Groundnut/Peanut Oil Extraction Process
Before entering the peanut oil extraction machine, the peanut kernels should be pretreated. Peanut pretreatment includes cleaning, husking, crushing, steaming and frying processes.
- Cleaning: The peanut being transported to groundnut oil processing plant usually contains certain impurities (silt, gravel, iron filings, etc.). If these impurities aren't removed or selected out carefully, the oil extraction machine would be damaged, lower oil output and even cause faults and accidents. Cleaning peanuts before peanut oi press machine is beneficial to reduce oil loss and improve oil yield of peanut oil press, improve the quality of oil, cake and by-products and increase the processing capacity of peanut oil press equipment;
- Shelling: Peanuts should be shelled and then pressed to increase production capacity and peanut oil yield. Its supporting equipment is: sheller, separation screen, separator and so on.
- Crushing: The yield of peanut can be increased obviously by crushing, rolling and pressing. Its supporting equipment is: crusher, rolling machine, etc.
- Steaming and Frying: Steam frying is an important step to improve the oil yield, the commonly used method is to wet the oil first, and then dry the wok, so that the oil to meet the technical requirements of water and temperature.
- Oil Extraction: The pretreated peanuts can be pressed by peanut oil processing machine. The commonly used peanut oil press is screw oil press machine that can be used to process more than 30 kinds of oil crops such as peanut, rapeseed, oil sunflower, cottonseed, soybean, flaxseed, and more.
- Oil Filtering: Filtering is to remove the organic impurities contained in crude grounanut oil. The supporting equipment is plate and frame oil filter machine.
- Oil Refining: This process is designed to produce high quality edible cooking oil and prelong the storage period.
