Overview and Challenges
1. Overview
To prevent condensation in silo trailers and thereby reduce the risk of bacterial and germ growth, Ants Technology & Consulting developed an innovative air drying solution that improves the air quality inside the trailer. The project was implemented in cooperation with Van den Bosch Transport B.V. in the Netherlands.
2. Challenge of the Customer
Moisture inside silo trailers can lead to condensation, creating favorable conditions for bacterial and germ growth. Residual moisture remaining after cleaning can also cause product residues to adhere to the silo walls, affecting hygiene and product quality.
To address these challenges, the customer required a reliable solution to continuously remove moisture and monitor air quality inside the trailer. In addition, accurate measurement of relative humidity and pressure dew point was needed to verify system performance and ensure consistently dry operating conditions.
3. Solution and Implementation
The air dryer is equipped with an activated carbon filter so that the incoming air is filtered. As a result, the air is of better quality than the outside air that is still present in the trailer due to the charging process.
The system draws in outside air, filters and dries it and blows it into the trailer. The unfiltered and possibly humid air in the trailer is discharged. This optimizes the air quality in the trailer and prevents condensation. Another advantage is that the risk of residual charges and the risk of bacterial and/or germ growth is greatly reduced.
Since the beginning of 2021, a semi-trailer has been equipped with the dryer/filter system mentioned above. Great importance was attached to hygiene and food safety during construction, e.g. the avoidance of protruding parts and bumps and the use of food-safe materials.
SUTO iTEC Dew Point Monitoring
An essential part of the system is the measurement and storage of data on the relative humidity and the pressure dew point. The clean, dry air that is blown into the silo and the moist air that is blown out of the silo is monitored by two SUTO iTEC S217 OEM Compact Dew Point Transmitter connected to the SUTO iTEC S331 Data Logger.
4. Results
The permanent removal of moisture from the silo has led to:
Dry Storage
Continuous drying and dew point monitoring maintained a dry environment inside the silo trailer, helping prevent condensation on internal surfaces.
Cleaner Silo
Residual moisture was removed after cleaning, helping keep the silo walls cleaner. As a result, product residues became rare or non-existent during operation.
Faster Unloading
Lower moisture levels improved product flowability, helping reduce discharge time and improve unloading efficiency.
Safer Transport
Lower moisture levels reduced the risk of bacterial and germ growth while helping maintain consistent product quality throughout transportation.
5. Conclusion
Maintaining dry and clean air inside a silo trailer plays a key role in protecting product quality during transportation. In addition, the combination of air drying and dew point monitoring enabled continuous control of air quality conditions while supporting high hygiene standards. As a result, the project created a sustainable foundation for reliable product transport and long-term operational performance.
6. Products in Use
The following SUTO iTEC solutions were used to measure and record dew point data, helping ensure dry and condensation-free conditions inside the silo trailer.
