How to choose edible oil making method?

Pressing or solvent extraction?

Many customers who want to build or invest in oil mills are hesitant about which production method to choose because they don't know much about pressing and solvent extraction processes. In fact, pressing and solvent extraction are two different edible oil production processes.
The choice of production process mainly depends on the oil to be processed. Generally speaking, our common sesame, peanuts, rapeseed and other oil crops with high oil content are mostly selected for pressing in actual production. Oils with low oil content such as soybeans and rice bran are mostly produced by leaching.
This choice is mainly determined by the characteristics of the pressing method and the solvent extraction method. The difference between the pressing method and the leaching method is that the pressing method is to squeeze the oil out of the oil with the help of mechanical force. The oil is directly separated from the oil by physical pressure, and there are no other chemical additives in the whole process to ensure that the health and nutrition of the oil are not destroyed.
Compared with other oil extraction methods, the pressing oil extraction has the advantages of simple process, less supporting equipment, strong adaptability to oil varieties, flexible production, good quality, light color, and good flavor. In actual production, the degree of pressing and the pressure on the material during pressing, the pressed oil can be divided into a pre-pressing with a single pressing and leaching oil extraction, which is widely used.
The extraction method of oil production is to select a suitable solvent to soak or spray the pre-treated oil to extract the oil from the oil. Using the extraction method to make oil, the residual oil in the meal can be controlled below 1%, the oil yield is high, and the quality of the meal is good. Compared with the high residual oil content of the oil cake, high power consumption, and easy wear of parts in the pressing method, the extraction method of oil production has low processing costs and low labor intensity.
When choosing the oil production process, the oil mill should still choose according to its actual situation. There is no difference between extraction oil production and pressing oil production. Extracted oil and pressed oil are both healthy oils that can be eaten after refining.
​Advantages of extraction oil production
High oil yield: For most raw materials, the oil yield of the leaching method is much higher than that of the pressing method, which can make full use of the oil resources in the raw materials and reduce production costs.
​Suitable for large-scale production: The process is relatively mature, the equipment has a high degree of automation, and is suitable for large-scale industrial production.
