  1. I am worried that this might be a remnant of the manufacturing process which might contaminate the product, so wanted to clean it beforehand.
  2. Thanks. What concentration of citric acid should I try ?
  3. While testing our still we boiled some water from the water softener. Now there are black stains on the inside of the still. This did not happen earlier when using hard water. Has anyone else experienced this and any tips on how to clean this off ?
  4. What gaskets do you have in your camlock with high proof alcohol ? Most of the camlock fittings I am looking at seem to have Buna-N gaskets
  5. What are people using for connecting hoses/pumps to tanks ? We are using tri-clamps but there are cases where we have to move the pumps between tanks. Getting the PTFE gaskets to seal is not as simple as I thought, and I don't relish the thought of doing it several times a day. High proof alcohol, so I don't want to use other elastomers like BUNA-N/Silicone. One option I was looking at was these quick disconnects. Made of SS. But the O ring inside is probably rubber. https://www.morebeer.com/products/female-stainless-steel-quick-disconnect-wbarb.html?site_id=9
  6. Michael, Do you have these G70 barb fittings in 3/4 in stock ?
  7. Do you know where I can buy the 3/4" fittings for the pump ?
  8. Paul, I already bought two of the pumps from you with 5/8. So can I purchase the 3/4 for them ? I can't find the fittings on your web-site.
  9. What are the input/output connections on G70 explosion proof pump ? TCW has it listed as 3/4" barb, while distillery-equipment has them as 3/8" barb. The manual says 3/8-1/2".
  10. Lenny, I was looking at NDP-15 pumps. Either NDP-15BPT or NDP-15FPT. Both are PP body with Teflon seals for about $400. The difference is flat vs ball valves. They'll do about 13.5 gpm .
  11. Michael, You make a valid point. Their PP pump is not groundable, so can't use it with high proof. But wondering if it still might be okay with low wines (20% ABV). And use G70 to move high proof alcohol (55-70%).
  12. I am wondering if it is okay to use polypropylene body for spirits transfer pump. People have recommended Flojet G70 pump in the past which is polypropylene. I have been looking at Yamada pumps, and if I get polypropylene body with Teflon elastomers, I can get a 13.5 gpm pump for the same price as Flojet G70.
  13. Filed on Mar 6 Approved on Jul 29th 145 Days. Seemed to be stuck, but David Dunbar managed to get it moving Now trying to beat Bill's challenge and score a dinner
  14. Hi, I am looking for recommendations for a customs/landing agent/freight forwarder in California.
  15. Do you have a source for the Teflon gaskets. I have been looking online but can't find any for manways
  16. Paul, So your recommendation would be silicone over EPDM for stills. I looked for manway gaskets on your website but couldn't find any
  17. Hi, I wanted to know what gaskets people are using for stills and for tanks storing high proof alcohol (Vatting tanks, spirits receivers) ? EPDM or Silicone ? We are planning to use PTFE for TC fittings, but can't find any PTFE for manway gaskets.
  18. California Building Code 2016 : Table 509 requires separate boiler room if you are running a high pressure boiler (above 15 psi) and above 10 HP (about 330,000 BTU/hr). I am assuming you are planning to use a low pressure steam boiler, so you shouldn't need a separate boiler room. Unless your city has more stringent requirements above and beyond the California code. Ask a local boiler company.
  19. Wanted to know if anyone had to anchor barrel racks for seismic reasons. We are looking to get the 7" 4 barrel racks from Country Connection and stack them 4 high to stay under the high pile storage. One architect we are considering told us that these will need to be anchored seismically because they exceed 5' in height and 400 lbs in weight. Has anyone else run into this issue. Since they sit on top of each other, Not sure how they'd be anchored. Maybe strap adjacent racks together ?
  20. Thanks for the pointer. I looked at California Fire Codes 2013, and Chapter 4 is titled : Emergency Planning and Preparedness. So I guess that is the starting point on what needs to happen.
  21. Does any one know of resources for emergency procedures for spill control and fire in a distillery ? Or is this something a FPE can put together ?
  22. You can take a look at MQ-3 sensor which will detect down to 125 PPM. The LEL for alcohol is 3% or 30,000 PPM. Typically you'll start the exhaust fan at 25% of LEL which is 75,000 PPM. You could probably build one with Arduino for under $50. But for something this critical, do you really want to risk a homebrew design ? https://www.sparkfun.com/products/8880
  23. I think your name should be changed to Amazing Dave. Very deep and informative. The part is liked the best is "I'll not make a long comment here" So the takeaway is : When withdrawing from bond (for tax purposes) like bottling, you must have an accurate scale per TTB guidelines For other tanks, you can get away with sight glasses - low wine receiver : filled from wash still, feeds the spirits still - feints receiver : filled from spirits still, feeds the next batch of spirits still - intermediate spirits receiver : filled from spirits still, feeds the spirits receiver - spirits receiver : filled from intermediate spirits receiver, fills the barrels
  24. Thanks for the replies, it seems like scales are the way to go. I'll definitely reach out to Fred at Prime Scale. It seems everyone is moving the tanks around. I was wondering how people with tanks bolted to the ground are using scales ?
