### Open System Chiller Operation

Thank you so much Alex, you've been kind.

I got a lot of useful info, thanks.

Ps: congratulations on yesterday's victory, Ukraine played an incredible match

### Open System Chiller Operation

Alex thank you so much for your response and for the explanation.

I should have studied more physics in school, you just made me a really happy man

I forgot to mention in my previous post a "little detail", I'll be distilling with a single pass through a 4 plates column, so once the water leaves the condenser will go to the dephlegmator and that will Increase for sure temperature, but according to you calculations even if the final temp of water was 70C after leave the dephlegmator 600 liters/water x hour will be still ok, right?

Thanks!

### Open System Chiller Operation

Hi,

I'm in the process to start a micro-distillery in a rural area in Sicily, south of Italy.

I asked t an engineer to calculate the size of a similar system, but the power of the chiller and the dimensions of the tanks are much bigger compared with the numbers I'm reading here, 3 times bigger.

Could someone take a look?

I'll use a 600l (150 gallons) still.

The numbers I got from the still manufactured are the following:

Condenser water in: 20C /68F

Condenser water out: 70C / 158F

1500 liters/ 398 gallons per hour of recirculated water on the condenser

Considering that we'll distill twice a day during harvesting season I should consider 16 hours of use per day.

398*16= 6300 gallons of HOT WATER to cool EVERY DAY

what we're missing?

Thanks!

This is the basic design of my system.  Comments welcome.

My equipment is similar to Golden Beaver.

Having a process engineer at the local university design and build the control panel.  This is to run a 300 gal stripping still and 150 gallon finishing still at the same time.  Chiller is 6 ton.  Water tanks are 1600 Gallons.  Mash chilling is a separate process that will not run with distilling.  It is a tube-in-tube heat exchanger.  Today we are pumping a glycol water mixture through the mash chiller and we have to watch it as it exceeds the capacity of the chiller and can overheat the glycol and shut down the chiller.  We believe 1600 gallons of 55 degree water will get the job done for a 300 gallon mash (actually about 380 gallon as the manufacturer over-sizes his stuff).

That is the idea here... keep the chilled water at 50-55 degrees at all times.  The hot water tank is stainless, the cold water tank is poly and insulated.  The process dumps the output process water (warm/hot) into the stainless, and the system uses it as input water to the chilled water tank as needed.  If running out of water from the hot water tank, the system will inject city water into the loop.

Not using the chiller pump in this design for anything other than pumping glycol through the heat exchange.

### Propane fired Boiler or combustion options in rural areas

If you want very cheap green energy, good options are waste fryer oil burners.

I have 4 of them in my distillery for direct flame heating stills, and steam and hot water production. About to install 2 more.

Used engine oil also works in these burners, it is not so green but maintenance is easier.

With the waste oil burners you need a boiler that has a firebox that is easy to clean out, the waste motor oil makes a bit of white ash and the veg oil eventually causes a crusty build-up on the heating surface.

My electricity bills are very small.

Got it.

Thanks Pete.

Thank you Adam, all clear now.

What will you make at the distillery? If you will make grappa or fruit brandy there is a large advantage to a bain marie still.

Hi Andy, we'll produce grappa but not as a main product.

We'll start producing a Gin with local botanicals (Sicily produce if not the best one of the best citrus fruits in the world), but our flagship product will be fresh juice sugarcane Rum.

We use propane as our fuel source, too.

Recommend, steam jacketed and low-pressure boiler.

Thank you so much for the advise.

What I'd like to understand is why LOW PRESSURE; safety? performance?

### Steam boiler specifics

Hi from Italy,

We're in the process to open a small artisan distillery in Sicily, Italy.

After considering all our possibilities we decided to use propane to fired our still, we're in a rural area so natural gas wasn't an option, electricity is too expensive.
We haven't purchased our still yet and we have 2 possible solutions:

1. Oil Baine Marie pot still heated by a propane burner

2. Steam jacketed pot still fired by a propane steam boiler.

My question is regarding the steam boiler, it MUST be a LOW-PRESSURE steam boiler?

Thanks

### Propane fired Boiler or combustion options in rural areas

On 4/18/2021 at 7:58 PM, navenjohnson said:

We are working on a project in a rural area and are exploring options for combustion/ steam production for a 1000 gal mash tun/ fermenter/ stripper sized facility. We are planning on cooling using a deep-pond with a coil in it for heat exchange. Would also like to utilize some wind, solar and heat recapture to make the facility as green as possible.

Forefront questions:

Is propane the best option?

What other combustion methods are clean and cost efficient?

Who has done this before and has some insight on building such a facility?

Hello from Italy,

we're in a similar situation than navenjohnson and after consider all our options we decided to proceed with a propane fired steam boiler for our future 150 gallons still.

my question is, it must be a LOW PRESSURE steam boiler?

Thanks!
