How long can unpurged oil sit before vac - Large Scale Processor

[Fat Thor]

Hey guys, first time posting but I've been reading the icmag forums since 2008.

My main questions is how long unpurged oil can sit on a slick pad or parchment before it goes in the oven? The ambient temps of the shelf where all the runs go before they go in the vac is always around 65deg and there is usually anywhere from an ounce to 40 grams on the parchment. We fit 6 runs in our vac oven(3 granite shelves/2 per) so we wait till we have 6 runs ready till we put them in the vac. Since we are running closed loop tamisium half pounders some of the unpurged runs sit around for 6+ hours before they go in the oven. And sometimes things come up and they end up sitting overnight till the next morning when i get back to work so they're going in the vac oven 12-18 hours after its been put on the parchment.

For the past 3 years we've been running the tamisiums solely for edible oil and have been running mostly garbage trim through them. It isn't till recently that we've shifted towards the higher end products because more quality trim and bud have become available for us to process. This forum has been a huuuuuge help and has saved me the headache of a lot of trial and error so for that I thank you and all our patients thank you!

Right now we are consistently trying to get shatter (big surprise) and have been having a few problems. I know I'm at a disadvantage with the tamisium because i have four older 8oz units and they all have that annoying small opening to get your product out so you are forced to scrape. Ive read a lot of people on here saying that scraping causes nucleation which makes it harder to get shatter. Does anyone have any tricks? I've tried the pour out method but the lip on the tank makes it very difficult and it ends up making a huge mess.

Did 6 runs yesterday and let them sit overnight and threw them in the vac this morning, one of the slabs completely honeycombed in 30 minutes and stayed like that, 2 of the slabs are 85% shatter and the other three are half wax/half shatter slabs.

Is letting them sit overnight a big NO NO? Is that plus the fact in scraping out of a tamisium messing me up? Does anyone have similar problems or ant tricks? Any info much appreciated!

I don't personally use a closed-loop system yet, but I'm pretty sure the biggest issue is leaving your slabs with a bunch of butane in them for too long. I always scrape every run and then smear it on an oil slick after water bath purging for a while, and I rarely get wax.
Is there a reason you wait until you have 6 slabs? Might be better to stagger them somehow, if possible. If you have some kind of vacuum chamber besides the oven then you could muffin the slabs in that before going into the oven, then just re-pressurize and open the oven when you need to add a slab. Just make sure to time each one so you know how long it's been in there and so you know when to flip.
Another issue could be temperature, as you didn't mention what temp you're using. Try and keep it between 100-110F.

I don't understand why you cannot add the concentrate to the oven as soon as its ready to be purged, why do they all need to go in at once?

The main reason I'm not throwing the runs straight into the oven as i go is because i have to man 4 extractors so there is always something to do. If i threw monitoring a vac oven into the mix, mistakes might get made...Ideally i would have another person working me to man the vac oven and assist me with runs but that isn't an option at this time.

I feel like opening the oven every 30 minutes to put another slab in isn't good practice? I've been playing with temperatures but haven't gone above 110deg.

Sitting overnight shouldn't be an issue.

What temperature are you recovering your Tamisium at?

When we were running edible oil our recovery temps were muuuuch higher so I've had to get used to waiting a little longer now that I'm down to 75ish. Should i be playing with my recovery temps? Thanks for all the reply.

Just to elaborate a little on my recovery temps. The hot bath will usually be between 70-75 and will drop to the mid 60's once i drop the cold tamisium in.

Heres a picture of the first two runs out of the extractor. I will post a picture of all 6 before they go in the vac.

 

[Fat Thor]

Here are all 6 right before they head in the back, I'm putting the newest ones on the bottoms since they are the coldest and the oldest on the top

Heads up...

If you pour it will shatter....
If you scrape it will budder....

 

[JColtrane]

^sorry bro .... not true

 

[bull619]

Scraping does not guarantee buddering and pouring doesn't guarantee shatter. Just too many other factors. I scrape but anything that isn't in the first pass I purge separately as it will often budder faster.

Are you recovering butane from your Tamisium at 75F or is that oven temperature? Are you using a recovery pump on the Tami or are you using heat and cold.

Recovering at 75deg, no recovery pump, just heat and cold.

I just purged a pyrex that had been sitting for weeks, came out beautiful blonde crumble. Although the one next to it was several shades darker.......

 

[JointOperation]

as long as u cover it .. shouldn't do shit.. I had a pyrex with 10 grams of oil in it for 2 months.. sitting in a 75 degree room.. with a cover ..while I waited for money to get my chamber.. and it came out perfect shatter...

also.. scraping or pouring makes no difference.. that's just retarded.. honestly. its all about starting material.. wat temp ur shit is extracted at.. and ontop of that.. the temps and how much vacuum you pull..

ive found how much u dry it out.. or how wet the material is.. temps of extracting... deff chill butane and put packed tubes into bags then put those all into the freezer for atleast 4-10 hours AT LEAST.. that's the least amount of time ive frozen .. and got shatter or taffy...

the last time I got wax I figured out why.. it was because I was blowing my first tube.. and left my second tube and all the butane out in the heat with me while I blew.. so when I started blowing the second tube.. it was warmer... and extracted more waxes and lipids. giving me a waxxxy product.. but.. u can take wax.. flatten it with heat and a rolling pin.. veryyyy thin layer.. and use a torch.. go over it VERY LIGHTLY a few passes.. and turn WAX into a product that looks more and feels more like a shatter / taffy then WAX..

atleast.. that's what I did with the wax I had .. used a griddle.. and got it kinda like a shatter substance.. but was REALLY CLOUDY like u could see the waxes and shit.. its called FLASH Heating I think.. it worked great for me.

and then the torch.. obv melted the waxes.. and changed them into a more see threw product..

that was my one and only wax lol. that I extracted atleast.. I find if u keep your tubes cold and butane cold.. u get shatter or sap or taffy.. it all depends on how much terpenes n how old the material is.. and how long the person allowed the plants to mature.

I just found a pyrex that was sitting for over a year, and I dabbed some, hahaha for science!


It was just as good as the purged product, and it was also still stable as well

@fat thor Is there a reason you have picked four 8oz Tamisiums vs the 1 kilo setup? I ask because I have a 1 kilo set up and am wondering if I should have picked a smaller unit.

We bought our four Tamisiums over 3 years ago when there weren't many options and definitely plan on buying a 5-10b extractor down the road to make all our edible oils. 90% of the good trim that comes in from other dispensaries for us to process comes in strain specific batches and its rare to get more than a pound of the same strain so its nice to have the half pound units for smaller strain specific runs.

 

[JointOperation]

I was just going to say the same thing

it all depends on what u like.. if u are producing single strains.. and have tons of trim and larf. then smaller tubes or closed systems are best for single strains.. but if ur just going to take all your trim. and run it in 1 time.. then bigger is better......

I prefer smaller for single strains.. and bigger for multiples.. especially smaller tubes or systesm for nug runs.. so u can see if the strain is worth doing a nug run or not..
