The Key Role Of Fermentation Tank Systems In Beer Brewing

The Scientific Principles of Beer Fermentation

Fermentation is a complex biochemical reaction process. Yeast breaks down the sugars in the wort into alcohol and carbon dioxide, while simultaneously generating a large number of flavor compounds, such as esters, aldehydes, and alcohols. These components collectively shape the flavor profile of beer.

The entire fermentation process is generally divided into two stages:

Primary Fermentation – Yeast multiplies rapidly, sugars are quickly consumed, and alcohol content and gas production increase.

Secondary Fermentation or Maturation – The beer flavor gradually balances, bitterness softens, and aromas become purer.

Both stages have strict requirements for temperature, pressure, and time. Improper temperature control or unstable equipment can lead to abnormal flavors or fermentation failure.

Therefore, an excellent beer fermentation tank system must possess the following three key characteristics:

Precise and controllable temperature

Extremely high sealing and hygiene

Scientific structural design for easy cleaning and maintenance

Analysis of the Structure and Function of Modern Fermentation Tanks

1. Material Selection – Advantages of Food-Grade Stainless Steel

Fermentation tanks are typically made of 304 or 316L stainless steel, offering excellent corrosion resistance and a smooth finish.

Mirror-polished inner walls ensure no residue adheres, meeting food-grade hygiene standards.

2. Tank Design – Scientific Structure for Efficient Fermentation

Modern fermentation tanks employ a conical bottom design, facilitating yeast settling and discharge.

The tank is equipped with a cooling jacket and temperature control sensors for segmented cooling.

3. Pressure and Cooling System

The cooling system typically uses a glycol cooling system, allowing independent temperature control for each tank.

Pressure control valves and safety valves ensure stable tank operation and prevent overpressure or gas leakage.

Advantages of DEGONG Fermentation Tanks

As a Chinese beer equipment manufacturer, our fermentation systems possess the following five core competitive advantages in the international market:

1. Precision Manufacturing and International Standards

The equipment employs argon arc welding and full penetration welding processes. Welds undergo pickling, passivation, and mirror polishing, meeting international certification standards such as CE, ISO, and PED.

2. Intelligent Control and Energy-Saving Design

The system integrates automatic cooling control, pressure management, and energy recovery modules, reducing energy consumption by 15%-20%, while supporting data recording and process traceability.

3. Customized Solutions

From 50L pilot systems to 30,000L industrial fermentation systems, we can provide tailored solutions based on the customer's plant space, production targets, and brewing type.

4. High Cost-Effectiveness

Compared to similar equipment from Europe and America, Chinese-made fermentation systems offer only half the price while maintaining quality, and with lower maintenance costs.

5. Global Service Network

The equipment has been exported to countries such as Germany, the United States, Chile, Thailand, Russia, and Australia, and supports remote commissioning and overseas installation.
