• 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 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 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 are the optimal conditions for peanut oil extraction?
  • The optimal conditions for the extraction process were found to be a pressure of 8000 psi and a temperature of 80 ¡ãC. Lower temperatures resulted in decreased extraction rates. Furthermore, a 3-min holding time was the most effective for dissolving peanut oil up to the saturation level in the SC-CO 2 fluid.
  • What are the disadvantages of high-temperature pressing peanut oil?
  • The high-temperature pressing method for producing peanut oil results in poor sensory quality and heavy loss of vitamin E, sterol, wheat germ phenol, phospholipid, and other nutritional factors. Furthermore, the oil produced has poor stability.
  • 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.
