Overview

The conveyor metal detector is a high-precision inline inspection machine designed for full-automatic metal contamination detection in food, pharmaceutical, and cosmetic production lines. Available in 4 models, with 400mm/500mm detection channels in width and 150mm and 200mm in height, it supports a max conveyor speed of 35m/min for 500mm model or 25m/min for 400mm model, adapting to both packaged and un-packaged products. Adopting advanced multi-frequency electromagnetic detection and intelligent signal processing technology, the equipment effectively eliminates product effect interference from high-moisture and high-salinity materials. It can operate independently or seamlessly integrated with check weight, X-ray inspectors, labeling systems to build a multi-layer end-of-line quality control system, fully complying with HACCP standards to ensure product safety and brand compliance.

FAQ

How about the conveyor metal detector?

Our conveyor metal detector is a high-performance, industrial-grade inline inspection device. It adopts advanced multi-frequency electromagnetic detection and intelligent signal processing technology, featuring stable operation, high sensitivity and strong anti-interference ability. Different from ordinary detectors, it can effectively identify tiny metal impurities and adapt to high-salt and high-moisture products that are prone to false detection. With food-grade hygienic design, flexible linkage functions and easy maintenance, it supports both independent use and multi-equipment integrated deployment, ideal for standardized and intelligent production lines.

What is the application of a conveyor metal detector?

It is widely used for safety inspection in food, pharmaceutical, cosmetic and chemical industries. It covers diversified products including bakery snacks, frozen seafood, meat and poultry products, ready meals, granular seasonings, and various boxed, bagged and tray-packaged products. The equipment can be connect in different positions of the production line, especially for end-of-line finished product inspection, effectively removing metal impurities generated during processing, cutting and packaging to ensure product safety and qualification rate.

What’s the benefit of a conveyor metal detector?

This conveyor metal detector brings multiple core benefits for production enterprises. Firstly, it achieves full-coverage metal impurity detection to eliminate food safety hazards and protect consumer health and brand credibility. Secondly, it fully meets HACCP industry standards to avoid unqualified audits and product recalls. Thirdly, the intelligent anti-interference technology greatly reduces false rejection rate and improves production yield. In addition, it supports intelligent line integration, reduces manual detection costs, improves overall production efficiency, and lowers long-term operation and maintenance costs for enterprises.

How conveyor metal detector work?

The conveyor metal detector operates based on electromagnetic induction principle and intelligent signal analysis system. When products pass through the detection channel with the conveyor belt, the transmitter coil generates a stable electromagnetic field. Any metal impurities inside the product will disturb the electromagnetic field and produce abnormal magnetic signals. The high-sensitivity receiver coil captures the signals in real time, and the system CPU intelligently filters and analyzes the data to distinguish normal product attribute fluctuations from harmful metal contamination. Once unqualified products are identified, the system will automatically trigger rejection, alarm or conveyor stop actions to isolate defective products and complete full-automatic inspection.
