As food safety issues are increasingly valued, the application of X-ray food inspection equipment in the food industry is gradually becoming popular. The equipment uses the penetration of X-rays and the difference in the absorption of X-rays by different materials to detect foreign matter that may be present in food, such as metal, glass, plastic, etc., to ensure the safety of food. However, like all high-tech equipment, food inspection systems may also have some faults during long-term operation, affecting their normal operation. This article will introduce in detail the common faults of food x-ray inspection equipment and their solutions to help manufacturers effectively deal with equipment failures and ensure the accuracy and efficiency of food inspection.
1. Common faults of X-ray food inspection equipment
Abnormal image display
Fault description: X-ray food inspection equipment usually presents the inspection results through image display. If the display image of the equipment is abnormal (such as blurry, dim, unclear, etc.), it may cause the inability to correctly identify foreign matter, thereby affecting the inspection effect.
Possible causes: The causes of abnormal image display may include detector failure, image processing software problems, loose or damaged connection lines, unstable X-ray source power, etc.
Solution: First, check whether the connection line between the display and the control system is normal and ensure that it is not loose or disconnected. If the connection is normal, check whether the image processing software needs to be updated or restarted. If it is a detector problem, you need to contact the equipment supplier for repair or replacement.
Unstable radiation dose
Fault description: The radiation dose of the X-ray equipment is unstable, which may lead to inaccurate test results. Long-term dose fluctuations may lead to a decline in the detection performance of the equipment and affect the detection ability of food safety.
Possible causes: Aging of the radiation source, unstable power supply inside the equipment, control circuit failure, etc. may all lead to unstable radiation dose.
Solution: Check the status of the X-ray source and replace or maintain it if necessary. It is also necessary to check the stability of the power supply voltage to ensure a stable voltage supply. If there is a problem with the control circuit, it is recommended to contact professional technicians for maintenance.
Unable to start the equipment normally
Fault description: Sometimes the X-ray food inspection equipment may not start normally when it is turned on, causing the production line to stagnate and affecting production efficiency.
Possible causes: The reason for the failure to start may be equipment power supply problems, power switch damage, startup program errors, software system failures, etc.
Solution: First check whether the power plug and power cord are connected normally, and confirm whether the power switch is damaged. Check whether the startup program of the equipment is set correctly, and restart the equipment or restore the factory settings if necessary. If the problem persists, contact the equipment supplier for repair.
Decrease in detection accuracy
Fault description: After the equipment has been used for a period of time, the detection accuracy may decrease, which is manifested as the inability to accurately identify foreign objects or the frequency of false alarms increases.
Possible causes: The decrease in detection accuracy may be caused by factors such as aging of the X-ray source, failure of the detector, accumulation of stains on the surface of the equipment, changes in the detection environment, etc.
Solution: Regularly check and clean the surface of the equipment to ensure that there is no dust, oil or other substances that affect the image quality. If the X-ray source is aged or the detector is damaged, it needs to be replaced. Also check whether the calibration of the equipment is normal and recalibrate the equipment as needed.
Incomplete foreign object detection
Fault description: During use, the equipment may fail to detect some foreign objects, resulting in some harmful foreign objects not being detected.
Possible causes: Possible reasons include insufficient X-ray source power, insufficient detector resolution, and food packaging affecting X-ray penetration.
Solution: Increase the power of the X-ray source to enhance the detection capability of foreign objects. If the detector resolution is insufficient, it is recommended to replace it with a higher resolution detector. In addition, regularly check whether the equipment has insufficient penetration caused by uneven food packaging or sample morphology, and take appropriate treatment measures.
Frequent equipment alarms
Fault description: The equipment frequently alarms during the inspection process, usually false alarms or invalid alarms, causing unnecessary downtime and production line delays.
Possible causes: The sensitivity setting of the equipment is too high, changes in ambient temperature and humidity, machine vibration, equipment damage, etc. may cause frequent alarms.
Solution: Adjust the sensitivity setting of the equipment to avoid false alarms caused by excessive sensitivity. In the equipment installation area, avoid excessive environmental changes and ensure that the equipment is installed in a stable place to avoid vibration affecting the operation of the equipment.
The equipment cannot connect to the network or system
Fault description: Modern X-ray food inspection equipment usually needs to be connected to the production management system or network system to record, store or analyze the inspection data. If the equipment cannot connect to the network or system normally, data cannot be transmitted or lost.
Possible causes: The network interface of the equipment is faulty, the network connection problem, the software system configuration error, etc.
Solution: Check whether the connection between the equipment and the network is normal, and ensure that the network cable is not damaged or loose. Check whether the network settings of the equipment are correct, such as whether the IP address configuration is incorrect. If there is a problem with the device software system, the software may need to be updated or reinstalled.
X-ray source does not work properly
Fault description: The failure of the X-ray source to work properly is an important factor affecting the normal operation of the equipment. If the X-ray source cannot emit X-rays, effective detection will not be possible.
Possible causes: X-ray source damage, power supply problem, control circuit failure, etc.
Solution: Check whether the power supply is normal and ensure that the power supply voltage meets the requirements. If the power supply is normal, you can check the status of the X-ray source to see if it is aging or damaged. If necessary, the X-ray source needs to be replaced.
The equipment makes abnormal noise during operation
Fault description: X-ray food inspection equipment makes abnormal noise during operation, which may usually be caused by mechanical failure or loose parts inside the equipment.
Possible causes: Failure of motors, fans, transmission systems and other components inside the equipment, or loose parts inside the equipment.
Solution: Check all moving and fixed parts of the equipment to ensure that they are not loose or damaged. In particular, components such as fans and motors may need to be cleaned or lubricated regularly to ensure smooth operation. If the noise persists, further inspection or replacement of components is recommended.
2. Fault prevention and maintenance
Regular maintenance and cleaning: In order to maintain the stability of the equipment and long-term good detection performance, regular maintenance and cleaning are essential. Regularly check the condition of the equipment surface, detector, X-ray source and other components, and clean up dust or stains.
Equipment calibration: After a period of use, the equipment may deviate due to changes in the working environment or aging of internal components. Regular calibration of the equipment can ensure the accuracy of the test results.
Operator training: Ensure that the operator is familiar with the use and maintenance of the equipment and can make timely adjustments or report faults when problems are found. This helps to extend the service life of the equipment and reduce the frequency of faults.
Preparation of spare equipment: During peak production periods, once the equipment fails, production may stagnate. Enterprises can consider preparing spare equipment or keeping in close contact with equipment suppliers to ensure that faults are resolved in a timely manner.
X-ray food testing equipment is an important tool to ensure food safety, but various faults are inevitable in long-term use.
