About LD'e solvent extraction section:
It is utilizing for extracting the maximum oil out from the oilseeds . The final oil residue is less than 1%. It is usually suitable for processing large capacity oil seeds.
Rotocel extractor: Spray and soak the pre-pressed cake with solvent so that oil fats can be
dissolved in solvent (form miscella). After processing, you can get wet meal and miscella (mixed oil).
The pre-pressed cake or flake, firstly enters into the seal auger to avoid the solvent gas escaping. Then material enter into the box-chained loop type extractor and counter-currenting with the solvent, the grease is extracted, and miscella concentration increases from 2% to more than 25%. Then miscella is discharged from extractor, and into miscella filter for filtration. After separating fines, miscella enter into the oil tank, then pump into evaporation system. And the leached meal finally drops in DTDC through buried scraper plate.
DTDC: It is used to separate the solvent from the wet meal. Wet meals discharged from the
bottom of extractor enter the top of DTDC and land on the predesolventizing trayers where they are heated by the indirect steam, thus, some solvent in meal is evaporated and meal temperature is risen; Predesolventized meals land on predesolventizing trayers where they use the second steam in desolventizing trayers to predesolventize solvent from meal, then, meals enter desolventizing layers in which direct steam is injected.
Evaporation process: Pump the miscella ( oil with solvent) into the 1st and 2nd long-tube evaporator, then add 10% saline water to it. The phospholipid and impurities in the miscella will react with the saline water, at last the reactant precipitate, reaching the goal of purifying.
Using the secondary steam desolventized from DTDC desolventizer and produced by steam-jet pump to heat and evaporate micella in the first long-tube evaporator. Export temperature reaches to 58-62℃ and concentration reaches to more than 65%. Then, micella enters into the second long-tube evaporator in which the temperature is heated to 105-110℃ by indirect steam and the concentration reaches to more than 95%.
Then miscella enters into stripper in which residual solvent in oil will be removed, the export temperature reaches to about 105℃ and the general volatile of the extracted crude oil is less than 0.30%.
