How to make high-quality peanut butter on a commercial scale? In this article, we’ll take you inside the industrial peanut butter making process, explaining the role of each stage and the equipment used.
Peanut Butter Production Process
The peanut butter making process follows these steps:
Feeding → Roasting → Cooling → Peeling & Half-Splitting → Cooling → Coarse Grinding → Fine Grinding → Seasoning & Mixing → Cooling → Vacuum Degassing → Storage for Filling or Packaging
How to Make Peanut Butter Step by Step
1. Raw Peanut Feeding
The process starts with feeding peanuts into the roaster. Depending on production scale, you can choose feed manually or automatically using lifters and conveyors. Automatic feeding not only reduces labor but also ensures continuous, efficient production.
Equipment Used: Pneumatic Lifter or Conveyor Belt
2. Roasting
Roasting is the most important stage for increasing the peanut butter’s flavor. Using batch drum roasters or continuous belt roasters, the peanuts are roasted to enhance their nutty taste, golden color, and roasted aroma.
Equipment Used: Peanut Roaster
3. Cooling
Once roasted, peanuts must be cooled quickly to stop the cooking process and prevent over-browning. Cooling machine can quickly lower down the temperature, locking in flavor while maintaining quality.
Equipment Used: Cooling Machine
4. Peeling & Splitting
Remove the thin red skins of peanuts and split the peanuts into halves. This step ensures a smooth texture and clean flavor — peanut skins can make butter taste slightly bitter and affect its appearance. The result is clean, light-colored peanuts, ready for grinding.
Equipment Used: Peanut Peeling and Half-splitting Machine
5. Grinding — From Peanuts to Paste
Grinding is the core of the peanut butter production process. It has two stages:
- Coarse Grinding: Peanuts are crushed into a rough paste.
- Fine Grinding: The paste is refined into a smooth, creamy consistency.
Equipment Used: Colloid Grinder
6. Mixing, Seasoning, Cooling & Vacuum Degassing
At this stage, optional ingredients such as sugar, salt, stabilizers, or flavorings are added. The peanut butter is then cooled and processed under vacuum to remove air bubbles — a crucial step for achieving a silky texture and longer shelf life.
Equipment Used: Mixing or Storage Tanks, Vacuum Tank
7. Storage & Packaging
Finally, the finished peanut butter is transferred to storage tanks before filling and packaging.
