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)
How is cold pressed peanut oil extracted?
Commercial cold pressed extraction of peanut oil is carried out using a twin-screw press at temperatures below 60°C ( Wang, Liu, Hu, et al., 2016; Zheng, Ren, Su, Yang, & Zhao, 2013 ). Lastly, a frame filter is used to press and filter three times under 30°C to obtain the cold pressed peanut oil ( Wang, Liu, Hu, et al., 2016 ).
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).
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.
