INTEGRATED SYSTEMS 34 HYDRAULICS & PNEUMATICS January/February 2025 www.hpmag.co.uk The food and beverage industry faces numerous challenges, particularly when it comes to balancing production efficiency with stringent hygiene and safety standards. As automation continues to play an increasingly important role in modern food production, integrated hydraulic and pneumatic systems are becoming vital components of production lines. These systems, combined with the integration of digital technologies, not only enhance operational efficiency but also ensure compliance with hygiene regulations, reducing contamination risks and improving food safety standards. The backbone of automation in food production As the food and beverage industry increasingly adopts automation, hydraulic and pneumatic systems have become fundamental to achieving the efficiency and precision required in modern production. These systems, particularly when integrated with other technologies such as Internet of Things (IoT) devices, artificial intelligence (AI), and machine learning, create more comprehensive and intelligent automation solutions that enable a more streamlined and error-free production process. Hydraulic systems, with their capability to handle heavy lifting and force-driven tasks, are invaluable in applications such as lifting large containers or equipment. Pneumatic systems, by contrast, are ideal for faster, lighter operations, such as moving products along the production line or handling packaging tasks. The integration of these systems enables food manufacturers to optimise workflows, reducing the time and labour required for manual tasks while improving both speed and quality of production. However, while large, highly automated plants benefit from these sophisticated technologies, smaller or more traditional food manufacturers may still operate with simpler hydraulic and pneumatic configurations. These smaller facilities may use basic systems that support fewer automated functions, but even in these cases, the automation and efficiency benefits of these systems are still highly evident. The degree of sophistication and integration will vary based on factors such as facility size, production scale, and available resources. Ensuring hygiene through integrated automation Food safety is paramount in the food and beverage industry, and hygiene plays a crucial role in maintaining safe products. Contamination risks in food production are a significant concern, and both hydraulic and pneumatic systems must meet stringent hygiene standards. Increasingly, manufacturers are turning to automated cleaning systems integrated within these technologies to ensure continuous compliance with hygiene protocols without halting production. For example, integrated systems can automate cleaning cycles for hydraulic lines, pneumatic valves, and conveyors. Food manufacturers can programme these systems to trigger washdowns or sterilisation procedures based on production schedules, ensuring that cleaning happens seamlessly between production runs or after certain quantities of goods are produced. This automated approach not only saves time but also reduces the likelihood of human error during manual cleaning, ensuring consistency in hygiene practices. While automated cleaning and sanitisation technologies are increasingly common, manual supervision remains an essential part of hygiene management in many food production environments, particularly in smaller facilities. The integration of automation into existing cleaning protocols allows for more precise, consistent, and efficient hygiene practices. However, human intervention may still be necessary, especially during system commissioning or in complex systems where special attention is required. An emerging trend is the integration of sanitation sensors into hydraulic and pneumatic systems. These sensors enable real-time monitoring of hygiene levels, tracking critical parameters like fluid contamination or air quality. If contamination is detected, operators are immediately alerted, allowing them to take corrective actions swiftly to mitigate any risk to product quality and safety. Optimising energy efficiency Energy consumption is a key concern in any industrial operation, and food and beverage manufacturers are no exception. Hydraulic and pneumatic systems, while The role of integrated hydraulic & pneumatic systems in food and beverage production H&P explores how integrated hydraulic and pneumatic systems are contributing to the automation of food production, driving efficiency and cost savings while simultaneously increasing hygiene practices. This discussion considers the role of these systems in both large-scale, fully automated facilities and smaller or more traditional operations, ensuring a comprehensive view of the technology’s application.
