Solvent extraction machine palm oil extraction machine price

Oil extraction machine price, Solvent extraction machine palm oil extraction machine price. Mixed oil vacuum evaporation process: The liquid flowing out of oil extractor is mixed oil of oil and solvent. The solvent is separated from the mixed oil according to the vaporization temperature difference between solvent and oil, we currently use vacuum evaporation process, can reduce leakage of solvent, reduce solvent consumption. After separation of the solvent vapor is condensed back cooling recovery extractor used again, improve the efficiency of solvent. After the separated solvent vapor is condensed, cooled and recovery back to extractor for second use, which can improve the use efficiency.

Advantages of vacuum evaporation:

1, high evaporation efficiency of vacuum evaporation, desolventizing thorough, low solvent consumption of crude oil.

2, use secondary steam of steam evaporator and remaining steam of steam jet pump steam as a heat source of first steam evaporator, saving energy, while reducing the configuration area of condenser, saving investment.

3, due to the stripping temperature is low, the color of crude oil is light, good quality, low residual solvent.

Process description:

1,The main advantage of full vacuum evaporation process lies in energy savings of 20% and improving the quality of soybean oil to reduce refining losses, the production process can reduce production costs by about 15%.

2,To cushion the flow of blended oil mixing tank for the temporary storage tank, mixing oil through the pump into the first evaporator for evaporation, the first evaporator is working under vacuum conditions, thus the use of secondary steam of steam evaporator as heat source of first evaporator, greatly achieve energy-saving purposes.

3,Heat exchange between the mixture oil from first evaporator and crude oil from the stripper, to achieve save energy.

4,Mixing oil through feed pump of second steam evaporator into the second evaporator, second steam evaporator and first steam evaporator work under the same negative pressure, the heat source of second is indirect steam.

5,The mixed oil after second evaporator is pumped into stripper by stripper feeding pump, working conditions of stripper is in vacuum, by direct steam stripping can make the total volatiles in crude oil fall down to 0.3% or less.

6,Mixed oil from the top of stripper goes into butterfly dish, falling layer by layer, while direct steam is injected into the bottom, removing residual solvent. Vacuum the condenser outlet top pick, The top outlet is directly connected to vacuum condenser, keep stripper work under negative pressure by the high vacuum jet pump, the crude oil extracted by stripper extraction pump from the stripper bottom, and by crude oil cooler, and take oil-oil heat exchange with mixed oil in the second evaporator, then enter the outdoor crude oil tank.

Conclusion: The new structure of stripper will make stripper and crude oil tank into one, unique spherical baffles make oil flow uniformity and dispersion, making the vapor and liquid contacting uniform, thorough, strong capability of removing solvent, and reduce the high-low phenomenon of residual solvent in crude oil caused by vapor fluctuations in production, eliminating the short circuit phenomenon in rising process of direct steam, the total volatiles in crude oil greatly is reduced, to ensure refining safe of extracted crude oil. Disc is made of stainless steel, effectively reducing the film's coke. Device structure design is extremely easy for us to clean and maintain.

Negative pressure generated by the evaporation process is: in evaporative condensers with primary exhaust steam jet pumped, sprayed into the first evaporator shell. Negative pressure of stripper is that the tail gas through stripper condenser is pumped out by grade one steam jet pump, same injected into the first evaporator shell. The non-condensable gases of first evaporator shell enter the condenser of steam evaporator.
