Food Inspection

Food Inspection
 

The use of X-ray technology is most familiar to people through its use in medical imaging. However, X-rays can also penetrate food products and allow the imaging of the internal features of the food to detect physical defects or contaminants without damaging the food product.
If you’ve been through security at the airport, you’ve probably seen X-ray systems in action. X-ray systems produce density images that are analyzed for irregularities by computers and people.
X-ray inspection is becoming increasingly necessary for checking the quality in the food industry.
Food applications are more complex than security at the airport. A typical application is the inspection for foreign objects in food. The size and type of anomalies being detected is more challenging and the speed of the inspection is much faster.
Because of this issue, manual inspection of these products is nearly impossible. Only by using X-ray technology, combined with dedicated software, can the search for foreign objects become possible.

Principle

The inspection is carried out by moving the object on a conveyor belt while scanning the object line by line with an X-ray camera. Our highly sensitive line scan camera can detect and visualize even the slightest variations in density of a large variety of product compositions quickly, objectively and reliably.
The X-ray transmission received by the line sensor is converted to electric signals. An image processing system converts the signals to X-ray transparent images and processes that image to detect contamination and defection of product.
