2/3-1/3 Split or 50/50 Split

• Sukup Two-Fan Axial Dryers are available in two different fan configurations, 2/3-1/3 Split, or 50/50 Split
• 2/3-1/3 Split dryers are the more popular and economic style; they are easy to recognize because the top fan is always larger diameter than the bottom fan
• When running in heat/cool mode, 2/3 of the dryer is heating or drying grain and the bottom 1/3 is cooling; grain is typically approximately 20°-30°F above ambient temperature
• 50/50 Split dryers have two fans of the same size and can also run in full-heat or heat/cool mode
• These dryers are typically purchased to run in full-heat mode and get a little more airflow, and as a result, higher capacities, than a single fan dryer
• When running in heat/cool mode, they will discharge grain very near ambient temperature, but they will have less capacity than a 2/3-1/3 split because only half of the dryer is heating while the other half cools

Quad Metering Rolls

• Sukup's exclusive, patented Quad Metering Roll System (U.S. Patent #5,992,044) is standard on all Sukup Portable Grain Dryers
• By using two metering rolls on each dryer column, Sukup is able to pull grain down the drying columns at different speeds. The inner, hotter layer of grain is pulled down the column faster than the cooler, outer layer. The process produces more even moisture content of the dried grain, minimizes damage, and maintains higher test weights and overall quality.
• They reduce moisture variation and maintain grain quality without blocking airflow or creating spots for debris to accumulate
• The Sukup Quad Metering Roll System received an AE50 Award from the American Society of Agricultural and Biological Engineers

Electronic Mod-Valve

• Electronic modulating valve heater controls provide computer-controlled gas flow to maintain plenum temperature set by the operator
• This system is much more fuel efficient than on-off or high-low controls
• Plenum temperature can be easily adjusted from the control box

High Grain Column Holding Capacity

• Sukup cross-flow dryers have the widest grain columns available at 14 inches; wider grain columns allows for more grain in process, promoting higher grain quality and fuel efficiency when compared to narrower grain columns

Fans and Heaters

• Axial fan dryers are low-speed fans - 1750 RPM
• Low-speed axial fans are quieter than traditional axial fans used for in-bin drying and aeration because they run at half the speed
• Sukup fans are well-known within the agricultural industry for their high airflow, efficient operation and excellent reliability
