X-Ray Inspection and Checkweighers
MPI’s X-Ray Inspection and Checkweigher Systems offer cutting-edge technology for contaminant detection, product integrity verification, and weight compliance across a wide range of packaging formats and production environments. Designed to meet the most demanding food safety and quality assurance standards, these systems help manufacturers ensure product safety, prevent recalls, and maintain brand trust.
X-Ray Inspector for Packaged Products provides high-resolution imaging to detect metal and non-metal contaminants—such as glass, bone, rubber, and stone—inside sealed, boxed, or wrapped goods. For loose or unpackaged materials, the X-Ray Inspection for Bulk Products system delivers accurate inspection of flowing product streams like nuts, dried fruit, or granulated ingredients.
Specialized solutions like the X-Ray Inspection for Glass, Jar, and Can Lines use beam angle optimization to overcome packaging interference and provide reliable contaminant detection in dense, curved, or opaque containers. The X-Ray Inspector for Liquid Products is ideal for high-throughput pipelines, identifying unwanted objects in beverages, sauces, or viscous fluids before bottling.
MPI’s high-speed Checkweighers ensure every unit meets target weight specifications, reducing giveaway and improving packaging efficiency. For streamlined operation, the Combination Metal Detector and Checkweigher integrates contaminant detection and weight verification in one compact, space-saving solution—ideal for maximizing efficiency without compromising compliance.
Packaged Product X-Ray Inspector
The X-Ray Inspector for Packaged Products delivers advanced contaminant detection for sealed, boxed, or wrapped items across food, pharmaceutical, and consumer goods industries. Utilizing high-resolution imaging, this system identifies a wide range of foreign objects—including metal, glass, stone, bone, and dense plastic—regardless of product shape or orientation. Ideal for quality assurance at the end of the production line, it ensures safety without damaging or slowing down the packaging process. The intuitive interface allows for easy setup, automatic product learning, and real-time reject tracking. Its compact footprint and hygienic design make it an ideal fit for space-conscious production.
Bulk Product X-Ray Inspector
MPI’s X-Ray Inspection for Bulk Products offers precise, high-speed inspection of free-flowing, unpackaged goods such as nuts, grains, dried fruits, or granules. Designed for early-stage processing, this system detects contaminants before packaging, preventing costly downtime or rework. Its wide inspection window and intelligent image processing ensure thorough analysis of irregularly shaped materials. The system features hygienic construction, easy-clean components, and an integrated reject mechanism to isolate contaminated material efficiently. With its reliable performance and customizable configurations, it is ideal for processors who require strict contaminant control while maintaining high throughput in dry or semi-moist bulk product environments.
Glass, Jar, and Can Line X-Ray Inspector
Specifically engineered for curved or opaque containers, MPI’s X-Ray Inspection for Glass, Jar, and Can Lines use angled beam geometry to detect contaminants hidden at the bottom, sidewalls, or neck of thick-walled packaging. This specialized system overcomes the challenges posed by metal lids, dense liquids, and variable product shapes to ensure accurate detection of glass shards, stones, and metal fragments. With high-speed inspection capabilities and reject control tailored to individual container types, it ensures safety and compliance in high-volume beverage, condiment, and ready-meal lines. Hygienic construction and automated calibration simplify maintenance while supporting food safety certifications.
Liquid Product X-Ray Inspector
The X-Ray Inspector for Liquid Products is designed for high-throughput inspection of fluid and semi-fluid products such as juices, soups, sauces, and dairy-based beverages. Integrated into pressurized filling or pipeline systems, it continuously scans for metal, glass, or dense plastic contaminants without disrupting flow or pressure. The system supports CIP (Clean-In-Place) protocols and offers a sanitary design that meets the highest hygiene standards in beverage and liquid food production. Its advanced software adapts to different viscosities and flow rates, enabling accurate, non-intrusive inspection. Real-time reject functionality and intuitive control panels make it a powerful solution for fluid line safety.
Checkweigher
MPI’s Checkweigher system ensures every product meets weight compliance by delivering high-speed, high-accuracy inspection of packaged goods. Whether installed after filling or final packaging, this system verifies that products fall within predefined weight tolerances, reducing giveaway and ensuring consistent product quality. It features durable stainless-steel construction, a user-friendly touchscreen interface, and the flexibility to handle a wide range of product types and sizes. Built for continuous operation, it can be integrated with rejection systems for automatic removal of under- or overweight packages. Designed for demanding food, pharma, and industrial packaging lines, MPI’s checkweigher supports operational efficiency and compliance.
Combination Metal Detector and Checkweigher
The Combination Metal Detector and Checkweigher merges two essential inspection functions into one compact, space-saving unit—making it ideal for manufacturers with limited line space. This integrated system simultaneously detects metal contaminants and verifies product weight, helping maintain safety, regulatory compliance, and packaging accuracy in a single pass. Engineered for seamless operation, it features a unified interface for easy control and data tracking. Both components are optimized for speed and precision, ensuring minimal false rejects and smooth product flow. The hygienic design, modular construction, and compatibility with industry standards make it a smart investment for food, pharma, and general manufacturing.
