Real-time moisture measurement has reached the heart of farming in Mato Grosso do Sul, Brazil, and has become a success story that is redefining efficiency standards in the industry. Acquiring UmiGrain, an in-line grain moisture sensor, proved to be a game changer during the second corn crop (safrinha).
UmiGrain in action: technology built into the process
Since it was installed in early August 2023, UmiGrain has been running nonstop and is fully integrated into the processes. Placed at the outlet of the pre-cleaning machine, the sensor measures in real time, removing the need for constant sampling and diverting the grain flow.


Real-time moisture measurement vs. traditional sampling methods
UmiGrain’s main strength is its moisture measurement accuracy, delivering reliable results compared with traditional sampling methods. This simplifies operation, lets operators focus on control and brings notable efficiency to grain dryer automation systems.
The moisture reading, shown on the equipment’s human-machine interface (HMI), is integrated into the automation system through communication protocols. This data exchange lets the plant adjust drying parameters automatically, optimizing the process and reaching the desired final moisture accurately.

Savings and efficiency: the financial impact of UmiGrain
Implementing UmiGrain simplified daily operation and also brought significant economic benefits. In-line moisture measurement proved crucial to dryer efficiency, preventing over-drying, which causes mass loss, and inadequate moisture, which adds warehouse aeration costs and even fire risks.
Versatility: UmiGrain at many points of the operation
UmiGrain is highly versatile. Its robustness and ease of operation allow it to be used at many points, from intake to truck loading: at dryer inlets or outlets and when loading silos or warehouses, always as a reliable and efficient solution.
The company using the system has not only embraced the technology but also opened new horizons for regional agriculture. UmiGrain is a tangible expression of the innovation driving agribusiness in Mato Grosso do Sul.
