Passive Recovery Time


Random q but someone in here may have a good answer for me… did a trim run for a client and concentrate came out a bit dark, he had a decent amount of fan leaves in there so I’m figuring that’s why. I run 70/30 tane/pane mix bi-directional. Only other thing I could think of is that I let the bottom soak sit for too long (no more than a minute or two). How do I politely explain to a client that I can’t work miracles with his trim?


Try getting into this thread and see what miracles you can pull. Horribly stored good material comes out amazing.


Did u blast cold cold…if so there’s nothing more you can really do

Trash in , Trash out!


Didn’t use my dewaxing column but ambient temp was in the teens and the gas was ~17*F. Looking at using my dewaxing column with N2 assist in the future but funds are low.

First client, so I need his business!

Can polish a turd, but it’ll still be a turd.


Yep I’ve read most of it and am looking into utilizing the tek there, waiting for funds to come in before investing in the S.S. I could polish post extraction with ethanol wash in carbon, bentonite, and silica but that would prolong my turnaround time and I’m not sure if I’d be able to get a stable shatter from that.


Keep it in the butane it works far better. And depending on the strain, they seem decently stable so far. Couple turned out really well.


This was my first run with his stuff so there is a learning curve to be expected when working with new material. Got several things to try and play with, but definitely have to throw more money at it!


we have so much gas flow our molsieve rattles in the column. passive speeds are intense compared to the tiny stroke of a compressor.


I was under the impression that active was faster. I couldn’t imagine running recovery any faster!! I recovered 8 lbs in less then a half hour.


That’s approximately my goal, hell, I’d be happy with 10lb in an hour flat.


I recover an average of 1lb a min, on standard runs. I can smash up to 2lb when i’m running crude


I wish I could recover that fast. I can get a lb every 4 to 5 mins with a pump


What solvent are you using?


Usually iso, but 7030 ntane/propane


When I ran 70/30 (twice) my times were similar to yours. Are you vaccing down your lines?
Edit nvm your running active. I was getting that running passive


I’ve noticed my colors get darker once material stored in a Turkey bag homers much over a month old, also not regin the sieves enough, I’ve soaked mine for up to 10 minutes using dry ice iso slurry cold butane and a open jacketed column with dry ice in it, and had it come out as golden as any I’ve made yet
5 minutes soak using a regular column still blonde
Age of material and sieves are the two things I’ve noticed play the biggest role in color…

I want my recovery a bit faster also and I think upgrading my recovery tank from the standard carbon tank with 1/4" lines to a SS one with 3/8" lines
My recovery time cut in half once I started completely burying it in dryice with iso about 1/2 to 3/4 up it.
Doe you use nitrogen to push?
I’ve seen my recovery have issues if I dont vac it completely out of the system…
I recover 15 lbs in about 45 minutes…


Just get a condenser coil for injection and recovery. no need to dewax anything and no need to bury any tanks in ice. The only thing that needs dry ice is the coil. Also having a purge line on your recovery tank open while your recovering helps. Doing 30lbs in about 45 mins. passive. Also have water flowing in my jackets at 130f no terp loss. Fuck all those water heaters just get a tankless water heater and your good to go. You can set it to whatever temp you want. Keep it simple


I dont agree with this. Me and my friend have tried both ways, he youst to like the coil for recovery too. I have a coil, i put it in between my collection pot and my recovery tank. Filled with dry ice pellets and 99%iso alllll the way up. Still had recovery tank covered in dry ice. Took an hour to recover about 6 lbs, and the last pound took the longest. I did my run without it using just a regular fish heater and aerator pump and noodle strainer to keep collection pot from being froze to the bottom(allows warm water underneath) and recover 7lbs an hour constant rate, last pound as fast as first. Even the non dewaxed 2nd washes come out fast and clean.


But definitly the coil is the bomb for injection, getting that tane nice and chilly


Well it works beautifully every time i do it. what temp is your water at? My entire recovery vessel is jacketed. I let it get to about 50 psi and open the valve and it goes into the coil great the whole recovery. i have no tanks on ice nor is my recovery tank vacuumed. 25-30lbs in about 45 mins or so
