Corn dryer DHD

stationary

The PETKUS Corn Cob Dryer DHD is used for the energy-efficient drying of husked corncobs at harvest moisture levels. In the Double-Pass Reverse Process all drying chambers are connected with each other by a central air duct system. The hot air is generated centrally by four burners/fans. In the first pass the drying air flows through the air ducts into the top of the drying chamber where it gives pre-dried product its final drying pass. The slightly saturated air exits at the bottom of this chamber and passes through previously undried corn in a second chamber from bottom to top and the cool saturated air exits outside as exhaust air. The double pass system allows for highly efficient use of energy. Characteristics •Even and gentle drying by using upper and lower air infeed •Operation with gas or oil burner as well as heat exchanger possible •Number and size of drying chambers according to customer requirements •The complete system is centrally controlled by software •Complete temperature monitoring in the system with automatic shutdown if the alarm temperature is exceeded •Improved energy efficiency due to bypass flaps (optional)
