Dingsheng Machine: Advanced Oil Refining Solutions – Decolorization Process
Date:Nov 11th, 2024
The goal of oil decolorization is not to remove all pigments but to improve oil color and prepare it for deodorization. This step also prevents color reversion, enhances the shelf life of the refined oil, and improves its quality and marketability.
Features of Decolorization Equipment
High-Quality Manufacturing: Built to meet premium standards for reliability and durability.
Uniform Stirring: Ensures efficient mixing and easy cleaning.
User-Friendly Controls: Temperature settings adjustable with simple button operation.
Durable Construction: Resistant to acid, alkali, and corrosion, with rapid heating capabilities.
Why is Decolorization Essential?
Edible oil is mainly composed of triglycerides, which are naturally colorless in liquid form and white when solid. However, crude oil contains various pigments, including:
Organic Pigments: Such as chlorophyll, carotenoids, and gossypol.
Degraded Organic Substances: Including proteins, carbohydrates, and phospholipids.
While not all pigments are harmful, some can degrade oil quality or pose health risks, making their removal critical during refining.
Common Methods for Oil Decolorization
Adsorption Decolorization:
The most commonly used method in oil refining.
Relies on substances like bleaching earth, activated clay, or activated carbon to adsorb pigments and impurities.
Effectively removes trace metals and harmful substances, setting the stage for further refining processes such as hydrogenation and deodorization.
Heat Decolorization:
Uses thermal denaturation to remove heat-sensitive pigments.
Best suited for low-value oils like palm oil and coconut oil but is not recommended as a standard refining process due to potential thermal oxidation of oils.
Oxidation Decolorization:
Utilizes the instability of pigments like carotenoids and chlorophyll under oxidation.
Ideal for auxiliary decolorization in high-carotenoid oils like palm oil but must be controlled to avoid thermal oxidation.
Chemical Reagent Decolorization:
Employs oxidizing agents such as sodium dichromate, hydrogen peroxide, or ozone.
Effective for pigment removal, but strict control of process conditions is required to minimize chemical residues.
Advantages of Dingsheng Machine Decolorization Equipment
Precision Engineering: Designed to handle a variety of oils with consistency and efficiency.
Enhanced Safety: Built to minimize chemical residues, ensuring compliance with food safety standards.
Customizable Solutions: Tailored to meet specific customer needs for optimal performance.
Comprehensive Support: End-to-end service from design to after-sales assistance.
