In the current international grain and oil processing market, physical pressing technology has gained significant preference among customers. According to a recent report from a leading industry research institution, over 70% of international customers express a higher inclination towards products made by physical pressing. This is mainly because physical pressing technology can effectively retain the nutritional components and natural flavor of vegetable oils.
For modern grain and oil processing enterprises, understanding and applying physical pressing technology is crucial for enhancing product quality and brand competitiveness. In the following sections, we will take the high - efficiency corn germ oil press as an example to explore the technical features and advantages of physical pressing technology.
The high - efficiency corn germ oil press is equipped with an intelligent temperature control system, which is one of its core technological advantages. The intelligent temperature control system can precisely regulate the temperature during the pressing process, ensuring that the nutritional components of the oil are not destroyed.
Specifically, during the pressing process, the temperature of the oil can be maintained at an optimum level, usually between 40 - 60 degrees Celsius. At this temperature range, the natural flavor of the oil is fully retained, and the degradation of nutrients such as vitamins and antioxidants is minimized. As shown in Figure 2, the intelligent temperature control system can automatically adjust the heating device according to the input and output parameters of the press.
The physical pressing process mainly relies on mechanical pressure to extract oil from oilseeds, without using any chemical solvents. This simple and natural extraction method can maximally preserve the nutritional components and natural flavor of the oil. Compared with chemical extraction methods, physical pressing can retain over 95% of the original nutrients in the oilseeds.
For example, in the case of corn germ oil, the physical pressing process can effectively retain vitamin E, linoleic acid, and other unsaturated fatty acids. These nutrients are not only beneficial to human health but also contribute to the unique flavor of the oil. A study conducted by a well - known food research laboratory shows that the physical - pressed corn germ oil has a more intense and pure natural flavor compared to other extraction methods.
In the process of grain and oil processing, enterprises often encounter problems such as flavor loss and low oil yield. For flavor loss, enterprises can adjust the pressing speed and temperature parameters. Generally speaking, reducing the pressing speed and maintaining a moderate temperature can effectively prevent flavor loss.
Regarding low oil yield, regular maintenance of the pressing equipment is essential. For example, cleaning the filter screen of the press every 20 - 30 working hours and lubricating the mechanical components can improve the oil yield. It is recommended to replace the worn - out parts in time to ensure the normal operation of the equipment.

In summary, physical pressing technology, especially when combined with high - end equipment such as the corn germ oil press, offers significant advantages in modern grain and oil processing. It can retain the nutritional components and natural flavor of oils, and help enterprises solve common processing problems.
