Seed Cleaning


Q-SAGE, Inc. 4x94-53-2+2 Precision Seed Cleaner


Each machine is engineered to the specific needs of the customer, resulting in an investment that is thoroughly utilised.

Optional 60" wide screens provide additional capacity above the competition at minimal cost.

All units feature high tolerance, quality screens and ball tray systems. These are custom made by the Quality Custom Screen Company, the leader in precision made screens and ball tray systems.

All Eccentric Components are CNC machined to a tight tolerance, resulting is a straight & true shake action of the screens.



Premier Grain's Length Graders utilze a single 17 or 23 inch diameter high density hardened cylinder. We use an environmentally and employee friendly carrbonitriding process to surface harden our cylinders to a minimum of 55 Rockwell C. Standard checks throughout the manufacturing process insure consistent quality and customer satisfaction. We at Premier Grain strive towards quality, product safety, and social obligations to our employees, our customers, and the environment.


Material is fed into a rotating cylinder, all material shorter in length than the indent pocket is lifted into a conveyor trough that runs through the center of the cylinder and is then discharged out the end. Material that is not lifted is conveyed out along the bottom of the cylinder to the discharge outlet at the same end.

Stratification on an Oliver is unique. Proper lifting is provided by an air system specially designed for particle concentration. Hi-Cap destoners feature Oliver's patented multiple fan, air supply system. Unlike our competition, Oliver engineers did not just go buy a fan off the shelf and attach it for airflow. Oliver engineers specifically designed our new fans for accurate weight separations using Computer Aided Design (CAD) technology. The operator can adjust each fan separately to allow precise control of the air. As a result, our fan design maintains the unique requirements necessary to separate particles that differ in density. Worldwide, Oliver's fan performance is proven to be the benchmark for separation efficiency.


All of our machines include the following:

  • Rub, De-awn, & Polish a Variety of Seed to Increase their Test Weight & Value Heavy Wall Drum Design for Superior Longevity
  • Hardened Steel Paddles
  • Industry Standard 15° Angle on Paddles to Rub & Assist with Product Flow TEFC, NEMA Premium Efficient Motors; X-Proof Available
  • Dust Hood at Discharge of Machine for Containment
  • Optional VFD (Variable Frequency Drive) for Easy RPM Adjustment

The Maxi-Cap Platinum Series

The Oliver Maxi-Cap Platinum series brings the safety, simplicity and efficiencyof integrated control to one of the most reliable gravity separators ever made. The Platinum is an evolved Maxi-Cap with the addition of a Programmable Logic Controller (PLC) and touch screen, which provide a central interface for operating control over all adjustment parameters. These programmable automation controls provide simplified operation, reduce yield losses due to human error and can integrate Oliver machines into automated processing facilities. Continuous control over feed rates, pinpoint air ow and 4-way deck tilt combine for the most precise separation and highest quality end product possible.

Precision Operator Control

By combining the control over all parameters into a centralized graphic interface, Oliver has simplied training, setup and operation. A 6-inch touch screen governs air flow, eccentric vibration, side tilt, end raise and feed rate. A power-assisted joystick provides 4-way control over deck angle. Together, they make adjustment instantaneous and eliminate the need for the operator to move to different parts of the machine to make adjustments.

Programmable Memory

The Allen-Bradley PLC stores and retrieves parameter settings for up to 20 different material processing “recipes” plus an automated machine cleanout routine. Recipes can be memorized during actual operation or downloaded from the manufacturer from among dozens in popular use. Memorized settings:

  • Provide outstanding consistency regardless of the training or experience level of the operator
  • Ensure more uniform quality in the finished product
  • Reduce the loss of acceptable material

Pre-Wired Plant Intergation

Pre-wiring means the machine can be installed with a single electrical connection to a power source. In addition, integration with plant automation is accomplished with a single ethernet connection to the central control network. For safety and convenient maintenance, all memory and control automation is housed together in a dust-tight and splash-proof NEMA 12 electrical cabinet. All electronics come with a 3-year warranty when factory installed, versus the industry standard of 1 year.

  • Factory wiring provides simplified installation.
  • Single network connection simplifies plant process integration.
  • Single point connections minimize installation time, e ort and speed of return on investment.

In addition, all electrical components are UL listed, meet or exceed national electrical code and with the full backing of the Rockwell Technical Support Team.
