DST

DST developed a patented plant-protein texturization process capable of producing long-fibered meat substitutes — a technically demanding format that most alternative-protein processes cannot achieve. Bringing this technology to commercial scale required extremely precise microdosing of multiple ingredients simultaneously, including proteins, oils, fats, and flavoring compounds. In food manufacturing, even minor deviations in ingredient ratios alter texture, flavor, and nutritional profile, making batch-to-batch consistency both a quality and a regulatory concern. Conventional pneumatic and standard electric actuation systems lacked the positional repeatability required for sub-percent accuracy at production line speeds, putting product quality and the commercial viability of the novel process at risk.

Rockwell Automation engineered an integrated motion and control architecture built around IoT-connected sensors and intelligent drive systems. Allen-Bradley Kinetix servo motors replaced conventional actuators, providing closed-loop precision motion control at each dosing stage. PowerFlex 527 variable-speed drives managed conveyor and process speeds across the line, while PowerMonitor 5000 units captured real-time energy consumption data and fed it back directly into process parameters — creating a continuous optimization loop rather than passive monitoring. GuardLogix safety controllers enforced functional safety requirements across the line without sacrificing throughput. The entire system was programmed and commissioned using Studio 5000 design software, which reduced engineering time and accelerated installation, allowing DST to reach production readiness faster than traditional multi-vendor integration approaches would have permitted.

The Rockwell Automation implementation delivered ingredient dosing accuracy to within 1% across all microdosed components — proteins, oils, fats, and flavoring — meeting DST's repeatability requirements for commercial-scale production. This level of precision is the technical threshold needed to guarantee consistent product texture and taste across batches, a non-negotiable requirement for retail and foodservice supply chains.

• ±1% dosing accuracy achieved across multiple simultaneous ingredient streams
• Energy monitoring closed-loop feeds real-time efficiency data back into process control, reducing waste and improving yield
• Faster installation through unified Studio 5000 engineering environment accelerated time-to-market for the novel meat alternative technology

The integrated architecture also reduced the complexity of ongoing process adjustments, as operators manage motion, safety, and energy monitoring from a single control environment.

• Servo motors now belong in food dosing applications: Where pneumatic or standard electric actuators were once the default, closed-loop servo systems are the only viable option when sub-percent ingredient accuracy is required at commercial speeds.
• Energy monitoring should feed process control, not just reporting dashboards: Integrating PowerMonitor data directly into process parameters turns energy measurement into an active optimization tool.
• Platform consolidation reduces commissioning risk: Using a single vendor's hardware and software stack (motion, safety, drives, HMI) materially shortens installation timelines for novel processes where line debugging time is costly.
• High-accuracy microdosing is a commercialization prerequisite, not a nice-to-have: For emerging food technologies, the ability to prove batch consistency at scale is often what unlocks retailer and co-manufacturer partnerships.
