Peanut butter is a widely beloved condiment enjoyed globally, available in both sweet and salty varieties. It is especially prevalent in Western cuisine, while also being widely used in Chinese cuisine for hot pot dipping sauces, mixed noodles, lo mein, and stir-fried dishes. The HESHAN® peanut butter production line can produce both smooth and chunky peanut butter (by adding peanut or other nut pieces to the smooth peanut butter, providing a chewier texture). Examples include mixed peanut and nut butter, chunky peanut butter, salted peanut butter, and smooth peanut butter.
Process Description
Process Description
HESHAN® peanut butter production line is an integrated, continuous industrial system designed to process raw peanuts into smooth, crunchy, or flavored peanut butter. The complete set of HESHAN® Peanut Butter Production Line consists of the lifting conveyor, the peanut roaster (with cooling function), the peanut peeler, the screening machine, the coarse grinder, the fine grinder, the cooler, the deaeration mixer, the automatic filling machine, and auxiliaries:
Peanut lifting and conveying → Peanut cleaning → Peanut roasting → Cooling → Peanut peeling → Screening → Pre-grinding → Fine grinding → Blending → Secondary cooling → Deaeration → Automatic filling → Automatic capping machine → Continuous induction sealing machine → Peanut butter jar labeling machine.
Production Line Process Flow
Production Line Process Flow
The industrial manufacturing process flows through several sequential steps:
Roasting and Cooling
Roasting and Cooling
Roasting Machine: Heats raw peanuts at 160°C to 180°C (using either batch roasters or continuous belt hot-air roasters) to develop the signature aroma, color, and flavor.
Cooling Conveyor: Uses powerful suction fans to rapidly cool the roasted peanuts in order to preserve natural oils and prevent overcooking.
Peeling and Sorting
Peeling and Sorting
Peeling/Blanching Machine: Gently rubs the peanuts together to break loose the outer skins, which are often used for animal feed.
Picking/Sorting Belt: Allows workers or optical sensors to remove bad kernels, bitter hearts, and foreign debris to maintain high food quality.

Grinding and Homogenization
Grinding and Homogenization
Coarse Grinder: Crushes the peanuts into an initial coarse paste.
Ultrafine/Colloid Mill: Processes the paste to a microscopic level to achieve a velvety texture for smooth peanut butter, or leaves it coarser for chunky varieties.
Mixing and Degassing
Mixing and Degassing
Mixing/Blending Tank: Integrates minor ingredients such as salt, sugar, honey, or hydrogenated vegetable oil (which acts as a stabilizer to prevent oil separation).
Vacuum Degassing Tank: Removes trapped air bubbles from the paste to extend shelf life and enhance color stability.
Packaging and Sterilization
Packaging and Sterilization
Filling and Sealing Machines: Dispenses the prepared paste into retail or commercial jars, hermetically seals them with foil or induction heat, and labels the finished goods. .
