In-line density measurement of soup blocks significantly increases yield

In order to avoid any underweight of the soup cubes they are usually produced with a slight overweight. Prior to applying microwave technology they producer overfilled the cubes by up to 5%. With a correlation of 0.998 compared to a balance but with a speed up 20.000 measurements per second we are monitoring the weight and could feed back the information to the pressing machine. By checking the soup cubes and automatically controlling the pressing process with our microwave technology the target weight can be achieved with a higher accuracy of 0.25% (+/- 10 mg instead of +/- 25 mg before).
