CIP/SIP of BBT under pressure
Anybody care to share their SOP for this? We just got a new chem from Loeffler to try this out and they gave us a few parameters, just trying to find some industry best practices. Thanks!

Birko has a white paper called “Reducing Dissolved Oxygen in Beer” that outlines the procedure when using acid based chems. I have a copy if anyone is interested. Alternatively, it may still be on their website.
Edit: send email address via dm to receive the paper.

What equipment are you using for CIP? Having a cart vs not will make a difference

We do have a cart

Bare bones version:
- Hook up CIP cart to brite tank
- Gently backflush CO2 from brite to purge your hoses of O2
- Rinse brite with hot water to remove any solids and preheat to desired temp
- Fill reservoir with chemical
- Start pump, open outlet valve, and pump all chemical into brite
- When reservoir is empty, turn off pump, close outlet, and rearrange valves into a CIP loop
- Run CIP cycle
- Drain chemical and rinse
Repeat 4-7 for sanitizer.
Note that everything will be under pressure so you need to be quick and deliberate with opening and closing valves

Also make sure your pump is turned up all the way if you have a VFD before you open the outlet valve. If you don’t, the pressure from the tank will overpower the pump and back flow through your reservoir. A brewer at my first brewery got second degree burns because of this…

Rinsing as much as you can just to get as much stuff out of the tank as possible. Bring the pressure down below 5-10psi, assuming your pressure is higher from packaging before going to CIP. Hopefully you can attach a triclamp to your carbstone to push chem solution through it. Would use a 1/2 barrel brink as a reservoir for everything. I would get paranoid that my pump was introducing oxygen so I would do a short purge after and bring back up to pressure.

If it was the same brand I'd just rinse with 180F hot liquor. Acid cycle if going from an IPA to lager. Fully break down and caustic after 3 turns.

180f right into a cold brite? That's rough on your tank.

Just be sure to leave to glycol running!

We use a chemical acid called Octosan (no idea what the actual chemical is). It's sold as a CIP/SIP CO2 Pressure Cleaner for pressure Brite tanks.
2% dilution at 65°C. We drop the tank to 10psi and hot rinse to bring temperature above 60°C and rinse through all ports using a custom made quad manifold attached to our CIP arm. Minimum 30 minutes contact time with the chemical through all ports. Than an 85°C hot rinse, neutralizes chemical. Drain the tank the blow down and do a 20 minute purge at 30lpm.
The tank is always kept between 10 to 15 psi during the cleaning process we find our sprayballs will struggle at 1bar or more internal pressure within the tanks.

At the last brewery I worked at we did this. Nitric/phosphoric pushed into an already spinning tank with ~60C water under like 3-5psi at 2%. Spin for 30-60m, depends on preference. Push out with positive pressure and rinse thoroughly.
It’s a bit sketch the first few times, but once you get the groove of it, it’s super convenient.

I’m a pub brewer. I will either give a couple good outs of said tank and transfer right on in. Maybe sani rinse every few turns.
Again pub brewer.

Don’t use caustic.
