Food-Grade Starch Screw Conveyor with Integrated Neodymium Drawer Magnet

The Challenge: Ensuring Zero Metallic Contamination in Bulk Bakery Ingredients
A large-scale industrial bakery producing buns and cookies required a high-hygiene solution for transporting bulk starch. In a high-volume food environment, the risk of fine ferrous (metal) contamination—whether from upstream processing or raw material transit—is a major safety concern. The system needed to not only convey the starch efficiently but also provide a “fail-safe” mechanical barrier to capture microscopic metal fragments before they entered the final mixing stage.

The Solution: Hygienic Starch Auger with High-Intensity Magnetic Separation
We engineered a specialized Stainless Steel Screw Conveyor featuring an integrated final-stage purification system:
We engineered a specialized Stainless Steel Screw Conveyor featuring an integrated final-stage purification system:
- High-Intensity Neodymium Drawer Magnet: At the discharge outlet of the auger, we installed a custom drawer-style magnetic separator. This unit utilizes high-strength Neodymium magnetic bars, which provide the superior Gauss strength required to pull even the smallest paramagnetic particles from the starch stream.
- Easy-Clean Drawer Design: The magnet is housed in a “drawer” configuration, allowing quality control teams to quickly slide the bars out for inspection and cleaning without dismantling the conveyor.
- Full Stainless Steel Construction: Every contact part, from the screw flights to the magnetic housing, is manufactured from food-grade stainless steel to ensure full compliance with food safety audits.

The Result: Audit-Ready Ingredient Purity
The addition of the neodymium magnetic bars transformed the conveyor into a critical quality control point. By catching metallic impurities at the final discharge, the bakery significantly reduced the risk of product recalls and equipment damage, ensuring their buns and cookies meet the highest retail safety standards.
