Aging or failure of equipment may lead to safety accidents. Therefore, regular equipment inspection and maintenance can effectively improve the safety of the plant and prevent safety accidents.
Common maintenance problems in breweries
Equipment aging and failure
As the use time increases, the equipment in the brewery will gradually age. In particular, some high-load equipment, such as fermentation tanks, filters, refrigeration equipment, etc., are prone to failure. Equipment failure will not only lead to production interruptions, but also may affect product quality, so it is necessary to regularly inspect the equipment and replace wearing parts.
Pollution and odor problems
Bacterial contamination and odor problems may occur during the production of beer, especially in the fermentation stage. If the equipment is not cleaned and maintained in time, pollutants may enter the production process and affect the taste and quality of the beer. For example, water pollution in the cooling system and sediments in the pipeline may cause these problems.
Unstable temperature control
The fermentation process of beer is very sensitive to temperature. Failure or instability of the temperature control system may lead to an incomplete or abnormal fermentation process, thereby affecting the taste and alcohol concentration of beer. Maintaining temperature control equipment and ensuring the stability of fermentation and storage temperature is one of the key tasks of brewery maintenance.
Failure of automated control system
Most modern breweries rely on automated control systems to manage the production process. Failure of the automation system may cause problems in various aspects of production, such as inaccurate raw material feeding, uneven fermentation, packaging errors, etc. Such failures usually require professional diagnosis and repair.

Contamination of equipment and pipelines will not only affect the taste of beer but may also cause bacterial growth and cause beer deterioration. Regular cleaning of all equipment that comes into contact with raw materials, yeast, and finished beer is basic maintenance work. To ensure the cleaning effect, many breweries use automatic cleaning (CIP) systems to thoroughly clean brewing and fermentation equipment. During the cleaning process, the cleaning agents and disinfectants used must meet food safety standards to prevent residues from affecting the quality of beer.
Maintenance of temperature control system
The temperature control system is crucial in breweries, especially during fermentation and storage. Even slight changes in fermentation temperature can have a significant impact on the flavor and alcohol concentration of beer. Therefore, regular inspection and calibration of the temperature control system is a key maintenance task. Check the sensors, heating, and cooling systems of the temperature control equipment to ensure their accuracy and stability. At the same time, the system’s pipes and coolants also need to be replaced or cleaned regularly to avoid inaccurate temperature control due to aging equipment, which affects the production process.
Maintenance of automation equipment and systems
Most modern breweries use automation equipment and information management systems to improve production efficiency and accuracy. Automation equipment such as automatic packaging machines, filling machines, brewing control systems, etc. require regular maintenance. To ensure the stable operation of these systems, the factory should be equipped with professional automation technicians to troubleshoot and update the system. In addition, the automation system also needs to regularly back up data and perform software upgrades to prevent system vulnerabilities or data loss from affecting production. Real-time monitoring and alarm systems are powerful tools to ensure production safety and can provide timely warnings when equipment is abnormal.
Replace vulnerable parts in time.
During the long-term use of brewery equipment, some accessories such as pipes, filters, valves, etc. are prone to wear or aging. Regular inspection of these vulnerable parts and timely replacement are the key to ensuring the normal operation of the equipment. When replacing accessories, high-quality original accessories should be used to ensure the long-term stability of the equipment. Especially for key equipment involving raw material processing and fermentation, choosing high-quality accessories can greatly reduce the probability of failure.
Maintaining the plant environment and safety
The environmental sanitation and safety facilities of the brewery also need regular maintenance. Good ventilation, lighting temperature, and humidity control should be maintained in the plant. The work area should be kept clean and tidy to avoid accumulation of debris and prevent fire and other safety hazards. At the same time, the integrity of the fire-fighting equipment, emergency evacuation passages, and safety warning signs in the factory should be checked regularly. For areas where hazardous chemicals are used, their storage and use status needs to be checked regularly to ensure compliance with safety regulations.
Equipment training and technical support
To improve the equipment maintenance level of the brewery, the operators and maintenance technicians in the factory should receive regular equipment training. Operators should understand the basic working principles of the equipment and common troubleshooting methods so that they can solve minor problems in time. Maintenance personnel need to regularly update equipment and conduct technical training to master the latest maintenance skills and equipment maintenance methods. In addition, breweries should also establish complete equipment archives and maintenance records to ensure that the maintenance history of each equipment can be traced back, to facilitate the analysis of the cause of the failure and optimize the maintenance strategy.
