Potato Chip X-ray Machine Case Study

For the food processing industry, especially for high-speed, fragile products like bagged potato chips with various packaging materials (often containing aluminum foil), X-ray machines are the "last line of defense" to ensure food safety.

The core challenge

1. To prevent moisture and oxidation, potato chip packaging often uses aluminum foil. Traditional metal detectors cannot recognize aluminum foil, resulting in false alarms and missed alarms, and they are completely unable to detect non-metallic foreign objects such as stones and glass .

2. Material overlap interference: Potato chips are randomly stacked inside the bag with varying thicknesses. The "background noise" generated by a regular X-ray machine can easily trigger an alarm, resulting in a high rejection rate.

The Solution

Our company's food-grade X-Ray foreign object detection system is specifically designed to handle puffed foods with complex ingredients.

1. Full material coverage testing

By utilizing the differences in X-ray absorption rates of different substances, it can not only identify metals (stainless steel, metals), but also accurately detect high-risk foreign objects such as ore fragments, flat/glass plates, and high-density rubber inside low-density packaging.

2. Multi-level intelligent algorithms

Automatic masking technology: The algorithm automatically identifies and masks interference from the sealing area and inflation edge of the packaging bag, focusing on the detection of the contents.

Dynamic threshold compensation: In response to the uneven thickness of potato chip stacks, the system automatically adjusts the detection benchmark and intelligently identifies and reduces the false rejection rate.

3. Linked high-speed rejection

The system is equipped with a precision air-blowing or push-plate rejection mechanism. Once a foreign object is detected, the system calculates the conveyor belt displacement to ensure that the bag of problematic products is accurately blown off the production line at high speed.

Technological Advantages (Competitive Edge)

Customer Value (Impact)

Brand protection: Effectively avoids public relations crises and recall losses caused by end-consumer complaints (such as the "gritty" incident).

Improved production efficiency: The equipment supports a fully automatic learning mode. When changing product types (such as from large packaging to shareable packaging), you only need to scan the new sample with one click, without the need for tedious debugging.

Compliance and market access: Compliant with international food safety system requirements such as CE and FDA , helping products to smoothly enter high-end supermarkets and overseas markets.
