Rice bran oil press machine
To get the oil in the rice bran, we need three main parts, the first is puffing section and the second is solvent extraction section, the third is oil refining section.
The flow chart to get high quality rice bran oil:
Raw material(rice bran)→magnetic separation→floury product separation→quenching and tempering→puffing(extrusion machine)→drying and cooling→solvent extraction plant→refining plant→high quality product oil
Ⅰ.the instruction of puffing section:
1.magnetic separation: Used to clear the iron impurity which migLD be in the rice brain.
2.Screen: used to remove the chaff and second head in the rice bran, in case of they will influence the oil yield and the desolvent of wet meal in the next process.
3.quenching and tempering
Quenching and tempering is the process of preheating so that to improve the temperature of the rice brain before puffing.
4.puffing
Puffing the rice bran is injecting high pressure steam and high temperature water through the extrusion machine, so that it can improve the temperature and moisture in the extrusion machine, and can also form the high pressure to process the rice bran.
5.Drying and cooling
The moisture of puffed material comes from the extrusion machine is too big and the temperature is too high for direct leaching, the must be experience to process of drying and cooling.
Ⅱ.the introduction of rice bran solvent extraction plant
After pretreatment puffing plant, the rice bran will become meal. Since the rice bran belongs to the low oil content, so use the method of solvent extraction can ensure the max oil yield.
The brief fundamental of the solvent extraction plant:
First, send the rice bran meal to the roary extractor, the meal will be fully soaked in the extractor by the solvent. Thus, the oil in the rice bran will be absorbed in to the solvent.
Second, Separate the solvent from the soaked meal and from the miscella(solvent and rice bran oil) .Thus, the separated solvent can be used for recycling, the dried meal can be made for animal feed, and the oil will be sent to refining plant for high quality oil.
Ⅲ. The introduction of the oil refining plant
Oil refining is according to the different usage and requirements, utilizing the physical methods and chemical processes to get rid of the harmful impurities and needless substance in the crude oil, getting standard oil.
The refining of rice brain of including: de-gumming section, decoloring section, deodorizing section and dewaxing(winterization) section.
After the above processing, you can get high quality rice bran oil.
