A peanut oil making machine is a valuable tool for cooking oil production. Proper usage not only improves oil yield but also extends the machine’s lifespan. Here are some practical tips to help you operate your peanut oil press more effectively.

1. Pre-Treatment of Peanuts

• Cleaning & Sorting: Remove impurities, stones, or moldy peanuts before pressing. Wash them thoroughly to avoid damaging the machine.
• Drying or Roasting: The moisture content should be around 5%-8%. Overly wet peanuts reduce oil yield, while overly dry ones may produce a burnt flavor. Light roasting (60-80°C) enhances oil extraction.

2. Machine Preheating & Adjustment

• Warm-Up the Press: Let the machine run empty for 3-5 minutes to heat the pressing chamber (optimal temperature: 60-80°C), improving oil flow.
• Adjust the Screw Press Gap: Depending on peanut size and dryness, fine-tune the screw pressure. Too tight may cause jamming; too loose reduces efficiency.

3. Optimizing the Pressing Process

• Even Feeding: Avoid overloading the hopper. A steady, controlled feed prevents clogging.
• Check the Oil Cake: A well-pressed cake should be thin and slightly oily. If too wet, tighten the screw; if too dry, check peanut moisture levels.

4. Maintenance & Cleaning

• Remove Residue After Use: Clean the pressing chamber and filter to prevent oil buildup, which can affect performance.
• Regular Lubrication: Apply food-grade oil or grease to bearings and gears to minimize wear.

5. Safety Precautions

• Avoid overloading the machine—take breaks to prevent motor overheating.
• Keep hands away from the discharge outlet to prevent burns or injuries.

By following these tips, you can maximize oil yield, ensure better-quality peanut oil, and keep your peanut oil making machine running smoothly for years.
