Measure - Monitoring of Brewing Parameters Heineken

 Monitoring of Brewing Parameters:

Heineken utilizes the Internet of Things in its brewing process by monitoring specific brewing parameters. The parameters tracked include temperature, humidity, pH levels, pressure, and fermentation speed.

  1. Physical Placement of Sensors:
    IoT sensors are physically installed at strategic locations within the brewery, depending on the parameter they need to measure. Locations where they are deployed include:

    • Fermentation Tanks: These tanks have sensors to measure temperature, pressure, and fermentation speed.
    • Mash Tuns: Here, sensors measure temperature and humidity during the mashing and boiling of the beer.
    • Storage Tanks: Sensors measure the level, pressure, and temperature of liquids during the storage or lagering of the beer.

  2. Data Collection by Sensors:
    The sensors used are equipped with various technologies to take specific measurements:

    • Temperature Sensors measure the heat at different stages of the process. In a fermentation tank, they monitor the temperature of the liquid to ensure that the yeast remains within the optimal temperature range.
    • Pressure Sensors are used to measure the pressure in tanks, especially during fermentation when CO₂ is produced. Excessive pressure can lead to dangerous conditions or quality issues with the beer.
    • pH Sensors measure the acidity/alkalinity of the liquid, which is essential for enzymatic activity and flavor development in the beer.
    • Humidity Sensors are used during the storage of raw materials such as malt. They ensure that the humidity level remains safe so that the ingredients do not spoil or deteriorate in quality.

  3. Data Transmission and Communication:
    A key feature of IoT sensors is their ability to communicate wirelessly. In the Heineken brewery, sensors are often connected to a central computer system via Wi-Fi, Bluetooth, or other low-power wide-area networks (LPWANs). This is done as follows:

    • Wireless Communication: Once the sensors have taken the necessary measurements, they send this data via wireless protocols to a central collection system, such as a cloud-based platform. This enables continuous, real-time monitoring of multiple parameters simultaneously, without the need for physical presence.

  4. Real-time Analysis and Alerts:
    As mentioned earlier, the IoT sensors transmit their data to a cloud-based platform or a local control system. This system analyzes the data in real time and compares it to pre-set optimal values. If a particular parameter falls outside the safe range, an immediate alert is sent to the operator or an automation system for quick intervention.




Benefits

  • Real-time Data: With real-time data from IoT sensors, Heineken can quickly respond to changes in the brewing process. If the temperature in a fermentation tank becomes too high, the system can automatically activate cooling to prevent spoilage.
  • Consistent Quality: By continuously monitoring brewing parameters, Heineken can ensure that every batch of beer meets the same high-quality standards. This is important for their global brand, as consumers expect the beer to taste the same everywhere.
  • Efficiency and Cost Savings: The use of IoT sensors reduces the need for constant human monitoring, lowering labor costs. By making automatic adjustments, the process becomes more efficient and waste is minimized.
  • Waste Reduction and Sustainability: By accurately tracking brewing parameters, Heineken can limit waste and ensure that ingredients are used effectively. This also supports their sustainability goals and reduces energy consumption and costs.

Measure - IoT systems within Heineken's production process

Afbeelding
Heineken’s brewing process is a combination of traditional craftsmanship and advanced technologies, with a strong emphasis on quality, efficiency, and sustainability. The process consists of various steps that are carefully monitored and optimized, and the use of the Internet of Things (IoT) plays an increasingly important role. In general, Heineken’s production process is as follows: Malting : The process begins with soaking and germinating barley to produce malt. This is a crucial ingredient for brewing beer. Mashing : The ground malt is mixed with water and heated, activating enzymes to convert the starches into sugars. Brewing : The liquid, known as wort, is then boiled, with hops added for flavor and preservation. Fermentation : After cooling, yeast is added to the wort, converting the sugars into alcohol and carbon dioxide. This is one of the most important steps, as it determines the taste and quality of the beer. Lagering and maturing : After fermentation, the beer is cooled an...

 We have set up the research question: How does applying Internet of Things (IoT) technology help make Heineken's brewing process better?. To answer this question, we used the 5W2H method to keep things simple and clear. In addition to our main research question, we have developed several sub-questions to guide our study. These sub-questions will help us explore different aspects of how IoT technology impacts Heineken's brewing process. Here are the key sub-questions we will be investigating: - What are possible future developments of IoT - What specific IoT technologies are currently used  - What risks arise when using IoT - How IoT affects Heineken's brewing process 1. What : What are we studying? We are looking at Internet of Things (IoT) technology. We already know that IoT makes it easier to watch over and automate production processes by collecting data through the internet. But what we still need to find out is how Heineken is using IoT and what specific benefits ...

Impact on PCOI IoT at Heineken has a major impact on the PCOI model, which stands for Process, Control, Organization, and Information. By using IoT technology in their brewing processes, Heineken can improve the efficiency and quality of their products and better respond to what consumers want. Process IoT is changing how Heineken manages its brewing processes. Sensors and connected devices continuously collect data on different aspects of production, such as temperature and pressure. This allows employees to quickly intervene if something goes wrong, better safeguarding the quality of the beer. This data also allows Heineken to better respond to trends in demand for different beers, such as seasonal preferences. This helps them adjust their production and reduce waste. Control With IoT, Heineken has more control over its production processes. By analyzing real-time data, they can make quick decisions and solve problems before they become bigger. This not only increases the qua...
