The soybeans from storage may contain up to 2% foreign material. The purpose of the weighing and cleaning process is to get an accurate inventory of the material being sent through the seed preparation process and to the remove as much foreign material as possible.


  • The advantages of the Desmet Ballestra Cleaning and Weighing process are as follows:
  • Provides uniform throughput control and regulation
  • Reduces capital cost, operating cost, and maintenance cost with vertical layout minimizing the number of material handling conveyors and elevators
  • Maximizes uptime with self-cleaning magnet
  • Reduces maintenance cost as magnet has no rotating parts and is fabricated with abrasion resistant material
  • Reduces potential fire hazard in downstream equipment by removing light foreign material in an air aspirator
  • Reduces maintenance cost with aspirator seed contact surfaces constructed of abrasion resistant material
  • Operator friendly as aspirator is located on ground level for easy access
