When cleaning 7 barrel tanks, how much PBW solution and Star San are you having to use to conduct your CIP and sanitizing? For example, are you using a half barrel amount of PBW solution to CIP a 7 barrel tank and half barrel of Star San for sanitizing? Would that amount be too much or too little?

Thanks!

...refer to the manufacturer's website. MSDS available there as well.

I think the OP means how many gallons of solution are you making to clean a 7 BBL tank, not the dosing for 7 BBL of solution.

I usually make about a barrel and a half of cleaning solution and considerably more sanitizer, enough to hit all of the various sampling ports, etc. that the CIP ball can't hit, but that will depend on your tank.

half a bbl is what I use, on an 8 bbl fv

I use as little as possible without causing the pump to cavitate. My FVs are 40HLs and I use about half a hectoliter which is about 17% less than half a barrel. The mechanical action of the liquid coming down the walls is what cleans, much more so than the liquid itself sitting at the bottom of the tanks, consequently you want to have as little liquid sitting at the bottom, haven't you noticed that sometimes the bottom of the tank where the cleaning solution sits doesn't get clean (especially in the brew kettle)? In an 8BBL FV I would guess that half a barrel is more than you need. Try reducing the amount of solution until your pump cavitates and then increase it a little from there and you'll have your optimum amount. Optimum not only because you'll be using less chemical and saving money but more so because more of the tank will be exposed to the mechanical cleaning action of the moving liquid.

This is very good advice, especially for the primary cleaning cycle.

Agree with previous post about using as little as it takes to do the job. I have 7 BBL conicals and I mix 5 gallons of solution (caustic or sanitizer). I am using a total of about 15 feet of 1.5" hose in and out of the pump and never have had an issue. If you have to use a lot of hose you may need to increase by a gallon or two. The only time I ever run into issues with this is if the caustic cycle foams a lot due to a lot of crud on the tank walls. If I hear the pump start to cavitate I just stop and add a few more gallons and restart. This has only ever happened a couple of times though...

A half barrel in a 7 BBL tank is WAY more than you need. You'll probably get a nice fruit basket at the end of the year from your chemical supplier if you use that much every time!

+1 on as little as possible. I've used 7.5 gallons of caustic on a 30 bbl conical with no issues and same cleaning results as a full bbl of solution. I would recommend a pre wash for all cips. Fill your ferm with 5-10 gallons hot water and about 1/4-1/8th the amount of cleaner you'd use for your normal cleaning cycle. Run that for 10 minutes, drain and quick rinse, then your normal cip cleaning cycle. This really helps with reducing soil load on your cleaning solution and results in cleaner ferms, especially with high krausening yeast strains. Plus it saves you cleaning solution if you are regularly having to run two cycles to remove protein (which I have experienced). Good luck and cheers!
