The production efficiency is higher, and the processing flow is safer and more hygienic. Next, let's take a look at the peanut butter manufacturing process in a factory.

1. Removing stones and impurities
Separation of side-by-side stones, sand, leaves, and other impurities to ensure the normal operation of subsequent processing equipment without damaging the machine.
2. Color selection
Through the color sorter, the peanuts such as mildew and insects are removed in time, and the peanuts exceeding the standard of aflatoxin are quickly and accurately screened, so that the finished peanut butter meets the standard. Selected peanuts with full grain and normal smell.
3. Roasting
The peanuts are roasted by drum roasting equipment or continuous roasting equipment, the roasting temperature is 180℃-200℃, and the roasting time is 30-40 minutes. The ideal state of roasting: the peanut kernels are uniform in color, fully cooked and free of scorching.

4. Cooling, peeling

The roasted peanuts are cooled by a fan. After cooling, the outer skin of peanuts can be removed by rubbing lightly. Use a professional half-peeling machine to remove the red coat of the peanuts, and the peanut kernels are crushed into granules, which is more convenient for the subsequent grinding process.
5. Coarse grinding, fine grinding
Coarse grinding is carried out first, and the added accessories are melted by heating up in the coarse grinding, and then the peanut butter grinder is used for fine grinding, and finally the peanut butter is fine and smooth.
6. Cooling down
The special sauce cooler can quickly cool down the peanut butter and prevent the color composition of the sauce from changing due to long-term high temperature, which will affect the appearance and taste.
7. Degassing
Vacuum degassing tanks are usually used to vacuum degas the sauce body, thereby inhibiting browning, oxidation of pigments, vitamins, aroma components and other substances, preventing the quality of peanut butter from being degraded. In addition, degassing also reduces foaming during autoclaving and filling, improving sterilization.
8. Filling
Sterilize the bottle for 20 minutes before filling. Using a special sauce filling machine, the measurement is accurate, the filling volume is adjustable, and the filling temperature is between 10 °C - 20 °C.
