Anybody offering a large scale SOP for spraying THC?

Thanks so much, really great ingo. This is something im geting into

Why is THC-P fragile at 70c+? What happens to it?

I am assuming the exact same thing will happen to thc-p as it does to thc when using alcl3
As a result if not al reactants are removed your presides 9 compound will isomerize to 8 and you can t flip it back

So quenching is the main problem,

So far the route looks like:

Pottasium Sulphate
Naoh 15% in DCM/ as solid
Wash with DI water
Activated carbon Scrub
Filtration
Drying

If I am not mistaking - but I surely am

That s one way to do it yes carbon scrub 2X at least is my advice

This is gonna seem dumb,

how are you dealing with the gun putting air out the front and not throwing the ground flower everywhere.

my bosses want me to make a “ground infused flower” to be sold as just that not into pre rolls. Thinking this is the best way given the situation but im not figuring out how youd get past that part.

is it just running as such low pressure its not an issue or do you hold it really far back?

Get a DAC

If prerolls is your end product you may want to consider a machine that can inject distillate directly into the prerolls with a needle at. I don’t know a machine to recommend, but my MIP want’s to upscale our cart filling process. One machine that was looked at could fill carts and also infuse prerolls. Pretty neat and you would be able to have a consistant amount of distillate in every final preroll. Obviously, if you want to sell sprayed flower too then the spray method would be needed.

I read their goal was to grind flower, add concentrate (current plan is spray), and sell sans the work of rolling joints.

So their customers might pack bowls or roll a joint sized for the occasion…or at least that is what marketing is telling sales to tell the dispensary buyers.

Imo a DAC is a better tool…but given bosses “let’s not even make joints” attitude, I’m assuming he’d prefer the lower capital investment offered by spraying.

If trying to play this in a regulated market, I believe the homogeneity delivered by a DAC may be required.

We picked up a really cheap (@thesk8nmidget) toy one that a well motivated wook could likely mix multiple kg in (20g-50g?!? at a time) over their shift.

Remote possibility that’s where the “toy” wandered off to in my whirled.

Edit. Something along the lines of this thing…

Which would be much slower than a spray gun at the kg scale, but we figured might be a useful tool to explore process development (to justify real money on something sized correctly).

No, but it does seem like you have neither tried it nor read too deeply.

yeah it was me asking after my first time messing around with it. going to spend more time on it this month and see what i can figure out. Thanks for the direction where you provide it.

Infusion machine works better and creates a better smoking experience

Xylem makes a good one and so does sorting robotics

hey I tried to spray the flower and put in drying and heating chamber oven but every time the flower gets dark! .anyone here knows the right settings for oven and step by step to get a light colour flower?

why you use heating pad?

Sry for a nooby question

What you define as “carbon scrub”?
Adding activated carbon to solution, > then filtering it out
OR (like CRC) it’s column filled with activated carbon medium > thru which we filter solution?

tried to search, but i guess lang barier or something won’t let me get exact definition, even google gives me “carbon” cosmetics

Carbon scrubbing is indeed bringing the solution in contact with the solution

The question then arises what is the goal and how well is carbon at preforming to achieve this
Sadly activated carbon comes is many many flavors and there is not one that stands out
In general hardwood activated carbon has given me best results in powdered form
But this is the hardest to get completely out of the solution whether used as a powder in solution ( longest contact time) or as CRC stack

One of the main disadvantages of carbon use is discoloration of the tincture to reddish color
This can sometimes be revursed by taking the solutions ph back to neutral
A procedure that should be done with care since if solution gets heated somewhere in the process

I personally try to use activated carbon in granular form rinsed prior to use with the same solvent as solution to have as little as possible work in powder form since the chance of filtering it off is hard
Tampon TEC works best even if it s in the stem of the Büchner funnel

Remember that
Activated carbon holds on to accitic cannabinoids
Rinsing after use with clean solvent helps

Carbon scribing at elevated temperatures works better but isomerization lurks since it s often accitic in nature 80C

I guess my main message is if you really have no other option activated carbon can be used
But if you do not have to avoid it

As for cleaning up alcl3 reactions it has little use so far
There are probably AC that can absorb chlorinated cannabinoids but I have not found one there are easier and more effective solutions to that problem
