Alkali refining is a refining method that neutralizes free fatty acids with alkali and removes some other impurities at the same time. There are many kinds of alkali used, such as lime, organic alkali, soda ash and caustic soda. The most widely used d

The so-called hydration refers to a de-impurity method in which a certain amount of hot water or dilute alkali, salt and other electrolyte solutions are added to crude oil to aggregate and precipitate water-soluble impurities and separate from oil.

①Principle of precipitation Precipitation is a method of using the different specific gravity of oil and impurities to separate the two naturally with the help of gravity. ②Precipitation equipment The precipitation equipment includes oil pool, oil t

According to operating characteristics and selected raw materials, the methods of oil refining can be roughly divided into three methods: mechanical, chemical and physical chemical methods.

Technical parameters of solvent extraction workshop-Parameters used in calculation of related equipment;Consumption indicators;Piping system design.

Direct extraction process: the flake thickness is less than 0.3 mm, and the moisture content is less than 10%; Pre-press extraction process: the maximum diagonal of the flake does not exceed 15 mm, the fines content (below 30 mesh) is less than 5%, a

Process equipment：At present, the commonly used methods mainly include: solvent recovery from vent gas with paraffin oil and freezing recovery at low temperature.

Oilseed and oil processing technology-Condensation and cooling of solvent vapor：Process flow,Condensation and cooling of solvent vapor,Solvent and water separation,Recovery of solvent in waste water

Process flow:Miscella filtration → miscella tank → first evaporator → second evaporator → stripping tower → extraction crude oil.

The meal discharged from the extractor contains 25%-35% of solvent. In order to recover these solvents and obtain better quality meal, heating can be used to desolvent the solvent.

The flakes or pre-pressed cake formed by the pre-treatment of the oil seed is sent to the extractor by the conveying equipment, and the concentrated mixed meal and wet meal are obtained after being extracted by the solvent.

Whether the extraction production can proceed smoothly is closely related to the selected process, which directly affects the product quality, production cost, production capacity and operating conditions of the oil plant after it is put into producti

The classification of oil-making process by solvent extraction method can be divided into batch extraction and continuous extraction according to the operation mode.

Oil production by solvent extraction is an oil production method that uses the principle of extraction, selects a certain organic solvent that can dissolve oil, and contacts the oil (soaking or spraying) to extract the oil in the oil seed.compared wit

Power screw oil press is an oil press that is driven by power and uses a screw shaft to continuously rotate in the cage bar to extract oil from the flakes.

Cooking is one of the important processes in the oil production process. Because cooking can take advantage of the effects of moisture and temperature. the effect of cooking has a direct impact on the smooth progress of the entire oil production proce
