How to bottle directly from conical fermenter without air pocket issues?

[BandonBrewingCo]

I have a bottling wand connected to my racking arm via a bit of silicon tubing.

Lid on fermenter cracked open.

Open valve on racking arm but no flow. Take away bottling wand and lots of flow. Confirm no blockage in wand. There's some sort of air issue and I think of the little hole in the spigot on a bottling bucket so poke a tiny hole in the tube and voila, bottling tube and wand are flowing.

How can I avoid having to poke a hole in my tubing? The hole introduced a metric **** ton of bubbles and probably oxidated my beer.

I'd love to not have to use a bottling bucket

Can you add a bit of pressure in the conical to give the bubble a shove?

Ya I think I could hook up a soda stream bottle somehow. But what's creating the issue in the first place?

Me no physics good

Maybe, instead of adding pressure, you can pre-fill the tube and filler with water, and thus avoid the bubble blockage. The first ounce or three can be discarded and transfer can proceed.

Ain't no shame in holding on to lodo, as long as you make room for other things too

fwiw, I forgot to purge my 2-foot transfer line, so no LODO purity for this batch - dang!

Anyone have any ideas on how to replicate the vent hole in bottling bucket taps/spiggots on a stainless conical racking arm?

@doug293cz sorry to @ you directly but if I'm not mistaken you're a man of physics and engineering?

Siphon or spigot? Maybe post a picture of your setup? Is it similar to sibelman's?

It's the little hole in the middle

Need to replicate that same effect on this hose Barb outlet

Or figure out a workaround so it's not needed.

When I tried to bottle directly from here using silicon tubing and a bottling wand I couldn't get any flow without cutting a hole in the tubing which introduced a ton of oxygen and was generally messy and unsanitary.

Would filling the tubing and wand with starsan first get the flow going? Without the bottle wand it flowed no problem, as did the bottle wand without the conical.

Anyway, poking the hole proved there wasn't any blockage that wasn't air.

And the lid was cracked open.

Had zero issues today. Was told the issue above may be because of the Bernoulli Principle (I don't know either so don't ask).
