rice bran oil production line

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%.

1. The rice bran oil extraction production line is mainly composed of the following parts:

The pretreatment of rice bran pretreatment section, rice bran oil extraction section, and rice bran oil refining section mainly include 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 is refined into continuous dephosphorization and degumming section, physical deacidification and deodorization section, continuous dehydration section, decolorization filtration section, crystallization and crystallization section, dewaxing section and electrical control system.

2. Process characteristics of rice bran oil extraction production line:

(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 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 rice bran oil production line has multiple processes for heat exchange, making full use of the system heat source, effectively reducing steam consumption, and at the same time having the advantages of adjustable process, flexible operation, automation, and environmental sanitation.
