Pressing Material Guide:

• Partial oil material pressing process guidance as follows:
• • Peanut (Recommended 325AC-390)
    • Peanut oil (rich aroma type) hot pressing process: Crush peanuts -> roast the peanut granules in a flat-bottom wok -> feed them into the hydraulic oil press barrel for pressing.
    • Peanut oil pressed using this process has rich aroma, golden transparency, good taste, pressed oil does not require hydration treatment, no foaming when cooking.
    • Basically no filtration treatment needed, settling and bottling directly. COFCO Group high-end peanut oil uses pressing process (crushing, roasting, pressing, filtering equipment provided by our factory).
    • 
  • Sesame (Recommended 325AC-390)
    • Sesame oil hot pressing process: Drum roaster roast sesame - Direct barrel pressing. Sesame oil pressed using this process has rich aroma, sweet aftertaste, pressed oil does not require hydration treatment, no foaming when cooking.
