X射线检测系统

X-ray inspection is highly effective at detecting a range of dense physical contaminants including all metals, glass, mineral stone, calcified bone and high-density plastics and rubbers. In addition to identifying contaminants, x ray systems can perform a wide range of inline quality control checks for product integrity, including: measuring zoned and gross mass, identifying missing or broken parts, monitoring fill levels, detecting product trapped within the seal and checking for damaged products and packaging.

The radiation dose levels used for x-ray inspection in the food industry and the pharmaceutical and health industry are extremely low and have no effect on product safety, flavor or texture. The use of x-ray inspection equipment is highly regulated, and increasingly common in both food manufacturing product inspection programs and pharma manufacturing product inspection programs. Modern x-ray systems are perfectly safe in working environments as long as recommended safety guidance is followed. 

An x-ray system can be installed at the beginning of a process to inspect incoming raw goods before adding value to the product, at any stage during the manufacturing processing, or at the end of the production line. The x-ray inspection system conveyor belt can be integrated with current conveyor lines.

Using the Hazard Analysis and Critical Control Points (HACCP) process is the surest way to decide where the system is best placed to prevent products from becoming contaminated in the production process.

Manufacturers should perform a review of their production process and identify any potential risks to product safety. If a risk of physical contamination is identified, a Critical Control Point (CCP) should be established. A reputable x-ray inspection manufacturer such as METTLER TOLEDO safeline can help with the important decision of an industrial x-ray inspection purchase.

False Reject Rate (FRR) is defined as the percentage of falsely rejected products on a production line. Our advanced x-ray inspection software automates product set-up and changeovers to ensure outstanding detection sensitivity levels, minimizing false rejects.

Incorporating industrial x-ray inspection systems into a company-wide product inspection program to help food manufacturers protect product quality and safety, and helps them to comply with national and international regulations, local legislation and standards set by retailers, opening new trade markets.

The product being manufactured and the most likely type and source of contaminants will help you determine whether an x-ray system or metal detector is the most suitable technology. You should also consider the outcome of an HACCP review. In some cases, using both technologies at different critical control points (CCP's) may be the best option. 

Service contracts should be a part of any x-ray system purchase. Regular servicing of an x-ray system, including performance verification, will ensure it is operating at the optimum level of performance. This will prevent food safety issues. Preventative maintenance enables manufacturers to avoid downtime issues due to unexpected maintenance work.
