Core Technology of Palm Oil Bleaching, Deodorization and Deacidification Process and Equipment
As one of the most important vegetable oils in the world, the decolorization, deodorization and deacidification links in the palm oil refining process directly determine the quality and market value of the final product. Henan Huatai Cereals and Oils Machinery Co., Ltd. has formed a unique technical advantage in the field of palm oil refining equipment with 37+ years of experience in the research and development of oil processing equipment. This article will deeply analyze the key technologies and equipment characteristics of the three core links in the palm oil refining process.
Core technology of palm oil decolorization equipment
1) Palm oil bleaching process principle

High-efficiency capture system: recover fatty acids up to 99%
Waste heat recovery device: energy saving more than 20%
3) Guarantee of deodorization effect
After being treated by Huatai deodorization equipment:
Free fatty acids ≤0.05%
Peroxide value ≤1.0meq/kg
Flavor score ≥8 points (10 points)
Trans fatty acid increment ≤1%
Core technology of palm oil deacidification equipment
1) Physical palm oil deacidification technology
Features of Huatai physical deacidification equipment:
Working temperature 250-270℃
Vacuum degree 1-2mbar
Using special packing structure
Deacidification efficiency is more than 98%
2) Chemical deacidification technology
Advantages of HT-CDA series chemical deacidification system:
Automatic alkali preparation system: accuracy ±0.1%
High-efficiency mixing device: reaction time is shortened by 30%
Centrifugal separation technology: soap stock oil content ≤20%
Online monitoring system: real-time adjustment of process parameters
Technical advantages of Huatai’s core equipment
1) Material advantages:
The contact material part uses 316L stainless steel
Imported brands are used for key components
Special anti-corrosion treatment extends equipment life
2) Control advantages:
Fully automatic PLC control system
Online quality monitoring system
Remote monitoring and fault diagnosis
3) Energy-saving advantages:
Heat recovery rate ≥ 85%
Steam consumption ≤ 280kg/t oil
Electricity consumption ≤ 25kWh/t oil
4) Environmental advantages:
Wastewater discharge meets national first-level standards
Waste gas treatment efficiency ≥ 99%
Noise control ≤ 75 decibels
Equipment selection recommendations
1) Select according to raw material characteristics
Low acid crude oil (FFA < 5%): physical refining route
High acid crude oil (FFA > 5%): chemical refining route
High pigment crude oil: enhanced decolorization system
2) Select according to production capacity
1-10 tons small palm oil refining unit
10-100 tons medium-sized palm oil refining plant
100+ tons large palm oil refinery
3) Select according to automation needs
Basic type: semi-automatic control, more manual operation
Standard type: PLC automatic control
Intelligent type: fully automatic + remote monitoring + MES system
Maintenance points
1) Daily maintenance:
Regularly check the sealing of the vacuum system
Cleaning the inner wall of the decolorization tower every month
Replace the filter medium every quarter
2) Maintenance of key components:
Replace the lubricating oil of the heat medium pump every year
Maintenance of the vacuum pump every 2000 hours
Instrument calibration every year
3) Overhaul cycle:
Generally, the palm oil equipment is fully overhauled every 3-5 years
The life of the main components is 8-10 years
Conclusion
The decolorization, deodorization and deacidification of palm oil refining are the key links that determine the quality of the final palm oil.
