You could try to add ~0.3% Tocopherol or L135 Antioxidant to increase the lifespan if the oil substantially in case it oxidises too fast
Immersion mining with canola oil to concentrate maple sap more quickly
https://v.nostr.build/n997.mp4
I'm using a single S9 hash board immersed in canola oil to heat maple sap to increase the effectiveness of the reverse osmosis sap concentration system.
The weather conditions this season have caused the maple sap to be cold and stay cold which drastically slows down the ability of the RO system to filter water out of it. I ran into a bottle neck where there is more sap than I can keep up with concentrating so I needed to come up with something quickly!
Ideally if the temperature of the sap is 77°f the filter will operate most effectively without damaging the RO membrane. Of course, my mind immediately turned to Bitcoin mining for the heating solution. What I came up with was an immersion system using the homebrew equipment I already had to heat the sap just before it entered the RO. This would allow the majority of the sap to stay cool keeping it from spoiling and still remove the most water possible.
The only thing I didn't have for the immersion system was the dielectric fluid. I had no idea where to find the proper fluid nor did it make sense to pay the high cost for it. The application for this system is very specific and I will only need it until April. I had been joking about using canola oil as dielectric fluid for almost a year but for this situation it seemed like the perfect fit. Canola oil is 70% cheaper than bitcool before shipping and was immediately available!
Amazingly, I put everything together and it worked very well without major adjustments. I tip-toed the voltage and frequency of the single S9 hashboard up slowly to find the right balance in temperatures between the two fluid loops. Ultimately, I ended up with an overclocked board drawing over 600w! By the time I got the system setup and dialed in I was already half way through concentrating this collection of sap. The next collection will offer more concrete data on what this system is capable of. For now, even with the worst S9 board I have, I'm getting a 15% rebate on the total power usage of the whole process and it's definitely concentrating sap more quickly. All for ~$10 of canola oil... 👀

Is tocopherol just vitamin e oil??
Yeah essentially the same, its a oily substance. Just don't use food quality supplements, but technical quality with high concentration, way cheaper. Its also used in the lubricant industry as AO for lubricants with possible food contact.
Part of my experiment is to use whats available immediately/locally. The liquid vitamin e oil from the grocery store won't work?
If its concentrated enough it will also work, don't know if its diluted or pure. I would add around 0.1-0.5% pure Tocopherol of the mass of canola oil, if its diluted, for example for 50% concentration just use double the amount.
