(Apologies in advance because this thread makes reference to something posted a couple of weeks ago … thought this was a compelling enough possibility to repost as the central topic)
For those that ferment in Cornelius kegs and want to transfer from ferm to serv in a way that leaves behind the majority of sediment, and if not wanting to use a floating dip tube and if hesitant to cut a dip tube, how about the idea of a Cornelius keg dip tube final liquid level / sediment exclusion foot that could be installed or removed in seconds allowing any keg to be used as a fermenter and then back to a server? What if modifying dip tubes was unnecessary with simple alternatives?
Most folks will be familiar with a racking cane, so, given the principle of the “sediment exclusion foot” on a racking cane how about something like the following
Those images are just for illustration … a racking cane foot probably wouldn’t reliably stay on a dip tube and probably one would want something a little taller ... but what could do the job? Have done searches for “stainless steel vial”, “miniature test tube”, “stainless steel pipe cap”, “stainless steel lug nut”, etcetera. I like the idea of stainless steel and possibly but preferentially not glass. Some of these are looking possibly interesting
This is a "vial" with a screw top intended allow one to wear a small quantity of something in a neckless. The deal breaker here is the clear portion is plastic
This is the bottom of a miniature glass screw top bottle so in this case one would have to be cutting off the top
Similar idea, requires some glass cutting? Or would the tube be a good fit down into the neck? So here, one would be committing to drawing down to only the top of the height of the bottle so not customizable
This is looking more interesting. These are miniature flasks intending to allow one to wear a small amount of liquid on a neckless. And so, these are food-grade stainless steel and intended for consumption related use
Looking interesting here. A question would be, would the dip tube fit down into the neck? If so, that makes the job so much easier. So in this case, if the tube would fit into the vessel, one could estimate how low they want to draw liquid from, how much liquid to sacrifice in the interest of eliminating sediment, and at that height drill three holes around the perimeter.
Now, a couple of constraints are that something like that isyou're just going to have to expect/hope that the bottom of the dip tube sits crooked enough against the bottom of the vessel to allow liquid to pass into the tube, and you're going to have to have a little bit of luck that there is space enough between the bottom of the keg and the bottom of the tube to allow this to fit into that space. I guess in the first case if the bottom of the tube was sitting too closely to the bottom of this "foot" could one throw in a few spare "O rings" to create some gaps?
There could be other possibilities like food-grade rubber hose that was large enough to fit completely freely over the dip tube and not seal against the bottom of the keg but to fit well enough to keep out most sediment, and ideas like hoses inside hoses for the same effect. I did try a dip tube in an upside-down keg post but the fit was so snug it would simply halt flow. If one wanted to go with plastic hose I guess one could install two gas dip tubes and have the "OUT" one connect to a fixed length piece of tubing that was hanging an exact distance above the bottom. But that's back to the concerns of floating tubes bending or leaching or curling and kinking and not thrilled about rubber/plastic in fermenting. Finally, if one could do fine stainless steel fabrication a small "J" shaped foot could be constructed that would push onto the end of a dip tube and causing flow to be turned 180 degrees back up the tube to the point where one wanted the final liquid level to be and it would function like a pond stand-pipe drain.
Maybe some of you have already perfected the Cornelius keg dip tube final liquid level / sediment exclusion foot? Appreciate any feedback, thanks -
