How to Work the Palm Oil Bleaching Process?
As one of the most widely used vegetable oils in the world, the bleaching process in the palm oil refining process is crucial. Henan Huatai Cereals and Oils Machinery Co., Ltd., as one of the leading enterprise in China’s grain and oil machinery industry, has 37+ years of rich experience in the field of palm oil equipment manufacturing. In this article, Huatai will introduce the complete process of palm oil bleaching process in detail and introduce our technical advantages in this field.
Overview of palm oil bleaching process
Palm oil bleaching is a key link in the palm oil refining process. The main purpose is to remove pigments, residual soap particles, metal ions and other impurities in the oil. The bleaching process developed by Henan Huatai Cereals and Oils Machinery Co., Ltd. adopts the principle of physical adsorption and uses efficient decolorization equipment to make the palm oil reach the ideal color and quality.
Detailed explanation of the palm oil bleaching process
1) Pretreatment stage
Before entering the palm oil bleaching process, the pretreatment system designed by Huatai Oil Machinery will first degumming and deacidify the crude oil to ensure that the oil entering the bleaching tower meets the process requirements.
2) White clay addition system
The automatic white clay addition system of Huatai Oil Machinery can accurately control: the amount of white clay added (usually 1-3% of the oil weight), the addition speed and the mixing uniformity
3) Bleaching reaction process
In the bleaching tower designed by Huatai Oil Machinery, the oil-soil mixture reacts under the following conditions:
Temperature: 100-110℃
Vacuum: absolute pressure ≤8kPa
Time: 20-30 minutes
4) Filtration separation
After the reaction is completed, Huatai high-efficiency leaf filter or vertical filter press is used for solid-liquid separation, and the white clay residue can be controlled below 50ppm.
5) White clay recovery and processing
Huatai Oil Machinery provides a complete white clay recovery system to achieve resource reuse and reduce palm oil production costs.
