Sesotec has partnered with Khao Shong Group Co. in Thailand, to install its Raycon X-Ray inspection system to inspect coffee in metallic or metallized packaging materials.

The company was looking for alternative methods for contaminant detection for its ‘3 in 1’ blended coffee for consumers with busy lifestyles. 

Metal particles

The packs come in small convenient packages that can be taken anywhere in seven flavors; Super Rich, Espresso, Cappuccino, Condensed Milk, Mocha, Smooth and Creamy, and Caramel Macchiato.

In the production of coffee mix ‘3 in 1’ (instant coffee, milk powder and sugar) broken metal particles from processing machines could contaminate the product.

With a coffee mix in metallized packs it is difficult to detect such metal particles with conventional methods.

"Sesotec's X-Ray technology at present is the best technology to meet the high demands of our quality management​,” said Chana Chiralerspong, MD, Khao Shong Group Co.

The experience we have had in the meantime with Sesotec's customer service further confirmed our decision for the Raycon system​."

Sesotec, which supplies metal detectors, X-ray inspection systems and sorting systems is based in Schönberg, Germany

PVC, glass, stone

Its Raycon bulk product sorting systems can detect all contaminants due to their density, chemical composition, or mechanical dimensions and absorb radiation to a greater degree than the surrounding product, for example, metal, glass, ceramics and stone contaminants in food.

It can also detect some plastics, such as PVC or rubber.

Khao Shong Coffee was founded in 1959 when Chira Chiralerspong noticed that wild coffee beans were scattered on both sides of the road. He picked them up and found that they were coffee beans.

Through his experience of coffee production in Indonesia, he collected the wild coffee beans from the park and roasted them in different ways until he found the perfect way to make a cup of coffee with rich aroma and fine taste.

He launched Khao Shong Coffee to the market in 1962.
