All moisture control systems that are based off of grain temperature are set up and function the same way. Once the plenum temperature has been established and the dryer is ready to start discharging, the discharge system must be in “manual” mode. Observe the moisture content of the discharging grain. If the grain is too wet, manually slow down the discharge rate. If the grain is too dry, manually increase the discharge rate. Repeat this process until the grain is being discharged at the desired moisture content for several hours. At this point, observe what the mid-grain temperature reading on the HMI is. Enter this number for the mid-grain set point on the HMI. Switch from Manual to TruDry.
It is important to maintain the same plenum temperature as you are going through this process. Remember to allow enough time to see the results of changes made to the discharge system. With all systems, the biggest requirement is patience.
Learn to record what discharge speeds work with different moisture contents, both incoming and discharge and different plenum temperatures. This information can be used in the future to shorted the set up time when establishing the moisture of the discharge.
