How to control the beer fermentation temperature?

Ideally, the brewing process should be tightly controlled within a narrow temperature range for best results! Failure to take the proper steps to properly regulate the thermal aspect of beer production is a costly mistake many new brewers make and it can result in an unsatisfactory product.

1. What is the ideal temperature for brewing beer?

The ideal beer fermentation temperature depends on the type of beer the brewer wants to produce, in general, a satisfactory beer brewing temperature is between 40 and 70 degrees Fahrenheit Lager fermentation temperature: beer fermentation temperature is between 45 and 55 degrees Fahrenheit between enough to reach yeast temperatures for brewing high-quality lagers.

Ale Fermentation Temperature: Ideal fermentation temperature for ale is 68 - 72°F; IPA Fermentation Temperature: Temperatures in the 60°F range can ferment IPA satisfactorily; Stout Fermentation Temperature: Average temperature for brewing a high quality stout Conditions between 64 and 67°F; Pilsner Fermentation Temperature: Fermentation temperature chart classifies pilsner as an optimum fermentation temperature of 50 to 55°F; Fermentation Temperature: When fermenting, the temperature should be adjusted between 50 - 52° Between F.

2. How does the brewery control the fermentation temperature?

In addition to selecting the ideal yeast, selecting and maintaining the optimal brewing temperature is critical to achieving the desired beer quality. Brewery chillers are ideal for large-scale production. Most brewery chillers use ethylene glycol aqueous solutions As a coolant (although there are other refrigerants as well) to keep the chiller pump running smoothly.

3. How does the chiller in the brewery work?

A beer chiller consists of a refrigeration unit, interconnected pipes and an automatic temperature regulator. The cooling liquid is frozen in a freezing tank and then pumped into heat exchange tubes surrounding the fermentation vessel. The heat from the brewing vessel is transferred to the circulating cold water. The cold water liquid is then pumped back into the refrigeration unit for recooling. The overall effect of this heat exchange cycle is to reduce the fermentation temperature inside the brewery vessel.

4. How does the chiller in the brewery adjust the fermentation temperature?

While using chilled glycol as a coolant is very beneficial, it can over-cool the brewing process if not controlled, and to avoid brewing poor quality beer, it is imperative to keep the temperature inside the fermentation vessel constant, this can be achieved with automatic temperature Controller, a temperature-controlled solenoid valve connected to the pipe leading to the heat exchanger.

In addition, a temperature probe is installed through a heat trap in the beer fermentation vessel, which can automatically detect temperature changes during the brewing process, and the valve mechanism will automatically open or close according to the temperature in the fermentation tank, thereby returning to a predetermined value.
