Rotary Oil Extraction Machine

Product Description

How It Works

1. Feeding: Raw materials (like soybeans, sunflower seeds, or peanuts) are fed into the machine.
2. Crushing: The materials are first crushed or flaked to increase the surface area, making it easier to extract the oil.
3. Heating (optional): Some machines have a heating element to preheat the materials, which can help improve oil yield and reduce extraction time.
4. Extraction: The core process involves a rotary mechanism”often a screw or a similar component”that presses or squeezes the oil out of the crushed materials. The rotary action helps to apply continuous pressure.
5. Filtration: The extracted oil may be filtered to remove solid particles and impurities.
6. Collection: The filtered oil is collected, while the remaining solid material (called cake or residue) is discharged.

Types

1. Cold Press: Extracts oil without applying heat, preserving more nutrients and flavors.
2. Hot Press: Uses heat during extraction, which can increase yield but may affect flavor and nutritional quality.
3. Expeller Press: Uses a mechanical screw to press oil from seeds. It's a common type of rotary machine.
