The rice bran oil production line uses pretreatment, leaching, and refining to obtain edible oil. 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:

1. Pretreatment process:

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

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

2. The leaching process:

                                            Solvent            Solvent recovery

                                                 ↓                             ↓

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

                                                 ↓

Solvent recovery ← steaming off wet meal → finished meal

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

3. Refining process:

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

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.

4. The characteristics of the rice bran oil production process of Henan Zhongxing Grain and Oil Machinery Co., Ltd.:

(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 a combination of premixing and steam agitation decolorization process, 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 suppresses the acid value. The recovery of the product reduces the peroxide value.

(3) 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 and good thermal decolorization effect , The refining rate is high, and the oil quality is relatively good.

(4) Henan Zhongxing's rice bran oil production process performs multiple heat exchanges, makes full use of the system heat source, effectively reduces steam consumption, and also has the advantages of process adjustment, flexible operation, automation, and environmental sanitation.

Henan Zhongxing Grain and Oil Machinery Co., Ltd. manufactures rice bran oil extraction production line equipment, including the production method of rice bran first-grade oil refining, and the complete set of rice bran first-grade oil refining equipment.
