Edible Oil Refining Plant Equipment

Crude vegetable oil obtained from oil mills via pressing or solvent extraction contains various non-glyceride impurities—such as free fatty acids, phospholipids, pigments, waxes, and odorous compounds. To turn this crude oil into clear, stable, and healthy cooking oil, a complete edible oil refining plant equipment line is required.

Huatai designs, manufactures, and installs complete cooking oil refinery machines for global oil mill processors. Whether you refine soybean oil, sunflower oil, palm oil, peanut oil, or rice bran oil, our customized EPC solutions maximize your product quality, reduce oil losses, and optimize thermal energy efficiency.

The 4 Essential Stages of Edible Oil Refining

A complete industrial edible oil refining plant seamlessly integrates four primary chemical and physical purification stages:

1. Degumming Section (Removal of Phospholipids)

Utilizes the hydrophilic nature of gums. By introducing a precise amount of hot water or phosphoric acid, phospholipids swell, agglomerate, and are separated cleanly via centrifugal disc separators.

2. Deacidification / Neutralization Section (FFA Removal)

Chemical Method: Adds lye ( $\text{NaOH}$ ) to neutralize Free Fatty Acids (FFA), generating soapstock which is then separated out.
Physical Method: Uses a structured packing deacidification tower under high vacuum and heat to strip out fatty acids via steam distillation—ideal for palm and coconut oils.

3. Decolorization / Bleaching Section (Color Pigment Removal)

Crude oil is mixed with activated clay or bleaching earth under a strict vacuum environment. The porous clay adsorbs chlorophyll, carotenoids, and trace metal ions, which are subsequently filtered out by automatic leaf filters.

4. Deodorization Section (Odorous Compounds & Stripping)

Operated under extreme high vacuum ( $2 - 4 \text{ mbar}$ ) and high temperatures ( $230^\circ\text{C} - 250^\circ\text{C}$ ). Injection of direct stripping steam carries away volatile odorous compounds, aldehydes, ketones, and thermal degradation elements, ensuring a bland, odor-free final oil.

(Note: For high-wax oils like sunflower, corn, or rice bran oil, a fifth Dewaxing / Winterization section is seamlessly integrated to prevent cloudiness at low temperatures.)

Technical Classifications of Refinery Systems

Huatai customizes the automation level and structural footprint of your edible oil refining plant equipment based on your target daily production capacity:

Refinery Plant Type	Daily Processing Capacity	Best Suited For	Key Engineering Features
Batch / Intermittent	$1 - 10 \text{ TPD}$ (Tons Per Day)	Small oil mills, specialty seeds, low initial budgets	Small footprint, highly flexible for switching between different oilseeds, easy manual/button control.
Semi-Continuous	$15 - 50 \text{ TPD}$	Growing medium-sized processing plants	Combines batch degumming/bleaching with continuous physical deacidification and deodorization.
Fully Continuous	$> 50 \text{ TPD}$ $3,000 \text{ TPD}$	Large-scale commercial oil refining groups	Fully automated PLC/DCS centralized control, minimum labor footprint, ultra-low oil loss, and deep heat recovery.
