Metal detection for food
Space-saving metal detection with high sensitivity for dried and fresh fruit
Key facts
Pacific Nut Company Chile S.A. produces dried fruits, raisins, prunes and nuts for an increasing demand. In order to be perfectly prepared for the export of its products, the manufacturer contracted Minebea Intec certified Partner Antalis Abitek to improve foreign object detection.
Application & Product

Due to an increased production volume, the Pacific Nut Company Chile S.A. expanded its production and packaging lines in terms of weighing, sealing and box packaging. In the process, also the critical point metal detection needed an improvement. The former metal detector, checking packed boxes of up to 10 kg dried raisins, had shown a lack of detection sensitivity. In addition, thermal fluctuations and changing humidity conditions had led to false rejections. Facing limited space due to the newly expanded production line the customer contacted the certified Minebea Intec Partner Antalis Abitek.
Antalis Abitek has develop a conveyor based metal detection solution. A custom metal detection system Vistus from Minebea Intec was designed and manufactured, and installed at the exit of two bulk product selection lines, prior to weighing and filling in boxes. Mounted on an inclined motorization system with variable speed, pneumatic two-way diverter flap rejection system, and thermoplastic conveyor belt, the metal detector offers fast and easy cleaning processes (IP65).
Through the implementation of a low height multi-frequency detector head, which allows adjusting the rejection times and product passage speeds depending on the production flow, a greater detection sensitivity and efficient contaminant discard now is achieved. The two-way diverter flap rejection system device is pneumatically operated on the detection of contaminated particles inside the product, the compressed air supply activates a flap made of UHWM-PE located at the outfeed of the conveyor. This diverts the contaminated products to a stainless-steel bin. The use of thermoplastic conveyor belt avoids incrustations of products and liquid sugars, allows easy and quick cleaning, requires small amounts of water for the cleaning and disinfection process and dries quickly.
All in all the unique system based on Vistus metal detection technology increases by 40% the detection sensitivity for metallic contaminants, ensuring a high quality assurance standard in the process of raisins for export. “We are highly satisfied with both the performance of Minebea Intec technologies and Partner company,” summarizes Lucio Cordon, Raisins Factory Manager at Pacific Nut about the project.
