  • 1.  Meters for phase change between beer and yeast etc

    Posted 10-29-2024 17:59
    Hi all,

    Looking for a solution to monitor phase change between yeast and beer, specifically in cropping yeast from a remote outside FV to inside our building.
    We are looking at conductivity meters to monitor beer/water/chemical cleaning phase changes, but I don't think these will work for Yeast to Beer.

    Has anyone used Turbidity sensors from Seli in Germany?
    We are looking at either Type STS 15 or Type STS 06.

    We have quite a long run from the FV's to the swing panel in the brewery and are trying to limit the need for people outside during as many processes as possible.  We have a minimum of a 45ish gallons in piping and want to limit beer loss when either dropping or cropping yeast from these tanks.

    Hi Madison,

    It's not quite the same thing you all are looking at, but I used to work at a large regional brewery, and we used density meters for more accurate yeast pitching tank-to-tank. While these are for yeast harvesting and pitching, I think they could be reconfigured or used as-is in such a way as to let you know when the yeast slurry has changed over to beer.

    At the time, we used an Endress+Hauser Promass83 Coriolis flow meter (this seems to be the more up-to-date version); the brewery has upgraded now to the Aber Perfect Pitch, which still uses the E+H Coriolis flow meter as a part of it.

    I'm not familliar with Seli sensors.  Optek makes sensors for this application, including the AS56-N and AS16-VB-N, seen here:

    https://www.optek.com/en/brewery/yeast-management.asp

    I have not used these sensors for this purpose, but I have been happy with other Optek sensors for performance, reliability and service.

    We looked at some turbidity meters to be used inline before our keg filling machine to ensure no yeast from our centrifuged beers made it to the packaged product.  They would likely work for your application.  I believe the brands we looked at were:

    Metler Toledo, Endress and Hauser and Anderson-Negele. 
    There was another German brand that I can't recall the name of, but I think it was slightly more competitive in price and also could control a shutoff valve directly without the need for an external PLC. 

    Hope that helps!

    Madison,

     

    Anderson Negele has a Turbidity sensor for phase separation.

    Hi Madison,

    I have applied a Canongate Densicheck TX instrument for similar applications.

    Mostly beer water interfaces.

    It provides a cost effective method to monitor for an interface than a mass flow meter.

    It comes in a variety of in line connections but I would recommend the varivent connections as the best for cip ability.

    I have included a data sheet for reference, I do not have a Canongate contact though.

    Have a fun weekend.
