Interesting @WhereAreTheStones nice post!

I have floor drains in Oregon. Your floor drains should always have water in them creating a seal from the connected drains/rooms. If you dont put any water down a floor drain for a few weeks the plumbing could dry up but the issue isnt solvent getting into the drains since you should have a negative pressure in the extraction room.
The issue is the negative pressure will pull sewage vapors into your extraction room.
If you have floor drains use them at least once a week, I have a sink at the furthest part of our facility set up to drain right into the floor drains to ensure there will always be some water flowing into the floor drains.

Our Drains have to go to a collection res for testing/haz waste removal (cannabis biomass potential, as if!) before allowed to go to sewage here.
Thatās a SOLID tip for those who donāt have to deal with excessive local JDs.

We have a āgrease trapā as well at the end of our floor drain plumbing. It was a total bitch to deal with the city on this part of the build out though.

I donāt understand how perlite is better than a vacuum jacket.

Iām not sure how well it performs tbh. Regular perlite has an R-value of 2.7. I believe a 1 inch vacuum jacket can have an R-value of 25 or greater. This ācryogenic perliteā is a finer consistency like sand. I canāt find any info on R-value, I just know itās used for cryogenic vessels and double walled pipe.

Iāve got some ideas for improvements to jackets and column closers.
Mainly to extend the liquid jacket and the vacuum jacket to within 1-2mm of the gasket flange install clamping flanges on the od of the vacuum jacket. Example; 4ā diameter column double jacketed and clamped with 5ā or 6ā triclamp. 4ā viton gasket in the center. 5ā or 6ā felt āgasketā the outside flange. @Indofab

Hi,
@Indofab isnāt really active on here to speak of,
This is doable, the fit-up of the components would be pretty critical in the assembly. Is this something you want made?

Just a pipe dream for me. And Iām actually not in love with triclamp. Iād much rather see a o-ring seal like split flange hydraulic where they bottom out metal on metal with the seal between. Or something you give a quarter turn to lock on like a pressure cooker lid.

me neither, the way extractors are built is about to change in the next few years.

might be a shot in the dark, but you could wrap them in PigMat. itās adhesive-backed absorbant material, iāve only used it on floors but it does a good job of soaking up and distributing water in a nice wide surface area for better evaporation. may or may not work whatsoever
Iād like to see a hydrocarbon extractor one or two pound capacity specifically for home use. -40 to 100 degrees. No tools required operate. No gaskets. No gauges. Re fills from those little cans we donāt open blast with anymore. I think we can do it. Safer than a bar-bq. Quiet as a refrigerator. Of course you probably wonāt make diamonds in it. And for safety it wouldnāt open till the solvent is completely purged from the extract. But for home growers who extract occasionally and arenāt in a competition over lbs per minute recovered. A passive plug n play push button rig would be cool.

I would like to see the feasibility of maybe a hammerseal unions on extractors instead of using tc fittings.

why? Seems like a great way to reduce the compatibility of your system with a whole swath of off the shelf parts.
If itās pressure that concerns you, just stay away from 12 inch TC fittings.

Personally I am not concerned with compatability. I am looking at ease of setup and breakdown would not have to have a torque wrench involved or replacement of nuts and washers on fittings anymore. I am just putting ideas out there. In the world of sanitary stainless steel fittings there are a lot better options than triclamp in my professional opinion.
To be fair, I canāt argue thereās not better fittings than dairy and beer fittings. 
Luna Tech also went in a different direction for their material column, with the idea thatās the part youāll be opening a dozen times a day to input a new material sock. You might like taking a look at that, looks like no tools to open.
