What preparations should be done before squeezing palm kernel oil?

In addition to being directly edible, palm kernel oil is also widely used in fried foods, so the demand is increasing. When many palm kernel oil manufacturers first understand the production process, they want to know what preparations palm kernel should do before pressing?

First of all, palm kernels are obtained from palm nuts. Since palm kernels are very hard, there is no machine that can directly squeeze them to obtain palm kernel oil. Even if it can, the oil yield is very low, which is a waste of raw materials. Therefore, before squeezing the palm kernel, the outer shell of the palm kernel needs to be removed first. There are many small local workshops in Nigeria that require manual peeling or crushing of palm kernels directly with a crusher, but the palm kernels obtained in this way are difficult to separate from the shells, and the work efficiency is very low. Therefore, in order to meet the needs of customers, the core separation system we designed consists of a sheller and a Cyclone separation column. Our sheller adjusts the distance between the tooth plate and the beating rod to adapt to different sizes of palm cores. The palm nucleus continuously jumps and collides between the tooth plate and the beating rod to realize the fragmentation of the shell and retain the integrity of the kernel. The palm kernels and shells obtained in this way have a relatively large difference in specific gravity, and then the interaction between the Cyclone separation column and the fan is used to suck away the lighter shells, leaving the heavier palm kernels to achieve kernel-core separation.

After the complete palm kernel is obtained, because the palm kernel is relatively hard, the palm kernel should be crushed to 4-6 petals before pressing, which can help the subsequent wok to adjust the palm kernel moisture and temperature, and can also reduce the work of the oil press Pressure to extend the service life of the oil press. After crushing, the palm kernel needs to be adjusted in temperature and moisture. The water content of the palm kernel before entering the oil press cannot be higher than 10%, otherwise the oil will stick to the roller during the pressing process, which will affect the use of the machine, and it will be steamed and fried. In the future, palm kernels are easier to produce oil, with a higher oil yield, reducing the working pressure of the oil press, ensuring the maximum extraction of kernel oil and avoiding material waste.

The above is the preparation that palm kernels need to do before pressing, and I hope to provide beneficial help to those interested in palm oil business.

Single screw palm kernel oil press machine

Single screw palm kernel oil expeller machine is an advanced oil expeller machine which retains the benefits of traditional oil press with sturdier structure and adds an automatic heater for hot extrusion that increases the rate of oil output. The Model palm kernel oil expeller machine has large capacity and reliable performance and it is suitable for small farms of 3-15 hectares, processing with supplied materials from outside for individual household or pre-pressing in submerging oil workshops. It is favored by large and medium-sized oil extrusion workshops due to its advantages that of economical and practical. The palm kernel oil expeller can be used to process seeds from a variety of oil plants and enjoys great popularity among customers in Africa and South America.

Main Process of Mechanical Extraction for Palm Kernel Oil Processing

Mechanical extraction processes are suitable for both small and large capacity operations with palm kernel oil expeller machine. Below are the three basic steps of palm kernel oil extraction:

Separating of fiber and nuts - cracking - separating of kernel and shell - crushing - cooking - pressing - palm kernel oil

Cakes discharged from the palm kernel oil expeller would be processed by the cake breaker for separating of the slag and kernels. Then, centrifugal shelling is made to shell the palm nut and get net palm kernel. Proper pre-treatment of palm kernel is necessary to extract the oil from the kernels efficiently. The feed kernels must first be cleaned of foreign materials that may cause damage to the palm kernel oil  expeller. Then, the palm kernel would be milled into small particles and heated and pressed by the palm kernel oil expeller. The raw palm oil is purified with a filter press and filled for selling.
