Fanchi-tech Conveyor Metal Detectors: Precision Safety for High-Volume Biscuit & Cookie Production

The global biscuit and bakery industry faces unique challenges when it comes to food safety: high-speed production lines, diverse product formats (from single-serve cookies to bulk family packs), and the constant risk of metal contamination from processing equipment. Biscuits’ high fat, sugar, and salt content also creates strong “product effect” interference, which can overwhelm conventional metal detectors, leading to costly false rejects, production downtime, and unaddressed safety risks. For leading biscuit manufacturers, reliable, bakery-specific metal detection is no longer optional—it’s a critical requirement to protect consumers, meet retailer standards, and safeguard brand reputation.
Fanchi-tech’s purpose-built conveyor metal detectors are engineered to solve these exact challenges. Designed for the demanding conditions of biscuit production lines, these systems deliver consistent, high-precision metal detection while minimizing waste and maximizing line efficiency.

Engineered to Overcome Biscuit Production Pain Points

1. Advanced Detection Technology to Beat Product Effect

Biscuits, cookies, and baked goods are among the most challenging products for metal detection due to their high conductivity (from fat, salt, and moisture) and varying densities. Fanchi-tech’s metal detectors use advanced dual-frequency adaptive technology and high-performance digital signal processing (DSP) to automatically suppress product effect interference, distinguishing genuine metal contaminants from natural product signals. This allows the system to reliably detect ferrous, non-ferrous, and 300-series stainless steel fragments as small as 1.0mm—even in high-moisture, high-fat baked goods—while keeping false reject rates below 0.3%.

2. High-Speed, High-Capacity Design for Continuous Production

Built for the fast pace of modern biscuit manufacturing, Fanchi-tech’s systems feature wide, long food-grade conveyor belts (visible in our workshop configuration) that seamlessly integrate with high-volume lines, processing hundreds of biscuit packs per minute. The large, open aperture design accommodates diverse product formats, from individually wrapped cookies to carton-packed assortments, without compromising detection sensitivity. Optional automatic reject mechanisms (including precision push-rod diverters or air-blow systems) remove contaminated products quickly and cleanly, eliminating disruptions to production flow.

3. Hygienic, Durable Construction for Bakery Environments

Bakery facilities require equipment that can withstand daily cleaning, grease buildup, and high-moisture conditions. Fanchi-tech’s biscuit metal detectors are constructed from food-grade 304 stainless steel, with crevice-free surfaces and easy-to-clean components that meet GMP, HACCP, and food safety standards. The sealed control panel and corrosion-resistant frame resist damage from cleaning chemicals and grease, ensuring long-term reliability in harsh production environments. Mobile casters allow for flexible positioning and easy access for maintenance or line reconfiguration.

4. User-Friendly Operation for Bakery Teams

Equipped with an intuitive touchscreen HMI and multi-language support, Fanchi-tech’s metal detectors simplify daily operation for bakery staff. Operators can store and recall custom product profiles for different biscuit SKUs, reducing changeover time between production runs. Built-in data logging automatically records inspection results, reject events, and system performance, creating a complete audit trail for compliance with retailer and regulatory requirements.
