High Sensitivity Free Fall System Gravity Fed Metal Detector for Flour & Powder for Food Industry
Introduction&Application
The sensitive sensors in the Fanchi-tech Inspection gravity feed metal detectors detect even the smallest metal contaminants, and fast-switching separation flaps discharge them directly from the product stream during production.
Product Highlights
1.Reliably detects all type of metals in free-falling goods
2.Compact installation space by minimized metal-free zone
3.Auto parameter setting by intelligent product learning
4.Simple assembly due to mounting frame and quick release rings
5.Anti-interference photoelectric isolation drive allows remote installation of operation panel.
6.Higher interference proof by multi-filtering algorithm and X-R orthogonal decomposition algorithm.
7.Maximum inspection performance with highest reliability in the entire detection area due to hard-fill technology and adaptive DDS and DSP technology
8. SUS304 frame and major hardware parts by CNC tooling.

Q: What products and production scenarios is this gravity-fed metal detector suitable for?
A: Also known as a drop-through or free fall metal detector, this FA-MD-P model is purpose-built for pre-packaging inspection of continuously flowing free-falling powders and granules. Typical applications include flour, sugar, plastic granules, gravel, tablets and capsules, making it ideal for bulk processing lines in food, chemical and pharmaceutical industries.
Q: What metal contaminants can it detect, and what technologies guarantee reliable detection?
A: It reliably detects all common metal contaminants: ferrous metals, non-ferrous metals (such as aluminum and copper) and stainless steel. It leverages hard-fill technology with adaptive DDS and DSP technology to deliver consistent high sensitivity across the full detection area. Multi-filtering algorithm and X-R orthogonal decomposition algorithm further provide strong resistance to vibration and electrical noise on the production floor.
Q: What pipe sizes are available, and how easy is installation and integration?
A: Five nominal diameters are available: 50mm (2”), 100mm (4”), 150mm (6”), 200mm (8”) and 250mm (10”). It features a compact footprint with a minimized metal-free zone to save installation space. The mounting frame and quick release rings enable simple, tool-light assembly. Thanks to anti-interference photoelectric isolation drive, the operation panel can also be installed remotely for flexible line layout.
Q: How does it remove contaminated material, and is product changeover efficient?
A: It triggers sound and light alarm upon metal detection, and is equipped with a fast-switching auto-flap valve rejector that discharges contaminated fractions directly from the product stream without halting production. It supports intelligent product learning for automatic parameter calibration, and can store up to 100 product presets to enable fast, seamless product changeover.
Q: What material is the machine constructed from, and what is the maintenance requirement?
A: The frame and all major hardware parts are made of 304 brushed stainless steel with CNC machining, meeting strict food industry hygiene standards and CE conformity. The built-in sensors are self-calibrating and maintenance-free, greatly reducing routine upkeep workload. It operates stably in 0–40°C temperature and 0–95% non-condensing humidity, suitable for long-term continuous production.
