• What is peanut oil processing technology?
  • This chapter covers the technology used for processing peanut oil. It starts by explaining the pretreatment technology and peanut pressing technology for high temperature and cold pressing peanut oil. It then discusses the peanut oil extraction technology, which includes leaching and separation technology.
  • 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 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.
  • How does a peanut halving machine process peanuts?
  • In the peanut processing line, the dried peanut kernels are rapidly fed into the kernel-halving machine to peel the red skin. The machine processes the peanuts, and then the resulting halves are transported to the color sorting machine by a conveyor to effectively remove the yellow-spotted, moldy, worm-eaten, or incompletely peeled peanuts.
  • 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 are peanuts used in China?
  • In China, more than 50% of consumed peanuts are used for oil production. This has become the main pattern of peanut consumption in China. Currently, there are two pressing methods: high-temperature pressing and cold pressing.
