Automation of Production Lines in the Food Industry – Challenges, Benefits, and Practical Implementations

The food industry is facing a paradox today: growing demand for high-quality food, combined with labor shortages, cost pressures, and increasingly stringent hygiene requirements. Automation of production lines in the food industry is no longer a luxury—it has become a prerequisite for competitiveness. In this article, we analyze market data, real implementation challenges, and practical case studies, including a cheese packaging project delivered by MJ Group, a systems integrator specializing in food industry automation and robotics since 2006.

TL;DR
The global food automation market is projected to reach USD 28.7 billion by 2033. While the industry faces key challenges such as strict hygiene requirements (including IP69K and EHEDG standards) and significant upfront investment costs, achieving a return on investment in less than 12 months is increasingly realistic in well-designed implementations. Real-world applications—from cheese packaging to meat sorting—have demonstrated raw material waste reductions of up to 83% and OEE improvements of 15–25%, highlighting the substantial operational and financial benefits of automation in food manufacturing.

Why Is the Food Industry Automation Market Growing?

Market data leaves little room for doubt: automation in the food sector is accelerating at a pace not seen in years. The global food automation market, valued at USD 14.3 billion in 2026, is expected to reach USD 28.7 billion by 2033, representing a compound annual growth rate (CAGR) of 10.4%. The food robotics segment is growing even faster—from USD 2.71 billion in 2025 to a projected USD 14.95 billion in 2034 (CAGR 20.9%).

What Is Driving This Growth?

Labor shortages – particularly in developed countries, where positions involving cold storage work, conveyor operations, and packaging are increasingly difficult to fill. In Poland alone, the vacancy rate in manufacturing consistently exceeds the European average.

Cost and margin pressures – rising raw material and energy costs are forcing manufacturers to optimize every stage of production.

Hygiene and quality requirements – retailers and consumers expect not only great taste but also full traceability and compliance with standards such as BRC, IFS, and FSSC 22000.

Poland is among the European Union countries experiencing rapid growth in industrial digitalization and automation investments, although it still lags behind countries such as Germany and South Korea in robot density. This creates significant growth potential. According to a 2025 survey, 70% of companies planned to maintain or increase automation investments in the coming years.

Key Challenges of Automation in the Food Industry

Implementing automation in a food processing plant is not simply a matter of replacing people with robots. It requires addressing several critical challenges.

Hygiene Standards and Certifications

This is often underestimated but remains one of the most critical challenges. Food industry automation systems must comply with strict requirements, including:

• IP69K – resistance to high-pressure, high-temperature washdowns.
• EHEDG – European Hygienic Engineering & Design Group guidelines.
• ATEX – compliance in explosive environments such as mills and drying facilities.
• NSF H1 food-grade lubricants – approved for incidental food contact.

Failure to comply may result in the loss of BRC or IFS certifications and, consequently, contracts with major retailers.

Product Variability

Unlike automotive manufacturing, where components are identical, food products vary naturally in shape, size, color, and texture. Cheese may be softer, tomatoes less round, and chicken fillets positioned differently. Vision systems and grippers must be adapted accordingly through both software and mechanical design.

Integration with Existing Production Lines

Few manufacturers build facilities from scratch. Automation projects are typically integrated into operational production lines, requiring synchronization with legacy PLCs, conveyors, and SCADA systems. This challenge often determines whether a project succeeds or becomes an expensive retrofit.

Initial Investment and Workforce Reskilling

Investments in robots, vision systems, and integration can amount to hundreds of thousands of euros. Additionally, operators and maintenance personnel require training. Many manufacturers worry that they may “buy a robot and have no one capable of operating it.”

Benefits of Automation – Measurable Results

Despite these challenges, the benefits of automation are measurable and translate quickly into financial performance.

One of the most impressive outcomes is waste reduction. In cheese processing, where traditional cutting and packaging generate losses, robotic systems equipped with machine vision can reduce waste by as much as 83%. For facilities processing several tons of product daily, this translates into annual savings worth hundreds of thousands of euros.

An OEE improvement of 15–25% means not only increased production output but also fewer overtime hours, more stable production planning, and greater confidence in meeting delivery deadlines—an important competitive advantage when supplying major retail chains.

Practical Automation Applications

Dairy Industry – Cheese Packaging (MJ Group Case Study)

One of the most illustrative examples of successful automation in the Polish food industry is a project completed by MJ Group, an industrial automation and robotics integrator based in Wrocław.

The project involved one of Poland’s largest cheese producers. The challenge was straightforward: manual cheese packaging in refrigerated conditions (below 8°C with high humidity). The repetitive and monotonous work led to extremely high employee turnover. HR departments were constantly recruiting replacements, while production depended heavily on labor availability.

The Solution

An industrial robot from the Fanuc family, integrated with a Cognex vision system, took over the feeding, positioning, and packaging process. The system was designed and integrated by MJ Group engineers while meeting IP69K hygiene requirements and using NSF H1-certified food-grade lubricants.

Results

• 24/7 uninterrupted production.
• Elimination of workforce turnover at repetitive workstations.
• Robot investment equivalent to approximately three years of labor costs; afterward, the robot continues operating without personnel expenses, generating annual savings worth hundreds of thousands of złoty.

According to MJ Group, the key to success was not merely the robot itself but comprehensive integration—including communication with the existing packaging line, machine vision capable of handling varying cheese shapes, and compliance with stringent hygiene requirements.

Which Technologies Should You Choose?

Cobots vs. Industrial Robots

This is one of the most common questions among production managers.

Collaborative Robots (Cobots)

Cobots are lightweight machines equipped with force and torque sensors that allow safe operation alongside humans without safety fencing.

They are ideal when:

• Tasks are relatively simple (packaging, labeling, feeding).
• Space is limited.
• Frequent product changeovers are required.

In 2024, cobot adoption in the food sector increased by 21%, while the segment’s global CAGR reached 9.8%.

Industrial Robots

Industrial robots are faster, more precise, and more durable, but they require safety barriers and larger workspaces.

They are best suited for:

• Heavy palletizing (bags, cartons, big bags).
• High-speed cutting and portioning.
• Applications requiring high repeatability in harsh environments such as cold or humid conditions.

Vision Systems and IoT

How to Calculate ROI and Achieve Payback in Under 12 Months

• Direct labor expenses (wages, benefits, overtime, recruitment, turnover).
• Raw material losses.
• Production downtime costs.
• Quality issues and customer claims.

In the MJ Group cheese packaging case, the complete solution (robot, vision system, integration, and training) cost approximately the equivalent of three years of operator wages for a single shift.

After accounting for reduced waste and elimination of labor-related disruptions, the actual ROI was approximately 14 months.

How to Reach ROI Below 12 Months

• Automate high-volume processes.
• Select flexible solutions that can handle multiple product formats.
• Integrate with existing infrastructure whenever possible.
• Avoid over-engineering.
• Implement automation incrementally.

How to Choose the Right Integrator

Choosing an Automation Integrator for the Food Industry

Selecting the right integrator is often the decision that determines whether an automation project succeeds or fails. Here are the key criteria to consider:

1. Food Industry Experience and Regulatory Knowledge

Automation in food manufacturing comes with unique requirements. An integrator should understand the difference between CIP (Clean-in-Place) procedures and IP69K protection standards, know that lubricants must comply with NSF H1 requirements, and ensure that robot designs eliminate crevices where food residue can accumulate.

MJ Group has been delivering automation projects for the food industry for many years and holds ISO 9001:2015 and ISO 45001 certifications, as well as Certified Siemens Solution Partner status.

2. Portfolio and References

Ask for case studies from food industry projects. A qualified integrator should be able to demonstrate successful implementations across packaging, palletizing, and quality inspection applications. If most of their experience comes from unrelated sectors such as automotive manufacturing, they may not fully understand the specific challenges of food production.

3. Technology Independence

A reliable integrator should work with multiple robotics platforms—including FANUC, KUKA, Yaskawa, ABB, and collaborative robot manufacturers—rather than being tied to a single vendor.

This allows the integrator to select the most suitable technology for the process rather than promoting a solution based solely on its existing product portfolio. MJ Group follows this approach, combining experience with leading robot manufacturers and machine vision systems from Cognex, Keyence, and SICK.

4. After-Sales Support and Service

Automation is not a one-time investment. Ensure that the integrator provides operator training, remote maintenance capabilities through IoT technologies, and rapid service response in the event of equipment failures.

For food manufacturers operating 24/7, every hour of downtime has a direct impact on productivity, product availability, and profitability.

5. Local Presence and Market Understanding

Integrators operating within the same country often have a better understanding of local regulations, compliance requirements, and labor market conditions.

Based in Wrocław, with an additional office in Katowice, MJ Group delivers projects not only across Poland but also throughout Western Europe, the Middle East, Asia, and the Americas, demonstrating the scalability of its expertise and project execution capabilities.

Are Cobots Safe for Employees?

Yes. Collaborative robots are specifically designed to operate safely alongside human workers without traditional safety fencing. They incorporate force and torque sensors that detect collisions and immediately stop movement when contact occurs.

In food processing environments, however, companies often supplement cobots with light safety fencing, area scanners, or safety light curtains to provide an additional layer of protection and support risk assessment requirements.

How Long Does It Take to Implement a Robot on a Food Production Line?

A typical implementation takes 8–16 weeks, from the initial audit through commissioning.

• Simple cobot applications: approximately 4–8 weeks
• More advanced projects involving machine vision, MES integration, or IoT systems: typically 3–6 months

Project timelines vary depending on process complexity, facility readiness, and validation requirements.

Which Food Industry Processes Should Be Automated First?

The fastest return on investment is usually achieved in:

• Primary and secondary packaging
• Palletizing and depalletizing
• Vision-based sorting and inspection
• High-volume repetitive operations
• Processes performed in cold, humid, or otherwise challenging environments

These are typically the areas with the highest employee turnover, the greatest labor shortages, and the most costly quality-related errors.

Can a Small Food Manufacturer Afford Automation?

Absolutely. Modern cobots and modular automation systems have significantly reduced the barrier to entry for small and medium-sized food producers.

Entry-level projects can often be implemented for less than PLN 200,000, and when applied to the right process, a 12–18 month payback period is achievable.
