Sukup Stacked Dryers

Axial Fan Stacked Dryers

• Axial fan stacked dryers can run in full heat or heat/pressure-cool mode
• Easily switch from full heat to heat/cool mode with just a touch of a button on the QuadraTouch Pro™ controls

Centrifugal Stacked Dryers

• Centrifugal Stacked dryers use vacuum-cooling which can be 20-30% more fuel efficient than pressure-cooling
• Can run either full heat or heat/vacuum-cool
• Centrifugal fans are quieter than axial fans and perform better in the higher static pressure conditions that exist with vacuum-cooling when drying small grains

Hybrid Stacked Dryers

• The hybrid dryer is a more economical way to reap the benefits of the full heat/vacuum cool dryer configuration
• Hybrid Dryers use an axial fan on the top module and a centrifugal fan on the bottom
• The top module is equipped with a direct drive axial fan that doesn't require a belt
• Axial fans put out more airflow than centrifugal fans at low static pressure, so you use less horsepower to get the same airflow
• The bottom module is equipped with a centrifugal fan which allows you to vacuum-cool

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
• Reduces 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

HIGH GRAIN COLUMN HOLDING CAPACITY

• Sukup Crossflow 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

Fan and Heater Features

• Sukup stacked dryers are powered by either low-speed axial fans or centrifugal fans or a combination of both
• Axial Fans:
  • 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
• Centrifugal Fans:
  • Double inlet style
  • Belt driven
  • Capable of maintaining airflow at higher static pressure as seen with vacuum-cooling
  • Extremely quiet
• Heaters:
  • Line burner style
  • Very fuel efficient with low emissions
  • Wide temperature range allows for a lower drying temperature without changing any parts

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

Full-Heat or Vacuum Cool Drying

• Sukup Centrifugal and Hybrid Stacked Dryers allow you the flexibility to operate in full-heat or vacuum-cool mode
• Top module always operates in full-heat mode
• Bottom module can operate either in full-heat or pressure heat/vacuum-cool mode
• Panels within the plenum area are easily removed or replaced to switch between modes
• Adjustable air louvers are used to control airflow for different drying modes; louvers open completely for full-heat drying and louver openings are variable to adjust output grain temperature during pressure heat/vacuum-cool drying
