Efficient soybean production and storage require close attention to moisture, a factor that directly affects the quality and value of the final product. In this context, dielectric measurement stands out as the solution for precise, real-time soybean moisture control.
Why moisture measurement matters in soybean production
The right moisture content is vital for grain quality and shelf life, and it directly affects processes such as drying and storage.
Soybeans harvested too wet are more prone to fungal and bacterial growth, which compromises product quality and food safety. Soybeans that are too dry, on the other hand, lose weight and break more easily, which cuts into the producer’s profitability.
Dielectric measurement, a technology trend
Dielectric measurement has become the most reliable and accurate approach to monitoring soybean moisture in real time. The method measures the dielectric constant of the grain, which changes with water content, through the capacitance of a sensor. UmiGrain, from Marrari Automação, is a system that puts this technology to work.
Dielectric measurement offers several advantages, such as measuring the whole volume of grain that flows past the sensor, not just the surface, giving a fuller picture of each lot. It is also non-destructive: the grain is measured without damaging it and without removing anything from the production line, and the reading can be taken at any point in the process, from grain intake through the dryer to storage.


Benefits of real-time measurement with the dielectric method
- Accuracy and representativeness: dielectric measurement covers the whole volume of grain passing the sensor and provides more accurate, representative data than methods that look only at the surface or at small samples. This avoids internal variations that hurt product quality and gives you a true picture of the moisture in the entire load.
- Continuous monitoring: real-time measurement gives a dynamic view of moisture and allows immediate adjustments to any variation. This is especially important during drying, where precise control prevents over-drying and under-dried grain.
- Efficient drying and storage: with real-time dielectric measurement, producers can optimize drying and storage and keep soybeans in the ideal conditions to preserve their quality.
The solution for real-time soybean moisture measurement
Marrari Automação’s UmiGrain is a complete solution for measuring and controlling soybean moisture in real time. The system combines dielectric measurement with real-time monitoring and automatic control features.
By integrating UmiGrain into their processes, soybean producers can optimize drying, store grain in ideal conditions and preserve the quality of the final product. The system also sends automatic alerts on critical conditions, so the team can respond quickly to any unwanted change in moisture.
