spent. Especially to be able to hear my records over the PC weight :lol:

You wait over night for jars too? I always opened my PC as soon as the pressure dropped and it was cool enough unless its bags. Well if I have a second round of jars to sterilize.
Should I be leaving it overnight?

You lift the valve for a few mins during warm up to vent any air still in the pc.

I will open the valve once it's at zero of close to it if it's hot and I need to get into it. Like agar. I open it near zero, never above 5psi because it will cause the liquid to go into a full rapid boil again.

Usually run it at night while I am sleeping ava wake up to find it at -15psi. Then I will lightly open it and let it equalize. I figure anything that gets sucked in will get caught by the poly fill or bag filter

u don't have to, but u can.  i just tend to leave them overnight cause i soak in AM, drain in PM>PC, so i go to bed after PC timer is up.
i prep many jars at once, and use over next 1-2 weeks.
as a bag user, I'm sure u understand.  one jar can become 2-4 tubs pretty quick, so i end up  using bags a lot more than jars.
either way is ok though.

ikr.
i love it man.  for bags, there is nothing better. 

I'm pretty sure u an I roll the same way as far as plate>jar>bag expansion.

for curiosity's sake, i will ask, some have said that cooking agar recipes above 15 PSI cam cause unwanted caramelization.  today is first day i used this stop cock with agar.  i didn 45 minutes for two 500ml bottles.  it got up to 20 for a bit, but not long, maybe 10 minutes.  brought down, finished cycle.  poured.  wondering if any more comments on that?  i will keep it to 15 PSI if necessary, but wanted to see some pics of caracelmized media first.

I usually start my timer at 10psi on agar. I am not anal about it getting above 15psi but I try to not let it get that hot. I have not had a caramelization before. Well, I don't think I have.

I don't think caramelization is quite as big a problem as people think, I have had the sterilizer get past 25 with agar in it and it was fine. Maybe if people are doing 90 min at 15 psi that may be an issue but even then it won't contam or nothing unless you are sloppy with your technique. Might just be some slightly shittier colonization.

"i was also stoned, and accidentally put the gauge on the right for the 921:blazed:"

I saw that and realized it was a PC. A sterilizer won't work that way because of the tube. It has to go to the right to line up with the channel in the basket.

Good luck and enjoy. :rockon:
