Maximise oil recovery from seed meals and slurries; continuous, energy-efficient decanters engineered for reliable seed oil production.

  • In seed oil extraction, the post-press slurry and wash water often contain valuable residual oil, solids, and moisture.
  • Conventional separation methods like settling tanks or belt presses deliver lower recovery rates, higher oil loss in cake and effluent, and frequent maintenance due to fouling.
  • Producers need durable decanter centrifuges that efficiently manage high solids, variable feed conditions, and abrasive materials; while maintaining low energy consumption and stable uptime.

Our Solution:

  • 4B Automation & 4B Systems delivers Alfa Laval decanter centrifuge systems tailored for seed oil applications.
  • Using Alfa Laval’s PONX (2-phase) and CONX (3-phase) decanter ranges, these systems are designed to separate oil, solids, and water phases efficiently with minimal energy input.
  • Our decanters are optimised for handling high-solids feed streams and variable conditions common in seed processing, such as soybean, sunflower, or canola oil production.
  • With our integration, automation, and service expertise, your plant benefits from higher yield, improved product quality, and reduced downtime.
