The production of peanut oil involves several technologies. It starts with pretreatment technology and peanut pressing technology for high temperature and cold pressing. The oil is then extracted using leaching and separation technology. At the end of the process, the peanut oil production line and the relevant key equipment are discussed. (Section 3.1)
What is the process of peanut pretreatment called?
Peanut pretreatment is the term for the series of treatment processes before oil production. These processes include cleaning, shelling, grading and selection, drying, cooling, thermal conditioning, pressing, and cooking.
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.
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.
