In copra oil production, pretreatment is not a routine preliminary step, but a core process that directly determines oil yield, equipment service life, and final oil stability. 👉(Why pretreatment equipment determines edible oil quality)
Drawing on decades of edible oil engineering experience, QIE GROUP provides a systematic and controllable pretreatment solution for copra oil processing plants, laying a solid foundation for subsequent oil pressing or solvent extraction operations.
🟢 Cleaning Section
Vibrating screens, destoners, and high-intensity magnetic separators are applied to efficiently remove sand, fibers, and metal contaminants.
Purpose: To protect key processing equipment from abrasion and safety risks while ensuring crude oil purity and stable continuous operation.

🟡 Crushing and Flaking
Copra is crushed into uniform particles using toothed roll crushers or hammer mills, then flaked into thin sheets of 0.3–0.5 mm by double-roll flaking machines.
Purpose: To increase material surface area and effectively rupture cell structures, creating ideal conditions for oil release in pressing or solvent extraction systems.

🔵 Cooking and Conditioning
A multi-layer cooker precisely controls temperature (80–95 °C), moisture content (5–7%), and residence time.
Effect: Protein denaturation and oil aggregation improve material plasticity and oil fluidity, ensuring efficient oil extraction while optimizing copra oil flavor stability.

💡 Every step in pretreatment influences final oil quality and overall production efficiency.
