Soybean oil solvent extraction plant

Description

Soybean oil solvent extraction plant 

Modern processing plants extract soyabean oil by solvent liquid transfer. Soyabeans are cleaned, cracked, dehulled and conditioned into a thin flake before they enter the extractor. Extraction is by successive, countercurrent washes of hexane solvent.

Through effects of wet penetration, diffusion and convert diffusion, soybean oil solvent extraction plant utilizes solvent to extract oil out of soybean embryos. The solvent is capable of dissolving the fat and then separating soybean oil from the mixture of oil and solvent, and obtains crude soybean oil after solvent recycled. The solvent in soybean meal is also recycled as to obtain extracted soybean meal.
Soybean oil solvent extraction plant design with lowest solvent addition. We adopts vacuum evaporation, and solvent soaking or spraying method to extract crude soybean oil from soybean with high oil yield and low residual oil

For a good operation, soyabeans must be clean, undamaged and at the correct moisture and temperature. Parameters of the process in the plant are: tonnage, hexane loss and energy usage. Oil quality is measured in terms of free fatty acids, absence of residual hexane and crude oil color. Meal quality is determined by residual oil, moisture, protein, urease activity protein solubility and mesh size in the finished product. Innovations at modern plants include degumming of the oil, lecithin drying and blending and production of soyabean meal with high protein solubility for human consumption
