yeah I know. I think its just the chamber still slowly settling to the same heat at the griddle... which can sometimes take up to 6 hours for it to reach identical heat... turn the griddle up JUST a hair, and after 3 or 4 hours the chamber has finally risen 15-20 degrees which is too much :(

I seen in that high times magazine article that we should only be going to 8 militor or something which looks to me like its the .80 on the gauge and 60 degree C at the most.

in other words. thats about 24" of vacuum (so not a full vacuum) and only 140F which is about what were doing... except with maybe too much vacuum? I think ive also seen fadedawg mention that he goes to full vacuum, then releases just a little bit of pressure so its not quite full vacuum and lets it sit like that.

We pull to 29.5" Hg and throttle the back fill valve to bleed in enough air to keep the pressure from dropping below that and boiling away the cannabinoids.

yeah I know you do, thats very interesting. so that means you dont need a 500-600$ pump then if youre bleeding off anyways and only getting 98% vacuum or whatever it turns out to be?

also... what is 8 millitorr?

8 millitorr = 0.0003149605863312 inches of hg??????? what??

The perfect pump would be one that would pull to 29.5" Hg and not care about vapors in its crank case.

A 1/6 hp lab pump so equipted sells for about $1300. We are considering pulling to -29.5" Hg with a 6 cfm pump for our vacuum oven, and then switching to the 1/6th hp lab pump, in leu of our current cold trap.

8 millitorr is -29.92968504 inches Hg gauge.

yeah a cheeto is all air...

fadedawg... how are they achieving 29.92" hg?! perfect vacuum... isnt that too much?

A perfect vacuum is 29.92" Hg, or 760,000 microns, ~760,000 militorr.

In industry, we achieved vacuum levels to a few microns using a Stokes vacuum pump with Rootes blower and oil diffusion pump after it, but you won't get anywhere close to that with a simple rotary vane vacuum pump, and the good news is that you don't have to. In fact, vacuuming below around -29.5" Hg, is counter productive in that it cold vacuums away the cannabinoids.

My next q was do you cold boil off terpenes with extreme vacuum...if the thc boils then so do the rest. Thanks for the answer!

so why is bubbleman vacuuming to 8 millitorr and producing high times quality stuff?
Click to expand...
No idea, better to ask him, but if he is pulling to 8 millitorr, it would appear that he could produce even better stuff if he didn't vacuum so low.

The monoterpenes and sesquiterpenes will boil off before the diterpene cannabinoids. All you have to do, is smell the pump oil to answer any questions as to whether you are boiling the lighter terpenes at even 29.5" Hg. Fortunately, they are concentrated enough at the point that the solvent leaves, that they still retain enough lighter terpenes to still be floral.

meltdown.. again!!!! this time I was able to recover 99.9% of it.. im getting good at these ;)


























it did look like this at one point after I whipped it up by hand, scraped it, dripped it off the blade in a big glob into a big pile:






end result :(

yup. the wax/honeycomb is all just a temporary illusion of solidified bubbles!!! any heat and it turns to goo/shatter. just for fun... ill heat it up again tonight, put it in a big glob in the center, and make it puff up nicely like that again. but eventually it just folds down onto itself and turns into oil again. with no heat.

i dont know about them either thats why i ask didnt know if you had any insight.

just watching shit grow man lol. i got a new tube, its not the one i ordered. that guy blew me off i guess, i really wanted those tubes too they where exactly what i wanted.
View attachment 2685044this is what i got, they arent 3 feet,(1-33" 2-30") and they are the size smaller tube then what i wanted, but.... i got them in less then 24 hours of asking the guy for them so kudos, and in his defensive i was describing what i wanted over the phone and i dont know tube sizes. as long as it hold a 4 or more ounces ill be happy. but i still want a half pound one:twisted:

Damn bro..that skinny ass tube looks DOPE..

I've found the smaller the diameter of the tube has a direct impact on the pressure in the tube, which seems to relate to overall yield.

Nice tube bro...haha.
