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 is peanut oil processing technology?
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 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.
What is the production flow of cold pressing peanut oil?
The production flow of the cold pressing process of peanut oil is shown in Fig. 3.3. The temperature rises from 60 to 90°C during the process, and the oil/residual oil ratio of the system decreases gradually, reaching 4.5% at 90°C (as shown in Fig. 3.4).
