In-Line Monitoring of moisture distribution on products before packaging
Based on decades of expertise in thermal imaging inspection, Yoran Imaging delivers an innovative, in-line solution for the detection of pre-packaged product moisture distribution.
Proven technology
Based on Yoran Imaging’s award-winning thermal imaging technology and decades of inspection expertise.
Ongoing consistency
The process is continuously monitored to help ensure maintenance within pre-defined moisture parameters.
Seamless integration
All monitoring is done inline, without direct contact and without interfering with the line speed.
Deep data
Automatic generation of digital data for analysis and documentation of the process.
Scientific inspection
The system instantly converts a thermal image into moisture content level (%).
Instant alerts
As soon as the system detects a trend in moisture content, it alerts the operator.

H₂O molecules absorb IR energy
The thermal image of “dry” material is higher compared to “moist” material due to IR absorption effect.
The absorption effect is caused by vibration modes of the H2O molecules.
The system shows a high correlation between the thermal image and the measured moisture content.
It is so sensitive it can detect a 0.05% deviation in moisture, allowing for alerts in real-time.
Benefits vs. Traditional Inline NIR (Near Infra-Red) Spectroscopy:
- Thermal imaging sees the entire picture while spectroscopy focuses on a small region
- Thermal imaging can see process failures due to underheat/overheat of the product during the drying phase.
- Thermal imaging can see structure, size, distribution of the products and the distribution of the moisture.
- Thermal imaging doesn’t need illumination vs. the illuminating light needed in spectroscopy.
- Thermal imaging is intuitive vs. the non-intuitive analytical results of spectroscopy.
