What Does an Oil Press Machine Do?
An oil press machine is a mechanical device used to extract oil from oil-bearing seeds, nuts, and fruits. What is the oil press machine function? It plays a vital role in both small-scale and industrial oil production. Whether you’re pressing peanuts for cooking oil or extracting flaxseed oil for nutrition, an oil press offers an efficient, solvent-free way to obtain natural oils.

1. The Function of an Oil Press Machine
The core oil press machine function is to apply mechanical force—via a screw, piston, or hydraulic system—to break down plant cells and release the contained oil. The process can be categorized into cold pressing and hot pressing, depending on whether heat is applied during extraction.
Cold pressing preserves the oil’s natural aroma, color, and nutrients, making it popular for premium edible oils and cosmetics. Hot pressing uses heat to increase yield and is preferred in industrial-scale operations where maximum output is the goal.
2. What Materials Can Be Pressed?
Oil press machines can handle a wide variety of raw materials. Below are some commonly used oilseeds and their average oil content:
| Raw Material | Typical Oil Content (% by weight) |
|---|---|
| Sunflower Seed | 40–45% |
| Peanut (Groundnut) | 40–50% |
| Rapeseed (Canola) | 35–45% |
| Sesame Seed | 45–50% |
| Soybean | 18–20% |
| Coconut (Copra) | 60–65% |
These materials can be processed using different press types (screw, hydraulic, cold, or hot) depending on oil characteristics, processing needs, and quality goals.
