The oil extraction process of corn germ oil mainly includes cleaning, drying, softening, rolling, steaming and pressing. These steps are interrelated and jointly determine the quality and yield of the final oil. In the oil extraction process, the process parameters of each step, such as temperature, moisture content, pressure, etc., need to be strictly controlled to ensure the stability and continuity of the oil extraction process.
Corn germ oil extraction machinery usually consists of multiple parts such as pretreatment equipment, pressing equipment, leaching equipment and refining equipment.
1. Pretreatment equipment: used to clean, crush, soften, roll and other treatments of corn germ to improve its oil yield and oil quality. Cleaning equipment includes vibrating screens, magnetic separators, etc., which are used to remove impurities in germs; softening equipment adjusts moisture and temperature to make the germs have suitable plasticity; rolling equipment rolls the softened germs into thin sheets for easy pressing.
2. Pressing equipment: The pretreated corn germs are sent into the press to squeeze out the oil by mechanical pressure. Common pressing equipment includes screw oil press, hydraulic oil press, etc. These equipment can efficiently extract oil from germ while maintaining the quality of oil.
3. Extraction equipment: In order to increase the oil yield, the cake after pressing needs to be extracted. The extraction equipment uses solvents (such as solvent No. 6) to extract the remaining oil in the cake to form a mixed oil. Subsequently, the solvent is evaporated through the mixed oil evaporation and stripping system to obtain wet meal and crude oil.
4. Refining equipment: The crude oil is refined to remove impurities, free fatty acids, phospholipids, pigments, odors, etc., and finally obtain finished corn oil that meets the standards. Refining equipment includes deacidification tower, decolorization tower, deodorization tower, etc.
1. High efficiency: The use of advanced oil extraction technology and equipment can maximize the extraction of oil components in corn germ and improve the oil yield.
2. Strong pretreatment ability: The pretreatment equipment can efficiently remove impurities and moisture in the germ and improve the quality and purity of the oil.
3. Good stability: The pressing equipment and leaching equipment can provide stable pressure and temperature control to ensure the stability and continuity of the oil extraction process.
4. High degree of automation: Modern corn germ oil extraction machinery mostly adopts automated control systems, which can realize automated monitoring and adjustment of the entire oil extraction process, reducing manual intervention and operation
Corn germ oil extraction machinery is suitable for large, medium and small oil processing plants and food processing companies. These companies can use this type of machinery to efficiently and stably produce high-quality corn germ oil to meet market demand.
