Rice bran oil machine
Rice bran is a by-product of rice processing. The oil content varies with different varieties and the number of inclusions in rice bran, usually 12%-20%.
The rice bran oil extraction machine mainly consists of the following parts:
Rice bran pretreatment section, rice bran oil leaching section, rice bran oil refining section;
Pretreatment mainly includes rice bran separation section, rice bran softening and conditioning section and rice bran puffing section.
Extraction mainly includes leaching system, evaporation system, evaporation system and condensation system.
Rice bran oil refining includes continuous dephosphorization and degumming section, continuous dehydration section, decolorization and filtration section, crystallization and growth section, dewaxing section, physical deacidification and deodorization section, degreasing and electrical control system.

Features of refining process of rice bran extraction machine:
1. Continuous alkali refining shortens the contact time between oil and lye, reduces oil saponification, reduces refining consumption and improves work efficiency.
2. Decolorization adopts the combination of premixing and steam stirring decolorization, which improves the decolorization effect, saves the amount of clay, and is easy to operate. The negative pressure state avoids the contact between oxygen in the air and hot oil, ensures the quality of the oil, and controls the recovery of the acid value. , reduce the 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 colloid content. The actual production proves that this process has the following significant advantages: strong deacidification ability, good thermal decolorization effect, The refining rate is high, and the quality of the oil is better.
4. The rice bran oil extraction machine production line has multiple heat exchanges, making full use of the system heat source and reducing steam consumption. At the same time, it also has the advantages of process adjustment, flexible operation, automation, and environmental sanitation.
