Before placing an order, there are so many factors to consider for brewery equipment such as size, number of vessels, type of heat source, cooling the wort, as well as country of manufacturing and engineering origin. One of them is why we need such big glycol tank? Some customers think the glycol is very expensive, it will increase beer brewery equipment investment.
The glycol water tank size can be adjusted according to glycol cooling system configurations in your brewery. It basically has two situations:
1. Without cold water tank in your brewery.
We will need enough bigger glycol water tank + two stages heat exchanger.
(The hot wort will be cooled from heat exchanger by city water at first stage, glycol water at second stage).
1) The wort need to be cooled down to fermentation temperature within 40 minutes from over 100℃, the needed glycol cooling content around 1 times of wort. After glycol made heat exchanging with wort, the glycol temperature will rise to around 35℃ from -5℃, then recycle back to glycol water tank. In order to assure supplying enough cooling content for continuous brewing, the glycol water tank normally is 2 times bigger of brewhouse.
2) The glycol will be used to cool fermentation tanks as well. Under busy brewing days, if there have no enough glycol cooling content, it has influence to fermentation tank cooling. So it always better with enough bigger glycol water tank.
3) With enough bigger glycol water tank, it still can support to add more fermentation tanks for expanding, without upgrading original glycol system. It always is a good thing in the long run.
The glycol will not be consumed. After we filled the tank, we can use it for few years without adding extra glycol. The glycol water tank was closed, the volatilized glycol is less.
If the glycol water tank can meet demands 1)2)3) very well, it always better to have 2 times bigger of glycol water tank. Of course, if you have the plan to use city water to cool hot wort, the glycol water tank size can be smaller.
2. With cold water tank in your brewery
We will need glycol water tank + single stage heat exchanger.
(The hot wort will be cooled by cold water only).
The glycol water will be used to cool fermentation tanks + cold water tank (It has glycol jacket, you can regard it as fermentation tank). The fermentation tank needed cooling content is small, the glycol water tank volume can be smaller.
The cold water tank size normally is 2 times bigger of brewhouse as well. With extra cold water tank, the investment also increase.
In China, second generation chiller is popular, the chiller power is not large like third generation chiller. It normally with 2 times bigger glycol water tank without cold water tank. Of course, if we take cold liquor tank into design, we can decrease glycol water tank capacity accordingly.
The design can apply for all the brewery equipment manufactures in China. We pay more attention to customers' equipment performance and demands.
While in abroad, for example Italian chiller, they are third generation chiller. They have a built-in glycol water tank, around 200L. The chiller power is relatively high. Of course, the cost also is high. It normally work with a 2 times bigger cold water tank.
So the glycol water tank size is related to your brewing process. If you are doubting how to size your glycol tank for your breweries, don’t hesitate to contact me.
