• What technology is used in peanut oil production?
  • 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 to make peanut oil from groundnuts?
  • Shelling: Groundnuts with shells should use Groundnut sheller to remove the shells to increase the oil yield, improve the quality of the oil and cake and smooth the following peanut oil production process. The equipment used for this process will be the Groundnut shelling machine. Grading:
  • 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.
  • 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¡ãC during the process, and the oil/residual oil ratio of the system decreases gradually, reaching 4.5% at 90¡ãC (as shown in Fig. 3.4).
  • How is superfine fragrant peanut oil produced?
  • The crude oil undergoes sedimentation, and then is pumped into the frame filter for filtration to produce superfine fragrant peanut oil ( Fig. 3.9 ). Figure 3.9 illustrates the equipment flow chart for superfine fragrant peanut oil production.
