Soybean extraction requirement on the materials

Soybean extraction plays a crucial role in obtaining soybean oil, a widely used cooking and industrial oil. To ensure optimal extraction efficiency and achieve a high-quality end product, it is essential to consider the material requirements during the pretreatment stage.

Material Structure and Thickness:

The structure and thickness of the soybean material significantly impact the extraction process. To maximize the efficiency of extraction, the material should be thin and firm with a small powder presence. This characteristic allows for a shorter extracting distance and a larger contact area between the solvent and the soybean particles. For direct extraction, the recommended thickness of the soybean material is between 0.2 to 0.3 mm. This thickness enables effective solvent penetration and facilitates the dissolution of oils.

Moisture Content:

Proper moisture content is another critical consideration when preparing soybean material for extraction. Since the extracting solvent used is insoluble in water, excessive moisture within the material can hinder solvent penetration and the subsequent dissolution of oils. Therefore, it is crucial to maintain low moisture levels in the soybean material. The moisture content should ideally be kept below 13%, with a recommended range of 5 to 7%. By ensuring appropriate moisture levels, the efficiency of the extraction process can be significantly improved.

Temperature Control:

Temperature plays a vital role in soybean extraction, as it influences the viscosity of the oil and the flow characteristics of the solvent. Higher temperatures generally result in lower oil viscosity, allowing for easier oil flow and improved extraction efficiency. However, it is important to exercise caution and avoid exceeding the boiling point of the solvent, as this may lead to solvent evaporation and potential safety hazards.

To strike the right balance, the temperature of the soybean material should be carefully controlled within a range of 45 to 55°C. This temperature range ensures favorable oil viscosity while preventing excessive solvent evaporation. It is crucial to note that the temperature should not exceed 60°C to maintain the integrity of the material and avoid any adverse effects on the extraction process.
