Differences between palm oil pressing and palm kernel oil pressing

In the complex edible oil market, palm oil and palm kernel oil are two major products, each with unique production processes, characteristics and applications. As a leading expert in the oil and fat industry, Henan Glory Oil and Fat Engineering Co., Ltd. will explain the differences between palm oil pressing and palm kernel oil pressing in detail to help you make an informed decision based on your business needs.

1. Difference of Source and Composition

(1) Palm Oil: It is extracted from the oil palm fruit. The palm fruit is rich in oil and contains fewer fibers, making it easier to process. It is rich in palmitic acid, which makes it semi-solid at room temperature. Palm oil has a balanced ratio of saturated and unsaturated fats, making it suitable for a variety of food and industrial applications.

(2) Palm Kernel Oil: It comes from the kernel or seed inside the palm fruit. It contains higher levels of lauric acid, which gives it a firm texture and unique chemical properties. The composition of palm kernel oil is more similar to coconut oil, with a higher saturated fat content than palm oil.

2. Difference of Pressing Process

(1) Palm Oil Pressing: The palm oil pressing process is very complex. First, the fresh palm fruit bunches are sterilized to prevent enzyme activity from causing the oil to deteriorate. After sterilization, the palm fruit bunches are threshed to separate them from the bunches. The pulp is then digested to break the cell walls and release the palm oil. Crude palm oil is usually extracted from the digested pulp using mechanical pressing or screw pressing. This crude palm oil still contains impurities such as fiber, moisture and free fatty acids and needs to be refined through processes such as degumming, deacidification, decolorization and deodorization to meet the quality standards of various applications.

(2) Palm Kernel Oil Pressing: Due to the hardness of palm kernels, palm kernel oil extraction equipment needs to have stronger crushing and grinding capabilities. Equipment such as palm kernel crushers are usually used to crush palm kernels into smaller particles. The palm kernel oil pressing process begins with drying the palm kernel to reduce its moisture content. This makes the palm kernel easier to handle and improves the oil extraction efficiency. After drying, the palm kernel is then pressed to obtain a large amount of palm kernel oil. Similar to palm oil, the obtained crude palm kernel oil also needs to be refined.

3. Difference of Pressing Equipment

(1) Palm Oil Pressing: Taking Henan Glory Company as an example, the equipment usually equipped for palm oil pressing is a palm oil press equipment, which is specially used for palm oil pressing and cannot be used to press other oils. According to the different processing capacities, palm oil press equipment is divided into single screw palm oil press equipment and double screw palm oil press equipment. Among them, the single screw palm oil press equipment manufactured by Henan Glory Company have two power options: motor and diesel engine. They are very suitable for home use and small investors.

(2) Palm Kernel Oil Pressing: It is usually equipped with a single screw palm kernel oil press equipment. In addition to being used to press palm kernels to extract palm kernel oil, it can also be used to press other oils such as sunflower seeds, soybeans and peanuts. It is not only wear-resistant, but also easy to operate.

To sum up, the main difference between palm oil pressing and palm kernel oil pressing is that the pressing process and the equipment required are different. Understanding the difference between the two is essential to optimizing the production, sustainability and market positioning of palm oil and palm kernel oil.
