Research on Oil quality influencing factors of screw expeller press machine

Screw expeller press is an important oil pressing equipment, and its oil quality directly affects the quality and market competitiveness of the final product. This article aims to deeply explore the Oil quality influencing factors of screw expeller press machine and conduct a systematic analysis of these factors in order to provide theoretical basis and practical guidance for improving oil quality. 

Oil quality influencing factors of screw expeller press machine

Screw expeller press Oil quality is affected by many factors. These factors are complex and interact with each other to determine the final quality of the oil. Among them, the key influencing factors include: 

1. Raw material quality

The quality of raw materials is the primary factor that determines the quality of oil products. Different types of oils have differences in their chemical composition, physical properties and water content, which directly affects the quality of the oil. For example, raw materials with too high water content can easily lead to a decline in oil quality, odor and instability. In addition, the maturity, freshness and impurity content of raw materials also have a significant impact on oil quality. 

2. Screw expeller press structure and parameters

The structural design and parameter setting of the Screw expeller press are also crucial to the oil quality. Parameters such as the spiral blade design of the oil press, the size of the pressing chamber, oil pressing pressure, and oil pressing speed will all affect the extraction efficiency of oil and impurities during the oil pressing process, thereby affecting the quality of the oil. For example, unreasonable design of the spiral blades will cause the oil to generate excessive heat during the pressing process, thereby destroying the quality of the oil. If the pressing pressure is too high, it may cause oxidation and deterioration of the oil. The working parameters of the Screw expeller press need to be adjusted according to the characteristics of different oils to achieve the best oil extraction effect and oil quality. 

3. Oil extraction process

The impact of oil extraction technology on oil quality cannot be ignored. A reasonable oil extraction process can effectively control key parameters such as temperature, pressure, and time during the oil extraction process, thereby maximizing the retention of the nutrients and flavor characteristics of the oil. For example, controlling the oil pressing temperature can effectively prevent the oxidation and deterioration of oil, while a reasonable oil pressing time can ensure the full extraction of oil. In addition, impurity removal and oil filtration during the oil extraction process are also key links to ensure oil quality. 

4. Post-processing process

The post-treatment process is an important link in ensuring oil quality. For example, for some oil products that require further refining, a reasonable refining process can effectively remove impurities and odors in the oil, thereby improving the quality and stability of the oil. 

To sum up, Oil quality influencing factors of screw expeller press machine are complex and diverse, including factors of the raw material itself, as well as factors of oil extraction equipment and technology. Only by systematically considering these factors and taking targeted measures can the quality of Screw expeller press oil products be effectively improved. Future research should further explore the optimal pressing parameters of different oils under different Screw expeller press conditions, and develop more environmentally friendly and energy-saving oil pressing processes to meet the growing market demand.
