2.Main Equipment Introduction of Rice Bran Oil Making Machine :

1) Magnetic Selection: Cylinder Magnetic Selector is mainly composed of the shell, rotary door, and magnetic core. The magnetic core consists of shunt umbrella hat, magnetic ring and magnetic core cylinder. The materials will fall down from the upper flange mouth, homodisperse fall through a shunt umbrella hat, during this process the mixing iron impurity will be quickly attracted by the magnetic ring, thus separated with the oil material. The Cylinder magnetic selector has the advantages of running without electric power, saving energ, and ease-maintenance.

2) Bran&Chaff Separation: The Bran&Chaff Separation is mainly achieve by Chaff &Bran Separation Sieve. For the rice bran is mixed with broken rice, fine broken rice, and sometimes even the integrity rice mixed in for the sieve damage or poor assembly reasons. So if they were not separated out, it will accelerate the abrasion of the extruder. What's more, the broken rice contains many starch, this will lead the problem of the failure of pressure formation. This separation sieve has four layers screens, this is equivalent to two screens yield, with the characteristics of large output, good separation effects.

3) Softening: The Vertical Softening Pot consists of several layers of super-posited pots, each layer of the pot structure of is basically the same. They all have the edge and bottom laminated sandwich, the steam enters through the sandwiches to heat and soft the material. There has a vertical axis through the center of each layer of the softening pot, and each layer of the pot has two paddle stirring wings, which are fixed on the vertical axis, the paddle stirring wing stirs the materials. And each layer of the pot has bed opening and each bed opening has an automatic flow controlling gate, through controlling the blanking quantity reach the goal of controlling the height of the material height. Meanwhile, each layer of the sidewall of the pot body has the exhaust pipe, the exhaust pipes are connected to the exhaust collector, thus to drain the evaporating steam in the process of softening.

4) Extrusion/Puffing: The tempered rice bran will be extruded by the extruder in order to strengthen the extrusion effect. The oil material will be extruded, kneaded, sheared, pressurized, and under the effected of a series of wetted the gushed steam and friction functions, the oil material's cell has been completely destoried, the oil will be fully exposed. At the end of the extrusion screw, the material pressure and temperature is very high, the high pressure and temperature material get out of the hydraulic die head will expand and the moisture of the material will evaporate quickly for the sudden release of the pressure, then we can get the loose, porous and high strength extrusion materials.

3.1 Decoloration Technology:

Adding high-efficiency activated clay to the oil, heating under 80TPD Rice Bran Oil Making Machine condition to heat adequately, so that the pigment solid tiny particles suspended in the oil can be adsorbed on the clay grains, then being filtered by the blade filter. This system has perfect arrangement, reliable performance, high configuration main equipment -- decolorizer and leaf filter, thus can guarantee the high quality of the Oil's decoloration and separation.

This Technology has the advantages of the following:

1) In the process of decoloring. the clay and oil will be mixed under 80TPD Rice Bran Oil Making Machine circumstances, this avoids

the effect of air, thus the clay has higher using rate and better decolorization. At the same

decolorization effect, the clay consumption will be lower;

2) Auto-weighing the clay addition ratio accurately according decoloring needs, accurate, automatic

metering;

3) The mixing process makes all clay particles can be contacted with oil;

4) The temporary storage tank of decoloring adopts negative pressure, this can avoid the oil and air contact effectively, so that the quality of the intermediate products and terminal products more stable;

5) The decolored oil will be filtered in aright-right stainless steel filter filter, the residual oil of the meal is low, the operation is easy and the equipment's failure rate is also low.
