Selecting the appropriate oil processing method is one of the most critical decisions when establishing an edible oil production plant. The method you choose directly impacts your product quality, target market, production costs, and long-term business viability. With over 38 years of experience in designing and manufacturing oil processing equipment, Huatai Cereals and Oils Machinery Co., Ltd. provides this comprehensive guide to help you make an informed decision.
Understanding the Three Main Oil Processing Methods
1. Cold Pressing
Cold pressing involves extracting oil from oilseeds using hydraulic pressure at low temperatures, typically below 60°C. This mechanical method avoids chemical treatments and high-temperature processing.
Preserves natural nutrients, vitamins, and antioxidants
Maintains the oil's original flavor, aroma, and color
No chemical solvents involved
Ideal for organic and premium product lines
Walnut oil
Flaxseed oil
High-end olive oil
Other specialty and health-focused oils

Targets health-conscious consumers and premium markets where nutritional value and natural qualities are key selling points.
2. Hot Pressing
Hot pressing involves cleaning and crushing oilseeds followed by roasting at high temperatures (typically 100-130°C) before mechanical pressing. The heat treatment enhances oil yield and develops characteristic flavors.
Higher oil yield compared to cold pressing
Develops rich, traditional oil aroma
Familiar flavor profile preferred by many consumers
Cost-effective for medium-scale production
Peanut oil
Sesame oil
Sunflower oil
Other traditional edible oils
Serves the mass market where familiar taste and cost-effectiveness are primary considerations.

3. Solvent Extraction
Solvent extraction uses food-grade solvents (typically hexane) to dissolve oil from oilseeds, followed by refining processes to remove solvent residues and impurities.
Highest oil recovery rate (up to 99%)
Lowest production cost per unit
Suitable for large-scale operations
Produces neutral-tasting oil

Soybean oil
Rapeseed oil
Corn oil
Other high-volume commodity oils
Ideal for price-sensitive mass markets and industrial-scale production.
Key Selection Factors
Premium Health Markets: Cold pressing for nutrient preservation
Mainstream Consumers: Hot pressing for traditional flavor profiles
Price-Sensitive Markets: Solvent extraction for cost competitiveness
Initial Investment: Cold press < Hot press < Solvent extraction
Operating Costs: Vary by scale and energy requirements
Return on Investment: Depends on target market and product pricing
Raw Material Characteristics: Different oilseeds suit different methods
Production Scale: Small (cold press), Medium (hot press), Large (solvent extraction)
Product Portfolio: Many successful plants combine multiple methods
