In the realm of small and medium-sized oil mills, selecting the right screw oil press is crucial for enhancing production capacity and oil quality. This article delves into the core technical indicators of these machines, providing valuable insights for oil mill operators.
The design of the screw shaft plays a pivotal role in the material propulsion efficiency and oil output rate. A well-designed screw shaft can ensure a smooth and continuous flow of materials through the press. For example, a screw shaft with an appropriate pitch and diameter can increase the pressure on the materials, thereby improving the oil extraction efficiency. Studies have shown that an optimized screw shaft design can boost the oil output rate by up to 10% compared to traditional designs.
Pressing temperature control is another key factor in optimizing oil quality. Different types of oilseeds have different optimal pressing temperatures. For instance, peanuts are best pressed at a temperature between 110°C and 120°C, while soybeans require a slightly lower temperature of around 100°C - 110°C. By precisely controlling the pressing temperature, oil mills can reduce the degradation of oil components and improve the clarity and flavor of the final product. Advanced temperature control systems can maintain the temperature within a narrow range, ensuring consistent oil quality.
The preheating function in screw oil presses can significantly enhance oil quality and production efficiency. Preheating the oilseeds before pressing can reduce the viscosity of the oil, making it easier to extract. It also helps to break down the cell walls of the oilseeds, releasing more oil. In some cases, preheating can increase the oil output rate by 5% - 8%. Additionally, preheating can improve the color and stability of the oil, making it more marketable.
Small and medium-sized screw oil presses need to be adaptable to different types of oilseeds, such as peanuts, soybeans, and rapeseeds. Each type of oilseed has its own unique physical and chemical properties, which require specific processing parameters. For example, rapeseeds have a high oil content but a hard outer shell, so a press with a higher pressure capacity may be needed. By understanding the characteristics of different oilseeds, oil mill operators can choose the most suitable press for their needs.
When selecting a screw oil press, there are several common mistakes that oil mill operators should avoid. One of the most common mistakes is focusing solely on the price without considering the quality and performance of the machine. Another mistake is underestimating the importance of after - sales service. In terms of energy consumption management, oil mills can adopt energy - efficient technologies, such as using high - efficiency motors and optimizing the pressing process. This can reduce energy consumption by up to 15% - 20%.
