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.
crude coconut oil refining processProduct Description
1. Pre-treatment Process of crude coconut oil refining process:
1,create a good production environment;
2,Minimize the total oil loss,increase oil yield and output,also improve the quality of oil and cake meal;
3,Comprehensively utilize impurities and offal;
4,Perfectly ,match extraction production line,designing different production processes according to different oilseed.
(1.) One-time pressing and pre-pressing;
(2.)Low consumption enerLD;
(3.)Small occupation area ;
(4.)Low residual oil rate;
(5.)Low operate expense.
2. Solvent extraction Process of crude coconut oil refining process :
The solvent contain wet meal that from the extractor are sent to the DTDC desolventizerÃ¢ÂÂs pre-desolventizing layer by scraper through air locker, the bottom is heated by indirect steam to remove part of solvent; then the pre-desolventized wet meal get into the desolventizing layer, there are automatic control on the desolventizing layer to keep certain thickness of materials, then the bottom gets into the direct steam to remove all the solvent, at same time some steam condense in the meal, the moisture content of meal will sectional rise.
The desolventized meal falls onto the drying layer quantitative through rotary valve, the drying layer keeps certain materials level, then process the drying procedure, after drying get into the cooling layer to lower down the temperature, finally discharge the finished meal through automatic flow controlling gate, then though the scraper to transport the meal to warehouse.
1. Passivate and damage the anti-nutritional components such as the urea enzyme and trypsin in the meal, and improve meal value in use.
2. Control the protein denaturation degree in the meal , and improve the NSI index effectively.
3. It can better regulate the color, flavor and taste of the meal.
4. It can better reduce residual solvent in the meal and regulate the meal moisture, so as to guarantee the minimum solvent consumption and safe use of the meal.
3. Refining Process of crude coconut oil refining process :
Degumming and deacidification: The gumming is moved by phosphoric acid and hot water. There are
two ways to move the acid in the edible oil. One is chemical way, the other one is physical way.
The chemical way is using NaOH to react with acid. This way is suitable for the capacity of 5-30T per day. The physical way is using steam and centrifugal to move the acid. This way is used for
capacity from 30-2000T per day.
Decolorization: This step is used to adjust the color of the oil. You can control the color of the edible oil according to the requirement of your market.
Deodorization: The function of this step is to move the special smell in the oil. This is an important
standard for refined edible oil.
---Quality Index of Finished Products:
