How to Build a Corn Germ Oil Processing Plant at Low Cost?

Looking to enter the healthy edible oil market but worried about high investment and slow returns?Corn germ oil might be the golden opportunity you’ve overlooked: the raw material is almost cost-free, while the selling price of refined corn oil in international markets is typically 30% higher than regular vegetable oils. Whether you plan to start with a small trial line or expand to a mid- or large-scale facility, a corn germ oil processing plant can help you enter this high-margin industry at a relatively low investment.

1. Market Potential: Rapid Growth of Healthy Oils

• Rising demand: Corn oil is rich in Vitamin E and linoleic acid (about 55%), which supports heart health and helps lower cholesterol. In Europe and the U.S., corn oil often sells at a 30–40% premium compared with ordinary cooking oils.

• Raw material advantage: Corn germ is a by-product of the starch industry. From 100 tons of corn, about 7 tons of germ can be extracted, making the feedstock supply cost almost negligible.

• Market gap: In many regions, local production cannot meet demand, and dependence on imports is high—creating a significant opportunity for new investors.

2. Key Strategies to Control Costs

(1) Equipment Selection – Flexible by Scale

✅ Cost-saving tips:

• For small-scale investors, choose a corn germ oil pressing machines.

• For medium-scale plants, the “pre-press + solvent extraction” process significantly improves oil yield and reduces long-term production costs.

(2) Factory and Labor

• Factory Size: 200–500㎡ is enough for a small corn germ oil plant.

• Labor: A pressing line needs only 3 workers; a solvent extraction line requires 5–8 workers.

(3) Raw Material Sourcing

• Partner directly with corn starch plants to purchase germ.

• Buying germ directly can reduce raw material cost by up to 60%.

3. Recommended Process Routes

Option A: Pressing + Refining (for small-scale investors)

• Process: Germ → cleaning → cooking → pressing → filtering → refining

• Advantages: Lower equipment investment (approx. USD 30,000–50,000), good crude oil quality

• Limitations: Residual oil content of 5–6%, suitable for small-batch production

Option B: Pre-press + Solvent Extraction + Refining (for mid-scale investors)

• Process: Germ → pre-press → solvent extraction → degumming → neutralization → bleaching → deodorization

• Advantages: Residual oil <1%, higher oil recovery, lower production cost at scale

• Limitations: Requires compliant solvent handling, investment typically above USD 150,000
