Rice Bran Oil Machine/Rice Bran Oil Extraction Plant
Rice bran oil production line includes pretreatment, extraction and refining process to get edible oil. Rice bran is the by-product of rice milling, the oil contents are different due to the different varieties and difference in the number of inclusions in rice bran, which is usually 12% - 20%.
Rice bran oil extraction is mainly composed of the following parts:
The pretreatment process
Rice bran→magnetic separation, floury product separation→softening and conditioning→rice bran puffing→drying and cooling→ the extraction process.
The extraction process
solvent solvent recovery
↓ ↓
Puffed rice bran→ oil extraction→ mixed oil processing→ crude oil
↓
Recovery of solvent ←evaporation of wet meal→ product meal
Pretreatment mainly includes rice bran chaff separation process, softening process and rice bran puffing process.
Extraction mainly includes extracting system, evaporation system and cooling system.
Rice bran oil refining includes continuous dephosphorization and degumming process, physical deacidification and deodorization process, continuous dehydration process, decolorization and filtration process, crystallization and crystal growing process, dewaxing process and electrical control system.
The refining process
Rice bran crude oil→phosphoric acid degumming→ washing and drying→ dewaxing→ decoloring→ physical deacidification and deodorization→ degreasing→ refined oil

Characteristics of rice bran oil processing technology of Henan Huatai cereal and oil machinery:
1.Continuous alkali refining can shorten the contact time of oil and alkali, reduce oil saponification and oil loss and improve the efficiency.
2.Decolorization combines premix and steam mixing decolorization that enhances the decolorization effect and saves the amount of clay. The operation is simple and convenient. The state of negative pressure avoids contact of hot oil with oxygen in the air, ensures the oil quality and inhibits the rise of acid value and lowers peroxide value.
3.Physical refining adopts the new type of continuous deacidification and deodorization, suitable for plant oil with high acid value and low resin content. Actual production proves that the process has the following advantages: good acid removal ability, good thermal decoloration effect, high rate of refining and better oil quality.
4.Henan Huatai rice bran oil process has multiple heat exchange that makes full use of the system heat source, effectively reduces the steam consumption. It can also be adjusted with flexible operation, automation, environmental sanitation and so on.
Henan Huatai Cereal and Oil Machinery Co., Ltd. has obtained a number of patents in rice bran oil production line, including the production method of first grade rice bran oil refining and complete sets of first grade rice bran oil refining equipment.
