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.
Costomers are our Bosses!
Simple in structure and stable in performance;
Additional horizontal grid plate prevents the miscella against flowing back to material cell and thus to ensure good extraction effect;
-ray material level-control ensures consistent feeding, and keeps constant material level in the material vessel to prevent the solvent vapor overflowing outside.
The wet meal is discharged by Material Discharger. Which continuously discharge the wet meal onto the Wet Meal Conveyor. This can not only buffer impacting to conveyor, but avoid meal bridging, un-uniform wet meal discharging and extends service able lift of Wet Meal Conveyor.
Characters with crude oil refineries:
1. we using auto welding machine to make the reactor,which can quarrantee the quality of welding seam,avoid cracking and has a long life for about 8 years.
2. professional heating treatment and x-ray detection chamber for welding seam .
3. vacuum system to prevent oil gas be back to reactor causing accident.
4. with professional thermometer , professiona pressure gauge and safety valve.
1.dedusting system to prevent gas and dust from coal burning.
2.the exhaust gas will be recycled for heating reactor ,no gas pollution.
3.well sealing on every junction parts to prevent gas leak,no smelly.
Longer life :
Using Q345R special steel plate ,welding seam with auto welding an will get heating treatment and x-ray detection to extend the life of reactor to the most extend, and the life will tens years.
1. well sealing for heating system ,no gas leak and saving fuel.
2. the exhaust gas will be recycled for reactor heating
Parameters of crude oil refineries :
2~3 kg/T oil
Circulating water cooling water yield
Bleaching earth consumption
Waste bleaching earth oil content
Deodorization loss consumption
Description of crude oil refineries :
(1) The main parts are two neutralizing tank, one bleaching tank and one deodorizing.They are all hanging on the steel strucutre.
(2)It has proper staircase and railing on all the sides of steel structure at the first floor and also on staircase. There are also two filters,one is used after bleaching,one is used after deodorization.
(3) Two oil tanks : raw oil tank and bleached oil tank ,accomodated under the strucutre on the ground floor. Then cooler, thermal oil boiler, two steam generators, vacuum pump, water pumps, oil pumps and refined oil tank are arranged on the ground floor around the steel structure .
(4) 40ft. tower is erected just near the deodourizer and its complete structure is supported from the ground floor and also it is attached with the refinery structure. Berometric condenser is arranged at 40ft. heigLD to create proper vacuum.
(5) All types of pipes are interconnected as per the requirement of the refinery i.e. oil pipes , vacuum pipelines , steam pipelines, water pipelines , thermic fluid pipelines . At all appropriate places, proper valves controll the pipelines.
(6) Neutralizer is provided with thermal oil coil for heating the oil.
(7) Bleacher is provided with double pipe coil. One is for thermal oil and another is for cooling water.
(8) Deodorizer is provided with double pipe coil i.e. in both the coils, thermal oil is circulated. Steam is ejected from the stainless nozzles provided on the steam pipe cross supported at the bottom.
(9) Cooler is provided with double pipe coil. Both for cooling water.
(10) In every parts, temperature gauge is provided. Vacuum gauge is provided on deodorizer, bleacher and cooler.
(11) Neutralizer is open on the top having conical bottom.
(12) Bleacher has dished ends on both the sides. Similarly deodorizer has dished ends on both the sides. Cooler has also dished ends on both the sides.
