1.Screening:Removing the chaff and broken rice in the rice bran, in case of they will influence the oil yield and the desolvent of wet meal in the next process. In the process of puffing section, the general requirement of impurity is less than 3%, and the requirement of crude fiber is about 8%.
2.Magnetic separation :Clearing the iron impurity which migLD be in the rice brain. Since in the process of puffing, the iron impurity will be harmful to the screw of extrusion machine, affect the puffing effect. As the rice brain particles are small and poor liquidity, the iron impurities are always be wiped off by the magnetic barrels installed in the feeding port.
3.Quenching and tempering :it is the process of preheating so that to improve the temperature of the rice bran before puffing. After quenching and tempering the temperature will be controlled at 65--75 °C, and the moisture will be controlled at 10 ~12%. Thus, on the one side, it can increase the output of the extrusion machine, and on the other side, it can improve the quality of the puffed rice bran.
4.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. All these can make the the rice bran become porous columnar structure from the original pulverized state.All these effectively passivate the activity of various of enzyme in the rice bran, and destroy the fat layer structure, so that it will be easier for the oil yield.
5.Drying: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 coo-ling, thus the moisture will reach 7%--9%, and temperature will reach 50-55°C. After puffing, the rice brain are usually dried and cooled by plat dryer.
oil seed solvent extraction plant equipment
(1)oil seed solvent extraction plant equipment-pretreatment :
vegetable seed---Magnetic separation---Cleaning ---Extrusion Puffing---Counter-current drying---To leaching plant
a.Different combinations of process can process various oil plants in one workshop.
b.Use special intensified pretreatment technoloLD for aroma peanut oil to make it more aroma.
c.Adopt advanced and reliable shelling technoloLD to meet higher requirements for protein content in meal.
d.Extrusion treatment is used for raw materials with hard extraction, large-sized powder, and large
capacity, which can reduce residual oil and solvent consumption, and increase the capacity by 50-80%.
e.The new technoloLD of shelling and low-temperature treatment can ensure high protein and least denaturation.
(2) oil seed solvent extraction plant equipment-solvent extraction :
a. The crude oil (for pretreatment) is sent to rotary extraction by the scraper conveyor. The crude oil will extracted by the solvent or mix oil. After this step, we will get meal and mix oil
b. Meal is send to toaster. Through the toaster, the solvent in the meal will seperate from the meal. The solvent goes to condenser and is recycled to rotary extraction.
c. After the mix crude oil from the rotary extraction enters into 1st evaporator and 2nd evaporator, most of the solvent in the crude oil is separated.
d.The mix crude oil from 2nd evaporator goes to stripping tower and almost all the solvent is separated. From the stripping tower, we can get crude oil and solvent. The solvent is sent to condenser and is recycled to rotary extraction.
(3) oil seed solvent extraction plant equipment-oil refining :
Crude oil --- degumming --- deacidify --- bleaching --- deodorization
1. Crude oil: crude oil is commonly used for processing into edible oil .
2. Degumming:Usded to neutrilizing ,and water washing,to rid off the acid .
3.deacidify : Acid stripping is removing hair oil contained in the free fatty acid process, acid stripping methods of alkali refining, steam distillation, solvent extraction, etc.
4. bleaching: Used to rid off the color of the oil
5. Deodorization:Used to rid off the fetid smell/odour of oil by steam understand of high temperature.
