เหตุใดจึงมีผงในน้ำมันถั่วเหลืองสกัดด้วยตัวทำละลาย? จะแก้ปัญหาอย่างไร?

The solvent extraction method for producing soybean oil has high oil extraction efficiency and lower residual oil rate. However, some soybean oil processing manufacturers have found that some powder will remain in the extracted soybean oil during the extraction process. เหตุใดจึงมีผงในน้ำมันถั่วเหลืองสกัดด้วยตัวทำละลาย? The reason is mainly due to the oil properties of soybeans, the equipment selection and whether the filtration is thorough. This article will introduce some solutions for solvent extraction soybean oil powder, such as configure softening equipment in the pretreatment stage, equip with complete soybean oil refining equipment, and maintain and operate equipment properly.

เหตุผล

:

: If the extraction equipment is not properly adjusted or maintained, it may also lead to the presence of powder in the oil. For example, if the gap of the rolling mill is too small, it will cause excessive crushing of soybeans and generate more powder.

3. การกรองที่ไม่สมบูรณ์: During the soybean oil solvent extraction process and subsequent oil treatment, if the filtration equipment or process is faulty, it is unable to completely remove the solid impurities and powder in the oil, resulting in powder remaining in the soybean oil.

โซลูชั่น

1. Configure Softening Equipment in the Pretreatment Stage

: For example, vertical softening pots are simple in structure and relatively inexpensive, with a good water regulation effect. Having a large single-unit processing capacity, low power consumption, and no dead corners for materials. Through the softening pot, adjusting the water content and temperature of soybeans can increase their plasticity, thereby reducing the amount of powder produced during the subsequent crushing and flaking processes.

: Strictly control the temperature and water content of the soybeans during the softening process, Which can make the rolled flakes have better elasticity and plasticity and solve the problem of powder in solvent extraction soybean oil.

2. Equip with Complete Soybean Oil Refining Equipment

This is also a solution for solvent extraction soybean oil powder. Carry out Degumming, Deacidification, Decolorization and Deodorization: Add phosphoric acid, lye, decolorizing agents and other substances to the oil to make them react with colloidal impurities, acidic substances, pigments and other impurities in the oil, so as to remove these impurities. Degumming can remove phospholipids and other colloidal substances, deacidification can reduce the content of free fatty acids, decolorization can remove pigments, and deodorization can remove odor-causing small molecules in the oil under high-temperature and oxygen-free conditions.

: Use leaf filters and other equipment to conduct precision filtration on the oil after degumming, deacidification, decolorization and deodorization, so as to fully filter out the generated impurities and some original soybean powder, and obtain clean solvent-extracted soybean oil.

3. Maintain and Operate Equipment Properly

การบำรุงรักษาอุปกรณ์ตามปกติ: Perform regular inspections and maintenance on extraction equipment, rolling mills, filters and other equipment to ensure their normal operation. Check and replace worn parts in a timely manner to avoid problems such as improper equipment operation causing excessive powder.

: Operators should strictly follow the operating procedures, adjust the equipment parameters correctly, such as controlling the appropriate temperature, time and solvent ratio in the extraction process, and adjusting the rolling mill gap reasonably to avoid excessive crushing of soybeans, so as to solve the problem of powder in solvent extraction soybean oil.
