Soybean oil is one of the most widely used vegetable oils in the world. Understanding the full - process of soybean oil pressing and optimizing the relevant equipment parameters can significantly improve the oil yield, which is crucial for small and medium - sized oil enterprises. This article will comprehensively analyze the soybean oil pressing process and explore how to enhance the oil yield through equipment parameter optimization.
The soybean oil pressing process starts from pre - treatment to final filtration. Pre - treatment includes cleaning, crushing, and conditioning of soybeans. These steps are essential as they can break the cell structure of soybeans, making it easier for oil to be released during the pressing process. After pre - treatment, the soybeans enter the pressing stage. The pressed oil then goes through a series of filtration steps to remove impurities, finally obtaining high - quality soybean oil.
The key equipment parameters such as pressure, temperature, and time have a significant impact on the oil yield. Scientific matching of these parameters is the key to improving the oil yield. For example, increasing the pressure within a certain range can squeeze more oil out of soybeans. However, excessive pressure may cause the oil to contain more impurities. The temperature also plays a vital role. An appropriate temperature can reduce the viscosity of the oil, making it easier to flow out. But too high a temperature may damage the nutritional components of the oil. Time is another important factor. A proper pressing time can ensure that the oil is fully squeezed out without causing excessive oxidation of the oil.
| Parameter | Effect on Oil Yield | Optimal Range |
|---|---|---|
| Pressure | Positive correlation within a certain range | 3 - 5 MPa |
| Temperature | Reduces oil viscosity and promotes outflow | 80 - 100°C |
| Time | Ensures full oil extraction | 30 - 60 minutes |
Mechanical pressing and physical filtration work together to ensure high - quality oil production. Mechanical pressing is responsible for squeezing out the oil from soybeans, while physical filtration removes impurities in the oil. The principle is to use the difference in physical properties between oil and impurities to separate them. In practice, it is necessary to choose the appropriate filter medium and filtration method according to the particle size and nature of impurities. For example, for fine impurities, a filter with a smaller pore size should be selected.
Different oilseeds such as peanuts and palm oil have different physical and chemical properties. Therefore, when using the same equipment, it is necessary to adjust the parameters accordingly. For example, peanuts have a higher oil content and a harder texture compared to soybeans. When pressing peanuts, a higher pressure and a longer pressing time may be required. Palm oil has a high melting point, so a higher temperature is needed during the pressing process to ensure the fluidity of the oil.
Let's take the actual application of the full - automatic multi - functional oil press of Penguin Group as an example. In a real - world scenario, a small - sized oil enterprise used Penguin Group's oil press. After optimizing the equipment parameters, the oil yield increased by 10% compared to the previous level, and the energy consumption decreased by 15%. The data shows that through parameter optimization and the use of advanced equipment, small and medium - sized oil enterprises can achieve the dual goals of stable production and high - quality oil products.
