• Why do we use a cleaning machine for peanut extraction?
  • Batches of harvested peanuts will contain whole peanuts in the shell, some shelled peanuts, and foreign objects (e.g., leaves, nodes, weed seed, etc.). The peanuts are then cleaned using cleaning machine so that oil is not contaminated with foreign materials. Therefore, it helps to preform the extraction process as efficiently as possible.
  • 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 methods are used to extract peanut oil?
  • This review elucidates the methods used for extracting peanut oil, including mechanical and chemical processes that have been combined with biological or physical pre-treatment techniques. Their primary goals are to maximize oil extraction and unlock the untapped potential of defatted whole peanuts.
  • 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 solvent is used to extract peanut oil?
  • Two different solvents, n-hexane, and petroleum ether, were used. The moisture level of the peanuts used in the experiment was 6.68% d.b. The extraction process was carried out for 8 h at 100 ¡ãC with a solvent feeding rate of 4¨C5 drops per second. After the extraction, the peanut oil was distilled and held in an oven at 105 ¡ãC for 1 h.
