• 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)
  • 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 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.
  • 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.
  • 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.
  • Can mechanical shelling be used for peanuts?
  • Mechanical shelling can be used for peanuts in peanut oil production, as there is not a high requirement for undamaged peanut kernels. Mechanical shelling is both time-saving and labor-saving, but tends to cause mechanical damage to the peanuts. (3.1.3. Grading and Selection)
