cooking at low temperatures under vacuum is limited to one success and also identified flaws and needed upgrades to the test sled.&nbsp; After trials to establish boiling points of water and alcohol under vacuum, the modified pressure cooker that I was using, lost seal integrity, so clearly the seal was not neoprene, nor compatible with hot ethanol.<\/p>\n\n\n\n<p>In the spirit of repurposing where ever possible, and as extracting some of the terpenes and flavonoids involve using ethanol, that led me to sort through the sanitary equipment that I have on hand, and to cobble together a 0.7 gallon welded bottom 6\u201d X 6\u201d sanitary spool, a 6\u201d X 6\u201d sanitary spool to extend it to 1.5 gallons, and a welded bottom 12\u201d X 12\u201d sanitary spool holding 5.7-gallons.

all of the parts I needed for the 6\u201d systems, including a 6\u201d lid from my original prototype Lil Terp BHO extractor with the required plumbing, so rather than build a separate lid for the 12\u201d spool, I elected to use a 12\u201d X 6\u201d sanitary endcap reducer with PTFE seals, which allowed me to transfer the 6\u201d lid back and forth.<\/p>\n\n\n\n<p>Alas, the only thang is that I didn\u2019t have was a 12\u201d X 6\u201d sanitary endcap reducer, but as a seasoned scrounger, I initially borrowed a Transforminator lid from kindly Carla Kay to keep the project on track, but kept looking, and imagine my joy and amazement when Glacier Tanks in nearby Vancouver, WA was gracious enough to accept one of my plain NOS 12\u201d lids back in trade for the reducer that I purchased from them in 2015.&nbsp;<\/p>\n\n\n\n<p>A nice gesture from a good place to find sanitary parts for the botanical extraction and brewing industry.<\/p>\n\n\n\n<p><a

href=\"https:\/\/www.glaciertanks.com\/extraction-tanks-lids.html\">https:\/\/www.glaciertanks.com\/extraction-tanks-lids.html<\/a><\/p>\n\n\n\n<p>My first vacuum cooking experiment was Jalapeno Lemonade, which required alcohol recovery and so I used the EtOH Pro on loan, alas to find that I contaminated the internal plumbing with Jalapeno flavonoids and capsicum, requiring multiple flushes with clean 190 proof, which was then contaminated and limited in use.<\/p>\n\n\n\n<p>Sooo after getting the EtOH Pro clean again, I decided to add my own condenser system that I could dedicate or more easily flush.<\/p>\n\n\n\n<p>In that regard, I &nbsp;&nbsp;added two condensers to the test sled, one a fan cooled copper tube radiator and the second a 50\u2019 \u00bd\u201d copper coil in a water or ice bath.<\/p>\n\n\n\n<p>The radiator is a single copper tube 10 pass heat exchanger with aluminum fins built by Derale, with a 12 VDC cooling fan scavenged from a different Derale fluid cooler.<\/p>\n\n\n\n<p>The radiator heat exchanger can be used to remove water vapor from the discharge, so doesn\u2019t require a hood to capture the steam indoors.&nbsp; It can also be used alone or in conjunction with the water bath coil heat exchanger for recovering alcohol.<\/p>\n\n\n\n<p>The water bath coil is capable or recovering alcohol on its own, but uses less cooling water or ice if the stream is primarily liquid when it reaches its inlet.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img data-recalc-dims=\"1\" loading=\"lazy\" decoding=\"async\" width=\"525\"

ethanol vapors, all of the seals and hose used in the hot sections are PTFE, and the hoses between the pump and the liquid cold traps are nylon lined refrigeration hoses.<\/p>\n\n\n\n<p>The PTFE hoses in the hot sections are all 3\/8\u201d with 304SS stainless over braid, using stainless 3\/8\u201d female #6 JIC ends, mating to stainless male JIC flare connectors.&nbsp; I obtained those hoses and the JIC fittings from Associated Hose, here in Portland.<\/p>\n\n\n\n<p>I used Viton gaskets in the vacuum filtration unit, as Viton is compatible with ethanol at ambient temperatures and is more resilient than PTFE.<\/p>\n\n\n\n<p>I used lead free brass bulkhead connectors in the liquid trap lid on the cool side of the heat exchangers, and both the radiator and the water bath coil condenser are copper.&nbsp;<\/p>\n\n\n\n<p>Hee, hee, hee, currently awaiting a couple final parts and then ready to proceed with the culinary
