DMC Stir-Ator

dmcWhy DMC’s Stir-Ator?
Double Auger Stir-Ator Only DMC’s Stir-Ator single, double or triple auger machines give you the most thorough, systematic time tested stirring pattern you can buy.

Choose a DMC Stir-Ator with one, two or three augers to fit 18 to 48 foot bins. Whether purchasing a new bin or updating present storage to drying, a Stir-Ator can cut drying time by 50% in a low temperature bin. A Stir-Ator can also help store grain and be used as a management tool for grain conditioning.

The Design III uses a spiral-stirring pattern that completely and evenly stirs the entire bin every stirring cycle.

Fifty (50%) percent of the grain in a bin is in the outside 1/3 of the bin. A DMC Design III provides the ONLY stirring pattern to spend more time stirring the outside of the bin rather than the center of the bin. The Design III also moves the outside auger closer to the bin wall than competitors’ machines.

DMC Triple Auger Stir-Ator

Triple Auger Stir-Ator A Design III Stir-Ator turns any drying bin into a self-contained drying and storage system. With a Stir-Ator in your bin, you have wet holding, drying and storage all in the same unit. The bin can be filled with the Stir-Ator running to stir the grain and insure that the maximum amount of drying air can be pushed through the grain to increase drying capacity. A complete bin full of grain can be dried in one filling with this method. While this method is not the fastest, it is very efficient and maintains the highest grain quality of all drying systems.

DMC Inside Look of Grain BinInside look of grain bin w/ Stir-AtorA Stir-Ator decreases static pressure by fluffing or loosening grain to allow maximum airflow. Grain is mixed so it dries faster, thus avoiding the problem of overdrying bottom layers of grain while the top layers are still wet. When all the grain is dry, a Design III Stir-Ator equipped bin can be used for storage. Periodic running of a Stir-Ator (with or without aeration) helps prevent grain spoilage and damage when storing over a long period of time.

Continuous-flow System

A Stir-Ator works well with an in-bin continuous-flow system to increase drying capacity. The dry grain is continuously removed from the bottom of the bin as it dries. The stirring augers should be cut off 30 inches above the floor to avoid disturbing the drying front. The grain above this zone (grain depths of up to 16 feet) is constantly being stirred, allowing greater airflow and heat to move upward through the wet grain to provide greater drying capacity and maximum efficiency.


The Red Giant for Larger Drying Bins

DMC Red GiantRed Giant Stir-Ator The Red Giant Stir-Ator is a 4 or 6 auger stirring machine designed for drying bins using high heat and large airflow. The extra augers provide the additional stirring required with high drying rates.

The Red Giant uses a roller chain, positive drive system to move the trolley in and out as the Stir-Ator moves around the bin to generate the familiar DMC spiral stirring pattern.

The trolley is designed to have the augers in the center of the bin rotate slower than the augers at the bin wall to avoid over stirring the grain in the center of the bin. The gentle stirring at the center of the bin makes the Red Giant an excellent choice for drying rice.

The Stir-Guard is a standard feature on the Red Giant.


Standard Features:
The Design III was engineered to require a minimum amount of maintenance and remains the most popular selling stirring machine ever built.

The following features are STANDARD with DMC’s Stir-Ators.

  • Graduated Pitch Augers
    Easier start ups, more flighting at bottom of auger where the most grain is stirred. More flighting to move more grain.
  • Rugged Drive

    A 3/16″ aircraft cable drives the machine, no reversing switches.
  • Disconnect Box
    A fused disconnect box to protect motors and your investment.
  • Safety Shut-Off

    The machine will shut down if the trolley gets in a bind position.
  • Fused Gear Motor
    Protects against electrical problems.
  • Sealed Bearings

    Low maintenance
  • One Mercury Switch

    DMC pioneered this feature and uses one switch to run the machine…experience speaks.
  • Gear Motor Ratio
    The “9 to 1” gear motor ratio makes DMC’s Stir-Ator the most aggressive machine money can buy.
