Food X-Ray Inspection System for Canned Foreign Body Detection

In the food and beverage industry, metal packaging is widely used. Metal cans have excellent airtightness, combined with advanced packaging technology, can lock the freshness and nutrition of ingredients, and have a longer shelf life. In order to ensure food safety, the canned food production line is equipped with food X-ray inspection system for quality inspection, which can accurately detect unqualified products containing foreign objects such as metal, glass, stones, bone residue and high-density hard plastic, and automatically reject them.

#1 Customer Needs
Detect metal, glass, stone, hard plastic and other foreign objects in metal cans.
#2 Challenge
There are following difficulties in testing metal canned food:
Metal cans have a strong signal under X-ray irradiation, and at the same time, strong interference signals will be generated on the side wall, top tab, and bottom, which will affect the detection accuracy of food X-ray machines for foreign objects;
The bulging bottom of the tank may cause missed detection of foreign objects due to the limited irradiation angle;
If there are air bubbles in the liquid in the tank, it may reduce the detection accuracy of glass and stone foreign objects;
If the production line is fast, under the premise of accurately setting the removal time, it is necessary to ensure the ability to continuously remove unqualified products;
While rejecting, the cans cannot be dropped or damaged, and the removal time is set precisely.
