If it’s sticky than you probably haven’t taken out all the butane out or your extracting operation is picking up to many impurities. I can get How does your starting material look like? The first picture is from trim that was up in the mountains in a garabage bag for 3 months. The last pic is same technique but with great starting material. You can get stable shatter with old material if you’re operating correctly.
If you can’t afford a freeze dryer invest into a dehydrator. You’re loosing weight if your material isn’t dry.
Now if all else fails and could be a good possibility since you smell terps is that you can’t stabilize it due to the high terp content. For instances a headache strain is GG4. I believe certain terp profiles or possible to much terps will not stabilize shatter. It’s a theory. I never had analytical equipment to confirm this.
Are you using a hydrocarbon blend or straight ISO?
Wouldn’t you be loosing THC if you dry ice a day before? Or you drying and vacuumed sealing the column first? I use to dewax with dry ice slurry 1 hour before my run while continual pulling vacuum.
No what I do is get my dry material (not aiming for live) freezing on dry ice 2 hours to a day before extraction. Get my stainless steel solvent/recovery tank balls cold in a cooler of dry ice for about 2 hours. Take tank off let it build back up to room temp and let her flood and extract the room temp column.
I’m a Passive 1lb of material run kind of guy. So I just use the standard cls bho SOP.
Remember solvent will move from more pressure to less pressure. At the same time if you know how to manipulate the valves you can siphon the hydrocarbon out of the recovery tank. This requires a cooler ambient temperature in the room. and a coil heat exchanger before your input solvent feed into the column.
Can i ask do you overhead shower or bottom flood?
Also check your PPM off the valves every time you take it out of the cooler.
They have a more efficient way to do this. Your recovery tank is it single, double, or have no wall?
Ill help you. You’re channeling the solvent through the biomass via your current method. In other words you could be getting better pulls. The only set back is you will need a bigger collection vessel via bottom flooding. You will need this because of how much solvent is needed to completely extract everything off the biomass. Let me get some of info together on parts and a PID.
Bottom flooding will ensure no channeling. Give me a bit ill draw this thang out and will be easier to understand. BTW you dont need a bi directional manifold.
Also with retrofit. Are you talking about insulting the system?
No, I’m talking about teeing off the gauge on my base with a prv and adding the 4 way tee on the top of my system and teeing off the injection ports gauge and adding a prv there as well. My tank already has a prv and gauge
I’m broke af for new parts right now and I don’t really wanna upgrade to bottom fill or bi-di. I’m pretty happy with top fill. I was just giving input. Though, once I make or buy a rack I’ll most likely switch up my set-up for bi-di and go bigger collection.
For now I just wanna retrofit my system for nitrogen so I can extract in a dewaxing column and push through a low micron filter.
