• 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 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).
  • 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 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.
  • 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.
  • How is cold-pressed peanut oil produced?
  • After being filtered with a frame filter, the cold-pressed crude oil is processed to obtain the product oil, which is then packaged by a filling machine to form cold-pressed peanut oil products ( Fig. 3.8 ). Figure 3.8 illustrates the equipment used for cold pressing of peanut oil.
