Drying hay under controlled conditions is the key to producing quality forage for ruminants. For long-term storage, feed should not contain more than 15 % water. The current drying device only allows the fan to be turned on and off without information about the humidity of the air and feed. That is why it often happens that the forage is aerated with air that is more humid than the moisture content of the forage.
The task included a technological upgrade of the existing drying device to enable automatic operation under ideal conditions. We have developed a system that controls the fan with the help of temperature and relative humidity sensors and displays the drying parameters to the user. This increased the efficiency of the drying device and eliminated the possibility of unwanted humidity input.
