In the realm of sesame oil production, the choice of extraction equipment and the control of pressing temperature are crucial factors that significantly impact the quality of the final product. This article delves into the two main types of sesame oil pressing equipment: hydraulic oil presses and screw oil presses. It aims to provide a comprehensive understanding of their working principles, suitable applications, and the influence of pressing temperature on oil quality, offering practical guidance for sesame oil manufacturers and equipment procurement decision - makers.
Hydraulic oil presses operate on the principle of using hydraulic pressure to extract oil from sesame seeds. The seeds are placed in a chamber, and hydraulic force is applied to squeeze out the oil. This process is relatively gentle, similar to how a sponge is squeezed to release water. On the other hand, screw oil presses work by using a rotating screw to crush and press the seeds. The screw gradually pushes the seeds through a narrowing chamber, increasing the pressure and extracting the oil. It can be likened to how a meat grinder works, continuously processing the raw materials.
For home workshops, a small - scale hydraulic oil press may be the ideal choice. It is relatively easy to operate and maintain, and can meet the daily oil - making needs of a family. With a production capacity of around 10 - 20 liters per day, it is a cost - effective option for small - volume production. Small and medium - sized oil mills, which require a higher production capacity, usually range from 50 - 200 liters per day. They can choose between hydraulic and screw oil presses based on their specific requirements. Hydraulic presses are suitable for producing high - quality, premium oils, while screw presses are more efficient for large - scale production. Industrial - level users, with a daily production capacity of over 500 liters, often prefer screw oil presses due to their high - speed and continuous operation capabilities.
Pressing temperature plays a vital role in determining the quality of sesame oil. High - temperature pressing can lead to the destruction of some of the beneficial nutrients in sesame oil, such as antioxidants and vitamins. It may also cause the oil to have a darker color and a stronger, sometimes unpleasant, odor. In contrast, hydraulic oil presses can achieve low - temperature pressing, usually below 60°C. This low - temperature process helps to preserve the natural flavor, aroma, and nutritional value of the sesame oil. For example, the content of sesamol, an important antioxidant in sesame oil, can be up to 30% higher in oil produced by low - temperature hydraulic pressing compared to high - temperature screw pressing.
Proper operation skills are essential for maximizing the efficiency and lifespan of the oil presses. For hydraulic oil presses, it is important to ensure that the hydraulic system is properly maintained, with regular checks of the oil level and pressure. Screw oil presses require regular cleaning of the screw and the chamber to prevent blockages. In terms of troubleshooting, common problems such as low oil output or abnormal noise can often be resolved by adjusting the pressure, checking the feeding rate, or replacing worn - out parts.
In conclusion, choosing the right oil press and controlling the pressing temperature are key steps in producing high - quality sesame oil. By understanding the working principles, suitable applications, and the impact of temperature on oil quality, sesame oil manufacturers can optimize their production processes and achieve better business results.
