    Buried pipe for condenser water

    in Beginners

    Posted

    I think the one client I had did look into the ground piping set up, but when he added up the cost of pipe and labor, he figured the underground cistern (ribbed poly type) would be a better way for him. He is located close to the boot heel in MO, so he figures he can have the ground keep the cistern between 55 and 60F until summer loads make him switch over to chiller.

    You might do the calculations on the material for both and see how it comes out, tho.

    I am waiting for results for an underground tank set up with an air cooled glycooler I recently supplied.

    It can be done both ways but the issue is more with the mash cooling where the demand is quite concentrated, so you still have to add a chiller which I will do for the distiller mentioned for summer duty, it might just be a bit smaller.

    You still will have to install a reservoir tank - especially if you're doing mash cooling-

    There won't be enough mass of fluid in the tubing without it.

    Contact me if you would like me to send you more info on the glycooler.

    cooling mash with ground water

    The type tube in tube exchanger I use, I generally use 30 GPM of recirculated chilled water for a 500 gal mash and it gets it done in less than 2 hrs.

    Devils in the details as far as the heat exchanger design goes.

    As far as the way I see it, your tank size will depend on how much makeup you are drawing from the well to fill the tank.

    About as much as I can offer, hope it helps.

    Mash in fermenter?

    in Equipment

    I'll second what Lenny is talking about. We operate on a 15 barrel system (Mash Tun, HLT, and Fermenters) but our still can only handle a charge of 150ish gallons. That means we are doing 1.5 days or 3 days of stripping runs to get through our wash. Now that's not bad, but what you are talking about seems like a very long time between strip 1 and strip 9/10. Our dream is to get a 600 gallon stripping still so that we can get around this bottle neck and make more product.

    As for your process of cycling and cooling, how are you going to get the grain out of there and not clog your H.E. ? What is the plan for that? I've seen some creative set-ups.

    I use a shell and tube exchanger from Trident which won't clog. I generally recirculate the mash to and from the mash tun with one of my cooling systems providing cooling water. Depending on cooling time required, a 5 or larger chiller will chill the mash.

    Alternatives to Glycol Chill Filtering

    in Technique

    I supplied a glycol/air cooler for winter operation in MO distillery. He is putting a cistern underground filled with glycol /water solution.

    Ground temp holds cistern at nearly 55F and the air does the rest of the work.

    With enough data from winter operation, he plans to be able to buy a smaller chiller than the 10 HP one he would normally need.

    I have another job waiting shipment where the customer is using the old farm milkhouse tank and well for mash cooling and if necessary, is going to run a heat exchanger and glycol loop over for any additional cooling if he runs short.

    That all depends how long you have timewise to do the cold filtering.

    You are going to lose 1/2 the capacity (HP) to get the glycol cold enough for the filtration.

    I have never sold a chiller less that 3 HP for cold filtering, but realistically even if you took a large amount of coil inside a large freezer, I bet it would cost you thousands just for the metal.

    I have some smaller units coming out over the winter, but I doubt any would be much less than $3 or 4K.

    I can get a 115/1/60 small chiller out of Buffalo, but that is over $4K.

    If I find anything smaller, I'll post it.

    Used ones I have are 3 HP either 230/3/60 or 460/3/60.

    The Canadien outfit I work with in Toronto could ship you one new, my price for a 1 1/2 HP chiller that would do the trick would be $7,000, but that includes the duty to USA, so I assume it would be a bit less.

    Looks like you will need to look for something that size on your side of the border that is 50Hz.

    An update. We will also be equiping the iStill One with our new oversized SPP. Well, on demand, that is. When you order the SPP packed cleaning sections on the iStill One, you will get more plates. Suited for vodka making, not for whiskey or brandy making. For that you need our standard ceramic column packing.

    A bit more on cooling water usage as well. A 1,000 liter (260 gallon) run only asks for around 1,500 liters (390 gallon) of cooling water.

    How long a period is the cooling required, assuming the input water at 50F?
