In addition to the single and dual fan and heater grain dryers, Sukup also offers double and triple stack grain dryers. These units are available in 2, 3, 4, or 6 fan configurations to meet your drying needs. Sukup Stacked Grain Dryers have all of the outstanding features of our Single and Split-Plenum 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


  • 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

Optional Accessory Equipment

  • An Ethernet cable connects the QuadraTouch Pro™ control box to the dryer; 50', 100', 150', or 200' lengths available
  • Support legs available in 36", 48", or 60" lengths
  • Static Discharge Moisture Sampler catches a sample of discharged grain, test the moisture, and releases it, making it more accurate than testing moving grain
  • Lift brackets are bolted to the top of the dryer for use as lift points if the dryer is to be picked up by a crane
  • GSM modem sends a text message to a pre-programmed number in the event of a dryer shut-down. You can also text the dryer and it will reply with current operating status. Adjustments such as changing plenum temp, grain moisture set-point, manual unload speed, or shutting down the dryer can also be made from your cell phone. Works off of GSM cell phone signal.
  • MySukup Remote Web Access allows you to view dryer performance on a device (phone, tablet, computer) and change dryer settings via an internet connection from a Ethernet cable; dryer cannot be started remotely
  • Discharge extensions for unload auger are available up to 10 ft
  • Service catwalk is located at the top of the dryer by the wet bin, one side only
  • Side clean-off catwalk is located on the vertical portion of the outer screens, allowing you to safely clean the vertical screens and the top angled screen; side clean-off catwalk goes around both sides and the rear of the dryer
  • Canvas fan inlet cover used to keep the fan blades from free-wheeling and also to keep debris out of the dryer
  • Auxiliary motor controls - kits for fill or take-away equipment. 5, 7.5, 10, and 15 HP kits available
  • Column temperature sensor allows you to dry based on grain temperature
  • Stainless steel outer screens instead of standard galvanized screens
  • Stainless steel outer hardware instead of standard plated hardware
  • Noise Suppression Kits quiets the axial fans. Engineered noise absorbing panels are used to build an enclosure around the fan without reducing airflow.
Product Features
  • QuadraTouch Pro™ Controls with S.M.A.R.T. Loop™ Technology
  • Higher Capacity and Flexibility with Short-Fill Height
  • Available with Axial, Centrifugal or Hybrid Fan Combinations
