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.
How to make peanut oil in China?
Currently, there are two pressing methods: high-temperature pressing and cold pressing. More than 90% of oil production in China adopts the traditional technique of high-temperature pressing, and the peanut oil produced with this method has a strong fragrant flavor and is therefore greatly favored by consumers.
What equipment is used for cold pressing of peanut oil?
Figure 3.8. Flow chart of equipment for cold pressing of peanut oil. 2. First, a sheller is used to shell the peanuts, and then the peanut kernels are transported to the low-temperature drying oven to be dried after being subjected to precleaning, gravity/magnetic separation de-stoner cleaning, and grading.
