In today's fiercely competitive food processing industry, capacity, operational efficiency, and consistent product quality are essential factors that determine whether a manufacturer can thrive and grow. Companies face increasing pressure to meet rising consumer demand, adapt to new product varieties, and comply with ever-tightening food safety regulations. For many, their existing production lines become bottlenecks that limit growth and increase operational risk.

This case study explores how a mid-sized frozen food manufacturer in Southeast Asia successfully doubled their production capacity, significantly reduced labor costs, improved product consistency, and completed a comprehensive factory automation upgrade in just a few months. Their story provides practical insights and actionable lessons for food enterprises considering similar modernization efforts.

1. Customer Background: Facing Capacity Constraints and Operational Challenges

The customer is a medium-sized manufacturer specializing in frozen convenience foods — including frozen buns, dumplings, fried chicken pieces, and assorted quick snacks. Their annual revenue is approximately RMB 100 million (~$15 million USD), with products primarily supplied to domestic restaurant chains and supermarket retail channels.

Over recent years, demand for their products grew steadily, and especially with clients requesting customized recipes and packaging sizes, the pressure on their production lines intensified. However, the company’s existing semi-automated production line faced multiple challenges:

• Production Capacity Bottleneck: Heavy reliance on manual labor in key processes meant daily output was capped at around 8–10 tons, limiting their ability to scale quickly.

• Frequent Equipment Failures: Aging machinery suffered from frequent breakdowns, leading to an average of 6 hours per week of downtime for repairs and maintenance.

• Quality Inconsistencies: Many quality-critical parameters such as cooking temperature and steaming time were manually controlled, leading to batch-to-batch variability and occasional customer complaints.

• High Labor Costs: Nearly 30 operators per production line were needed to keep the line running smoothly, making labor a major contributor to operational expenses.

The company’s management team recognized that without upgrading and modernizing their production line, their growth trajectory would be severely limited and they risked losing competitiveness in a rapidly evolving market.

2. Customized Production Line Solution: From Process Analysis to Systematic Upgrade

After receiving the inquiry, our engineering team conducted an extensive on-site assessment, including:

• Detailed workflow analysis of raw materials, cooking processes, cooling, packaging, and logistics

• Factory space and utility infrastructure survey
