With the increasingly stringent food safety supervision, X-ray detection technology has become one of the important quality control methods in modern food production enterprises. Especially in the aquatic product processing industry, fish meat, canned fish, fish balls and other products often have fish bone residues, which not only affects the consumer experience, but also may bring safety hazards. As an efficient and accurate foreign body detection equipment, fish bone X-ray detection system is gradually being adopted by more and more companies. So, when purchasing a fish bone X-ray detection system, what parameters should companies focus on in order to choose a product that is both suitable for their own needs and cost-effective? This article will analyze the key parameters that need to be paid attention to when purchasing a fish bone X-ray detection system from multiple dimensions such as detection sensitivity, penetration, resolution, equipment size, conveying speed, degree of intelligence, environmental adaptability, maintenance cost, software function and security, to help companies make scientific decisions and avoid pitfalls.

1. Detection sensitivity

Sensitivity is one of the important indicators to measure the core performance of the X-ray detection system. The so-called sensitivity refers to the minimum fish bone size that the equipment can detect. The sensitivity requirements are different for different fish products and fish bone types. Generally speaking, fish bones have lower density, smaller thickness and weaker signal than foreign bodies such as metal and glass, so it is more difficult to detect.

Before purchasing, you should clarify:

The fish species of the test object and the common fish bone size;

The minimum detectable fish bone diameter or thickness of the equipment under the conditions of the product;

Whether it can meet the company's requirements for the fish bone residue rate (for example, some exports require control within 0.3mm).

Generally, the higher the sensitivity, the higher the price, but insufficient sensitivity may lead to missed detection and cause quality accidents. Therefore, the sensitivity needs to be reasonably selected in combination with its own product process and regulatory standards.

2. Penetration

Products such as fish meat, fish cakes, and canned fish vary greatly in shape and density, and some of them are even more than 100mm thick. If the equipment has insufficient penetration, the X-rays may not be able to fully penetrate the product, resulting in a blind spot or blurred image, thereby reducing the detection effect.

Penetration is mainly determined by the following factors:

The energy of the X-ray source (usually expressed in kilovolts kV, the higher the energy, the stronger the penetration);

The sensitivity and resolution of the detector;

The thickness, density and packaging material of the product itself.

It is recommended to confirm with the supplier whether the penetration ability of the equipment meets the requirements based on the thickness and density of your own products. At the same time, it should be noted that there is a certain trade-off between penetration and resolution. Blindly increasing the energy may damage the imaging accuracy.

3. Resolution

The resolution determines the system's imaging clarity and discrimination ability for tiny foreign objects. For fishbone detection, the higher the resolution, the easier it is to identify small and low-density fishbones.

Need to know:

The pixel size of the image (usually expressed in mm or µm);

The pixel matrix and sensitivity of the detector panel;

Whether high-definition imaging and image enhancement are supported.

High resolution helps detect smaller fishbones, but it may also mean slower detection speed or higher cost. Therefore, the fishbone size, production line speed and budget should be considered comprehensively to select the appropriate resolution.

4. Equipment size and installation space

The overall size and weight of the equipment directly affect installation and use. If the production line space is limited, the length, width and height of the installation area should be measured in advance, and ensure that there is enough space for the equipment body, conveyor belt and personnel operation.

In addition, it is also necessary to consider:

Whether the height of the conveyor belt matches the existing assembly line;

The length of the equipment inlet and outlet, whether there is enough buffer zone;

Whether it is easy to carry, disassemble and maintain.

A reasonable layout can reduce the cost of later transformation and improve production efficiency.

5. Detection speed (conveyance speed)

Enterprises with a fast production pace need to pay special attention to the detection speed. Generally speaking, the conveyance speed of X-ray detection equipment is measured in meters/minute or products/minute. Too slow speed may cause congestion on the production line and reduce production capacity, while too fast speed may affect the detection accuracy.

When purchasing, you should confirm:

The maximum detection speed of the equipment at high sensitivity;

Whether the speed adjustment range and adjustment are convenient;

Whether it supports simultaneous multi-channel detection (to improve processing capacity).

It is recommended to choose a model with a good balance of speed and sensitivity to meet the current and future production needs of the enterprise.

6. Degree of intelligence

Modern X-ray detection equipment is not just a "irradiation-display" process, but is also equipped with a variety of intelligent functions to improve detection efficiency and user experience.

Pay attention to the following points:

Whether it has automatic calibration and self-learning functions;

Whether it supports automatic identification, marking and removal of foreign objects;

Whether it can classify and record the test results and generate reports;

Whether it supports remote monitoring, remote maintenance and software upgrades.

Highly intelligent equipment can reduce human intervention, lower the operating threshold, and improve the management level.

7. Environmental adaptability

The fish processing environment is usually humid, low temperature, and even has ice water and salt spray, which puts higher requirements on the durability of the equipment. When purchasing, you should understand the equipment's protection level (such as IP level), operating temperature range, corrosion resistance and other indicators.

Specific attention:

Whether it is waterproof and dustproof;

Whether key components (such as circuits, X-ray sources) have protective designs;

Stability in humid, low temperature, and high salt environments.

Choosing a model suitable for the environment can effectively extend the life of the equipment and reduce the failure rate.

8. Maintenance cost and after-sales service

X-ray detection equipment is a high-precision electronic instrument, and maintenance and after-sales service are very important. You should know in advance:

Replacement cycle and cost of consumables (such as X-ray tubes, detectors, etc.);

Is it easy to clean and disinfect;

Whether the supplier provides timely technical support, spare parts and training;

Warranty policy and response time.

In the long run, maintenance costs and after-sales service quality directly affect the total cost of ownership and cannot be ignored.

9. Software Function

Fishbone detection does not only rely on hardware, but also powerful software algorithms. Good software can greatly improve detection accuracy and efficiency through algorithm optimization, image processing, deep learning and other means.

Key focus:

Whether it supports real-time image display, playback and analysis;

Whether it has the ability to automatically learn product features and reduce false alarms;

Whether it can record and export historical detection data;

Whether it has multi-language interface, permission management, operation log and other functions.

The advancement and ease of use of the software determine whether the equipment can adapt to the needs of enterprise development in the long run.

10. Safety

X-ray equipment is a controlled special equipment and must comply with relevant safety standards and regulations to avoid radiation hazards to operators and the environment.

When purchasing, you should ensure that:

It complies with local or international electromagnetic radiation safety standards;

It has complete shielding, interlocking and alarm devices;

Whether radiation detection reports and certificates are provided;

Whether there are complete safety operation guidelines and training services.

Safety is not only related to employee health, but also to the legal compliance risks of enterprises.

As an important quality control equipment in food processing enterprises, the performance of fishbone X-ray detection system directly affects the safety, qualification rate and market reputation of products. In the purchase process, key parameters such as detection sensitivity, penetration, resolution, speed, intelligence, environmental adaptability, etc. should be fully considered, and combined with the actual production situation and budget of the enterprise, comprehensive weighing and scientific decision-making should be made.
