Brewing beer involves two key stages: mashing and fermentation. The unfermented beer, known as "wort," has a hop aroma but is non-alcoholic. During fermenting, yeast converts the sugar in the wort into alcohol, which gives beer its signature taste and aroma. However, the quality of fermentation can make or break the final product. Proper fermentation can create complex flavors and a smooth, balanced beer, while incorrect fermentation can result in off-flavors, poor carbonation, and low-quality beer.
Choosing the right fermenter is critical for brewing a quality beer. Tiantai's fermenters are specifically designed for the beer brewing process, with a conical bottom to reduce disturbance during the removal of spent yeast and other trubs. The angle of the cone determines the efficiency of the setting process, smaller angles allow more efficient settling. The height and the diameter-to-height ratio of the tank are also optimized for the fermentation process, promoting the natural convection of the beer in the tank, and reducing agitation.
To control the temperature during fermentation, Tiantai's fermenters are equipped with cooling jackets, which can meet the cooling requirements of the process. The cooling jackets consisting of dimple jacket, uses ethanol or glycol as refrigerants to cool the fermentation process. The cylindrical part of the tank features 2 to 3 pieces of cooling jackets, which are turned on according to the process requirements to achieve the ideal cooling effect. The temperature in different parts of the fermenter will vary during fermentation, with higher temperatures at the top and lower temperatures at the bottom. For this reason, the cooling in the upper part of the tank body is strengthened in the primary fermentation stage, while the cooling at the bottom of the tank is increased during the secondary fermentation stage.
The interior surface of the fermenter is also critical for the quality of the finished beer. The surface needs to be as smooth as possible to prevent the growth of microorganisms. The surface treatment of the welds is also important, as bacteria can multiply in the rough parts of the tank wall, causing contamination. Tiantai's beer fermentation tank is made of food-grade stainless steel, which has been pickled and passivated to ensure a polished finish of 0.2~0.4μm without dead angles, reducing the working pressure of cleaning and sterilization.
In conclusion, the quality of beer fermentation cannot be overstated in the brewing process. It has a major impact on the taste, aroma, and overall quality of the finished product. Tiantai's fermentation tanks, with the conical bottom, cooling jackets, and food-grade stainless steel construction, are designed and manufactured to meet the specific requirements of the beer brewing process, ensuring optimal fermentation conditions, and reducing the risk of contamination. By choosing the right fermentation equipment and closely monitoring the fermentation process, brewers can produce high-quality, flavorful beer that will satisfy even the most discerning beer drinkers.
