Small and medium-sized oil and fat enterprises often face a myriad of challenges. Low oil extraction rates mean less product output from the same amount of raw materials, directly affecting profitability. High energy consumption not only increases production costs but also goes against the trend of sustainable development. Moreover, unstable product quality can lead to customer dissatisfaction and loss of market share. These issues have long been a headache for the industry, but there is a solution on the horizon.
The peanut oil pressing process starts with pre - treatment. This involves cleaning the peanuts to remove impurities such as dirt, stones, and broken kernels. After that, the peanuts are usually roasted to enhance the flavor and make the oil easier to extract. The next step is the actual pressing. The roasted peanuts are fed into the press, where mechanical force is applied to squeeze out the oil. Finally, the crude oil is filtered and collected. Each of these steps is crucial, and any misstep can affect the final quality and quantity of the oil.
The key to high - efficiency peanut oil pressing lies in the synergistic effect of mechanical pressing and physical filtration. Mechanical pressing uses powerful forces to break the cell walls of the peanuts and release the oil. Physical filtration, on the other hand, removes impurities from the crude oil, ensuring its purity. By combining these two methods, the oil recovery rate can be significantly increased, and the purity of the oil can be guaranteed. For example, in some experiments, the combination of these two methods has increased the oil recovery rate by up to 15% compared to traditional methods.
Different oilseeds have different characteristics, so the parameters of the pressing equipment need to be adjusted accordingly. For peanuts, a pressure of around 30 - 50 MPa, a temperature of 80 - 100°C, and a pressing time of 30 - 60 minutes are generally recommended. For soybeans, the pressure can be slightly lower, around 20 - 40 MPa, and the temperature can be around 70 - 90°C. By carefully adjusting these parameters, the oil extraction efficiency can be maximized while minimizing energy consumption.
Let's take a look at a real - world example. A small - medium - sized enterprise started using the oil press from Penguin Group. Before using the new equipment, their peanut oil extraction rate was only about 40%. After implementing the new technology and using the Penguin Group's oil press, the extraction rate increased to 55%. This significant increase in the extraction rate not only improved the company's profitability but also enhanced its competitiveness in the market.
To reduce losses and extend the service life of the equipment, some operation skills can be adopted. For example, regular maintenance of the equipment can prevent breakdowns and ensure its normal operation. In addition, optimizing the pre - treatment process can reduce the load on the pressing equipment and improve the overall efficiency. By following these suggestions, enterprises can achieve more stable and efficient production.
In conclusion, the efficient peanut oil pressing technology that combines mechanical pressing and physical filtration offers a promising solution for small and medium - sized oil and fat enterprises. It can help them overcome the industry pain points, achieve high - quality oil production, and improve their competitiveness in the market.
