• 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.
  • How is peanut oil extracted?
  • Mechanical pressing can extract 85% oil and the remaining oil is extracted by the solvent extraction method. According to mechanical pressing technology, you can divide the peanut oil production process into three phases. These are peanuts preparation, pressing and crude oil refining. Step 1: Cleaning Step 2: Dehulling Step 3: Cooking
  • What percentage of peanuts are used for oil production?
  • A significant fraction of the peanuts grown around the world are used for oil production because peanuts contain relatively high amounts of oil (45%¨C55%). Peanut oil is typically isolated from peanuts using conventional extraction methods, such as mechanical pressing and solvent (n -hexane) extraction .
  • 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.
  • 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.
