Corn germ oil is not only rich in unsaturated fatty acids, all kinds of life-sustaining essential vitamins and other nutrients, is a kind of edible oil with high nutritional value. In many foreign developed countries, corn germ oil has always been regarded as a high-quality product in edible oils, favored by many families' consumption.Good texture of corn germ oil color is golden and transparent, has a light fragrance, contains more than 80% of the unsaturated calculations, roughly divided into oleic acid and linoleic acid two kinds, in which there is as high as 56% of linoleic acid content.

Extraction of corn germ oil using the pre-pressing and extraction method.

Corn germ has the processing industry to pre-press extraction method, the first corn germ for pressing, and then use some organic solvents to separate the role of the oil will be extracted out of corn germ oil, this method is called pre-press extraction method. The pre-pressing process can extract about 80% of the oil, and the oil yield is low, but the oil quality is good and high. The cake after pre-pressing is crushed and sent to the extraction equipment to extract the residual oil in the cake.

High oil yield and automation of the pre-pressing and extraction method.

The amount of corn germ oil obtained by this method is larger and the oil yield is high. And the extraction production line has a high degree of automation, the application of the material is very efficient, so that the revenue is greater, so that many of our current corn germ oil production factories choose the method. Its main steps are cleaning, pressing, steaming and frying, leaching, evaporation, extraction and refining. The wet meal obtained from leaching can also be used in the processing of animal feed and other products after desolvation and drying.

Equipment requirements and applicability of the pre-pressing and extraction method.

Although the pre-press extraction process can improve the oil yield and cake meal utilization rate, but the number of equipment used, large volume, the investment budget of the oil plant has certain requirements, suitable for daily processing capacity of the oil plant, for small and medium-sized edible oil processing plant, it is recommended to use the pressing process, for one thing, the traditional pressing process extracted fats and oils are more likely to be recognized by consumers, and secondly, the pressing process used in the number of models of equipment specifications, equipment, configuration flexibility, according to the actual oil plant. The configuration is flexible, and the production line can be configured according to the actual situation and demand of the oil plant to save the capital investment on equipment.

Importance of equipment quality for oil plant production.

Pre-pressing extraction production line, you need to use a complete set of oil processing equipment, extraction equipment and refining equipment, for the oil plant, the quality of the equipment is the basis of the production of the oil plant, but also determines the rate of oil production and the quality of the finished product, especially for  extraction equipment such as this large-scale oil equipment, the quality of the decision to be an important guarantee of its safety, so in the purchase of equipment, choose the rich experience, process technology and technical strength of the strong, Therefore, when purchasing equipment, we should choose the manufacturer with rich experience, strong technical strength and good after-sales service, so as to lay a good foundation for the production and safety of the oil plant.
