• 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.
  • 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 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 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 production flow of cold pressing peanut oil?
  • The production flow of the cold pressing process of peanut oil is shown in Fig. 3.3. The temperature rises from 60 to 90¡ãC during the process, and the oil/residual oil ratio of the system decreases gradually, reaching 4.5% at 90¡ãC (as shown in Fig. 3.4).
  • Why do we dehull peanut oil before oil pressing?
  • The purpose of dehulling before oil pressing is to reduce the absorption of oil by the shell, increase the yield of oil, improve the processing efficiency of the peanut oil processing machine and reduce equipment wear and tear. This oil can also improve cake quality and added value.
