In the global market of soybean oil presses, screw oil presses and hydraulic oil presses are two mainstream types. Understanding their differences is crucial for foreign trade customers to make informed decisions.
Screw oil presses operate by using a rotating screw to gradually compress the soybeans, squeezing out the oil. This process is continuous and can handle large - scale production. On the other hand, hydraulic oil presses use hydraulic pressure to press the soybeans. The structure is relatively simple, mainly consisting of a hydraulic cylinder and a pressing chamber.
| Type | Working Principle | Structure |
|---|---|---|
| Screw Oil Press | Rotating screw compresses soybeans continuously | Complex, with multiple components for continuous operation |
| Hydraulic Oil Press | Hydraulic pressure presses soybeans | Relatively simple, mainly hydraulic cylinder and pressing chamber |
In terms of production efficiency, screw oil presses can process up to 5 - 10 tons of soybeans per day, suitable for large - scale industrial production. Hydraulic oil presses, however, have a lower production capacity, usually around 0.5 - 2 tons per day, which is more suitable for small - scale operations.
Regarding oil quality, hydraulic oil presses are superior in cold - pressing. Cold - pressing at low temperatures can retain up to 90% of the nutrients and original flavor of the oil. Screw oil presses, especially in hot - pressing mode, may cause some nutrient loss due to high - temperature processing.
In terms of operation difficulty, screw oil presses require more professional operators due to their complex structure and continuous operation requirements. Hydraulic oil presses are relatively easy to operate, and even novice operators can quickly master the operation skills.
For maintenance costs, screw oil presses have higher maintenance costs because of their many components and high - speed operation. Hydraulic oil presses have relatively lower maintenance costs as they have fewer components and simpler structures.
For small - scale cold - pressing operations, hydraulic oil presses are the ideal choice. They can meet the needs of small - scale high - quality processing, especially for producers who focus on the nutritional value and flavor of the oil.
In the production of high - end cold - pressed edible oils, hydraulic oil presses play a key role. The cold - pressing process can effectively maintain the natural antioxidants and unsaturated fatty acids in the oil, providing consumers with healthier and more delicious edible oils.
The integrated oil filtration technology in modern hydraulic oil presses can significantly improve the purity of the oil. It can remove up to 95% of impurities in the oil, reducing the need for additional filtration equipment and improving production efficiency.
This technology also promotes the upgrading of the oil - pressing industry, making the production of high - quality edible oils more efficient and environmentally friendly.
Based on real - world cases, if a customer has a small - scale production demand (less than 2 tons per day) and focuses on high - quality oil production, a hydraulic oil press with integrated oil filtration technology is highly recommended. For large - scale industrial production (more than 5 tons per day), a screw oil press may be a better choice.
