In cooking oil processing, have you ever wondered why oil yield remains low even with advanced solvent extraction plant technology? The real issue often lies in the pretreatment process at the front end.
Pretreatment is the core step in a soybean oil production line, peanut oil processing plant, sunflower oil processing plant, and other cooking oil projects. Every stage—seed cleaning equipment, crushing machines, softening process, and flake pressing equipment—directly determines oil yield and energy consumption. Incomplete cleaning allows impurities to reduce extraction efficiency; uneven crushing and flaking trap oil inside seed cells; insufficient softening decreases permeability, leading to lower oil recovery. Pretreatment procss is the first critical step for achieving high oil yield in any cooking oil processing plant.
QIE GROUP specializes in manufacturing efficient cooking oil pretreatment equipment, energy-saving oil press machines, and intelligent cooking oil production lines.
