The body for the delta is set at -30 ethanol was chilled for about an hour before use with dry ice. Which I dont think was close to cryo temps
@Demontrich so I should cryo wash the crude again correct? Then stick to the same process 
I think not getting down to the proper temp might be making the spd more tedious to do.
I would say you also have a vacuum leak if you’re sucking distillate into your cold trap
How much crude do ya have?
Maybe do a small test batch vs the whole batch.
This way you can see if it needs winterized or not.
About 50 liters of it. Which is alot to me right now…
I gna try to do 15 liters of it for a run in the spd.
So I plan on doing a 3:1 ratio of ethanol:crude, winterize (dry ice for 8hrs) all I got right now. Then filter it again and run through the evap, decarb again and run through the spd.
Or do you think running as is will be better option. With right parameters.
I’m just trying to figure out how to process these liters asap. But iknow if not well prep its gna make the spd hell.
If winterize the crude is better than wasting time (not really just dont have that equipment rn other than trying picking up small scale processes) trying other methods to clean the crude as much as possible.
@TrillOrganics vac was under 500 micron the whole time. I also didnt get head condenser at a near enough temps which I think pulling
I’d grab 1x 1500ml (half gal mason jar) and do a winterization on it and see what happens.
You can also further it by using a buchner funnel (fritted disc) and celite 545, AO. If freezer cold, the AO will stop lipids and waxes from being filtered.
1500 crude: 3000 ethanol. Then stuff that into dry ice.
AO?
Yeah keeping it cold is my biggest problem w/o cryo freezer.
AO = alumnium oxide (180 grit iirc)
Freezer cold filtration will keep the lipids and waxes on top of the AO. You’ll visually see it.
2:1 ethanol to crude is going to be a little thick for filtering. Between 8-10:1 is going to treat you much better.
Thank you, does the theory I’m using sound ok?
Diluting the crude, Winterize and then filter again? I don’t have any type of media to run it through rn.
I might need to get a smaller filtration system to play some r&d as the pig system I have rn its huge.
I believe I have spd part down. Not too sure of myself as each time (4th overall) I’ve run into an issue.
Thank you all for your help and advice.
not only will 2:1 be hard to filter as @cannabuilder points out, you would likely also drop cannabinoids at -80C (which is where your dry ice bath will get you).
somewhere between 5:1 and 10:1 is a safer range to winterize. Ethanol Ratio During Winterization - #2 by Future
@elgallonegro what was your head temp and Vac level?
@TrillOrganics I don’t understand how a vac leak could cause distillate in the cold trap.
at least not with the mantle at 210C.
can you enlighten me? (no experience with leaking glass 
)
Thank you @cyclopath I used an 8:1 ratio.
My head was at 40c the whole time which was another nono that I was doing. The vac level fluxutate around 480-500 micro.
@cyclopath I’ve seen a leak or three that basically just ended up sucking the good stuff all the way into the pump. I guess all those leaked air molecules plus high temps allowed enough distillate to make it all the way through.
I have to say they were relatively large leaks. It must have been Helen Keller’s day to set everything up
If you ever want to talk about how much fun cleaning distillate out of KF25 bellows can be let me know…
All good advice above. I have successfully winterized in a regular freezer (ideally a chest freezer because they’ll get down to -10 or -20). Just give it at least a full 24hrs in there in the small jar. For the sake of R&D and you don’t have any other filtration gear, simply put a funnel with a coffee filter in a second empty jar and let it gravity drip. It should be pretty apparent if you need to winterize the rest. If you get that far and do need to go bulk filtration, I can give you some pointers on using the pig to do it well.
@cannabuilder so for an r&d run
Did an about 8/9:1 ratio in a 15 gallon delta keg.
So ruffly 7L:~50L had to leave some space to agitate ( keg lifts/presses/stands/shakes for two hours, basically sore as shit right now) since we dont have a stirring contraption.
Then left it dry ice for 10hrs and filtered it through the pig
Hello Elgallonegro, on the filtration side, we do have filters that might be more efficient at removing particulate. Your batch size is small (~ 12.5gallons) so I would use a small bag and bag housing as the first step. You can use various micron ratings, stepping them down as you go. Say 25um, 10um, 5um. Then for your color removal, we have carbon cartridges for that. Just let us know if you need help on these. Thanks, Greg gregh@heyesfilters.com
You pretty much nailed it. And you are definitely filtering a bunch of wax out and should keep it going. Are you using any filter aid with the pig? The pig has 7" plates, right? Mixing in 4-6 cups (start small) should give you a bit more filtering depth and can probably get through at least 1-1/2 kegs per filter run. Don’t push it too hard and clog it mid run, I know you have a lot to get through. This is a great source for filter aid (super cheap shipping): Filter Aid
Looks good to me. 0.5 micron is too small. You don’t need this small for wax.
Also, you don’t need -80C, just leave it at -40 for longer time, the result is the same.
Good luck
Brute force huh? Been there.
There are other ways of mixing it up in kegs…
Except those Delta kegs are based on yeast brinks And have that 1.5” ferrule down low on the side…so methods 1-3 are out 
There are cheaper places to get it. Don’t get fooled by the DC408, which is shorter. Or get one that isn’t stainless.
Put it on a decent drill and it will do a great job mixing biomass in a keg too.
@cannabuilder yes the pig has x10 7" plates.
Not currently using any aid with the papers. But will definitely get some asap. Thank you for the link!
How many times is would be a filter it out? I was thinking 1 to save time for rn
@jimmytian8 yeah this was only micron we had on hand at the moment. Plan on doing a 25 micron first than winterizing it for the .5micron. Or should I be winterizing prior to the first pass too? Atleast for the biomass. Gna have to winterize the rest of the crude “again”
@cyclopath haha yeah I was thinking the same thing. Just did that for the moment but plan on definitely getting that for homogenizating it
Smoky Lake Maple Filter Press - 7" Short Bank Stainless Steel - How To and Review - YouTube the second half of that video will give you a good idea of how to run it with the DE mixed in. The recirculation is important to building the filter cake properly. Go ahead and use the .5micron paper to pick up loose DE while you’re getting your technique down. You can actually add a bit more than I initially told you, around one (8oz) cup per plate. When you’re done filtering, run a 5 gallons of chilled clean ethanol behind it.
