What’s The Core Steps in Cottonseed Oil Processing?

In edible oil processing plant industry, cottonseed oil quality hinges on advanced technology.
Leveraging over 40 years of expertise, QIE GROUP's smart cottonseed oil production line integrates cleaning, dehulling, press / solvent extraction and refining to maximize oil yield:

1. Intelligent Pretreatment
Two-stage cleaning (vibrating screen + aspiration + magnet) → ≤0.5% impurities;
Disc huller (98% efficiency) → efficient kernel-shell separation.

2. Low-Temp Oil Extraction
Pre-pressing: Cotton seed oil extraction machine (screw oil press) retains natural flavor;
Extraction: Low-temp solvent process → ≤1% residual oil in meal.

✅ Critical control: Cooking temp ≤120°C (prevents gossypol denaturation)

3. Precision Refining
Alkali refining in edible oil refinery adapts flexibly to crude oil acid value;
Gossypol adsorption → 100% compliant with GB1537-2003

4. Full Resource Utilization
Linters → Textile materials; Meal → High-protein feed; Hulls → Mushroom substrate
