1. Rice Bran Pretreatment Workshop

  Rice bran→Magnetic separation→Cleaning 

→Extrusion Puffing →Countercurrent drying

2. Rice Bran Solvent Extraction Workshop

Material embryos→Extraction→Wet meal→Evaporation→Cooling→Product meal packing-

Mixed oil→Filter→Negative pressure evaporation →  Crude oil -Solvent recovery

3. Crude Rice Bran Oil Refining Workshop

crude oil---1.phosphoric acid degumming ,washing,drying---2.dewaxing---3.first time decolorization---4.AB twin towers physical deacidification--- 5.alkali refining---6.second time decolorization---7.eacidification,deodorization---8.derosination ---finished product(8section).

Producing grade-1 and grade-2 oil use physical-chemistry 1-8 sections.The grade-3 and grade-4 oil only need  full-physical 1--4 section.
