Multiscan MXV-Bulk X-ray System Reveals Hidden Nut Defects
Nut processors have traditionally relied on optical sorting, which reads external characteristics such as color, size, and shape but can't detect what's happening inside the shell. The Multiscan MXV-Bulk X-ray inspection system closes that gap by analyzing density differences inside each in-shell nut to identify hidden quality defects, insufficient kernel fill, and dense foreign material (FM).
Nuts move through the system on a belt designed to stabilize and distribute product evenly for consistent scanning. As each nut passes through the inspection zone, the system captures and analyzes images to assess internal density; when it detects out-of-tolerance product or FM, it signals air valves to eject the unwanted material from the line.
Operators set the density threshold directly on a touchscreen, defining the tolerance that determines how fully a nut must be filled to be accepted. The system can also evaluate fill within specific areas of each nut, allowing inspection to be configured for differences among varieties and quality targets.
Weco's MXV-Bulk identifies and rejects defects that show no external signs—including empty shells, insect damage and internal mold—along with FM such as stones, glass, ceramics and embedded metal. It's built for pecans, walnuts, pistachios, peanuts and other in-shell nuts. It's intended to work alongside optical sorting and aspiration on the line, adding internal density data to those existing separation methods.
