Hi everyone,
We are purchasing the equipment for a 10 bbl brewery, and we are trying to figure out the best setup regarding glycol loop.
For cold-crashing, the maximum we would be crashing in 24 hrs is 20 bbl simultaneously, which would require about 1 ton or 5HP of chilling capacity according to my calculations.
In general, any advice on the glycol loop setup?
Many thanks in advance for all help,
Dieter
We are purchasing the equipment for a 10 bbl brewery, and we are trying to figure out the best setup regarding glycol loop.
For cold-crashing, the maximum we would be crashing in 24 hrs is 20 bbl simultaneously, which would require about 1 ton or 5HP of chilling capacity according to my calculations.
- Right now, we have a single glycol chiller 10HP with built-in 150 L reservoir. Is this wise, or better to get two separate 5 HP chillers in parallel for redundancy in case one breaks down? Is the reservoir large enough?
- - Furthermore, I would like to use this system to help with the process heat exchanger (for cooling down wort between BKW and fermenters i.e. from boiling to 18C). Initially, our suppliers had recommended getting a large 2000L glycol tank in the glycol loop as a buffer, and then using a 2-stage heat exchanger with tap water in 1st stage and glycol in 2nd stage. However, I have read having a large glycol tank is a bad idea because then all 2000L of glycol in the system will be warmed up, which would take time to cool down again and you may be affecting fermenters/brites that may need very cold glycol.
Furthermore, it would cost $4000 for the glycol alone!
So then I adjusted the setup, to turn the glycol tank into a 2000L glycol-jacketed cold liquor tank (CLT) instead, where we would store and cool down tap water, to be used in heat exchanger. In this case, would we still need a 2-stage heat exchanger, or better just 1-stage and use only pre-cooled water, to be dumped in HLT?
In general, any advice on the glycol loop setup?
Many thanks in advance for all help,
Dieter
