Some serious keg washing going on there. Looks like you are getting it under control.

Initially I made a single head keg washer but it took the whole day to wash and sanitise.
I usually wash 30 to 40 kegs when I run out of clean kegs.
Today was a first day I used double head and I am quite happy with it.

Definitely makes cleaning go faster.  I remember running a single and the feeling of overwhelming joy when I first got the 4 head installed at Ice Harbor.

Why copper? Why not PVC or CPVC if it's really hot liquid?

It is about 150F.
I did not think about CPVC.

I think your copper is better but damn that stuff is expensive these days.

Expensive. It depends how you look at it.
New Keg washer $15,000 to $20,000.
Homemade copper keg washer $150 - $200.

I did not priced SS keg washer but I figured if I rinse it after use copper will last me some time.

Hey, I like your double head washer.  It's funny that they can charge so much for the same thing that you just built.  If your's doesn't work out you could always try one of these http://breweryparts.com/index.php/fittings-and-valves/fittings-custom-amp-specialities/manifold.html (http://breweryparts.com/index.php/fittings-and-valves/fittings-custom-amp-specialities/manifold.html)  with a few valves and a few triclamp/hosebarb fittings you could build the same thing.  I've used a similar set-up and it worked well.  cheers, j

Title: Re: You wanted to have two head keg washer.
Post by: jaybeerman on November 22, 2011, 11:19:44 PM
steps are as follows
1. with all other valves closed and your drain line (the co2 line of the keg coupler) on the floor or in a drain, open the valve on the keg to relieve pressure and drain out the remaining beer
2. open valve for rinse water (hot works better) - that's water into manifold, out the hose to the keg coupler, through keg and out drain hose onto floor
3. close valve on keg, place drain hose into the cleaning agent (hot) holding container, turn on pump, open valve to flow cleaning agent into the manifold and into the keg, open valve on keg to allow flow but maintain pressure. run clean cycle
4. use co2 to push all cleaning agent out of keg and back into holding container
5. place drain hose back onto floor or drain, run rinse water cycle.
6. use co2 to push all rinse water from keg
7. set keg aside

Run all kegs through this set up, then swap sanitizer for cleaning agent and run a sani cycle through all the kegs. Push all sani out with co2 and pressurize the keg to storage pressure.  Done (go home and cry, wonder why you decided to be a brewer.  Remember that you get to brew tomorrow, smile and go to sleep)

This manual is very helpful.
It is Specific Mechanical single head washer.

Concept is the same for dual head washer.

+1 except I use compressed air to push rinse water and cleanser water and co2 only for sanitizer.

The nice thing about the $15K washers is you put your keg(s) on the cleaner and push a button and come back and they are clean. Cheaper ones available are semi-manual. I have my eye on a premier stainless keg washer that is fully automatic though. But $15K is a huge chunk to cough up.

$15k is a lot when you are working for $3.35 an hour like most business owners do.  :o

TM  just needs a hot caustic tank to clean them

Seems to me that some solenoid valves, dedicated tanks for all liquids and a programmed PLC would get you automation. You would need some SSR's on the outputs, but all of this stuff can be had pretty cheaply these days.

The procedure described below sounds like nothing more than timed, sequential steps and that's not hard to program either.

We have been working on a semi automated keg cleaner. It is just back logged on everything else we have going on.
Title: Re: You wanted to have two head keg washer.
Post by: bo on November 30, 2011, 01:29:59 PM
I have to imagine that you use a lot of non reusable rinse water for this. Does the final rinse have to completely fill the keg? I wouldn't think the first one would need to be.
Title: Re: You wanted to have two head keg washer.
Post by: majorvices on November 30, 2011, 02:16:26 PM
No, it's not even close to filling the keg. We do a timed hot rinse under compressed air, similar to a pressure wash.
Title: Re: You wanted to have two head keg washer.
Post by: bo on November 30, 2011, 02:23:34 PM
How can you be sure the rinse is distributed throughout the keg? I can see if it's upside down it would hit the bottom ( now on top) and cascade down the sides, I've never really looked that close at a spear. I guess the CO2 comes in right below the connector.
Title: Re: You wanted to have two head keg washer.
Post by: majorvices on November 30, 2011, 02:58:37 PM
It's just a process of time and pressure. Ii believe the kegs are designed to distribute the cascade. I feel confident that the rinse, clean and sani process works. We pull the spears out of one every couple of weeks to double check.

I use brewhouse for that.
PBW at 150F is doing a pretty good job.

I agree that it is pretty simple process.

As Major said there is only 24 hours in the day.
There is a plenty of work to keep business running.

Saw Oso's keg washer it does one at a time but will wash and fill at the same time. I think it costs about 6k new, chhaa ching! But it has its on holding tank for hot caustic and totally programable, bet one could be built for alot less. It takes less than 3 minutes per stage.

+1 to the manifold reference...Used that style of setup for almost a year until a used mini king was available for a fair price.  Be sure to have an air compressor so you aren't using CO2 to clear your caustic/acid/etc.  Then Purge with CO2 and pressurize.  Plus "flushing" with CO2 may likely crystalize your caustic making it useless.
