Product Description
The leaching method for oil production is based on the principle of extraction. An organic solvent that can dissolve grease is selected (normally hexane or 6# solvent). After contact with the oil (soaking or spraying), an oil-making method that extracts the grease in the oil.
Extraction Processing
Soaking the pretreated oil seeds (or pre-pressed oil cake) in the selected solvent to dissolve the oil in the solvent (composition of the miscella oil), then separate the miscella oil from the solid residue (meal), and then evaporate the miscella oil at different boiling points , Stripping, so that the solvent is vaporized into vapor and separated from the oil, thereby obtaining grease (extracted crude oil). The solvent vapor is condensed, cooled and recovered and then reused. The meal also contains a certain amount of solvent, and the dried meal is obtained after desolventizing and drying. The solvent vapor volatilized during desolventizing and drying is still condensed and cooled for recycling.
Commonly used leaching equipment includes the Rotocel extractor and the Chain type extractor.
The Rotocel extractor adopts rack drive, low speed, low power, stable operation and no noise;
The feeding system automatically adjusts the speed of the airlocker and the main engine according to the feeding materials, which is conducive to the formation of micro-negative pressure inside the extractor and reduces solvent leakage;
The design of miscella oil circulation principle is beneficial to reduce the input of fresh solvent, reduce the residual oil in the meal, increase the concentration of miscella oil, and achieve the purpose of energy saving by reducing the amount of evaporation;
The high material layer transition design of the extractor is conducive to the formation of immersion leaching and reducing the content of meal powder in the miscella oil, which is conducive to improving the quality of crude oil and reducing the scaling of the evaporation system;
The self-cleaning miscella oil filter matched with the extractor is a new patent product specially developed by our company, which effectively filters the meal powder in the miscella oil.
Adopt micro-negative pressure evaporation process to save steam consumption and cost.
The hydrEspecially suitable for the leaching of various pre-pressed cakes.
