|| Product Introduction
The Vertical Drop Metal Detector for Bulk Food is a vertically falling metal foreign object detection device specifically designed for bulk materials, powders, granules, and free-flowing foods. Installed at the material inlet of the production line, the equipment performs highly sensitive metal detection on the product during free fall, promptly identifying and removing foreign objects such as ferrous, non-ferrous, and stainless steel, thus improving food safety.
This compact and highly sensitive equipment is suitable for online foreign object detection in industries such as grains, nuts, coffee beans, flour, seasoning powders, sugars, spices, and additives.

|| Main Features
1. Vertical Gravity Design
Utilizing the material’s falling motion for detection, this method is faster and has a higher throughput, offering superior performance for bulk foods compared to belt-driven structures.
2. High-Sensitivity Detection Coil
Employing digital signal processing (DSP) technology, it can detect ferrous, non-ferrous metals, and even difficult-to-detect stainless steel.
3. Automatic Rejection System
Equipped with a flip-plate rejection mechanism, it automatically and quickly rejects defective materials upon metal detection.
4. Adaptable to various pre-packaging processes
Suitable for detecting the feed inlet of powders, granules, and bulk foods; commonly used before packaging machines, bag-making machines, and weighing machines.
5. Dustproof and waterproof structure
The equipment can be equipped with IP65–IP66 protection ratings to meet stringent cleanliness requirements in food factories.
6. High-flow-rate detection capability
Can handle high-capacity, high-feed-rate materials without affecting overall production efficiency.
7. Intelligent operating system
Features automatic learning, product formula storage, sensitivity self-adaptation, and statistical output functions.
