Have you ever wondered how raw oilseeds become the clear, pure cooking oil you use every day? At Henan Huatai Cereals and Oils Machinery Co., Ltd., we specialize in designing and manufacturing complete edible oil processing systems that transform agricultural oilseeds into high-quality bottled oil efficiently and sustainably.
With 38+ years of experience and a presence in nearly 70 countries, Huatai has enabled the production of over 150,000 tons of cooking oil annually—enough to meet the daily needs of 15 million people worldwide.
The Edible Oil Production Process: A Step-by-Step Overview
Using soybeans as an example, let’s explore how Huatai’s equipment facilitates each stage of oil production:
Step 1: Cleaning & Screening
- Soybeans are transported from silos to the processing workshop via elevators and conveyors.
- They undergo:Screening to remove foreign materials
- Magnetic separation to eliminate metal impurities
- Cleaning to ensure only pure, flawless soybeans proceed
Step2: Crushing
- Soybeans are crushed into 4–6 pieces to increase surface area,The detached hulls are removed using an air separator.
Step 3: Softening & Conditioning
- In conditioning pots, moisture and temperature are precisely controlled to achieve optimal elasticity and plasticity for extraction.

Step 4: Flake Pressing
- Crushed soybeans are pressed into thin flakes,increasing surface area to improve oil yield in subsequent stages.

Step 5: Extrusion or Drying
Flakes undergo extrusion or drying to:
- Alter physical structure for better oil release
- Passivate biological activity (e.g., reduce urease levels in meal)
- Enhance overall process efficiency

Step 6: Drying & Cooling
- Using dryers or coolers, moisture and temperature are readjusted to prepare for oil extraction.
Step 7: Oil Extraction
Two primary methods are used depending on the oilseed:
- Physical Pressing: Ideal for high-oil-content seeds like peanuts or rapeseed
- Solvent Extraction: Used for low-oil-content seeds like soybeans; employs food-grade solvents for maximum yield
Step 8: Refining & Packaging
Crude oil undergoes refining processes, including:
- Degumming, deacidification, decolorization, and deodorization
- Final packaging into clear, safe, and market-ready cooking oil
