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.

Main process about Palm kernel Solvent extraction production line machine,oil extraction equipment workshop,CKO production line extraction machine

Towline Extractor:

1) The material is divided into several independent units on the material bed, which can effectively prevent miscella at all levels from fleeing hither and thither on the material layer and ensure the concentration gradient between several sprays.

2) Immersion area appears in each lattice, which can help achieve better immersion effect.

3) The chain box is supported by track and can prolong the service life of screen deck by not touching it.

4) The towline extractor is driven by world leading double-shaft hydraulic motor, with balance force, reliable operation and less maintenance cost.

5) Specialty suitable for the extraction of high oil and high power materials, and better immersion effect can be expected for ordinary oil plants.

Wet Meal Desolventizing Process

1. Desolventizer toaster advantages:

a) Passivate and damage the anti-nutritional components such as the urea enzyme and trypsin in the meal, and improve meal value in use.

b) Control the protein denaturation degree in the meal , and improve the NSI index effectively.

c) It can better regulate the color, flavor and taste of the meal.

d) 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.

2. Negative pressure evaporation process

The liquid from the extractor is the miscella containing grease and oil, which can be separated out according their different vaporization temperatures. Our company mainly uses vacuum evaporation technoloLD, and it can reduce solvent leakage and consumption. The separated solvent vapour is cooled and recycled back to the extractor for reuse, which can improve the solvent efficiency.

3. Vacuum Evaporation Advantages:

a) Vacuum evaporation features high efficiency, thorough de-solvation and low solvent consumption in crude oil.

b) Use the second steam of desolventizer toaster and remaining steam from steam jet pump as the heat source of the first steam, which can save enerLD, reduce the condenser configuration area and save investment.

c) Due to the low temperature of the steam, the crude oil features ligLD color, good quality and low residual solvent.

4. Solvent condensation & recovery process

Solvent condensation system combines with evaporation system closely, and evaporative condenser and steam stripping condenser all work under negative pressure. Non-condensable gas enters the enerLD saver from the shell of the

first evaporator. In enerLD saver, noncondensable gas exchanges heat with condensate from the evaporative condenser. Finally, the condensate temperature discharged from enerLD saver is increased, and the solvent separated from water goes to solvent holding tank. The high temperature makes it unnecessary to be reheated for the recycling, so as to save enerLD. Noncondensable gas from enerLD saver enters desolventizing condenser, in which a great deal of gas is condensed, and the tail gas is discharged into the final condenser. The solvent gas from the extractor enters extraction condenser, and the noncondensable tail gas enters the final condenser. For the free gas in final condenser, diversion box, holding tank, underground solvent library and miscella tank, cool them with low temperatured cold water

to recycle most of solvent gas. The tail gas with little solvent goes to paraffin recovery process.
