Bringing grain dryers into the 21st century

A smart grain dryer system lets farmers control the dryer from a distance and uses machine learning to make the crop drying process more energy efficient.

Introduction

Many grain dryers that farmers use today were built 10-20 years ago. While these older systems generally perform well, they lack the efficiency and benefits of modern technology.

By digitizing these dryers at a low cost, it is possible to significantly reduce drying expenses with only a small financial investment.

We have developed a technology that collects temperature data from the dryer and uses machine learning model to analyze drying cycles. The model accurately predicts when each batch will be ready, which helps save energy and provides farmers precision.

Remote control

In addition to monitoring what is happening in the dryer, the control system allows the operator to control the dryer from a mobile device.

Resource efficient grain drying:

  • Saves energy, including fuel, gas and electricity.
  • Reduces the farmer’s workload.
  • Optimizes the drying process.
  • Provides customized solution, as the machine learning model uses information from previous drying cycles to become more accurate.

In 2024, data was collected from five Estonian batch dryers, two Latvian batch dryers, the KEVILI Rõngu terminal dryer, and two METK seed dryers.
