Challenges
1. Viscosity-Induced Seal Failure
The mayonnaise process starts as a low-viscosity liquid, but as emulsification progresses, the viscosity rapidly increases to over 2,000 cP.
This placed excessive load on the bottom mechanical seal, causing frequent seal failure and leakage.
2. Micro-Emulsification Requirement
To produce stable mayonnaise without phase separation, oil droplets must be broken down into very fine and uniform particles.
The existing equipment could not achieve the required micrometer-level particle size distribution, resulting in quality deviation.
3. Contamination Risk Threatening Food Safety
When seal failure occurred, there was a risk of emulsified oil or wear particles entering the product.
This posed a critical food safety issue.
SEDNA Solution
1. SSN High-Shear Magnetic Mixer
SEDNA ENG applied the SSN Series, a fully enclosed high-shear magnetic mixer with no mechanical seals.
By using magnetic coupling technology, the root cause of seal failure was eliminated, enabling stable, leak-free operation even in high-viscosity emulsification processes.
2. Precision Rotor-Stator Technology
A powerful high shear force was generated through the combination of a precision-machined rotor and stator.
By passing the fluid at high speed through the narrow gap, oil particles were uniformly reduced to the micrometer level.
3. Hygienic & Reliable Design
The seal-free structure fundamentally blocks contamination risks and ensures food safety.
In addition, durable bearings and a powerful magnetic design provide reliable performance even during continuous high-load operation.
