According to our standard configuration, the glycol cooling system for a microbrewery will include a glycol tank, a chiller (second generation, evaporator integrated in the chiller), etc. In addition, we can also supply you with a chilled wine tank according to your requirements.
Here, let’s understand the cooling process together:)
The chillers are all used to cool the glycol (ice) water tanks only.
The temperature of the glycol water is cooled to approximately -5 degrees Celsius (equivalent to 23 degrees Fahrenheit).
If there is no cold liquid tank, the glycol (ice) water tank will be used to cool the wort (in the heat exchanger) and the fermenter/light tank directly.
If there is a cold liquid tank in the cooling system, then the glycol tank will cool the fermenter and the cold liquid tank (it has a glycol jacket).
Its cooling theory is the same as fermentation cooling. The cold liquor tank will cool the wort in the second stage heat exchanger. Our standard configuration will provide two-stage heat exchangers.
By the way, let’s learn more about the heat exchanger (just to clarify the process), it has two stages.
The first stage is to cool the wort with city water. The hot liquid tank will recover the hot water from the heat exchanger (in the first stage). The temperature of the city water can reach about 40-50 degrees Celsius (about 104-122 degrees Fahrenheit).
The second stage is the cooling of the wort to fermentation temperature (from the cold tank) with cold water.
Since the temperature of the first stage wort is mostly lowered by the city water, the temperature of the cold wort in the second stage does not change significantly (from 0 degrees Celsius to about 20 degrees Celsius). Usually, it can still be recycled to the cold tank.
