This chapter covers peanut oil processing technology. It starts by explaining the pretreatment technology and peanut pressing technology of high temperature and cold pressing peanut oil. It then discusses the peanut oil extraction technology, which includes leaching and separation technology.
What is peanut oil extraction technology?
Peanut Oil Extraction Technology The leaching method, also named the extraction method, is a method that uses certain organic solvents that can dissolve fat to spray and immerse the oil-bearing materials so as to eventually separate the fat from the materials.
What are the different methods of peanut oil production?
Currently, there are two main methods of peanut oil production: a) Traditional Pressing (Mechanical Method): In this method, a peanut oil press is utilized to squeeze out the oil from the peanuts. The mechanical force applied through pressing allows the oil to be extracted effectively.
How is peanut oil extracted?
Mechanical pressing can extract 85% oil and the remaining oil is extracted by the solvent extraction method. According to mechanical pressing technology, you can divide the peanut oil production process into three phases. These are peanuts preparation, pressing and crude oil refining. Step 1: Cleaning Step 2: Dehulling Step 3: Cooking
