I was curious what solutions people have for direct filtration of oil, in the absence of solvent. Like say you broke a mason jar and wanted to get all the small glass fragments out of the oil. Or if you wanted to do direct bleaching of oil and then filter the clay out, as is done in the food oils industry. If you keep it hot enough, you can send it through a buchner funnel, but this is difficult on large scale and i’m wondering if anyone has found anything better. Considering everyone’s car has a hot oil filter, i’m sure there’s a ready made solution.

when you put it like that, it certainly seems like we should build one if there isn’t 
the stainless “water filter” I posted in the blue filter thread is good to 250F
not sure about the wound filter elements…
My biggest issue with bag/cartridge filters in this case is the hold up volume may not be considered an acceptable loss. In this case the smaller the unit the better.

have you found an effective solution to this? asking for a friend Thanks!
For THC no terps, heat in jacketed vessel with 1.5" TC and valve on the bottom under significant vacuum to prevent oxygen. Install mesh gaskets or expand to sintered disc. Once up to an appropriate temp for viscosity stop vacuum, backfill with nitrogen or argon and push the THC through the filter slowly.
For THC with terps you nitrogen or argon purge, vac down, re-purge and heat with nitro or argon in the headspace. Then push through you filtration.
The main point is you have to heat the product, and that means no/low exposure to oxygen.

chem techs sweating baskets work for getting most particulate out, i have had some contaminate get into vape formulation and used them to filter it and it passed foreign matter testing. i just seal it in a 6in vessel and purge with nitrogen then throw it in a vac oven at like 40c over night

Nothing made by a factory for the purpose, just various DIY solutions. I have done direct filtration of oil with a membrane. You can see those results in the membrane oil final product thread. But that’s not really what I was talking about in this thread, I was thinking more like the oil filter a car uses.

Problem is viscosity at room temp IMO.
On a large scale this is tough, on a small scale keep the destination glass jar and filter/filter media above a hot plate to keep everything nice and warm and just let gravity do its thing overnight. Buchner+vacuum only works if you can keep all of the filter area covered with oil and with as viscous as cold oil with entrained broken glass or other particles is that’s not going to happen easily
