Any easy way to clean glycol chilled keg fermenter?

[mats_ceder]

Hello, I've been lurkin' around HBT for two years or something but this actually is my first post here. I'm a swedish homebrewer and I have been brewing for some time now, currently using a Braumeister 20L and fermenting in plastic buckets inside i controlled refridgerator. My plan is to build eHERMS rig, almost like www.theelectricbrewe.com, for 20liter/5gallon batches, and while I'm at it I thought that I might aswell build me a set of glycol chilled fermenters similar to this one posted in BYO a couple of years ago https://byo.com/stories/issue/item/1877-build-your-own-glycol-fermenter

Before I start doing things I really like to think things through so I don't have to do things more than one time. My concern when I look at that BYO article is that I don't really understand how i would drain the kegs after cleaning them? Or how exactly they think that they should be cleaned. I'm thinkin' about cutting the top and add a corny-top or a custom top to the keg so that I can reach in to the keg and also have a CIP sprayball attached inside. Would the easiest way be to make a hole in the bottom of the keg and install a valve? I don' really care for reusing the yeast but I do want to get the water/cleaning product out somehow.

How would you do it? Anyone ever make one of these glycol chilled fermenters from old kegs and have any experience?

Thank you, hope my english isn't to bad

The process is no different than any other Sanke Keg washing project. Lot's of guys do it.
The key is to start with a really clean keg, and then wash them out immediately after fermentation.
Personally I ferment in a small refrigerator using an STS 1000 controller, then wash with a small pressure washer set up with a 90 deg tip to hit the insides. In order to let it drain while washing, and to easily get all the areas efficiently, I use a board with wheels on it to hold the keg on it's side so that it can be easily rotated while spraying.
That system may or may not work for you.
Others use cleaners and CIP balls with the keg upside-down on a keg washer.
Personally I would not cut a keg to add a large lid, and I'm an accomplished welder with my own equipment. I just wouldn't do it.
