Vacuum Purge times and temp for different wax consistency

[chef oli]

I've read everything, I just want to make sure im safe at about 120 without turning to goo.

One thing to take into consideration is altitude. A lot of posters from Colorado may not realize it, but it takes less temperature with altitude to reach boiling points. I'm at 6600 feet, and water boils near 200°F, not 212°F. As a rule of thumb, any temperature used by people at sea level should be the equivalent of 10-12°F less at my house. Likewise, anything done at a mile high or up will take more heat at sea level due to the difference in atmospheric pressure. This is a consideration aside from bud strain differences.

As this is true and duly noted, our vacuum chambers are less efficient at altitude. We can only pull ~ -22hg (which will 'boil' water). When you do all the math, even though you can pull a 'boil' at altitude, it's not as effective of a vacuum at sea level. My theory is that you need a higher heat to achieve the same pressures while purging at sea level under a lower temp. ie: 110 deg at -29.9hg @ sea level = ~120 deg at -22hg @ 7000ft ? (temp range is a broad guess). Or is heat heat and over 130 deg regardless of altitude = permagoo. Where I am at 7200ft I feel 120deg is an ideal purge temp. Seems to work so far. Going to experiment w/ temps real soon and will report too. Fun stuff to think about!

Oh my god guys thank you so much this has helped me make my first batch! Should I post pics?

 

[qwizoking]

"Should I post pics?"

Is that a serious question?
Yes!

 

[chef oli]

here is a pic of what I made out of some bunk white widow trim. I'm not sure if i purged long enough or raised the temperature high enough to achieve the consistency I wanted. It doesn't spark or sizzle though and it gets me RIPPED!

 

[qwizoking]

What were you going for? (I forgot)
Lower temps if wanting shatter
Looks good for a first run if making wax

 

[chef oli]

Thanks for the feedback! I'm trying to get wax. I'm a little confused when checking temperatures though. Should I be checking the oil temperature inside the vac chamber and maintain that or should I check the griddle heat? I'm pretty sure I should be checking the oil but any feedback would waive away my confusion! Lol the best feeling is dabbing your own wax. This is a revolution for me guys. To anyone who gave feedback or input, THANK YOU!

 

[qwizoking]

I prefer a temp gun with you know a lil laser and check the actual temp of the oil..and they are a lot more accurate

Yes it is indeed, happy dabbing..don't burn it all at once like I do

 

[chef oli]

Any good tip for knowing when to pull it out of the vac? Will it be stable and not bubble?

 

[qwizoking]

Yours looks pretty good from what I can see, I mean it does look like fresh trim......not too dark, and still a bit oily..pushing crumble though..imo if you had lowered heat bout 5 degrees and pulled vac a tad longer it would be lighter and more creamy, but I like "budder" more.....its purged back right before the shatter stage, now were talking altering consistencies

 

[chef oli]

can anyone tell me if this means the temperature of my wax is 114? I think I messed up with the heat, it looks shattery.

 

[qwizoking]

Yea raise the temps a bit.get the oil to 120 or just under.....there's no real set temps to work with, each trichome with different ratios of compounds behaves differently. You just have to learn to watch it and know what the changes in temps do to your consistency and alter accordingly..best to make hash with the same strains till you get the hang of it
How much vac are you pulling

 

[chef oli]

I'm not sure on my vac pressure until I get a new gauge. I think I need a better griddle, this one I have sucks and wont get the oil above 120. Anyone use a good stable griddle? Props to qwizoking for the help

 

[JointOperation]

you know i had no clue you could boil off THC at under ambient temps under a full vacuum!!!.. i had no clue this was possible until G.Wolf told me..

 

[JointOperation]

i cant get temp readings threw my lid.. so i just found that after testing.. the water temp is 4-5 degrees hotter then the oil. i still pop the lid off and ill use my temp gun to see if im right.. but ya.. your lid might be different.

I prefer thecomb/crumble

^^^What Blu said^^^

Shatter is around 90-100F before oil starts to wax but is fully purged.

Don't go by temps on your griddle only pay attention to the oil temp itself. I've had strains wax up from between 105F-120F

Once you're oil gets up to 130F or higher you run the risk of turning the oil into perma goo. Better to very slowly and carefully raise the oil temp till it waxes.

If you purge from the start with large muffins at full strength vacuum you can get the oil to purge and wax faster than if you slowly raise your vacuum strength along the way as it purges out the solvent/moisture. Some BHO makers don't like doing full muffins and do the slower gradual method that's why I'm mentioning it.

 

[questionforyou]

Hey i noticed you said to not pay attention to the temp on my griddle. If you dont mind what kind of griddle do you use? I cant seem to find one with a low temp setting. Or am i supposed to just use the heat gun an see what the wax is at? If so how can i control the wax temp if the griddle cooks to high. I guess that would circle back to my first question about what kind of griddle you have. Thanks any other tips or help would be greatly appreciated an put to very good use.

Hey guys. What times and temps do you use when vac purging? Any info helps. Thanks. Looking for times and temps on honeycomb and shatter.

Shatter:
Very thin, 120+ temps, vac all the way,
Decard:
150+ temps, wait till 70% bubbles stop
Crumble:
Lower than 110 temps,
blast and put into a paddy no bigger than 3mm,
start purge at -15in 80 degrees
Wait 10 minutes
Release pressure
Purge to -20 90 degrees
Wait 10 minutes
Release pressure
Purge to -25 100 degrees
wait 10 minutes release pressure
Make into a paddy about 10mm
Purge all the way let it stay 100 degrees for 2 hours then let it cool down to become hard

NOTE!
Every strain is different, if its a crumble strain it will crumble. This is what I used for crumble strains, when it isn't a crumble strain, its very hard to crumble but takes time. Never go over 120 if you want to crumble.
