This tutorial systematically explains how to improve the pressing efficiency of corn germ oil. It covers the full - process physical pressing technology, from raw material pre - treatment, adjustment of the intelligent temperature control system, to optimization of pressing parameters and oil separation. By analyzing common problems and solutions in actual production, it helps users master efficient equipment operation skills to ensure both oil quality and production capacity are improved.
Before starting the corn germ oil pressing process, proper equipment preparation is crucial. It is recommended to conduct a comprehensive inspection of all pressing equipment. For example, check the wear of the screw press's screw shaft. It is estimated that a worn screw shaft can reduce pressing efficiency by up to 20%. Ensure that all parts are in good working condition, and lubricate the necessary parts. Regular maintenance can extend the service life of the equipment by about 30%.
Raw material pre - treatment plays a vital role in improving the pressing efficiency of corn germ oil. First, remove impurities from the corn germ. Impurities can not only damage the pressing equipment but also reduce the quality of the oil. According to industry statistics, by removing impurities, the oil yield can be increased by 3 - 5%. Then, adjust the moisture content of the corn germ. The optimal moisture content is generally around 10 - 12%. If the moisture content is too high or too low, it will affect the pressing effect.
The intelligent temperature control system is an important part of the physical pressing process. During the pressing process, the temperature should be strictly controlled. Generally, the pre - heating temperature of the corn germ is recommended to be around 80 - 90°C, and the pressing temperature is maintained at about 110 - 120°C. Proper temperature control can improve the fluidity of the oil, thereby increasing the oil yield. An improper temperature can lead to a decrease in oil yield by approximately 10%.
Optimizing the pressing pressure is also key to improving efficiency. The pressing pressure should be adjusted according to the state of the raw materials and the performance of the equipment. Generally, for small - scale presses, the pressure can be controlled between 15 - 20 MPa, while for large - scale industrial presses, the pressure can reach 30 - 40 MPa. Reasonable pressure adjustment can ensure maximum oil extraction without damaging the oil quality.
After pressing, efficient oil separation is necessary to obtain high - quality corn germ oil. Centrifugal separation is a common method. It can quickly and effectively separate the oil from the residue. The separation efficiency can reach up to 95% under normal circumstances. Ensure that the separation equipment operates stably to avoid oil loss during the separation process.
For small - scale production lines with a daily output of less than 10 tons, simple and cost - effective equipment can be selected. For medium - scale production lines with a daily output between 10 - 50 tons, more automated and efficient equipment is required. And for large - scale production lines with a daily output of more than 50 tons, high - end, fully automated equipment should be used to ensure production efficiency and product quality.
In conclusion, by mastering the full - process physical pressing technology of corn germ oil, including equipment preparation, raw material pre - treatment, temperature control, pressing pressure adjustment, and oil separation, and choosing the appropriate equipment according to different production scales, users can effectively improve the pressing efficiency of corn germ oil.
