Fermentation Test

Recommended Posts

Couldn't find any reference in the manual about what "Ft" being shown in the droid window meant, but apparently it's a "Fermentation Test".   Thought the thing had gone bad already. Clever thing this droid.  EDIT - Found it, on page 9. Easy to miss though.

Does anyone know how the droid actually does this?  There does not seem to be any sensors or the like inside the droid tub itself.  How on earth does it detect propagation, fermentation, EOF etc?

Am I asking too much here....is this wildly proprietary information? 

Just pure curiosity on my part.

It uses the temperature sensors to do the fermentation tests. There is an algorithm that BrewArt uses to test for fermentation which determines when it starts and finishes depending on the temperature change during the test.

They describe it as an algorithm (and proprietary). I suspect that as the app can detect the temperature to 0.1 deg C, and the fact that the droid knows the ambient temperature, they are using an algorithm to check for exothermic <<-- big word there -- reactions caused by the yeast making alcohol and CO2.

Well found, but the link doesn't work ? as presented. However if you go to here and put "Fermentation Coopers" (without the quotes) into the search criteria, tick the box that says "include abstract text" and search you will be presented with some results. If you select the 4th in the list (for me) application no. 2008217539, click on the application number and select Specification/e-register then click on download specification(AU-A1) it will provide the PDF file describing the process. There is a second document (AU-B2) that seems to be an update to (AU-A1) but I only glanced at it.

An interesting read.

Wow Pursya/Matt, I can't believe you guys found that.  You must have wayyyyy too much spare time.

But I am glad you did.  A very interesting read!   Thanks for doing the research.

Thanks MattS. Don't know why you can't post links in here.

Derren, I got the link off the JustBrewart site, all kudos to them.
