How to choose X-ray inspection equipment for canned food?

In the field of modern food processing, canned food occupies an important position in the global market because of its easy storage, transportation and consumption. However, with the increasing standards for food safety, how to ensure that canned food does not contain any foreign matter before leaving the factory has become a severe challenge for manufacturers. X-ray detection equipment has become an important means of canned food safety testing due to its advantages of non-contact, non-destructive, and penetrating metal packaging. So, when purchasing X-ray detection equipment, what aspects should be considered to ensure the adaptability and cost-effectiveness of the equipment? This article will give you a comprehensive analysis.

1. Why must canned food be inspected using X-rays?

Before choosing equipment, we must first clarify "why canned food is more suitable for X-rays rather than other detection methods."

1.1 Metal packaging limits traditional detection methods

Canned foods usually use metal materials such as tinplate and aluminum as outer packaging. This material itself interferes with traditional metal detectors and is very likely to cause misjudgment or missed judgments. X-ray technology can penetrate metal and detect whether there are foreign objects, bones, glass fragments, plastic fragments, metal chips and other unexpected components inside.

1.2 The contents are easily deformed after high-temperature sterilization

Canned food usually needs high-temperature and high-pressure sterilization after packaging. During the process, the food may deform or expand, affecting visual inspection. X-ray imaging will not be affected by appearance deformation and is more stable and reliable.

2. What are the core factors to consider when selecting X-ray inspection equipment for canned food?

When selecting, it is not "expensive is good", but it should be comprehensively judged based on application scenarios, product characteristics, production line requirements, detection accuracy and other factors. The following aspects are the most critical parts of the selection process.

2.1 Detection accuracy and resolution

Different equipment has different detection accuracy. Some equipment can identify metal debris or glass slag below 0.2mm, while others can only identify large foreign particles above 1mm. It is recommended that food companies clarify the types of foreign objects and the minimum particle size they need to detect, and choose equipment with sufficient resolution.

2.2 Adapt to a variety of can sizes

There are many types of canned food on the market, ranging from small luncheon meat cans to large bean cans. Therefore, the equipment needs to support fast switching of inspection procedures for products of different sizes, support multi-product settings and fast adjustment.

2.3 Processing speed and production line docking capability

Generally, X-ray inspection equipment can reach an inspection speed of 100 to 400 cans per minute. The speed needs to match the rhythm of the production line to avoid forming a production line bottleneck. At the same time, it is also necessary to consider whether the equipment supports seamless docking with existing conveyor lines.

2.4 Inspection stability and false positive rate

X-ray inspection equipment should have a low false positive rate, especially when inspecting high-density meat cans or liquid foods. The equipment must be able to accurately distinguish between "normal density" and "abnormal foreign matter" inside the product.

2.5 Waterproof and dustproof level

The canned production environment is often humid, and some production lines even need to be flushed regularly. Therefore, the inspection equipment should at least reach the IP65 protection level to ensure long-term stable operation of the equipment.

3. Common Misunderstandings and Trap Avoidance Guide

3.1 Ignoring Product Density Differences

Some companies do not fully consider the density differences of different canned contents when purchasing. For example, the density of canned fruits and vegetables is very different from that of canned meat, which will result in the inability of the same equipment to accurately detect all types. Therefore, it is recommended to purchase an X-ray inspection system with automatic image learning and intelligent recognition algorithms.

3.2 Only look at the price and ignore after-sales service

X-ray equipment is a high-precision instrument. After long-term operation, calibration errors and light tube aging may occur. If the manufacturer does not provide timely after-sales service, it will seriously affect the stability of the production line. Therefore, it is necessary to choose a brand supplier that provides localized services or remote diagnostic support.

Correctly buying X-ray inspection equipment for canned food can not only greatly improve the level of product quality control, but also effectively reduce the risk of recall and brand loss. It is the only way for every food company to achieve "high-quality development".
