AA 75x Sterilizer
    #21297398 - 02/19/15 08:02 AM (9 years, 2 months ago)

Alright who it is that runs an AA 75x sterilizer? I remember someone saying they had one but it took a chunk of their tax return, who was it?

I want to pick your brain about what you really can fit in it, how you like it, upkeep, drawbacks of it, time to temp, etc. I can't remember if it was blindingleaf, Pasty, or Muda but I know one of you mofos said you had one.

pasty does.
a 941AA will hold more substrate because the heating element does not take up space, but u need to run it on a stove/gas burner or electric hot plate.
i use a 941 for large bags.
i thought about selling it and switching to the 75x, but i re considered, and now am just looking for a good hot plate to use it with.  it will be cheaper than buying a 75x, shipping it, etc.
75x main benefit from what i understand is its less babysitting, it has its own thermostat inside.
also look into getting a toggle valve for the standard PC instead of the weight that jiggles.  will allow u to run higher PSI, and lose less steam.
there was another thread about it last night, and it kinda convinced me to get one, as I'm just using the circular weight right now.
if price isn't an issue, a 75x may be a good bet.  for me, it is situational and price issue preventing me from switching.
a FULL 941 is fucking heavy as shit

That's why I'm leaning towards an electric sterilizer. I don't wanna have a 2 person lift team everytime I try to run it, not to mention the old lady is pissed I warp the eyes on the stove with a full 23qt once the element gets red hot lol.

I doubt I have the clearance for the 941 anyways. Any idea how much space you lose with the 75 vs the 941? What do you fit in your 941 bag wise?

i put six bags in there @ 9lbs each bag, so 54 lbs of  hydrated grain in one run.

not sure about how much space is lost in 75x.  Hamloaf would be good person to ask, he uses both 941 and 75x.

i think the 75x needs a special plug???  so make sure u get that info as well, it pulls a lot of energy.

Well they have a 120v and 240v model. I'm assuming it's much quicker to run the 240v but I don't have an extra 240v outlet and don't want to mess with the electric.

Any idea how many quarts 9lbs is? I never weigh my bags just measure out quarts. Just trying to get an estimate

probably around 7 i think??


look into getting an impulse sealer for large amount of grain per bag.  i know there are zip ties in the above picture, but I'm getting better growth with an impulse sealer.  larger plenum of air above the grains for larger amount of mycelial respiration.
sometimes with smaller bags, i will still use zip ties though.  i trust impulse sealers a little more for some reason :shrug:

I've been looking at them but i always see horror stories of failed seals. Care to recommend a quality one? I've been using zipties for as long as I've been using bags but you're right, it does greatly reduce plenum space.

this one does well by me.  seals 2.2ml thick bags at just below the "6" setting.
i use .2 micron bags, so i do not seal before PC.  others seem to have luck pre sealing with 5 micron bags.

I see that same model EVERYWHERE so I figured it was one of the cheap ones that create shitty seals. I figured you would be using the foot operated model lol

I got a 120 volt 75x. You do lose some capacity with the liner but I know it is possible to run without it, you need to tie up or remove the steam line. Apparently it does help with capacity tho I have not done it myself. With the liner I do either 12 quarts jars and just recently I ran 4 bags each with 6 quarts grain.

Upkeep is pretty similar to any other AA but you want to make sure the element don't get too much scale built up if you have hard water. I keep mine on a cheap table with the legs supported with two by fours and castors on the bottom to wheel it around if I need to move it. It holds temp really good, once you find the sweet spot on the dial it will stay pretty much there. Also there is no worries about running it dry provided you have a good seal on the lid. Quiet operation is ni e too.

Its a pricey purchase but holds its value well.

Ouch. I manage to do 2 7qt bags in my 23qt. I was hoping to get a bit more mileage out of it than that. So with the 75 I would be losing capacity for 2 bags versus a 941?

That's quite a large amount if I'm not misunderstanding. I couldn't justify the purchase for 4 bags a run, maybe 6, def 8 lol.

Keep in mind I'm using the liner.  You would gain a fair amount by not using it. Many people do. I figure 6 bags for sure without the liner in. Maybe someone who does not use the liner will chime in. I use it simply because i don't really need the extra capacity. For me 24 quarts of spawn is enough to do a dozen of my mini monos or four 66 quart monos. I really don't need more than that per run.

Need is a big one. If you need more spawn than that per run then maybe the other benefits are not enough to make it worthwhile.  For me, being able to to my sterilization cycle in my basement and being able to just set the dial and come back in 2 hours is worth it. Its a big investment so I'm not gonna try and sell you on something that might not be suited to your needs.

I like the set and forget of it. How long did it take you to dial it in and how long does it take to hit temps/pressure?

Depending on how hot the water you put in determines that. Really hot tap water can get it up to temp and pressure in about 25-35 min also depending how much pressure you like to sterilize at. I always go for 20 psi. If you open hot and load again its more like15-20. Cold water can take an hour so I never use cold.

I didn't know you could open a sterilizer hot lol. How would that effect bags?

Would popping the vaccuum pop bag or super inflate them, would it sick contams in, etc

I don't mean right after the pressure drops, tho I did do that once to see what would happen. The presealed bag got huge but didn't burst. But the AA will hold heat for a long time after the pressure is at zero. Many times I will run at night and it will still be warm when I get up 8 hours later.

I have two x75's, two x25's, and a halfway modified AA 941PC.

The only way that I can get full capacity out of my AA x75's was using spawn bags filled with 8 quarts (2 gallons) of materials a piece by "cramming" 5 of those into the x75. 

Personally I am favoring the 941 PC over the steroclaves these days simply because the amount of grains that can be sterilized at once can be exceeded by 7 quarts, meaning 48 QUARTS can be fitted into the AA 941 and sterilized once.

The major reason more substrate materials can be sterilized at once in the 941 PC over the electric steroclaves is due to the absence of the heating element that the x75's contain.  Gas is more expensive than electricity though.
