Drying Temperature Settings

Selecting the correct Dryer plenum temperature is a balance between capacity, grain quality, efficiency, safety, and cooling. The ideal drying temperature will vary depending on what is most important to you.

• Capacity – higher temperature increases capacity
• Efficiency – higher temperature increases efficiency (less fuel per pound of water removed)
• Quality – lower temperature increases grain quality
• Safety – lower temperature can reduce risk of dryer fires in adverse conditions.
• Cooling – lower plenum temperature can improve grain cooling capacity in low moisture removal drying.

When set to a Capacity/Quality default value of 5/5, the QUANTUM® will automatically set the drying temperature (in AUTOMATIC mode, based on incoming grain moistures), to balance capacity and quality factors. The QUANTUM® will reduce the plenum temperature as the incoming grain moisture drops. The Plenum Temperature Limit should be adjusted as shown in the chart below. This is the maximum automatic drying temperature used in the wettest grain conditions. The plenum temperature will also automatically be reduced to control moisture if the unload rate limit is reached.
