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.
Batch refining machinery canola oil machinery from famous brand
Shandong Leader LD Grain & Oil Machinery Co,. Ltd has set up his own Mechanical design and research institution. It covers 27000 square meters and contains 12 standardized production workshops, more than 100 sets of large scale processing plug welding and assembly equipments.
MAIN PROCESS OF REFINING:
Purpose: Oil refining is based on 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.
It is suitable for refining various crude vegetable oil, such as sunflower seed oil, tea seed oil,
groundnut oil, cottonseed oil, palm oil, rice bran oil, soybean oil, corn oil and palm oil, etc.
Degumming is the first and basic step in the crude oil refinery plant, degumming process aiLD to removing the gum impurities in the crude oil to make it suitable for further refinery process, hydration degumming and special acid degumming are the two main methods.
The deacidify system uses versatile neutralization technoloLD, which is developed to deal with oilseeds of different species and qualities in the oil refining plant, it can realize both degumming and neutralization processes by adding alkali, water and acid, then with FFA, crude phospholipids and moisture all removed, the oil and by products (soap foot, phospholipids) are separated.
The oil bleaching is also named decolorization in oil refinery processes. This processÃ¢ÂÂs main purpose is to remove the product of oxidation, pigments, phospholipids, soap materials from the oil. In the oil refinery plant, this process can improve the oil color as well as supplies high quality oil for the deodorization process.
Deodorization section is very crucial in edible oil refinery plant in first grade oil production as it improves the flavor of the oil; the quality of deodorization equipment has great effect to the oil quality.
