WECO Introduces Multiscan MXV-Bulk X-Ray Inspection System for Nuts
WECO has introduced the Multiscan MXV-Bulk X-ray inspection system for in-shell nut applications. The system analyzes density differences inside each nut to identify hidden quality defects and insufficient kernel fill, as well as dense foreign material. By removing these from the product stream, the MXV-Bulk helps processors achieve higher product grades, increase per-pound value, and reduce the need for manual inspection.
WECO says the Multiscan MXV-Bulk X-ray inspection system is the first system of its kind to evaluate the internal quality of in-shell nuts in North America. Ideal for inspecting pecans, walnuts, pistachios, peanuts, and other nuts, the MXV-Bulk system identifies and rejects a wide variety of product defects that show no obvious external signs including empty shells, insect damage, and internal mold. It also removes foreign material including stones, glass, ceramics, and embedded metal.
Nuts enter the system on a belt designed to stabilize and distribute product evenly for consistent scanning. The MXV-Bulk captures and analyzes images of each object as it passes through the inspection zone. When it identifies out-of-tolerance product or foreign material, it signals the air valves to eject the unwanted material.
MXV-Bulk complements optical sorting, aspiration, and other separation methods on the line. Optical sorters identify external characteristics such as color, size, shape, and surface condition, while aspiration separates material based primarily on weight and aerodynamic properties. X-ray inspection adds information about internal density, helping processors build a more complete quality-control strategy.
Designed for straightforward operation, the MXV-Bulk does not require a highly specialized operator to maintain consistent results. Operators set the density threshold directly on the 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.
MXV-Bulk was developed through collaboration between WECO and Multiscan Technologies, both Duravant operating companies, by combining Multiscan's X-ray technology with WECO's nut processing expertise. MXV-Bulk is available for sale worldwide and for lease in the U.S., Mexico, and Canada. WECO supports processors with installation and startup services, preventive maintenance, technology upgrades, and 24/7 emergency assistance to help sustain inspection performance and production uptime throughout the life of the equipment.
