Overview of the Full Refining Process

The journey from crude palm oil to refined, edible oil involves a series of crucial steps. Understanding the technical logic behind these steps is essential for efficient and high - quality production. The key steps include degumming, deacidification, decolorization, and deodorization. Each step plays a vital role in transforming the raw, unrefined oil into a clean, stable, and market - ready product.

Detailed Explanation of Technical Parameters in Each Link

For degumming, the temperature usually ranges from 60 - 70°C, the vacuum degree is around 20 - 30 mbar, and the additive dosage is about 0.1 - 0.3% of the oil volume. In deacidification, the temperature can reach 70 - 90°C, the vacuum degree is approximately 10 - 20 mbar, and the additive amount varies according to the acid value of the crude oil. During decolorization, the temperature is maintained at 90 - 110°C, the vacuum degree is 5 - 10 mbar, and the amount of adsorbent used is about 1 - 3%. For deodorization, the temperature can go up to 200 - 240°C, the vacuum degree is less than 1 mbar, and steam is used as an important medium.

Analysis of Common Quality Problems and On - site Troubleshooting Methods

Common quality issues such as abnormal color and excessive free fatty acids can occur during the refining process. Abnormal color may be caused by improper decolorization, such as incorrect temperature or insufficient adsorbent. Free fatty acids may exceed the standard due to incomplete deacidification. On - site troubleshooting methods involve checking the process parameters, inspecting the equipment for leaks or malfunctions, and analyzing the quality of the additives used.

The Role and Advantages of Stainless Steel in Preventing Metal Contamination

Stainless steel is the ideal material for palm oil refining equipment. It has excellent corrosion resistance, which can prevent metal ions from leaching into the oil and causing contamination. Compared with other materials, stainless steel can maintain its integrity and stability in the harsh environment of high - temperature and chemical - rich refining processes, ensuring the purity and safety of the palm oil.

How the Automated Control System Ensures Product Consistency and Production Efficiency

The automated control system is a game - changer in palm oil refining. It can precisely control the temperature, vacuum degree, and additive dosage in each process, eliminating human errors. This leads to consistent product quality from batch to batch. Moreover, it can adjust the operation parameters in real - time according to the changes in the raw material quality, improving the production efficiency and reducing production costs.

Guide to Building Standardized Operating Procedures and Practical Suggestions

Building a standardized operating procedure is crucial for stable production. It includes clear instructions on equipment operation, process parameter setting, and safety precautions. Practical suggestions involve regular training for operators, regular equipment maintenance, and strict quality control at each stage of the production process.

Case Sharing: Typical Customer Problem - Solving Paths and Effect Feedback

One of our customers had problems with inconsistent product quality, with color and free fatty acid content fluctuating from batch to batch. By analyzing the process data and on - site inspection, we found that the problem was due to improper operation of the decolorization and deacidification equipment. We adjusted the process parameters, optimized the equipment operation, and trained the operators. After these measures, the product quality became stable, and the production efficiency increased by 20%.
