Yes, I would wanna filter before wiper. Numerous times I have found metal shards inside of isolate post-decarb.

You sure it’s not the wiper contributing the metal shards into the isolate?
Especially from the hanging shaft style design that thing can really slap around in there…
I have personally seen our bottom held shaft design flex under high loads…
Edit: it is basically a double I-beam and has great rigidity…
Which ours is connected both top and bottom with FDA bearings in the wet area…
Just imagine what a free floating shaft is doing at times? 
Second Edit: I have also seen them dump out 1/3 of a 55gal drum from one GD1. Which personally I feel is definitely overloading the system. Takes about 30-40 min to pour out under a little pressure with CBDa.
Rogue, you are the master..of the AMINE TEK with pH Manipulation.
Alkane up front Yes. But I am curious if you find the system fails if you begin with Alcohol crude. Once you get the Polar Protic water and alcohol associated with the Cannabinoics , it creates down stream problems concerning crystallization. Does the AMINE step cure this for Alcohol primary step as well?

Don t know I always use alkane s as extraction solvent and basicly have not found crude ethanol extracted that was worth trying since it s mostly decarboxilated

I know for sure that with iso-propanol ( ipa)
It works

BTW: anyone who can put out 600 Kg a day of CBDA (cannabidiolic acid )
Using a few stainless containers, a HDPE container and a mixer of sorts..deserves an honorary Ph.D. In cannabinoid chemistry. So from now on it is Dr. Rogue as far as I am concerned. If anyone the community agrees , give the like button a push.

Anyone care to help? I use an ETS MeP30 with pour spout bowl, and usually 100% propane. I would like to fast/cold crash thca inline. I do not have a mixer or isolator and obviously there’s no budget.
Is it possible to recover cold and crash thca onto walls? How to avoid clogging 3/8” pour spout? I have extra heads and honey pots and a jacketed 9” column I could make a miner with, but id like to fast crash if possible.
Any tips or spoons would really help. Im stuck in “idea limbo” and nothing is working.

Yeah you can cold crash in just about anything especially with high propane runs. Just don’t add heat to your basin when you recover.
The mixing aspect makes it cleaner and faster, more consistent, etc.

Thanks Zack, any tips for not clogging the 3/8” spout at the bottom? If I do low heat at the very bottom would it only crash higher up on the column sections that arent heated? Also need to sort out where to add mesh to filter.
Without agitation you’ll be producing what amounts to a large brick of -a that will not be fun to remove and will be heavily saturated with your aromatics fraction. Agitation can come from a variety of places, and some forms work better than others.
For low cost… pipe to positive pressure and bubble it.

Thats gold thank you
We’ll see this with n butane running the heater at 85° F, if we recover hard and don’t maintain positive pressure. Kill the heat and it will start crashing like crazy.

Not ideal, but worst case if you clog the spout you can poke a hole through and still push the bulk of HTE out with N2. Then drop the bowl and remove the THCa.
I’d look into a dedicated set up if you plan on cold crashing regularly though, because as mentioned it

Interesting! Yes I do have a few spare ETS parts to make a crash column with. I do like the option of bubbling it as agitation. I can use propane vapor to do so since Im already 100% propane. Just need to wrap my head around preventing clog and then being able to rinse the -a after crash. Would 25 micron gasket work or do I need sintered disk?
I rinse with cold -40C pentane purging takes a bit longer
