Peanut butter is a popular food, what is the process of peanut butter making outline? Following is the main process:
 

1. Raw material screening
First, purchase high-quality peanuts and conduct strict screening. Through mechanical screening and manual selection, remove bad peanuts, moldy peanuts, foreign objects, etc. to ensure the quality of the final product.
 
2. Shelling
Peanuts will go through a shelling machine to remove the shells and further screen out broken or unqualified peanuts.
 
3. Roasting
The peanuts will enter the roaster for heating. This process can remove excess moisture, enhance the aroma of peanuts, and promote saccharification reaction, making the taste of peanut butter more mellow.
 
4. Cooling and removing the peanut skin
The roasted peanuts need to be cooled quickly to prevent over-roasting and affecting the taste. After cooling, the red peanut skin needs to be removed to improve the fineness of the peanut butter.
 
5. Grinding
The peeled peanuts are put into the grinder for grinding, turning the peanuts into a uniform paste. During this process, salt, sugar or vegetable oil can be added as needed to improve the taste and extend the shelf life.
 
6. Homogenization and blending
The ground peanut butter needs to be mixed by a homogenizer to evenly distribute the oil and solid particles and prevent oil and water separation. At the same time, different ingredients can be added according to market demand to produce peanut butter with different flavors.
 
7. Sterilization
In order to ensure the safety of peanut butter, pasteurization or high-temperature instant sterilization is required to eliminate possible harmful microorganisms and extend the shelf life of the product.
 
In addition to the above production process, it is usually necessary to add a packaging step to realize an automated peanut butter production plant.
