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.
LD brand 6LD is the new stLDe screw oil press machine is a newest innovative one .It can extract rapeseed, peanuts, soybean, sunflower seeds and other kinds of vegetable oil materials. It adopts micro electric control, infrared heating, vacuum filter, three grade pressing, It not only can hot-pressing but also can cold-pressing which is the most optimal equipment for individual processing.
Technical parameters specification :
|Screw speed||30-45r/min||30-40 r/min||30-40 r/min||28-40 r/min||28-40 r/min|
1. High oil yielding, low oil residual in the cake:The oil left in cake is less than 6%. The cake thickness can be adjusted once the machine stops running;
2. Compact size: only 10-20m2 is enough.
3. High purity: machine surface is made of chrome plated stainless steel, in line with food hygiene standards.
4. Easy operation. You should operate as per the instruction.
5. Components:Screw pressing part, Electrical controlling system, automatic heater, adjusting mechanism, driving unit and vacuum oil filter etc.
6. Multi-functional: Used for pressing soybean, sunflower seeds, peanut, sesame, rapeseeds, flax seed, camellia, cotton seed, cashew, hemp seed, linseeds, coconut(copra), palm, palm kernel, pumpkin seeds, and walnuts and all the oil crops.
it can save 60% labor for equal output and 40% labor cost per day for one
or two people are able to make production.
it can be used to completely press more than 20 kinds of oil crops, such as
peanuts, sesame, vegetable seeds, soybean, oil sunflower and flax by third levels for one time.
3.Pure oil quality:
the bag filter is used to remove residue so as to ensure the pure oil
quality and meet the standard of health quarantine .
an area of 10-20 m2 workshop can meet the need of production.
5. Using vacuum filter, it is able to simply filter the crude oil after pressing
6. It is able to save labour, about 60% . One or two person is for per machine
7. Protection the environment, comparing with the traditional oil press machine,
it is about to meet the standard of green environment.
8. Low investment, high profit.
1.When oil press is on work, material enters the extruding chamber from the hopper and then moves forwards by the rotating pressing screw and is pressed.
2.Under high temperature condition in the chamber, there is quite strong friction among press screw, chamber and the oil materials.
3.On the other hand, root diameter of the pressing screw carries larger from one end to the other.
4.Hence when rotating, the thread not only pushes particles moving forwards but also turns them outwards as well.
5.Meanwhile, particles adjacent the screw will rotate along with screwÃ¢ÂÂs rotating, causing every particle inside the chamber to possess different speed.
6.Therefore, relative movement among particles creates neat which is necessary during manufacturing because of helping protein change property, damage colloid, increase plasticity, decrease oilÃ¢ÂÂs elasticity, resulting in high oil.
