Case Study: Side-View X-ray Inspection for Upright Bottled Products Project Background
In industries such as pharmaceuticals, beverages, and bottled foods, many products are transported and inspected in an upright (vertical) position. Traditional top-down X-ray systems may face limitations when inspecting tall or narrow bottles, especially when detecting fine metal contaminants inside liquid or solid-filled containers. To address this challenge, our side-view X-ray inspection system was applied for the inspection of upright bottled pharmaceutical products, as shown in the test video. Inspection Challenge The customer required reliable detection of thin metal wire contamination inside upright bottles, without laying the bottles down or interrupting the production flow. Key challenges included: Bottles must remain upright during inspection Detection of very small metal contaminants Stable imaging through glass bottles Compatibility with continuous production lines Our Solution: Side-View X-ray Inspection System Our side-view X-ray machine is specially designed for vertical bottle inspection, allowing X-ray imaging from the side instead of the top. This structure significantly improves detection performance for tall bottles and dense products. During the test, the system successfully detected metal wire inside bottled pharmaceutical products, demonstrating excellent sensitivity and image clarity. Case study video:https://youtube.com/shorts/oCHlBrBtFN4?feature=share Suitable Applications This side-view X-ray inspection solution is ideal for upright bottled products such as: Wine bottles Beverage bottles Glass bottles Pharmaceutical bottles It is widely used in food, beverage, and pharmaceutical production lines where product stability and inspection accuracy are critical. Key Advantages Designed specifically for upright / standing bottles Reliable detection of metal, glass, stone, and other dense contaminants No need to tip or reposition bottles Stable operation for continuous production lines Easy integration into existing conveyor systems Cost & Service The starting price is from USD 2***, depending on inspection requirements and configuration. We provide: Professional technical consultation Video demonstrations Sample testing support Customized inspection solutions Contact Us If you are looking for an effective inspection solution for upright bottled products, feel free to contact us for more details.

Metal Detector Inspection for Food Products with Flap Reject System
Application Overview In food processing, even small metal contaminants can pose serious safety risks and lead to product recalls. In this case, our metal detection system is used to inspect finished food products on a production line, ensuring compliance with food safety standards and protecting brand reputation. Product Tested The metal detector is suitable for a wide range of food products, including: Bakery products and snacks Meat and seafood products Frozen foods Packaged and wrapped food items The system can reliably detect common metal contaminants such as ferrous, non-ferrous, and stainless steel. Reject Systems Options for Different Applications To meet different product types, speeds, and installation requirements, our metal detection systems can be equipped with various reject devices, not limited to a single solution. Each reject mechanism is selected based on product characteristics and line layout. Available reject systems include: Flap Reject System: Quickly diverts contaminated products off the conveyor, ideal for packaged food with stable shape and spacing. Pusher Reject (Air or Motor Driven): Gently pushes defective products sideways, suitable for cartons, trays, and flow-wrapped items. Drop / Falling Reject: Uses gravity to remove contaminated products, commonly applied to free-fall or bulk product lines. Retract Belt Reject: Separates products by momentarily retracting a section of the conveyor, effective for fragile or soft food items. Air Blast Reject: Uses compressed air to remove lightweight products such as snacks or small packaged items at high speed. All reject systems are designed to: Ensure accurate and timely removal of contaminated products Minimize product damage and line interruption Improve overall production efficiency and automation level Our engineers recommend the most suitable reject solution based on your product type, line speed, and installation environment, ensuring stable performance in real production conditions. Inspection Result During testing, the metal detector demonstrated: High sensitivity and stable detection performance Accurate rejection of contaminated products Reliable operation under continuous production conditions This helps food manufacturers maintain consistent product quality while meeting international food safety requirements. Free Sample Testing Available To help customers select the right inspection solution, we offer free sample testing. You can send us your product samples, and our technical team will conduct tests and provide detection results and recommendations. Contact Us If you are looking for a reliable metal detection solution for your food production line, feel free to contact us for more information, videos, or sample testing support.

Metal Detection Solutions for Bulk & Free-Flowing Products
In many industries, bulk and free-flowing products such as powders, granules, pellets, and small pieces are especially vulnerable to metal contamination during processing, conveying, or packaging. Ensuring product safety at this stage is critical for both brand reputation and regulatory compliance. Our free-fall metal detection system is specifically designed for the inspection of bulk materials moving through gravity-fed pipelines or vertical chutes. By installing the metal detector before final packaging, manufacturers can effectively detect and remove metal contaminants at an early stage. Typical Bulk Products Applications Flour, sugar, salt, spices, grains Pet food kibbles and feed pellets Plastic granules and chemical raw materials Nuts, seeds, frozen IQF products Key Advantages of Free-Fall Metal Detection High sensitivity to ferrous, non-ferrous, and stainless steel contaminants Stable performance even with high product flow rates Hygienic stainless steel design, suitable for food environments Automatic reject systems to minimize product loss Easy integration into existing production lines With accurate detection and reliable rejection, metal detection for bulk products helps manufacturers reduce recall risks, protect consumers, and maintain consistent product quality. If you are processing bulk or free-flowing materials and want to evaluate metal detection performance, sample testing and application videos are available upon request.

Common Foreign Objects Found in Food Processing — And How to Detect Them
Metal Detectors Metal detectors are effective for identifying ferrous and non-ferrous metals. However, they are limited to metal-only contamination and cannot detect non-metal foreign objects. X-ray Inspection Systems X-ray inspection technology provides a more comprehensive solution by detecting both metallic and non-metallic contaminants based on density differences. X-ray systems can detect: Metal fragments Glass and ceramic Stones and minerals Bones and shells Dense plastics and rubber In addition to foreign object detection, X-ray inspection can also perform quality checks such as: Missing or broken products Weight and fill-level inspection Product integrity verification Why X-ray Inspection Is Becoming the Preferred Choice As food safety regulations become stricter and product variety increases, many manufacturers are upgrading from traditional inspection methods to X-ray inspection systems. X-ray technology offers higher detection accuracy, greater versatility, and reliable performance even for packaged products, including foil or aluminum packaging. Conclusion Foreign object contamination can occur at any stage of food processing, but with the right inspection technology, risks can be significantly reduced. By identifying common contaminants and choosing effective detection solutions, food manufacturers can protect consumers, comply with international standards, and safeguard their brand reputation. If you are looking to enhance your food safety inspection process, X-ray inspection systems provide a proven and future-ready solution.
