Zero-dead-leg design eliminates stagnant areas where product and bacteria can accumulate. Roben Manufacturing designs food-grade reactors with zero-dead-leg principles.
Why Choose Zero-Dead-Leg Food Reactors
Dead legs are pipe sections or cavities where product stagnates—creating bacterial growth sites and contamination sources. Zero-dead-leg design ensures all areas are swept by product flow and cleaning.

Frequently Asked Questions
We provide finishes from standard mechanical polish through mirror electropolish. Common specifications include 32 Ra (0.8 µm) for general food, 20 Ra (0.5 µm) for dairy, and finer finishes for pharmaceutical-grade applications. All finishes are documented and verified.
Yes, we design and manufacture reactors to 3-A Sanitary Standards. Our 3-A compliant vessels include appropriate surface finishes, crevice-free construction, drainability, and other requirements specified in applicable 3-A standards.
304 and 316L stainless steel are standard FDA-compliant materials for food contact. We also use FDA-compliant gaskets, seals, and other components. All food contact materials are documented for regulatory compliance.
Yes, we design reactors with integrated CIP (Clean-In-Place) and SIP (Steam-In-Place) capability. This includes spray device mounting, complete surface coverage, self-draining construction, and appropriate steam distribution.
Lead times typically range from 14-22 weeks depending on size, complexity, and finish requirements. Mirror-polished, electropolished, or 3-A certified vessels may require additional time for surface finishing and documentation.
