Introduction
Peanut oil, a widely favored cooking oil variety among consumers, enjoys steadily growing market demand. Investing in peanut oil extraction machine offers promising market prospects and investment returns.
Based on extraction principles, peanut oil production mainly divides into pressing and solvent extraction. The pressing method is more popular in the market due to its natural physical properties, which better preserve the oil's inherent flavor and nutritional components.

6 Steps Peanut Oil Production Process
The complete peanut oil processing involves six stages: raw material pretreatment, crushing and dehulling, flaking and cooking, pressing, crude oil filtering, and oil refining. Each stage has specific process requirements and dedicated equipment, which together form a complete peanut oil production line.
Raw Material Cleaning and Pretreatment
Before entering the processing stage, peanut raw materials must go through cleaning and pretreatment. This stage mainly uses cleaning screen and stone remover to remove impurities, dirt, stones, and metal fragments from peanuts.
These machines effectively separate impurities through a combination of vibrating screen and air separation principle, protecting subsequent equipment from damage.
Pretreated peanuts also need moisture adjustment. Drying equipment controls peanut moisture content to below 4%. This reduces moisture's negative impact on oil quality and creates favorable conditions for subsequent red skin removal.
Crushing and Dehulling
Pretreated peanuts need dehulling because substances in peanut skins affect oil taste and quality. This stage uses dehulling machine and crushing machine.
First, cool peanut kernels to room temperature, then use dehulling machine to remove red skins. Next, use crushing machine to break them into 3-5mm peanut particles. Crushed peanut particles increase surface area, improving pressing efficiency.
Research shows, control crushing particle size proves crucial for improving oil yield. Particles are too large result in incomplete oil extraction, and particles are too small easily cause gelatinization, affecting oil quality.
Rolling and Cooking
Crushed peanut particles need rolling and cooking treatment. Rolling machine uses roller to press peanut particles into thin flakes, destroying cell structure to facilitate oil release.
Then, cooker heat-treat peanut flakes, typically maintaining 55-60°C, adding water to adjust flake moisture to 8-12%, and steaming for 15-20 minutes.
Precise temperature and humidity control during cooking is very important, directly affecting protein denaturation and increasing oil fluidity.
Oil Pressing
Pressing is the core stage of peanut oil extraction, mainly using screw oil press. Henan Huatai Group's large screw oil press maintains working temperatures of 45-50°C, extracting oil from peanut flakes through mechanical pressure.
Screw oil presses work by using rotating screw shafts to push materials forward. The space gradually decreases, generating enormous pressure that separates oil from peanut flakes.
This equipment features large processing capacity, low power consumption, and low operating costs. The pressed cake maintains a loose but intact structure, allowing easy solvent penetration and low residual oil rates. Pressing produces two parts: preliminary pressed peanut oil and peanut meal.

Crude Oil Filtering
Crude peanut oil from oil presses contains solid particles and impurities, need filtration and purification. This stage mainly uses centrifugal filter or vacuum filter, separating oil residue from oil through centrifugal force or vacuum negative pressure.
Modern filtering machines achieve continuous operation with automatic residue discharge, improving filtration efficiency. Filtered peanut oil becomes basically clear and can meet primary edible standards. However, achieving higher quality grades requires further refining.
Oil Refining
High-quality peanut oil needs refining treatment. Refining equipment includes degumming machine, deacidification machine, decolorization machine, and deodorization machine. (Related Product: Soybean oil refining machine >>)
The refining process removes free fatty acids, phospholipids, pigments, and off-flavor substances from oil, improving oil's smoke point, stability, and shelf life.
Small-scale refining equipment costs about $25,000, meeting the needs of small to medium-sized peanut oil processing plants. Refined peanut oil displays bright color, pure flavor, low acid value, and good stability, meeting national first-grade oil standards.
