The Difference between Palm Oil Pressing and Palm Kernel Oil Pressing
In the current edible oil market, palm oil and palm kernel oil each occupy an important position, with unique and complex production processes, characteristics and a wide range of applications. Today, Henan Huatai Cereals and Oils Machinery Co., Ltd. will give you a detailed introduction to the difference between palm oil pressing and palm kernel oil pressing, helping you make a wise choice based on your business needs.
The difference between the source and composition of palm oil and palm kernel oil
(1) Palm oil: Palm oil is extracted from palm fruit. Palm fruit is rich in oil and has a low fiber content, making it easy to process. Palm oil is also rich in palmitic acid and is semi-solid at room temperature. It has a balanced ratio of saturated fat to unsaturated fat and is widely used in various food and industrial fields.
(2) Palm kernel oil: Palm kernel oil is extracted from the kernel of palm fruit. Palm kernel oil is rich in lauric acid and has a firm texture. The composition of palm kernel oil is closer to coconut oil, and its saturated fat content is higher than that of palm oil.
The difference between palm oil pressing and palm kernel oil pressing
(1) Palm oil pressing process: The palm oil pressing process is extremely complicated. First, fresh palm fruit bunches must be sterilized to inhibit the lipase activity in the palm fruit to prevent the free fatty acid content from increasing. After sterilization, the palm fruit bunches must be threshed to separate the palm fruit from the fruit bunches. Then, the palm fruit is passed through a palm oil single and double screw oil press to squeeze out palm oil. However, after pressing, crude palm oil still contains impurities such as pulp fiber. It needs to go through multiple palm oil refining processes such as degumming, deacidification, decolorization, and deodorization to meet the quality standards required for palm finished oil.
(2) Palm kernel oil pressing process: The first step in the palm kernel oil pressing process is to dry the palm kernel to reduce the moisture content of the palm kernel, making it easier to press and improving the oil pressing efficiency. Since the palm kernel is relatively hard, the dried palm kernel also needs to be crushed into smaller particles using a palm kernel crusher. In this way, after the palm kernel is pressed, crude palm kernel oil will be obtained. However, similar to palm oil, the crude palm kernel oil obtained also needs to be refined.
The difference between palm oil press machine and palm kernel oil press equipment
(1) Palm oil pressing equipment: The commonly used pressing equipment is the palm oil press, which is specially designed for palm oil pressing and is not suitable for pressing other oils. According to the different processing capacities, palm oil press can also be divided into two types: palm oil ingle screw press and palm oil double screw press. Among them, the palm oil screw press produced by Henan Huatai Oil Machinery is particularly suitable for use in palm oil pressing production lines.
(2) Palm kernel oil pressing equipment: Palm kernel oil pressing equipment usually chooses a palm kernel oil single screw press. In addition to being used to press palm kernels, palm kernel oil single screw presses can also be used to press other oil crops such as sunflower seeds, soybeans and peanuts. In addition, the screw of the palm kernel oil single screw press is generally made of alloy steel, which has extremely strong wear resistance and is suitable for dealing with the characteristics of high hardness of palm kernels.
In summary, the main difference between palm oil pressing and palm kernel oil pressing lies in the different processes and equipment required. Understanding the differences between palm oil pressing and palm kernel oil pressing is crucial for optimizing the production, sustainability, and market positioning of palm oil and palm kernel oil.
