Huatai Intelligent Equipment Group provides one-stop customized solutions for peanut oil production lines, covering the entire process from raw material handling to finished oil packaging. With advanced technology and stable equipment, we deliver high-quality, high-efficiency production while meeting environmental and safety standards.
1. Peanut Pretreatment – Quality Starts with Raw Materials
- Shelling & Separation: Peanuts are uniformly fed into a sheller, where shells are removed through impact, friction, and rubbing. Grading screens and air separation then achieve clean kernel-hull separation.
- Crushing & Cooking: Crushing increases surface area for heat and moisture transfer. For hot pressing, precise cooking at 120–130℃ with 1–2% moisture breaks cell walls and denatures proteins, laying the foundation for high oil yield and rich flavor.
2. Peanut Oil Pressing – Hot vs. Cold
- Hot Pressing (Traditional): High-temperature cooking (~120℃) delivers high oil yield, strong aroma, and good storage stability – ideal for mainstream consumer oils.
- Cold Pressing (Nutritional): Operating at ≤60℃ without high-temperature cooking preserves vitamin E, sterols, and other nutrients. The remaining protein can be fully utilized – suitable for premium health oils.
- Pressed peanut cake can be used as high-quality animal feed or further extracted to maximize resource utilization.
3. Peanut Oil Refining – From Crude to Grade 1 Oil
- Pressing or extraction alone cannot produce stable, safe, high-quality edible oil. Refining removes impurities to enhance purity, flavor, and shelf life.
- Degumming: Removes phospholipids and colloidal impurities to prevent oil cloudiness and rancidity
- Deacidification: Reduces free fatty acids using alkali refining or distillation to improve stability
- Decolorization: Adsorbents remove pigments, resulting in clear, bright oil
- Deodorization: High-temperature vacuum distillation removes odors and volatile substances – physical refining at ~260°C ensures pure flavor and clean taste
