Comprehensive Solutions for Grain and Oil Machinery: The Composition of the Production Chain from Oil Pressing to Refining

Working Principle of the Single - Unit Oil Press

The single - unit oil press extracts natural edible oil from oilseeds such as peanuts, sunflower seeds, sesame, rapeseeds, and soybeans through physical pressing. It primarily consists of a motor, a transmission device, a pressing chamber, and an oil collector. The operation of the machine involves the following two key steps: extraction and filtration.

Extraction Phase

When the oilseeds are placed in the hopper of the single - unit oil press, the rotating screw pushes them forward. During this process, the oilseeds are gradually compressed, and the temperature rises. When the oilseeds enter the pressing chamber, physical and chemical changes occur under high - temperature and high - pressure conditions. The oil molecules in the oilseeds break, separating the oil from other solid substances. The rotation of the screw provides sufficient friction to stir and heat the oilseeds, facilitating the release of oil.

Filtration Phase

After the extraction phase, the resulting mixture passes through an oil - residue perforated plate into the filtration section. Through the double - filtration of cloth strips and filter screens, the oil is separated from suspended solids. The cloth strips mainly filter the oil, while the filter screens filter smaller suspended particles. Eventually, pure oil is obtained.

Advantages and Features of the Single - Unit Oil Press

• High Efficiency and Energy Saving: Compared with old - style equipment, the design is advanced and the performance is reliable. The normal oil yield can be 2 - 3 percentage points higher. For every 100 kilograms of peanuts processed, an average of 2 - 6 kilograms more oil can be produced, leading to significant annual economic benefits. Meanwhile, with the same production capacity, power consumption is reduced by 40%. Based on an average power consumption of 6 kWh per hour, daily production can save about 30 dollars in electricity costs.
• Easy Operation: It features one - key control, making the operation process simple and hassle - free.
• Convenient Maintenance: The design fully considers maintenance convenience, simplifying daily maintenance.
• High Oil Yield: With multi - stage pressing function, it can complete one - time pressing with a high oil yield.
• Energy Saving: With the same production capacity, it can reduce power consumption by 40%, achieving energy - saving effects.
• Labor - Saving: With the same production capacity, it can save 60% of labor. Only 1 - 2 people are needed to organize production, saving about 40 dollars per day in labor costs.
• Wide Application: It can press more than 30 types of oilseeds, including peanuts, sesame, flaxseeds, rapeseeds, sunflower seeds, cottonseeds, and soybeans.
• Pure Oil Quality: The residue is vacuum - filtered, ensuring the purity of the oil and meeting health and quarantine standards.
• Small Footprint: A single - unit oil press only requires 10 - 20 square meters of space for a pressing workshop.
