Rice bran oil extraction equipment

Rice bran is a by-product of rice processing. The oil content varies with different varieties and the number of inclusions in the rice bran, usually 12%-20%.

Rice bran oil is mainly composed of the following parts:

Pretreatment process:

Rice bran → magnetic separation → bran and rice separation → softening and tempering → rice bran puffing → drying and cooling → to the leaching workshop


Leaching process:

      Solvent            solvent recover

            ↓                         ↓

Puffed rice bran → oil leaching → mixed oil treatment → crude oil


Solvent recovery ← steaming off wet meal → finished meal


Refining process:

Rice bran wool oil → phosphoric acid degumming → washing and drying → dewaxing → decolorization → physical deacidification and deodorization → degreasing → refined oil


The pretreatment mainly includes rice bran separation section, rice bran softening and tempering section and rice bran expansion chemical section.

The leaching is mainly the leaching system, the evaporation system, the evaporation system and the condensation system.

Rice bran oil refining consists of continuous dephosphorization and degumming section, physical deacidification and deodorization section, continuous dehydration section, decolorization and filtration stage, crystallization and crystallization section, dewaxing section and electrical control system.

The characteristics of Henan Zhongxing Grain and Oil Machinery's rice bran oil production process:

(1) Continuous alkali refining shortens the contact time of grease and lye, reduces saponification of grease, reduces refining consumption and improves efficiency.

(2) Decolorization adopts the process of premixing and steam agitation decolorization, which improves the decolorization effect, saves the amount of clay, and is simple and convenient to operate. The negative pressure state avoids the contact of oxygen in the air with hot oil, ensures the quality of the oil, and inhibits the acid value. Pick up and reduce peroxide value.

(3) The physical refining adopts a new type of continuous deacidification and deodorization, which is suitable for the deacidification and deodorization of vegetable oils with high acid value and low colloidal content. The actual production proves that this process has the following significant advantages: strong deacidification ability, good thermal decolorization effect, High refining rate, better oil quality
