Subject: HBD On The Move...

Greetings, Beerlings! Take me to your lager...

At long last, I've initiated the move of the HBD from its commercial
connection to a hosted solution. I will do my best to keep you abreast
of progress, but be aware that the HBD itself (the email list) may be
knocked out of commission while I wrangle the code to conform to its
new environment - I'll run both systems in parallel until either the
new server will run the scripts, or until the HBD coffers run dry.
Unfortunately, I'll have to whack the existing connection as I simply
cannot afford to run a deficit in the HBD treasury against my own
budget at this time. Hopefully, I'll be able to get the scripts
running under their new environment before that happens.

Alejandro, you may want to try throttling the flow of glycol to cool
more slowly.

Subject: Re: Problem controlling fermentation temperature

Alejandro is having trouble controlling his fermentation temperature in a
100 gallon conical, glycol jacketed fermentor. Alejandro is experiencing
substantial hysteresis in his temperatures relative to the controller
settings. I have no experience with such volumes, but it seems the community
could use a little more information before we can help.

My first thought is to reduce the differential from 3 degrees to 1 degree.
This would certainly reduce the hysteresis. It would help us to know where
the temperature probe is located, and I think it would also help to know the
temperature gradient within the fermentor from center to wall and top to
bottom.

It seems that minimizing the differential on the controller and optimizing
the placement of the probe would be most straightforward approach to this.
Surely the small commercial brewers have a standard workaround to this common
issue.

Subject: Problem Controlling Fermentation Temp

Alejandro

As I see it you have multiple problems. First your 3 degrees differential is

too high, and let's assume your temp probe is in the middle of the

fermenter. The fermenting wort close to the walls cools fast unlike the

middle. Even when the ferment is rapid it will overshoot your required temp.

Some thoughts for you.

1. Reduce your differential say to 1 degree.

2. Restrict the output of your glycol pump to slow the cooling rate.

Reducing the differential will mean your cooling pump will run more often,

but for a shorter time.

A timer will cause you grief when you need to crash the ferment at the end.

You will need to experiment to get your system tuned to your needs. I would

play with your differential first, keep reducing it and this may be all you

need to do.

Ian

From: alejandro ramirez <guaild at yahoo.com>
Subject: Problem controling fermetation temp

Hi all! I've recently started fermenting using a 100 gal conical, jacketed
fermenter. I'm attempting to control the temperature using an A419
Johnson temp control, set to start glycol flow through the jacket at, say,
68 deg Fahrenheit. The temperature at which the relay is turned off is
defined by the temp differential, say 3 degs. So, in theory, when the
thermostat reads 68 or higher, the glycol starts to flow, until the temp
falls to 65 degrees.

The glycol is stored in an insulated tank ranging from about 23 to 28
degrees.
The problem is, apparently there is a lag time between the moment
that the correct amount of heat has been drawn out from the wort in
the tank, and the moment that the sensor actually reads the target
temperature and stops the glycol from flowing. So what happens is
that the temperature keeps dropping quite some time after the glycol

has stopped flowing, bringing the temperature way below the lower
limit (say, 57 or 57 degrees). This can have quite adverse effects on
the yeast, as you all know.
Since the fermenting wort is not supposed to be moved around in the
tank (which would homogenize the temp and provide a quicker, correct
read), I figure I might use a timer to limit the flow of coolant for a set

length of time, assuming that the correct amount of heat will be
subtracted from the wort.
An opinion, anyone? Do you think this is the best way to go?
