Product Description
Soybean Making Oil Project
1. Technical indexes of soybean pretreatment production line
soybean pretreatment workshop process:Soybean →magnetic selection →cleaning,stones removal → crushing → softening→ flaking→ drying→ to extraction workshop
2.Extraction plant including extraction section, desolventizing section, evaporation section, solvent recovery section, ect.
Extraction sention:
Soybean flake are conveyed into the hopper of extractor by feeding scraperset, the material level is equipped with automatic control, the materials running a cycle in the extractor from feed port to discharging port(go through two times reorganization, times spray, drip dry), between the inlet and discharge port using decreasing concentration mixed oil spray, before entering the drain period, then use fresh solvent spray, wet meal discharge from extractor bottom and enter into the wet meal scraper.Thick mixed oil pumped into mixed oil tank by thick mixed oil pump after suspension separator to remove meal power, then pumped into the mixed oil tank to further remove impurities.
Desolventizing section:
The wet meal discharged from the extractor, by wet meal scraper entered into the upside pre-desolventizing layer of DTDC desolventizing machine, use indirect steam heating, make part solvent evaporation, direct steam penetrating into meal from the bottom hole, distill the solvent in the meal , to remove the solvent, part steam condensation in the meal, have the effect of destroying the activity of the enzyme in the meal. Desolventizing meal dropped in the lower drying laye by the discharge valver, the air by the fan after heating into hot air blown into the bottom of the dry layer to dry meal, Wet air draw out from the dayer layer upside by draft fan, through cyclone separator separate out the meal power discharge in the air, the meal power through cyclone separator bottom fall on meal scraping board, then through level scrapper machine sent to the meal warehouse.
Evaporation section:
Mixed oil through secondary suspension separated into the first evaporator, secondary steam of DTDCdesolventizing machine as the first evaporator heat source and the evaporate solvent vapour from the gas-liquid separation chamber top of the first evaporator into the evaporative condenser, evaporative condenser Soybean Making Oil Project by low Soybean Making Oil Project jet pump to maintain.The concentrated mixed oil discharge from the first evaporator bottom of the separate chamber, after mixing oil heat exchanger in the second evaporator, the second evaporator with indirect steam heating. Steamed out of solvent vapour and first evaporator with the solvent vapour into the evaporative condenser, the second and the first evaporator in the same Soybean Making Oil Project evaporator. Further concentrated mixed oil flowed from the second evaporator bottom of the separation chamber, then pumped into the upper stripping tower, the department of the stripper bubbled into steam directly, take off the residue solvent, mixed gas enters the stripping condenser, stripping condenser Soybean Making Oil Project by high Soybean Making Oil Project jet pump to maintain. the stripper bottom is equipped with liquid level control device, to ensure the stable flow of liquid seal and refined oil, crude oil pumped out by stripping pump by Soybean Making Oil Project drying, crude oil into temporary storage tank after cooling.
Solvent cooling and water diversion section:
Stripping condenser no vapor condensate by high Soybean Making Oil Project jet pump is pumped into the first evaporator shell,, evaporative condenser not vapor condensate from low Soybean Making Oil Project jet pump is pumped into the first evaporator shell, the first evaporator shell not vapor condensate into the bottom of the economizer, heat exchanger with fresh solvent, gas is not condensed and then enter the DT condenser further condensation. Condensate of evaporative condenser, Condensate of gas stripping condenser from the pump to the dividing water tank dividing water. The first evaporator, Condensate of energy saving device shell and other condenser flowing into the dividing water tank by itself, after dividing water, solvent into the solvent turnover Library. By fresh solvent pump into the economizer heat transfer then into the circular extractor for recycling, Wastewater from the water tank into the distilled water tank to steamthe residual solvent, into the water seal tank.
Exhaust gas absorption section
Uncondense gas from exhaust condenser enters the bottom of the absorb tower, cooling water is sprayed from the top of the tower, passing the filler, and counter current contact with exhaust gas to absorb solvent, after absorbing, exhaust gas is discharged outside from the top of the tower by the fan.
3. The refining machine section
