Industrial Grade Stainless Steel Food Metal Detector Machine for Food Safety Compliance

What it does in practice is scan packaged or bulk product as it moves along your line — catching ferrous, non-ferrous, and stainlss steel bits that could cause recalls or complaints, and it's not just for dry goods either, our clients run everything from frozen meat blocks to loose powders through it with very few false positives.

The SA-990 will reliably pick up ferrous contaminants down to about 0.5mm, non-ferrous at 0.8mm, and stainless steel at 1.0mm or so — those numbers hold up best when the product is dry and homogeneous, though we've had good results on wet or salty items if you tweak the auto-learn feature first.

Tunnel size is customizable from 200mm wide up to 1200mm, with height anywhere from 50mm to 1000mm — you'll want to match it to your largest package or pouch, and we usually recommend going a bit wider than needed since the conveyor speed range (10-28m/min) handles most throughputs comfortably.

It's built form 304 stainless with an IP67 rating, so you can hose it down without worrying about the electronics, and the touch screen stores memory for 200+ different products — basically you load your settings once for each recipe or SKU and it remembers the sensitivity profile. 5. One thing new buyers don't always think about is the rejection method — you've got push rod, flap drop, or air blast options, and flap drop works better for bulk flow while air blast is cleaner for small packets, so tell us what you're running and we'll help pick (usually 2-4 weeks on custom tunnel builds).

For ordering, the 90-370W motor range covers most load needs up to 50kg, but if your line is heavy or fast, confirm the belt height adjustment (700+100mm) matches your infeed and outfeed — most buyers go with food-grade PU belt materail for durability, though PVC is fine for dry applications at roughly 15% less cost.
