Gravity fed metal detector for dried foods
Ensure product purity and safety with metal detection between gravity feed hoppers and packaging systems, minimizing contamination risks in high-speed, continuous operations.

Detects Metal Contaminants in Processing Lines
The IQ4 Waferthin Metal Detector from Loma Systems is a compact, gravity-fed solution engineered to seamlessly integrate between gravity feed hoppers, multi-head weighers, and VFFS bagging machines. With its variable-frequency detection capable of operating between 31 to 882 KHz, it optimizes detection sensitivity for diverse product conditions, whether wet or dry. This makes it ideal for applications in the food and pharmaceutical industries, safeguarding products ranging from cornflakes and chocolate bars to vitamins and herbal supplements. The inclusion of a 7-inch touchscreen enhances user interaction, minimizing setup and maintenance errors. Engineered with stainless steel construction, the detector is designed to withstand IP66 washdown conditions, making it suitable for rigorous operational environments. The system is also equipped with Ethernet and USB capabilities for seamless integration into existing production networks, ensuring comprehensive quality control in continuous, high-speed production lines.
