This chapter covers the technology used for processing peanut oil. It starts by explaining the pretreatment technology and peanut pressing technology for high temperature and cold pressing peanut oil. It then discusses the peanut oil extraction technology, which includes leaching and separation technology.
What equipment is used for cold pressing of peanut oil?
Figure 3.8 shows the equipment used for cold pressing of peanut oil. First, a sheller is used to shell the peanuts. Then, the peanut kernels are transported to the low-temperature drying oven for drying after being subjected to precleaning, gravity/magnetic separation, and de-stoner cleaning.
What technology is used for extracting peanut oil?
The leaching method, also known as the extraction method, is the technology used for extracting peanut oil. It involves using certain organic solvents that can dissolve fat to spray and immerse the oil-bearing materials, eventually separating the fat from the materials.
How is cold-pressed peanut oil produced?
After being filtered with a frame filter, the cold-pressed crude oil is processed to obtain the product oil, which is then packaged by a filling machine to form cold-pressed peanut oil products ( Fig. 3.8 ). Figure 3.8 illustrates the equipment used for cold pressing of peanut oil.
