When it comes to sesame oil extraction, hydraulic and screw oil presses are two main types of equipment widely used in the market. Understanding their working principles is crucial for making informed decisions.
The hydraulic oil press operates on the principle of using hydraulic pressure to compress the sesame seeds. This process is carried out at a relatively low temperature, typically around 40 - 60 degrees Celsius. The low - temperature extraction helps to preserve the natural flavor and nutrients of the sesame oil, resulting in a high - quality product. For example, the vitamin E and unsaturated fatty acids in the oil are better retained, which are beneficial for human health.
On the other hand, the screw oil press works by continuously pushing the sesame seeds through a screw mechanism. During this process, friction generates heat, and the temperature can reach 100 - 120 degrees Celsius. This high - temperature operation allows for continuous and high - volume production, making it suitable for large - scale industrial applications.
For family workshops, where the production scale is usually small, around 10 - 50 kilograms of sesame seeds per day, the hydraulic oil press is an ideal choice. Its low - temperature extraction ensures high - quality oil, which can be sold at a premium in the local market. The batch - processing nature of the hydraulic press also allows for more flexibility in production, as the family can adjust the production volume according to the demand.
Small and medium - sized oil mills, with a daily production of 50 - 500 kilograms of sesame seeds, need to balance between oil quality and production efficiency. If the mill focuses on high - end market segments that value oil quality, the hydraulic oil press can be used for a portion of the production. However, if there is a large demand for bulk oil, a combination of both hydraulic and screw oil presses can be considered. For instance, the screw press can handle the large - volume production during peak seasons, while the hydraulic press can be used for producing special - grade oil.
In industrial production, where the daily production volume can exceed 500 kilograms of sesame seeds, the screw oil press is more commonly used due to its high - volume and continuous production capabilities. However, some industrial producers may also use hydraulic oil presses to produce high - end, niche products to meet different market demands.
When choosing between a hydraulic and a screw oil press, several key factors should be taken into account:
Proper operation and maintenance of the oil press are essential for ensuring its performance and longevity.
For hydraulic oil presses, regular inspection of the hydraulic system, including checking the oil level and the condition of the seals, is necessary. The press should be cleaned after each use to prevent the accumulation of sesame residues, which can affect the oil quality. When operating, it is important to follow the recommended pressure and temperature settings to avoid damage to the equipment.
For screw oil presses, the screw mechanism needs to be lubricated regularly. The feeding speed should be adjusted according to the capacity of the press to ensure continuous and efficient operation. In case of blockages, proper cleaning procedures should be followed to avoid damage to the screw.
In conclusion, the hydraulic oil press offers unique advantages in small - to - medium - scale sesame oil production, especially in terms of oil quality. By carefully considering the production scale, oil quality requirements, and budget, exporters and sesame oil processing enterprises can make the right equipment purchase decision.
