Complete Guide to Industrial Automation and Control Systems for Food & Beverage Manufacturing

Process automation in food and beverage operations is making a significant impact, improving throughput, efficiency, and safety. As operators look for greater efficiency, the appropriate control systems can make all the difference.

There’s no shortage of challenges in F&B these days. Production demands are increasing; the cost of goods is rising, and margins are shrinking. Labor struggles continue as a quarter of food manufacturing positions remain unfilled, and the average wage continues to increase, up about 15% since 2020. At the same time, the manufacturing sector has become a growing target for cybercriminals. There was a 61% increase in ransomware attacks in 2025.

Food engineering has taken on an even greater role. PLC programming, SCADA systems, energy management, process automation, control systems, machine safety, cybersecurity: all of these need to work in concert, finetuned to your food and beverage environment.

The Automation Stack in Food and Beverage Manufacturing

Industrial automation in modern food processing facilities today is complex and depends on multiple layers of automation working together. Here are some of the key components that make up the typical automation stack.

These layers only deliver full value when food engineering experts design and integrate these systems into a comprehensive, interoperable solution. It’s more than just upgrading a machine or bolting on a control panel or legacy equipment. You need a complete solution to reduce unplanned downtime and improve production efficiency.

Investment in Automation Is Accelerating Across the Food Industry

Food and beverage manufacturers have embraced industrial automation for decades, although this was typically done at the machine level. To compete today, the priority is plantwide automation supported by integrated control systems and standardized PLC programming.

Globally, F&B producers invested an estimated $27.9 billion in food processing automation in 2025, and that number is forecast to grow to $40.1 billion by 2030. Nearly 80% of manufacturers say they plan continued improvement in 2026, dedicating a significant amount of their budget to greater automation.

Several forces drive this shift:

• The high cost of unplanned downtime
• The need to reduce reliance on manual troubleshooting
• Greater emphasis on traceability and documentation
• Demand for consistent quality across SKUs and shifts
• Increased energy costs and sustainability commitments
• Rising cybersecurity risks requiring hardened system designs
• More advanced equipment requiring unified automation strategies

These factors, collectively, reinforce the need for strong industrial automation planning guided by sound food engineering and control systems design.

Building a Strong Automation Architecture

A solid food engineering plan starts with clear standards, integrated data structures, and coordinated technologies to give operators, maintenance teams, and supervisors the visibility they need.

PLC Programming for Reliable Machine-Level Control

PLCs serve as the real-time control layer ensuring that mixers, conveyors, pumps, ovens, heaters, and packaging systems operate safely and consistently. PLC behavior determines machine speed, sequence logic, alarms, interlocks, and safety functions.

You need:

• Consistent programming structures to support maintainability
• Modular code for easy expansion
• Standardized tag naming and memory allocation

SCADA Systems and the Importance of Plantwide Visibility

Supervisory Control and Data Acquisition (SCADA) systems monitor and control industrial equipment, providing teams with the data and analysis they need to make the right decisions.

Capabilities typically include:

• Production dashboards
• Alarm management
• Historian analysis
• Recipe or batch tracking
• Remote monitoring

This level of visibility helps prevent drift, reduce downtime, and ensure compliance with food safety monitoring and documentation requirements.

Control Systems That Coordinate Processing and Packaging

Control systems keep upstream and downstream processes synchronized and can overlay automation in a cohesive solution. While there may be a long list of process automation tools, they must all work in concert seamlessly for an efficient production environment.

Individual control systems might include:

• Oven-to-cooler transitions
• Filler-to-labeler coordination
• Inspection and reject sequencing
• Case packing downstream alignment

Where Process Automation Replaces Human Variability

Process automation eliminates variation in tasks that require precision and repeatability. For example, with automated loops, you can maintain tighter control over temperature, time, flow, pressure, and composition in applications such as:

• Thermal processes
• Blending and dosing
• CIP and sanitation verification
• Inline measurement and feedback loops

This consistency is especially important when you have a mix of machines in the loop, multiple operators and shifts, or staff turnover. Regardless of the circumstances, food and beverage production demands consistent product manufacturing.

Energy Management as a Growing Automation Priority

Energy management has become a critical part of any industrial automation strategy as utility costs increase. Integrated automation reduces waste and identifies load imbalances in refrigeration, compressed air, steam, and water systems.

Food engineering experts implement load-shedding strategies, utility metering, equipment runtime analysis, and integration with control systems to optimize usage.

Cybersecurity and Operational Resilience in Automated Food Plants

As more systems become interconnected (and connected to the cloud), plants face greater cybersecurity risks. These interconnected systems expand the attack surface and may include equipment that was not originally built for networked environments. The convergence of operational and information technology (OT/IT) is an attractive target for threat actors.

Examples: A ransomware attack at JBS Foods, one of the world’s largest meat companies, shut down production lines, forcing the company to pay $11 million to a Russian hacking group to get back online, and that figure doesn’t include the cost of all the downtime. Molson Coors also fell victim to a cyber-attack, impacting operations and costing the company about $140 million in short-term revenue.

Protecting industrial automation requires rock-solid cybersecurity built into every aspect of your OT and IT systems.

Data Integration Is Key in Automation ROI

Unfortunately, many automation projects fall short of expected ROI because key equipment, inspection systems, and supervisory platforms do not share data effectively. This is more common in operations that have added automation layers onto existing equipment or do not have comprehensive control systems that manage production in its entirety.

Common issues include:

• Disconnected batch and packaging systems
• Equipment-specific dashboards that cannot be consolidated
• SCADA systems lacking historian data
• Missing or inconsistent timestamps
• Alarm floods without prioritization

To achieve meaningful process optimization, SCADA systems, PLC programming structures, and control systems must share consistent data. Best practices include:

• Standard tag structures across all PLCs
• Centralized historian for time-series data
• Integrated quality, downtime, and maintenance KPIs
• Consistent operator dashboards with real-time data

Practical Applications of Industrial Automation in Food and Beverage Manufacturing

Next, let’s look at some of the practical applications for F&B operations and how control systems produce process optimization.

Food Engineering Best Practices

Automated food production needs to integrate mechanical design, controls engineering, and sanitation requirements. Whether you’re producing alcoholic beverages, non-alcoholic beverages, cereals, dairy products, confections, bakery goods, meats, pet food, nutritional products, snack foods, or something else, reliability and safety are critical.

Here are some best practices that need to be engineered as part of your process automation.

Hygienic Controls Design

Automation components must withstand frequent washdown cycles. Approaches include:

• IP/NEMA-rated enclosures
• Hygienic cabling and routing
• Cleanable panel designs

Safety Integration into Modern Control Systems

Functional safety is central to food production, and food processing can be hazardous without the appropriate machine safety controls. This has become a big enough problem across F&B so that OSHA recently put out a hazard alert targeting the food processing industry.

Industrial automation needs to include:

• Guard interlocks
• E-stops
• Safety relays
• Performance level requirements

Aligning Mechanical, Electrical, and Control Processes

Food engineering teams need to design systems in which mechanical behavior and PLC programming logic are synchronized. This alignment prevents unnecessary downtime, inconsistent batching, and excessive manual adjustments.

Energy management is a core part of industrial automation strategy due to its high (but controllable) cost, and the right system can produce significant cost savings. For example, automation enables load balancing, demand response, and runtime optimization across refrigeration, boilers, and compressed air systems. Also, SCADA systems and historians can identify patterns that help you determine when equipment should be upgraded or replaced.

Workforce Efficiency and Skill Development Through Automation

Even with strong automation systems, skilled operators and technicians are essential. Automation doesn’t replace workers, but it does allow them to focus on higher-value tasks and maintain predictable output across different shifts and operators.

Best practices require operator training on industrial automation with an emphasis on standardization and consistency.

Building an Automation Roadmap for Long-Term Growth

Engineering, operations, quality, maintenance, and IT need to be aligned, for true process optimization. Working with expert control systems engineers, you can build an automation roadmap that includes these key phases:

• Infrastructure assessment and controls baseline
• Engineering and sequencing design
• Standardized PLC programming frameworks
• SCADA systems modernization
• Deployment and FAT/SAT validation
• Continuous improvement through process optimization

Your roadmap needs to account for potential changes to F&B operations down the road. You need to be able to scale when demand or production increases, you add additional SKUs requiring changeovers or add AI and machine learning to the mix. This roadmap needs to future-proof your operations, allowing you to scale industrial automation to meet your goals.

Automation KPIs for High-Performance Food Manufacturing

Process optimization requires careful monitoring of key performance indicators. As management expert Peter Drucker said, “You can’t manage what you don’t measure.”

While your KPIs may differ depending on your current and future needs, here are some of the more common metrics which food and beverage producers monitor.

Taking baseline measures and then providing real-time monitoring are key to continued process optimization, showing you the impact of your investment and identifying any constraints that prevent you from achieving the ROI you want.

Reliable, Consistent, Efficient, and Safe Food Production

Industrial automation and modern control systems form the foundation of reliable, consistent, efficient, and safe food production. As throughput demands rise and skilled labor becomes harder to secure, companies that invest in PLC programming standards, SCADA systems visibility, robust process automation, integrated control systems, and long-term process optimization strategies gain a significant competitive advantage.

However, it takes expert automation and control systems engineers, who have the experience working with food and beverage operations, to create a long-term solution that performs consistently under pressure and adapts to your changing requirements.
