How Is Peanut Butter Made? Full Production Process & Equipment by SUOTE

      Do you know how high-quality peanut butter is produced? As a professional manufacturer with more than 20 years of experience, SUOTE provides a complete industrial peanut butter production line with precision equipment, stable performance, and long service life.

1. Raw Material Acceptance & Pretreatment

       High-quality peanut butter starts with carefully selected peanut kernels. We use stone removers, bubble washers, and magnetic separators to remove stones, impurities, and metal foreign matters, ensuring safe and clean raw materials.

Peanuts are roasted at a stable temperature of 180–185°C for 20–25 minutes. Proper roasting releases rich peanut aroma, reduces moisture, and improves oil output, which is essential for good flavor and texture.

3. Rapid Cooling

      After roasting, peanuts are quickly cooled to below 40°C to prevent overheating, burnt taste, and red skin adhesion.

4. Peanut Peeling & Sorting

      Peanuts are peeled and split by professional peeling machines, then sorted by color sorters to remove bad grains, burnt grains, and impurities.

5. Grinding (Core Process)

      Peanuts go through coarse grinding and ultra-fine grinding by high-precision colloid mills. The fineness can reach ≤30μm for smooth peanut butter. The grinding temperature is strictly controlled below 60°C to avoid oxidation.

6. Mixing & Sterilization

      Salt, sugar, emulsifiers, and stabilizers are added evenly in mixing tanks. The peanut butter is pasteurized at 100–110°C to ensure food safety and longer shelf life.

7. Vacuum Deaeration

      Vacuum deaeration removes air bubbles to prevent oxidation, stratification, and discoloration, keeping the peanut butter stable and fresh.

8. Cooling, Filling & Packaging

      The peanut butter is cooled to 35–40°C before filling. Automatic piston filling, capping, labeling, and packaging complete the entire production process.
