In - depth Analysis of the Whole Process of Sesame Oil Pressing

In the global market of edible oils, sesame oil holds a special place due to its unique flavor and nutritional value. The application of screw pressing technology in sesame oil production has become a key factor for export - oriented enterprises to increase efficiency and reduce costs. This article will comprehensively analyze the entire process of sesame oil pressing.

Raw Material Selection Criteria

The first step in high - quality sesame oil production is raw material selection. High - quality sesame seeds should have an impurity content of ≤0.5%. Sesame with a high impurity content can not only affect the pressing efficiency but also reduce the quality of the final product. For instance, impurities may cause blockages in the pressing equipment and reduce the clarity of the oil.

The Impact of the Cleaning Process on Subsequent Pressing Efficiency

After raw material selection, the cleaning process is crucial. Mechanical impurity removal combined with air - selection techniques can effectively improve the purity of sesame seeds. Mechanical impurity removal can remove large - sized impurities, while air - selection can separate light impurities such as dust and chaff. According to industry data, a well - executed cleaning process can increase the subsequent pressing efficiency by 10% - 15%.

Cold Pressing vs. Hot Pressing: Differences in Flavor Retention and Nutritional Components

There are two main methods in sesame oil pressing: cold pressing and hot pressing. Cold pressing can retain more nutrients. For example, cold - pressed sesame oil can retain up to 80% of vitamin E, which is beneficial for human health. On the other hand, hot - pressed sesame oil has a stronger flavor, which is more popular in some regions. Operators need to choose the appropriate pressing method according to market demand.

Core Parameter Adjustment of Screw Pressing Equipment

Adjusting the core parameters of screw pressing equipment is the key to improving the oil - extraction rate. The pitch, rotation speed, and feeding speed need to be matched according to different sesame batches. For new operators, it may take some time to master these adjustment skills. However, with experience, they can significantly increase the oil - extraction rate by 15% - 25%.

Common Fault Troubleshooting and Optimization Suggestions

During the pressing process, some common faults may occur, such as blockages, uneven oil output, and turbid oil quality. For blockages, operators can adjust the feeding speed and check for foreign objects in the equipment. To solve the problem of uneven oil output, they need to adjust the pressure and temperature of the pressing process. As for turbid oil quality, improving the cleaning process and adding appropriate filtering steps can be effective solutions.

Scenario - Based Case Implantation

Let's take an export - oriented small factory as an example. By adjusting the pressing temperature and pressure, this factory achieved a 30% increase in daily production capacity. This case shows that proper parameter adjustment can bring significant benefits to enterprises.

In conclusion, if you want to improve the efficiency of sesame oil production and enhance the competitiveness of your products, mastering the screw pressing technology is essential.
