In the grain and oil processing industry, the quality of oil extraction has always been a key concern. Traditional chemical extraction methods, although efficient, have some drawbacks. For instance, chemical solvents may leave residues in the oil, which could potentially pose risks to human health. In addition, these methods may also lead to the loss of some nutrients in the oil.
Physical pressing is an alternative method that has gained increasing attention in recent years. The principle of high - efficiency physical pressing technology is based on mechanical force. Through a series of processes such as crushing, pressing, and filtering, oil is separated from raw materials. The intelligent temperature control system plays an important role in this process. It can precisely control the temperature during pressing, which is crucial for maintaining the quality of the oil.
For example, in the processing of corn germ oil, the intelligent temperature control system can ensure that the temperature does not exceed a certain range, thereby preserving the natural nutrients and flavors of the oil. According to research, compared with traditional pressing methods, this advanced technology can increase the oil yield by about 5 - 10% and improve the quality of the oil significantly.
| Index | Physical Pressing | Chemical Extraction |
|---|---|---|
| Nutrient Retention | High. Can retain most of the vitamins, antioxidants, etc. | Low. Some nutrients may be lost during the extraction process. |
| Safety | High. No chemical solvents are used, reducing the risk of residue. | Relatively low. There may be solvent residues. |
To ensure the continuous stability of pressing efficiency and oil quality, adjusting pressing parameters and maintaining equipment are essential. For example, adjusting the pressure, speed, and temperature according to different raw materials can optimize the pressing process. Regular equipment maintenance, such as cleaning, lubrication, and inspection of key components, can extend the service life of the equipment and reduce the failure rate.
Let's take a well - known export - oriented grain and oil enterprise as an example. After adopting high - efficiency physical pressing technology, the enterprise's corn germ oil products have been well - received in the international market. The sales volume has increased by about 20% within one year, and the market share has also expanded. This shows that the optimization of technology can bring significant economic benefits and positive market feedback.
In conclusion, physical pressing technology, especially with the support of intelligent temperature control systems, has a key position in the extraction of healthy oils. It can not only improve the nutritional value and flavor stability of oils but also enhance the market competitiveness of enterprises. For export - oriented grain and oil enterprises, choosing physical pressing technology is a wise decision to achieve quality upgrading and market expansion.
