Customizable 304 Stainless Steel Tunnel Metal Detector with Auto-Reject Function

The Digital Intelligent Tunnel Conveyor Type Metal Detector is designed for food processing applications to detect and remove metal contaminants from production lines. This industrial-grade equipment features advanced electromagnetic wave detection technology with high sensitivity settings.

With a standard detecting tunnel size of 400mm width × 150mm height (customizable), this metal detector can identify ferrous particles as small as Φ0.6mm, non-ferrous at Φ0.8mm, and stainless steel at Φ1.0mm. The machine offers multiple alarm modes including belt-down reject, flap reject, sound and light alarm, or belt-stop functions.

The equipment features a 7-inch touch screen display with Chinese-English interface (other languages customizable) for easy operation. Its advanced phase adjustment technology provides stable detection performance unaffected by temperature changes or machine aging.

Key technical features include auto-setting function for quick product characterization, phase tracking for consistent sensitivity, product tracking for automatic adjustment, and auto-balanced calibration to extend machine lifespan. The IP65-rated 304 stainless steel construction (316 available) makes it suitable for wash-down environments.

This metal detector is widely used in food processing for nuts, rice, meat, tea and wood products. It's also effective for detecting metal contaminants in chemicals, rubber, plastics, textiles, pharmaceuticals, cosmetics and packaging materials.
