Modules for extraction of vegetable oils

The extruding and pressed system for the extraction of oil is a process used to obtain oil from seeds with high fat content such as soybean, sunflower, rapeseed, canola, etc. Below, I explain what is in each stage:

Extruding: involves the use of a extruder, which is a specialized machine. The seeds are fed into the extruder, where they undergo high temperatures and high pressures controlled. This combination of heat and pressure helps to break down the cells of the seeds and release the oil contained within.

During the extruding, also produces a deactivation of enzyme that reduces the activity of the enzymes present in the seeds, which is beneficial for the quality of the oil end.

Pressing: After the stage of extrusado, the material extruded is directed to the oil press. The press exerts pressure on the material to remove the residual oil present in the solid residues resulting from the extrusado. This pressing process is performed through the use of screws, or plates that compress the material and separate the oil from the solid mass.

The oil that is produced is collected through channels or ducts, and is separated from the solid waste, usually called cakes, that are ejected from the press.

The system extruding and pressing is widely used because of its efficiency in the extraction of oil and that can adapt to different types of seeds with high fat content.

This method for the extraction of oil offers several advantages in comparison with other methods of extraction:

1. Higher yield of extraction: The extruding and pressing process allows to obtain a higher yield of oil extraction in comparison with other methods. The combination of the extruding stage, that breaks down the cells of the seeds, and the pressing stage, which applies pressure to extract the residual oil, allows you to make more efficient use of the fat content of the seeds.

2. Best quality of oil: The extruding and pressing method is smooth and controlled, which helps to preserve the quality of the oil. The use of temperatures and pressures are moderate, minimizes the degradation of the oil and retain its nutritional properties and organoleptic characteristics.

3. Less use of solvents: unlike other extraction methods, such as extraction with chemical solvents, the extruded and pressed method does not require the use of additional solvents.This makes it a more natural choice, and free of chemical residues.

4. Increased food security: The extruding and pressing process helps to reduce the enzymatic activity and removes potential pathogens present in the seeds. This contributes to greater food security by minimizing the risks of microbiological processes.

5. Versatility in the extraction: The extruding and pressing method can be adapted to different types of seeds with a high fat content, such as soybean, sunflower, rapeseed and canola oil. This provides flexibility in the production of oil from different raw materials.

These advantages make the extruding and pressing method an attractive option for oil extraction, especially for those who value the efficiency, quality and safety in the extraction process.
