  1. Try the cheap ones. The pleated filters will more likely require a higher pressure to push the liquid through. When I use absolute filters it takes 3-5 Bar of pressure, you can not achieve this with vacuum. I have to polish filter with a pump separately and then later run the bottle filler with a cheap depth filter.
  2. Filtration can turn into a really big rabbit hole and so this is brief and general. there are depth filters (wound or spun fibers) and absolute membranes (like a really fine mesh screen). For bottling I use a 1 micron depth filter, it is high-flow and does not bog-down the filler. When I need a true polish I use a 0.45 micron absolute membrane filter. Only in extreme cases I will use a 0.20 micron absolute membrane and these are very expensive. If you paid less than $100 for that element it is not absolute. If you are truly seeing visible particles, (not haze) then either the filter is dirty on the clean-side, not seated properly with leakage around the element or it is coming post-filter from the bottles fill-spout or?
  3. The issue that is probably biting you is that these exceptions are ground transportation only, (sorry missed that detail earlier obviously you are on an island and thus more dependent on air freight)
  4. Yep, I applied to FedEx over 3 weeks ago to ship and have yet to receive any response which was supposed to be 5-8 business days (a week ago). USPS was 1/2 the price so go with them...
  5. Do what I did, take your shipment to your local post office with a gallon extra for donation to that branch, my packages are on the way... (to family, I'm not selling on-line)
  6. The FDA has approved the WHO formula for production by DSP's. This is a liquid not a gel, so anyone making a gel formula that is not a registered compounding pharmacy is breaking federal law. As for the pricing, I'll let the karma police deal with them after this pandemic is over.
  7. Yes I spoke with a DOT representative who later followed up with an email to thank me for our discussion. They are basically trying to get the word out that the DOT has lifted shipping restrictions (flammable liquid) for hand sanitizer (btw, the USPS is now delivering hand sanitizer which is way cheaper than FedEx).
  8. A culinary boiler is another (probably less desirable) option, these are basically a steam fired water still. If the piping system is properly designed and the boiler chemistry correct, you should be able to get extremely high purity steam off a conventional fire tube (Scotch Marine) boiler. A steam generator like Miura & Clayton will not produce high quality steam, they are very efficient but high carry-over (low quality) is the trade-off. Other boiler designs with low surface area to BTU ratios will not perform as well as the Scotch Marine. Any boiler will spit out low quality steam if the load swings wildly. Separators & filters can help but proper distribution and condensate trapping are key. Another option if you are real paranoid is a super heater, but that is probably over-kill.
  9. Current TTB rules limit cocktails to approved container sizes which vary between 50 ml minion (smallest) to 1750 ml jug handle (largest) bottle. Larger sizes are not allowed at this time.

    Biomass boiler?

    embrapa is their ag research agency, I'm sure that's where I found that document. https://www.agencia.cnptia.embrapa.br/gestor/cana-de-acucar/arvore/CONTAG01_105_22122006154841.html Short answer is there should be plenty of biomass energy bagasse to fuel a boiler and distill the rum wash produced from said bagasse.

    Biomass boiler?

    If you research Cachaca production in Brazil you can get that information, it will be on Portuguese. It has been a long time since I came across it, but it had a lot details will look and see if I have a copy to share.
  12. Temperature is the wrong process variable to be controlling via automation. The boiling temperature of the wash changes as the alcohol is depleted. If you can’t afford the expense to control steam flow via a flow meter + pressure + temperature, then you are better off to control manually with a hand valve. Keep control simple. Automating a safety interlock is more important than trying to automate steam flow.
  13. would need more detail to make a better recommendation. I would install an automated shutoff valve that kills the steam flow if the temperature exiting your condenser gets above 40 Deg C. This is a safety protocol that every still should have. This valve should be in a fail-safe configuration (normally closed, air to open) so if you loose air pressure (or the condenser gets too hot) it will shut down the steam. I would skip the automatic valves and install 2 hand controlled valves in parallel, one large full pipe/port size (gate or ball ) for heat-up and a small globe with control markings so you can document the correct valve position for different spirit runs (search for "continuous blowdown valves"). Open the small valve to get the pipe & still jacket hot, only then open the big valve until you get the line arm warm then close the big valve. With experience you will be able to dial in how many turns open on that globe valve gets you the sweet spot on your still. The boiler burner cycling will effect the run, but there isn't much you can do about that other that oversizing the boiler to give the system more inertia or installing a 150 psi boiler and trim the pressure near the still. The body size of a control valve is somewhat irrelevant; it is the valve coefficient Cv that determines capacity. A boiler has to run 20% below the PRV setting which in this case is 12 psi max. At that low pressure, steam volume per pound is relatively large so your pipe size might need to be 4" or more. Sizing steam pipe is all about the line velocity, I'd size for 5000 ft/min. So a 2" pipe at 5000 is going to pass 457 lb/hr of steam at 12 psi boiler gauge pressure. That equals 13.2 BHP which isn't a very big boiler. Will undersized pipe still work? maybe but it will be loud and could damage the steam jackets. Automating steam flow in a meaningful way is going to require a flow meter & pressure transmitter so the automation can control based on energy flow into the still. That's probably over $15,000 in equipment. Likely the biggest overlooked issue on the steam side is air venting. Be sure to have vents high on your steam jackets in order to vent out the non-condensables (air). Air inside the jacket will act like a big blanket and shield your heating surfaces from the steam. Then you'll get a slow heat-up and everyone will go over to see what's wrong with the boiler when the problem is air inside your steam jacket. Don't get expensive automatic vents, just have a 1/4" ball valve piped 4' above the ground and extend the pipe to within a couple inches of the floor. Once you get the jackets up to pressure open these valves and let them blow for 10-20 seconds. If you have a slow heat up vent them again.
  14. Dave, was in DC yesterday so I'm slow responding, I have a triclamp on the end now so I'm just eliminating another connection. I have a straight pump connector for the discharge and will have to lengthen the discharge tube in order to mount the large valve on the side above the old quick connector. Skaalvenn, here's the packing list, you need to save the 4 check valves off the manifold exit and mount them directly onto the spout inlets, the rest of the birds-nest gets tossed, the 1/2 tubing is for the pump inlet and dip tube. I'm looking for a 2nd filler, what other fillers are you using? 2883N12 Barbed Precision Flow-Adjustment Valve for Food and Beverage, for 3/8" Tube ID 1 Each 2879N11 Food and Beverage Precision Flow-Adjustment Valve with Push-to-Connect Fitings for 1/8" ID and 1/4" OD Tube 4 Each 51735K26 High-Temperature/High-Purity Silicone Rubber Tubing Soft, 3/8" ID, 0.655" OD, 1 ft.
