  1. Vapor in Column Backflow

    in the bottom of my columns the downward liquid flow seals the down of the column which then drains from near the bottom of the column this "backup" functions as a kind of trap with separation from the in flow of high temperature vapor.....the tube returning to the pot was not uncovered.....
  2. Vapor in Column Backflow

    is it possible you are driving it too hard and not allowing for the entire column to stabilize or the defleg is too cold and rejecting too much product and flooding the plates?....happen to have a laser temperature gun to check temps of plates as vapor goes higher and higher?
  3. Vapor in Column Backflow

    my pots had a return well into the pot....the path was up through the helmet and over to the bottom of the column....the liquid from the downcomers draining out of the very bottom of the column and the vapor input 3-4 inches off of the very bottom of the column.....so when running the "seal" was the liquid in the bottom of the column... What is the diameter of the return to the pot? ru not doing something like mis-configuring the valves right? so another silly question: did the manufacturer commission your still....has it been wonkly from day one? If you have a grain in mash the return could be plugged with solids from previous runs and not allowing a return...
  4. Vapor in Column Backflow

    if the liquid return path is above the liquid line in the pot, both paths could be feeding vapor....
  5. Vapor in Column Backflow

    Are there two paths to the column....1) for vapor and 2) for condensed liquid being returned to the pot?
  6. Plastic vs Stainless tanks

    So shipping in plastic IBC's is just fine but the second you take them off the truck you may be stuck....also you must ground the SS IBC's.....if your OSHA inspector doesn't cite you don't beg them to cite you because they just might....also when moving them or wood barrels around your facility you "must" use a rated forklift....but I am sure no one will believe this either....maybe we could make a new Mad Max movie....ya know driving a tricked out flaming IBC through a rick house!!!
  7. Plastic vs Stainless tanks

    It is against OSHA regs to store high proof spirits in plastic totes...shipping across country in the back of a semi-trailer is just fine. Your tax dollars at work
  8. Flow Meters

    https://www.zoro.com/search?q=flowmeter&page=3 zoro has a bunch to consider depending on your needs
  9. Flow Meters

    http://www.omega.com/pptst/FP2001-R.html Grainger... FILL-RITE 6 to 40 gpm Liquid Mechanical Flowmeter Item # 30J080 Mfr. Model # 900CDBSPT Catalog Page # N/A UNSPSC # 41112501 Make sure you have approval for all wetted parts to ethanol (solvent).....you should consider EX or ATEX rated considering you have a potentially flammable/explosive situation
  10. Steam Control

    Steam is not a popular as it once was and it may be hard to find a local plumber or PE that can guide you through the layers to build a safe, inspected, code compliant and efficient system. Probably could be looking at efficiency as the underlying factor. How fast can you get to operating pressure? Is your code compliant boiler room large enough to service the tubes? Can they be changed out by a local company (or on site engineer) or would the re-tubing require fairly exotic tools and factory support and re-certification inspection? Look at the used market. We found a great boiler nearly new but it was 2500 miles away.... You could consider hiring a chemical treatment company to come in a add boiler/steam (buffering) chemicals and perform monthly testing to reduce the corrosion of the tubes and steam lines with controlled blow down systems. Boilers need combustion air supplied from the outside of the building and isolation from sources of fuel. Are you going with low pressure steam or high pressure steam? High pressure steam is quite a bit hotter and may allow you do do cool stuff like generate clean steam for direct injection or flash cooking but may require a higher hurdle for licensing, operation and inspection. So what is your time line and expansion plan or are you just trying to get out of the dirt? You might want to review the inspection/operating/pressure certification (AHJ) license requirements for what ever system you use.

  13. Steam Control

    You can use two smaller boilers each with its own set point so only one will run when you are in the 'heart' or the low demand portion of the day and both will operate under startup conditions like the start of the day or a mash cook. There are modulating burners (powerflame, etc.) that can be set to a given PSI and hold that PSI over the course of the day. Honeywell has a boiler control that has high and low set points and a sensitivity band to control within a smaller (+,-) differential range so there is less of a steam impulse. I set up a PSI meter that allowed the distillers to monitor the steam pressure and control the gate valves against their demand around the available PSI, this could be a simple low pressure steam gauge your plumber can add to the steam line.
