Corn germ oil is not only rich in unsaturated fatty acids, but also contains various nutrients such as vitamins necessary for maintaining life. It is an edible oil with high nutritional value. In many developed countries abroad, corn germ oil has always been considered a high-quality product among edible oils and is favored by many families.
The corn germ oil processing is mainly based on the pre-pressing-extraction method. The corn germ is first pressed, and then the corn germ oil is extracted by the separation of organic solvents. This method is called pre-pressing-extraction. The pre-pressing process can extract about 80% of the oil. Although the oil yield is low, the oil quality is good and high. The pre-pressed cake is crushed and sent to the corn oil extraction machine to extract the residual oil in the cake.
The amount of corn germ oil obtained by this method is large and the oil yield is very high. In addition, the corn germ oil extraction production line has a high degree of automation, high efficiency in the application of materials, and greater benefits. It is the method chosen by many corn germ oil production plants in my country. The main steps are cleaning, steaming, cooking, extraction, evaporation, and refining. The wet meal obtained by extraction can also be used for processing animal feed and other products after desolventizing and drying.
Although the pre-pressing-extraction process can improve the oil yield and cake utilization rate, it uses a large number of equipment and has a large volume, which has certain requirements for the investment budget of the oil plant. It is suitable for oil plants with large daily processing capacity. For small and medium-sized edible oil processing plants, it is recommended to use the cooking oil pressing process. First, the oil extracted by the traditional pressing process is more easily recognized by consumers. Second, the pressing process uses a variety of equipment models and specifications, and the equipment configuration is flexible. The edible oil production line can be configured according to the actual situation and needs of the oil plant, saving capital investment in equipment.
In the corn germ oil pre-pressing-extraction production line, a complete set of oil pressing equipment, extraction equipment and refining equipment are needed. For the oil mill, the quality of the equipment is the basis of the oil mill's production, and it also determines the oil yield and the quality of the finished oil. Especially for large-scale oil equipment such as extraction equipment, quality is an important guarantee for its safety. Therefore, when purchasing equipment, it is necessary to choose experienced, strong technical strength, and good after-sales service manufacturers to cooperate, so as to lay a good foundation for the production and safety of the oil mill. To purchase cooking oil extraction machine, it is recommended to visit Huatai Oil Machinery Factory.
