For sauce producers (ketchup, salad dressing, pasta sauce, etc.), detecting metal contaminants in viscous, flowable products is uniquely challenging: traditional detectors struggle with residue buildup, while tiny equipment-wear fragments (e.g., stainless steel particles from mixers) often slip through low-precision systems. This risk led Spanish salad dressing brand Salsa Fresca—a supplier to 2,000+ European supermarkets—to adopt Shanghai Fanchi-tech Machinery Co., Ltd.’s FA-MD-P50 50mm-Diameter Sauce Pipeline Metal Detector (the equipment shown in our workshop imagery) — a purpose-built solution for online, high-precision sauce inspection.
Prior to 2024, Salsa Fresca relied on a generic pipeline metal detector that failed two critical needs:
“From the first test, the FA-MD-P50 stood out,” says Salsa Fresca’s Production Manager, Carlos Ruiz. “Its 50mm diameter fit our existing sauce transfer pipes perfectly, and it flagged a 0.4mm ferrous fragment in our test batch—something our old detector never would have caught. The smooth stainless steel inner wall also cut cleaning time to 15 minutes per day.”
Since deploying 4 FA-MD-P50 units:
The FA-MD-P50 is engineered to solve the unique pain points of 50mm-diameter sauce pipelines:
Its 50mm inner pipeline (matching standard sauce transfer pipe sizes) integrates seamlessly into existing production lines—no costly pipeline reconfiguration needed. The smooth 304 stainless steel inner wall prevents viscous sauce residue buildup (critical for sticky products like honey mustard or tomato paste).
Calibrated for the tiny contaminants common in sauce production:
Its multi-frequency auto-calibration ignores sauce viscosity and color (e.g., dark tomato sauce), eliminating false alarms.
As visible in our imagery:
The FA-MD-P50’s wheeled stainless steel frame (shown in the top-left workshop image) allows flexible movement between production lines—ideal for small-to-medium sauce producers with multi-SKU workflows.
