    So now having built a lil terp with 2×36″ column purging seems to be a bottleneck for me. I came up with an idea. I have a commercial conveyor pizza oven at my disposal that has a low temp of 50c. The oven is around 48×36″, and I was thinking I could find a stainless tray about 3″ deep and put a sheet of whayever the best material is beneath it, line it with parchment paper and leave it hanging out a couple inches to accommodate flare fitting and vacuum hose… just want to hear your thoughts on it, I plan on purging after recovery to cut down on bubbles blowing up too hugh, but really want a vessel that can purge 12-15oz at a time and prefer the layer to be paper thin during purging, also equipped with a walk in fridge and pondering cooling oil then flipping it to throw back in oven and free up anything that may be trapped in the lower layer under the less viscous topside. Also, if you may know of a stainless tray that fits the bill, please let me know. Im going to start looking at what is available in the food servce industry, though I may have to make 3-4 smaller vessels, which wouldnt be a problem, I could just Daisy chain them on one pump.


    • I’m not visualizing how you are vacuum purging using a open tray? Could you elaborate?

      We do a full thin film purge in one shot, so there is no need for a freezer. It might be handy to cool it down faster afterwards, if you were running volume.
