Oil extrusion is one of the commonly used processes in oil extraction. Oil extrusion is the process of using extruder machine to transform raw embryos, broken oil seeds or whole oil seeds into porous puffed pellets. It is often used for pretreatment section of soybeans, rice bran and other oils before extraction.
Many of the processing of rice bran oil adopts the expansion-extraction process. In production, the cleaned rice bran is extruded and puffed at high temperature and high pressure by the extruder machine to change the rice bran from powder to loose and porous puffed pellets. The expansion-extraction process puffs the raw materials in advance to form a porous structure, which greatly enhances the permeability to the solvent.
After expansion, the oil cells are destroyed, and the oil is on the surface of the puffed oil. The extraction time is shortened, the extraction efficiency is improved, and the extraction effect is also more sufficient. The flexibility of this process enables the equipment to flexibly adjust the processing method according to the characteristics of the raw materials and market demand.
The puffing process can change the original morphology and structure of rice bran, making it more conducive to subsequent extraction and oil production. For oilseeds with low oil content, it can fully extract the oil from the oilseed, and the residual oil of the extracted meal can be controlled within 1%. The protein denaturation of the oilseed during the rice bran oil extraction process is small, which improves the quality of the meal and the value of the cake.
The expansion-extraction equipment has high efficiency and large processing capacity. It can quickly process a large amount of rice bran raw materials to avoid the rancidity of raw materials caused by long-term storage, affecting the oil yield of crude rice bran oil and the quality of oil. The rice bran extruder has a high degree of automation, good environmental hygiene, and low labor intensity, which can meet the production needs of rice bran oil factories with high efficiency and output.
