Stacked Dryers

From

0

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 Stack Grain Dryers have all of the outstanding features of our single and dual plenum dryers. In addition, they have our exclusive, patented Grain Cross-Over System,

Axial Fan Stacked Dryers

Axial fan stacked dryers can run in full heat or heat/pressure cool mode. You can easily switch from full heat to heat/cool mode with just a touch of a button on the QuadraTouchTM controls.

Centrifugal Stacked Dryers

Centrifugal stacked dryers use vaccum cooling. They can run either full heat or heat/ vaccum cool. Centrifugal fans are quieter than axial fans and perform better in the higher static pressure conditions that exist with vacuum cooling.

Hybrid Stacked Dryers

Hybrid Dryers use an axial fan on the top module and a centrifugal fan on the bottom. The hybrid dryer is a more economical way to reap the benefits of the full heat - vacuum cool dryer configuration. The top module is equipped with an axial fan and always runs in full heat, 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.

Patented Grain Cross-OverTM System

Sukup developed the patented Grain Cross-OverTM System to help eliminate overdrying and balance the moisture content of dried grain in a stacked dryer configuration.

Innovative system switches grain from one side of the dryer to the other as it passes from module to module.

  • Balances exposure of each portion of the grain to adverse weather conditions, such as cold wind and/or rain.
  • Also switches the grain from the inside of the column to the outside.
  •  Prevents grain from overdrying and gives more consistent moisture content.
  • Reduces variation inmoisture content between the inner and outer portions of the columns, as well as between the two sides of the dryer.

QuadraTouch

The QuadraTouchTM is the simple-to-use touch screen control system used on all Sukup Grain Dryers. 

Extremely user-friendly menu-driven system - for those who are not tech-savvy

Designed to eliminate around-the clock monitoring and increase productivity and efficiency.

Advanced algorithms and calculus are used to increase dryer efficiency and reduce large swings in temperature and discharge moisture.

PLC-based system is built to withstand harsh environments.

Can be remotely-located up to 200 ft. away from dryer

Received an AE50 award from the American Society of Agricultural and Biological Engineers for outstanding innovations in agriculture.

Quad Metering Rolls

Sukup's exclusive, patented Quad Metering Roll System is standard on all Sukup Portable Grain Dryers.

Reduces moisture variation and maintains grain quality without blocking airflow or creating spots for debris to accumulate.

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.

Metering roll speed varies depending upon the actual moisture content of the discharged grain.

The Sukup Quad Metering Roll System received an AE50 Award from the American Society of Agricultural and Biological Engineers.

Automatic Moisture Control

Sukup was the first company to make true moisture sensing standard on its dryers.

Sensing the moisture content, rather than temperature, gives a more accurate measure of drying progress and results in more consistent final moisture content.

Moisture content information is collected from the sensor located in the discharge tube.

Fans & 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

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 Dryers are available in a double-stack configuration that allows 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.
  • Louver openings are variable to adjust output grain temperature during pressure heat/vacuum cool drying.
