  1. Converting Tote to Stripping Still

    Silk City, Are you saying you are using a glycol chiller @ -20F to condense the product?
  2. Converting Tote to Stripping Still

    Boiler feed only needs to be softened for the boiler to operate.
  3. Converting Tote to Stripping Still

    The company I represent has a boiler line that is "clean" non ferrous. You inject steam made from city water and the trickle that remains goes down the drain. what HP boiler would you need?
  4. Used dairy equipment

    You'd be better off putting a flow control on the chiller exit between it and the tank. One reason, you may damage the jacket itself- what is the rating in psi of the jacket. if it is only 15 psig, then you need to install a three way valve to bypass most of the glycol flow and a "flow setter" of you have multiple feeds off the process pump. How large is the chiller= tons of refrigeration or the flow? and the pump? Is your feed piping 2"?
  5. waste heat

    There are many ways, but this one is a no-brainer for Northern climates, pays for the aircooler in the first year - no refrigeration all winter!! In this setup, anything less than 30F is stored cooling to the reservoir, saving 10 HP of chiller run time all winter. I have a hybrid cooler that adds evaporative water to bring down ambient cooling, allowing running still, fermenters and mash cooler for all but a few months in summer.
  6. Electric Boiler

    Devil's in the details (like sizing HLT and trim cooler for excess heat)- a lot has to be known to accurately price out a complete system, but like you say, it's good to know what's out there for the future! In your example, it would seriously reduce boiler size ( I have those to supply as well). In your example, we can do this with current technology and swap out refrigerants when the new refrigerant is available- just in case someone doesn't want to wait:)
  7. Hello from Massachusetts!

    Well, he was smaller than the Dachshund when I picked him up, and now the Dachs can walk underneath him! Those needle teeth are a menace, too (my vet just laughed about that). He's a bit of a baby, tho- was scared at the sound of a bullfrog in the watergarden. Talk soon!
  8. Geothermal cooling

    3D has it right there. I've seen it where initial use was for geo piped grid, but when the distiller added on capacity, he needed to add the chiller anyway rather than the cost of much more pipe that could only get him near 55F- he ran out of field, too.
  9. Electric Boiler

    In a nutshell, I went to a meeting about a large heat recovery project which at present the refrigerant used will allow near 170F on the water side used for heating a building to replace a hot water boiler. The compressor manufacturer is now testing a refrigerant that will allow 190F water to be supplied. Testing is progressing to where the refrigerant will get the OK by next year to be used. The chiller used for this would look like a typical water cooled modular chiller, the chilled water side would be used for the distillery equipment cooling loop and the hot water side would be used for the hot water. In the case where heating water is not needed, we would use an additional outdoor aircooler to reject heat not needed. The chiller itself would be higher in HP but the efficiency of the refrigeration cycle is higher than either steam or direct electric heat, so initial cost would be greater for the heat recovery system, but overall consumption would be less and paybacks are usually calculated to be five years or less. The only way we can reclaim hot water off the chiller directly at present is to use a hot refrigerant to water plate exchanger, which can be used with todays chillers as an option. If you or anyone else is considering a design around heat recovery to seriously reduce the size of boiler or replacement to heat reclaim hot water, I can budget fairly closely with your distillery designer for a long term project or a heat recovery add-on to your present system. Contact me directly if you would like to be placed on a list for future notifications of heat recovery options.

    JJ, i used to call on clients in Erie when I lived in BFLO, loved those snowy days heading downhill on I90 watching trucks slide off the hwy! If you need any additional cooling or add ons, give me a shout. Mike
  11. Electric Boiler

    Hedge, nicely put. I am hoping to create a path to less op cost for either by being able to heat water up to 190F (now max out at about 160F) with a heat recovery chiller.
  12. Distillery Consultant / trace ownership?

    LOL Bart, when I was studying aero-engrg in college, all we had was slide rules and the first hand calculator which seriously curbed my happy hour Fridays! I swear the Prof was a sadist in a past life. Good luck and if you need cooling equipment budgets, give me a shout- I can do the same (at will). Regards, Mike
  13. Electric Boiler

    Next year, I will have a chiller to make 190F water with a new refrigerant coming on board. Right now, I can offer a chiller with a tap to plumb to a heat exchanger/water heater. These are concepts to either replace or reduce the size of a boiler whether gas or electric.

    Good luck to you Larry/Joe!
