Wear Resistance of Oil Press Working Components: How Quality Strainer Bars and Screw Sets Reduce Oil Processing Costs

In the process of mechanical oil extraction from sunflower, rapeseed, or soy seeds, the working components of presses experience enormous abrasive and barometric loads. Wear of the strainer bar edge of just 0.3–0.5 mm leads to the widening of strainer slots, solid fraction (meal dust) carryover into the oil, chamber pressure drop, and a sharp increase in residual oil content of the meal cake.

Machine-building enterprise D.ENERGY manufactures and supplies precision strainer bars and chambers for screw presses, as well as replacement screw sets and compression cones for most types of industrial oil-pressing units.

Why D.ENERGY components withstand high loads:

• Alloyed special-purpose steels: we use wear-resistant structural and tool steel alloys resistant to intensive abrasion and high temperatures (over 120 °C).

• Hardening technology: bulk or zone quenching with controlled tempering ensures working surface hardness to 58–62 HRC without the risk of brittle bar failure.

• Precision CNC milling: geometric accuracy of discharge channels excludes misalignment during strainer barrel assembly and ensures even oil discharge without plugging.

Besides serial products, D.ENERGY engineering department performs individual mechanical processing and wear-resistant carbide overlays per customer drawings or samples, allowing to extend the maintenance interval of the pressing shop to 35–40%.
