Generally speaking, the oil content of palm kernels is 50-55%. When the residual oil ratio is less than 7%, 0.43-0.48 tons of palm kernel oil can be obtained by pressing 1 ton of palm kernels. Conversely, one ton of palm kernel oil needs to press 2-2.3 tons of palm kernels.In theory, this should be the case, but there are other factors that can affect this result.Let's explore these factors together.
First of all, the oil content of palm kernels varies slightly depending on the place of origin.Therefore, the place of origin must be determined first.
The second factor is equipment. The quality of the equipment directly determines the oil output of palm kernels. Palm kernels are harder. If they are pressed with a conventional oil press, it will reduce the oil yield and cause equipment wear. Therefore, it is necessary to use a special oil press for pressing palm kernels. For small scale palm kernel oil pressing machine, the best-selling is 500kg/h palm kernel oil expeller, which is designed by our company to process palm kernels especially. As the palm kernel is harder, it requires higher hardness of the equipment and also requires stronger pressure. Therefore the pressure of the chamber is further increased, so as to achieve the efficiency of oil extraction and reduce the dry cake oil residue rate. Also the vulnerable parts are made of high-quality alloy steel, which can meet the hardness requirements and significantly improve the machine working life. Besides, our machine has been tested for many times, and the residual oil rate is less than 7%. The low residual oil rate guarantees the interests of customers.
The last is auxiliary equipment. In order to increase the oil yield, some auxiliary equipment needs to be used to make the palm kernel reach the best pressing state before pressing. Auxiliary equipment includes nut grading machine, cracker, crusher and cooker. Taking the cooker as an example, the cooker can adjust the temperature and moisture, increase the oil yield of palm kernels, improve the quality of oil and reduce equipment wear. 
In order to increase the oil yield of palm kernels, all the above factors should be taken into consideration.
