The automation system of the brewery not only improves production efficiency, optimizes product quality, reduces production costs, and ensures production safety. The automated brewing system has become a core component of modern breweries. It replaces traditional manual operations through intelligent control systems, thereby achieving precise control of the production process, real-time data monitoring, and remote management of equipment.
What is a brewery automation system?
The brewery automation system consists of a series of interconnected hardware and software. It monitors and controls all stages of beer production in real-time through highly integrated automation technology. These stages include raw material processing, brewing, fermentation, packaging, and other process automation systems. The goal is to achieve precise control, improve production efficiency, reduce labor costs, improve product quality, and minimize human errors.
The automated brewing system mainly achieves comprehensive control of the beer production process through integrated control systems (such as PLC, DCS, etc.), technology, data acquisition and analysis systems, and real-time monitoring platforms. Through the high integration and customization of equipment, breweries can achieve the following core goals:
- Improve production efficiency: The automation system can accurately control the production process and reduce production stoppages and waste caused by human errors.
- Optimize product quality: The precise control of automation equipment keeps the taste, flavor, aroma, and other indicators of each batch of beer consistent.
- Energy saving and consumption reduction: Automation technology helps to optimize energy utilization, reduce energy consumption in the production process, and reduce unnecessary waste of resources.
- Ensure food safety: The automation system ensures that the production process meets food safety standards through real-time monitoring, data recording, and traceability.
The main equipment of the automated brewing system
Raw material handling system
Processing is the first step in beer brewing, including the preparation of malt, hops, water, and beer. The automated raw material handling system monitors the delivery, mixing, and piping process of raw materials through precision raw material equipment and sensors. The system includes the following main components:
- Malt crusher: crushes malt particles into suitable particles to facilitate the extraction of sugar. The automated control system can adjust the working parameters of the equipment according to the requirements of the crushing particle size.
- Automated batching system: used to accurately control the ratio of different raw materials. The system automatically measures, pipes, and mixes raw materials according to the set formula and production batch.
- Water treatment equipment: ensure that the water quality meets the requirements of beer production. The automated water treatment system includes water quality monitoring, filtration, softening, and disinfection equipment, and monitors the water quality in real-time through sensors to ensure the stability of water quality during the brewing process.
Sistema de fabrico de cerveja
Brewing is the core link of beer production, involving multiple processes such as mash, boiling, and cooling. The sistema de fabricação de cerveja automatizado ensures that every step of the brewing process is carried out under the best conditions by precisely controlling parameters such as temperature, time, and pressure. The main equipment includes:
- Mash Tun: used to mix malt with water and convert starch into sugar through the heating process. The mashpot is usually equipped with a temperature control system, a stirring system, and a liquid level monitoring system to ensure the efficient mash
- Brew Kettle: During this process, hops are added and boiled to extract aroma and bitterness. The automation system controls the boiling temperature, time, and amount of hops added to ensure the consistency of flavor.
- Heat exchanger: used to quickly cool the boiled wort to the fermentation temperature. The automation system ensures the efficiency and stability of the cooling process and avoids the impact of temperature fluctuations on fermentation.
Sistema de fermentação
Fermentation is one of the most critical stages in beer brewing, which converts sugar into alcohol and fermentation. The automated fermentation system ensures the stability of the fermentation process by accurately controlling factors such as temperature, pressure, and pH. The main equipment includes:
- Fermentation tank: It is the main container for fermentation, usually equipped with automation equipment such as temperature control, pressure sensor, and liquid level monitoring to achieve precise environmental control.
- CO2 recovery system: By capturing the high CO2 generated during the fermentation process, it is recovered and used in other production stages. The automated CO2 recovery system can be used to monitor the generation and recovery efficiency of high CO2 in real-time.
- Automated dissolved oxygen system: During the fermentation process, the oxygen content has an important influence on the activity of yeast. The automated dissolved oxygen system monitors the dissolved oxygen content in real-time through sensors and adjusts the gas supply to ensure the smooth progress of fermentation.
Warehousing and logistics system
Beer after fermentation usually needs to be filtered and packaged. The automated filtration system can effectively improve the suspended matter, yeast, etc. in the beer to ensure the clarity and stability of the beer. The automated packaging system ensures that the filling volume, number of bottles, cap seam, label printing, etc. of each bottle of beer meet the standards. The main equipment includes:
- Filtration system: including filter presses, centrifuges, etc., used to improve the accuracy of beer. The automated system ensures the filtration effect by monitoring the filtration speed, filtration pressure, and quality of the beer.
- Filling line: Automated filling uses precise filling machines to ensure the accurate capacity of each bottle of beer and avoid waste. The filling system needs to be equipped with sensors to detect in real-time whether the bottle mouth is clean and the bottle cap is tight.
- Packaging and packaging line: Automated packaging equipment ensures that the packaging, labeling, and packing processes of beer bottles are efficient and fast. This system is usually linked with the logistics management system to realize the automated management of inventory.
Filtration and packaging system
Through automated conveyor belts, stackers, and filling dock management systems, breweries can realize automated warehousing, storage, and outbound operations.
Brewing process with automated systems
- Mashing: Grains are soaked in hot water to convert starches into fermentable sugars. Automated systems maintain precise temperatures to ensure optimal enzyme activity. With programmable steps, you can easily manage temperature rests for complex beers such as lagers or wheat beers.
- Filtration: After mashing, wort (the sugary liquid) is separated from the grains. Automated systems use pumps and valves for filtration, providing a constant flow rate to avoid clogging and ensure maximum sugar extraction.
- Boiling: During the boiling process, hops are added to the wort to add bitterness and flavor. Automatic boil kettles allow you to set the amount of hops to be added at a specific time, ensuring a consistent taste.
- Cooling: Cooling the wort quickly is essential to prevent contamination and prepare for fermentation. Advanced chillers in automated systems make this process fast and efficient.
- Fermentation: Fermentation takes place in temperature-controlled fermenters. Automated equipment monitors temperature, pressure, and CO2 levels to optimize yeast performance and beer quality.
- Packaging: Some automated systems also assist with kegging or bottling, providing an end-to-end brewing solution.
Types of automated brewing systems
Home brewing system
Home brewing is becoming more and more popular, and with it has come the emergence of user-friendly automated systems designed for home use. These systems often strike a balance between automation and manual control, allowing hobbyists to fine-tune the brewing process while still enjoying the convenience of automation.
