Fresh Frozen Ethanol Extraction: Whole Plant Versus Biomass Trim Yields of Distillate

Remember I’m the FNG :grin:. Why not just blast all the live material, purge all of your solvent out then mix with some warm ethanol to make your distillate?

Here is a pic of my hose/valve/nozzle that I found used on Ebay for $159.

Sorry but I have no other pics. Super simple. I just hooked up the hose to my low pressure dewar. Put flower in a 30 gallon drum turn on the LN2 and spray the LN2 throughout the material. After a few minutes I stop the flow and then use a paint mixer hooked up to my drill to break down the cannabis. I would simple repeat a few times then quickly through that material in the freezer. I quickly learned that it is best to open the dewar line than before opening the valve place the nozzle all the way into the material then slowly open the valve to avoid blowing material everywhere.

brand on. That hose/nozzel ?
Is iT specific to Ln2 ?
Thx

I’m curious how freezing plants is more cost effective than drying? Drying takes a couple weeks hang + couple more to lock in a great cure, while in quarantine. Afterwards, it can be nitrogen sealed or conventionally packed with a decent shelf life. Freezing costs would accumulate indefinitely and the equipment costs to do this on a massive scale would be nuts. I totally get it for farms segmenting portions of their crops specifically toward terp sauce, etc. For distillate or standard (still very terpy concentrates). I just dont see it.

I’m curious as to how you guys would go about drying a few hundred pounds of fresh frozen trim at a time? Also if your end result is distillate does it matter if you flash dry it and do not worry about the cure?

So if you used a LN2 conveyer flash freezer woth wet biomass then immediately bagged it and vacuum packed it, the material would be dry? I guess I’m asking, will the vacuum packing process (nitrogen flush if needed) pull the moisture out?

It would never be turned into distillate to start off with. :man_facepalming:t3: Hundreds of lbs of fresh frozen trim would be made into diamonds. Ohhhhhh.

Can’t believe I just read that.

No, the LN2 does not dehydrate the biomass. The cost of freezing whole plants as opposed to paying trimmers is staggering. The average cost per # was $100 to hand trim. Last year the cost was down to about $50 per #.

As @BG305 said freezing does not dehydrate. It’s rather simple. Freezing freezes, dehydrating dehydrates. To remove water you have to dehydrate. To freeze the water and lock it in, in order to avoid extracting it and all the water soluble compounds that will come with it, you should freeze the material and to maximize that process flash freezing with LN2 is a preferred method that is rather easy to do. Flash freezing quickly freezes water and as a result of the extremely rapid temperature change, the formation of water crystals tend to remain small. Compared to the use of a regular freezer where the formation of crystals tend to be much large. The reduced water crystal size minimizes the negative impact on extraction. Simply put if you freeze it needs to be done as fast and cold as possible. Once frozen never thaw and refreeze, ever. that is a sure fire way to ruin plant material, especially for Ethanol extractions.

That said if you use frozen material your extraction vessel and solvent need to be at the same temperature as the frozen material otherwise the material will start to thaw and fuck up your extraction.

Vacuum sealing just removes oxygen to help preserve quality.

Why would you do that? It’s a waste of fresh frozen and a pain in the ass. For what ever crazy ass reason you’d want to do that I guess your best bet is to through it in a massive forced air dryer to thaw and then throw it into a massive dehydrator to dehydrate at low temps to preserve terps and avoid decarboxylation. I guess you could do the whole thing in a forced air oven but Im not sure how well it would work at temps low enough to not decarboxylate. If you are thinking of using fresh frozen for distillate you should be ashamed of your self :neutral_face: All those wasted diamonds and terp sauce!! What a shame what a shame :rofl::joy:

Even lower trim costs further, buck it and bucket. Bam, done!

I said that a few post up and erased it because this thread title specifically states distillate. I totally agree with you though…There are miilions upon millions of boof lbs of biomass. Why take top notch material and make the absolute most labor intensive and cheapest product on the market!

when diamonds is probably the least labor intensive and fetches on of the highest price. Its just a tad bit backwards.

Customer wants it turned to distillate

seems like that customer should be educated on maximizing the profitability of concentrates.

for both of your sakes

I probably won’t take it on. They freeze the trim out of ease going from wet trim machine to the freezer

free money is free money…if the material makes sense then it makes $$$. I just think processing it into the most ideal concentrate would be the highest margins, but if you can run it and make money off it…there is no ego in this game…run it fast and get it out bro…

We are just pulling your chain a bit because its sort of a waste to remove all that goodness that makes fresh frozen trim desirable.

I’m more worried about the labor and effort involved drying out a chest freezer full of trim. Maybe I’ll tell them to dry it out before bringing it to me but these cats might screw it up trying to dry it out it cause it to mold so I don’t know maybe I’ll just tell them I don’t want a dick with it

I figured , just poking fun no hard feelings. I totally get it, you gotta do what you gotta do. You are for sure going to need to up charge for the extra work.

It just seems so difficult and costly to dry frozen material any potential cost savings is gone and I’d bet you’ll end up spending more after factoring in all the time and effort.

I think your best bet is to run it as frozen. Then take that oil and turn it to distillate. Heart breaking, absolutely heart breaking but most likely the easiest way to get er done.

60:40 split maybe even 70:30 to account for all the extra labor and pain in the ass! Make em pay for it that way they stop making bad decisions. You can for sure run it frozen then just turn that into distillate. Maybe set some of the goodness aside then after you convert the rest to distillate do the math to figure out the conversion rate. You can then easily calculate what you kept and deduct it from your split?
