Description

Technical Field

[0001] The present invention relates to the technical field of sesame oil pressing, and specifically to an innovative process for efficient and energy-saving sesame oil pressing. Background Art

[0002] There are many drawbacks in the traditional sesame oil pressing process. On the one hand, in the raw material processing link, simple screening and cleaning are difficult to completely remove impurities, which affects the quality of sesame oil; although the oil yield is relatively high in high-temperature baking, it is easy to cause the loss of sesame nutritional components and the damage of flavor. On the other hand, the pressing equipment is obsolete, with low pressing efficiency and high energy consumption. For example, in the pressing process of traditional screw presses, a lot of energy is consumed in mechanical friction, and it is difficult to accurately control the pressing parameters, resulting in unstable oil yield. In addition, the means of crude oil purification are limited. Only simple precipitation and rough filtration cannot effectively remove tiny impurities and moisture, resulting in a shortened shelf life and a decline in the quality of sesame oil. Under the increasing requirements of consumers for the quality of sesame oil and the general trend of energy conservation and emission reduction, there is an urgent need for a new, efficient and energy-saving sesame oil pressing process to overcome these problems.
