The edible oil contains a small amount of wax, which can increase the cloud point, reduce the transparency and digestion and absorption rate of the oil, and make the taste worse, thereby reducing the edible quality, nutritional value and industrial use value of the oil .

Removing or extracting wax from edible oil can achieve improve the quality of edible fats and comprehensively utilizing vegetable fat wax sources.

Winterization system is mainly used to separate wax from oil by low temperature crystallization.

Dewaxing methods: conventional method, solvent method, surfactant method, combined degumming, deacidification method, etc.

An Oil Dewaxing Plant is designed to remove waxes and other high-melting point substances from edible oils, enhancing their clarity and quality. This process is especially crucial for oils that solidify at lower temperatures, such as sunflower oil, corn oil, and rice bran oil, ensuring they remain clear even when refrigerated.

Process of an Oil Dewaxing Plant:

1. Pre-treatment:
   The oil is filtered to remove impurities and prepared for crystallization.

2. Crystallization:
   The oil is cooled under controlled conditions, allowing waxes and high-melting-point fats to crystallize.

3. Filtration:
   Using specialized filters, wax crystals are separated from the oil, producing clear, dewaxed oil.

4. Temperature Control:
   Precise temperature management ensures optimal crystallization without compromising oil quality.

5. Energy Efficiency:
   Modern dewaxing plants incorporate energy-saving mechanisms, such as heat exchangers and insulated systems.

Benefits of Oil Dewaxing:

• Improved Appearance: Ensures a crystal-clear oil, enhancing its visual appeal.
• Extended Shelf Life: Dewaxed oils resist clouding and sedimentation, especially at low temperatures.
• Enhanced Taste: Removes waxes that can impart an undesirable taste.
• Marketability: Meets stringent quality standards required for premium edible oils.
•
