The Essential Role of Controls and Automation in Process Manufacturing

Efficiency is a critical factor in process manufacturing, and industrial automation systems are indispensable tools for enhancing it. By implementing automation for both simple and sophisticated processes, these systems minimize the need for manual intervention, thereby reducing errors and inconsistencies. This, in turn, drives efficiency gains by accelerating production by speeding up repetitive tasks, optimizing resource usage, reducing operational downtime, and enhancing data precision.

In industries like food processing, automation systems manage everything from ingredient batching and mixing to cooking and packaging. This level of automation speeds up production and ensures that processes run correctly without frequent interruptions. For example, automated ingredient batching systems can add multiple dry material ingredients into multiple scale hoppers at optimal rates to increase batching system capacity by significant levels. A ten-fold increase over manual batching operations is not unusual.  In addition, automatic cooking systems can adjust times and temperatures based on real-time data, leading to more consistent product quality and less waste.

Moreover, automation helps streamline maintenance and operational management. Preventative maintenance, powered by machine and process data, can proactively schedule maintenance of equipment before failures occur. This results in a reduction in unplanned downtime and can extend the lifespan of machinery. This proactive approach enables manufacturers to keep production lines running efficiently and avoid costly interruptions.

In process manufacturing, ensuring high quality and consistency is non-negotiable, and process control systems are critical for achieving both. These automation systems often use advanced sensor technology and control components to monitor and adjust measured process variables in real-time, such as temperature, pressure, flow rates, material weight, and analytical measurements.

Take the chemical industry, for instance. Keeping a tight rein on reaction conditions is critical to ensuring the final product meets your required standards. Automated control systems are great for this—they can monitor your process around the clock and make real-time adjustments to avoid any hiccups that could negatively impact the product’s effectiveness or safety. This means you end up with a more reliable, uniform, and consistent product that is crucial for meeting industry standards, keeping customers happy, and developing brand loyalty.

Additionally, automation makes it easier to keep thorough records and track every step of your production processes. This detailed documentation is crucial for upholding quality control standards and provides the required data for audits and regulatory compliance. By ensuring that everything is meticulously recorded and monitored, automation and control systems boost the reliability and safety of the final product.

Safety is a paramount concern in any work environment, particularly in process manufacturing when dealing with hazardous materials and high-risk environments such as hazardous dust or vapor. Industrial automation and control systems play a significant role in making the workplace as safe as possible by automating dangerous processes and reducing or eliminating exposure to risks for your people.

In industries such as rubber manufacturing, automated control systems handle processes that involve high temperatures, and toxic chemicals. By automating tasks involved with the handling, processing, and manufacturing rubber compounds, manufacturers can minimize the risk of accidents and health issues for workers.

Additionally, automation systems can provide advanced safety features like emergency shutdown protocols and fail-safe operation for equipment and processes. These features are custom-engineered to react swiftly if something goes wrong, helping to prevent accidents and protect your team and equipment. For example, in the grain processing and livestock feed industries, automation systems monitor grinders and milling machines used for particle size reduction of grains. They monitor bearing temperature, mill speed and vibrations. If any of these metrics indicate a potential problem, the control system can trigger a safe shutdown sequence to prevent damage or unsafe conditions, ensuring that everything stays running smoothly and safely.

We are in the era of digital transformation, and GIGO (garbage-in, garbage-out) has never meant more. Data is a high-value asset and industrial control systems can and must excel at harnessing all the data available. These systems gather extensive data on your manufacturing process, providing insights that can drive continuous improvement.

Automation systems are essential for precise ingredient batching, product consistency, and quality control in pet food manufacturing, particularly when handling dry ingredients. For instance, automation systems monitor and manage the batching of ingredients such as grains, proteins, and vitamins in a facility that produces dry pet food. The control system collects real-time data on ingredient quantities, batching system production rates, and mixing times. If the system detects any deviations from the planned recipe ingredient ratios, it will notify operations personnel and take appropriate action.

By integrating data gathered by automation and control systems with other systems such as your ERP, data analytics in the ERP can be leveraged. You can streamline the batching process, reduce ingredient waste, and enhance overall product quality. This approach improves operational efficiency and ensures that every batch of pet food is nutritionally balanced as designed by the nutritionist, meeting both safety standards and customer expectations.

Flexibility is a crucial advantage in fast-changing industrial process manufacturing markets, and industrial automation systems offer significant adaptability. These systems can be easily reconfigured or reprogrammed to accommodate new products, processes, or production requirements.

In the pet food manufacturing example, automation systems can switch between different recipes and packaging formats with minimal downtime. This adaptability allows manufacturers to respond swiftly to changing market demands, seasonal variations, or new product launches. By enabling rapid changes in production setups, automation and control systems help businesses stay competitive and agile in a dynamic market environment.

Industrial automation and control systems are evolving rapidly, incorporating cutting-edge technologies such as the Industrial Internet of Things (IIoT), artificial intelligence (AI), and machine learning. These advancements enhance automation systems, offering the potential to make them more effective.

IIoT sensors could provide real-time data on equipment status and environmental conditions, enabling remote monitoring and control.
