Best sensitivity Metal Detector for biscuit production line with pneumatic retracting rejector.
Metal Detector for Biscuits
This Biscuit Metal Detector is a high-performance conveyor-style inspection system purpose-built for biscuit and baked goods production lines. Equipped with a pneumatic retracting rejector, it delivers exceptional sensitivity to detect ferrous, non-ferrous, and stainless steel contaminants in raw dough, baked biscuits, and packaged bakery products. Constructed with food-grade stainless steel, the system meets strict food safety standards while ensuring seamless integration into continuous bakery production workflows.
Key Features & Core Benefits
- High Sensitivity Multi-Metal Detection: Identifies even tiny metal contaminants in biscuits, cookies, and baked goods, minimizing product recalls and ensuring consumer safety.
- Pneumatic Retracting Rejector: Efficiently diverts contaminated products without disrupting production flow, ideal for high-speed bakery lines.
- Food-Grade Sanitary Design: Constructed with 304 stainless steel and easy-to-clean conveyor components, meeting hygiene requirements for bakery food processing.
- Stable Conveyor System: Durable food-grade PU belt with adjustable speed, compatible with continuous biscuit production line speeds.
- User-Friendly Touchscreen Interface: Intuitive multi-language HMI with product recipe storage, real-time monitoring, and false reject reduction functions.
- Anti-Interference Performance: Advanced signal processing minimizes false rejects caused by product density variations or bakery line environmental factors.
Wide Applications
This metal detector is tailored for the bakery and baked goods industry:
- Biscuit & Cookie Production: Raw dough, baked biscuits, and packaged cookies
- Bakery Snack Manufacturing: Crackers, wafers, and other baked snacks
- Pastry & Bread Production: Packaged bread, pastries, and sweet bakery products
- Confectionery Bakery: Coated biscuits, filled cookies, and specialty baked goods
How It Works
1. Product Feeding: Biscuits or baked goods enter the detector via the food-grade conveyor belt.
2. Contaminant Detection: The high-frequency sensor scans passing products to identify metal contaminants.
3. Signal Verification: Advanced signal processing distinguishes between actual metal contaminants and product variations to reduce false rejects.
4. Automatic Rejection: If contaminants are detected, the pneumatic retracting rejector activates to divert the contaminated product.
5. Continuous Production: Qualified products continue along the conveyor to the next stage of the bakery line.
Customization Options
widths and lengths to match your biscuit production line dimensions
- Adjustable rejector speed and sensitivity for different biscuit types (soft, hard, coated)
- High-speed configurations for large-volume bakery production lines
