This article focuses on the key technologies and core considerations for small and medium - sized oil production enterprises when selecting oil extraction equipment. It systematically analyzes factors such as extraction efficiency, equipment energy consumption, ease of operation, suitable oilseed types, multi - function integration, and equipment material quality.
According to industry reports, in recent years, the global demand for vegetable oils has been increasing at an average annual rate of about 3%. Small and medium - sized oil production enterprises are facing increasing competition. Choosing the right oil extraction equipment is crucial for them to improve production efficiency and reduce costs.
Improving extraction efficiency is the primary goal of oil extraction equipment selection. Advanced technologies such as screw pressing and hydraulic pressing have been widely used. For example, some high - efficiency screw presses can increase the oil extraction rate by 5 - 10% compared with traditional equipment. By optimizing the screw structure and pressing process, the contact area between the oilseed and the pressing mechanism is increased, thereby improving the extraction efficiency.
Energy consumption is an important cost factor for oil production enterprises. Modern oil extraction equipment often adopts energy - saving designs, such as using high - efficiency motors and intelligent control systems. According to statistics, energy - saving oil extraction equipment can reduce energy consumption by 15 - 25%, which can significantly reduce the operating costs of enterprises in the long run.
The ease of operation of oil extraction equipment directly affects the labor intensity and production efficiency of workers. Intelligent oil extraction equipment with touch - screen control and automatic fault diagnosis functions can greatly simplify the operation process. For example, some equipment can automatically adjust the pressing parameters according to the type and moisture content of the oilseed, reducing the need for manual intervention.
Different oilseeds have different physical and chemical properties, so the oil extraction equipment needs to be technically matched. For example, peanuts have a high oil content and relatively hard shells, so they require equipment with high pressing force; while soybeans have a lower oil content and are more suitable for equipment with a pre - pressing and leaching process. Matching the right equipment with the oilseed can improve the oil extraction rate and oil quality.
Multi - function oil extraction equipment can process multiple types of oilseeds and perform different oil extraction processes, which is very suitable for small and medium - sized enterprises with limited production scale. For example, a multi - function oil extraction machine can not only press oil but also perform oil refining and filtering, reducing the need for multiple pieces of equipment and saving production space and cost.
The material of the oil extraction equipment has a significant impact on its service life and the quality of the extracted oil. High - quality stainless steel materials can prevent corrosion and ensure the hygiene of the oil. For example, equipment made of 304 stainless steel has a longer service life and can better maintain the purity of the oil.
In addition to the above factors, the service support and after - sales guarantee of the equipment supplier are also very important for purchasing decisions. A reliable supplier can provide timely technical support and spare parts supply, ensuring the long - term stable operation of the equipment.
