Leaching equipment manufacturers
One: What does leached oil mean? What is the process of leaching oil? Oil extraction equipment, new automatic screw oil press, oil press complete sets of equipment, oil filtration equipment, oil refining equipment, filling equipment and other oil equipment related problems consulting.
Two: leaching method of oil
Oil leaching method is an oil extraction method using the principle of solid-liquid extraction, selecting some organic solvent that can dissolve oil, and spraying and soaking the oil, so that the oil in the oil is extracted, and it is also a method of oil extraction rate.
Three: Compared with other oil production methods, the leaching method has obvious advantages: first, the oil yield of the leaching method is higher than that of other oil production methods, and the residue oil of the leaching method is less than 1%, and the oil meal after oil extraction contains higher protein, which can be used as raw materials for livestock and animal feed production; Third, the processing cost is low, due to the use of non-mechanical methods, especially the increase of production scale, so that the processing cost is lower; The leaching method is easier to achieve automatic control of production, and the fifth is a good production environment, because it is closed production, no leakage, no dust, and low temperature; Sixth, the quality of the crude oil produced is good, because of the selectivity of the dissolution of the leaching organic solvent, the non-lipid lipid soluble impurities can be effectively controlled in the process of oil leaching.
The basic process of oil extraction is that the oil is soaked and leached with organic solvent after some pretreatment, and the liquid part of the extracted oil is called mixed oil; The mixture is evaporated and distilled to produce the gross oil, and the solid material after leaching is called wet meal: the finished meal is produced after dissolution, drying and cooling. The mixed oil evaporates and wet-poisoned dry solution gas is condensed and cooled back, and the recovered solvent is recycled. This leaching process is completed in four steps, they are oil leaching, mixed oil evaporation, wet meal evaporation, solvent recovery processes.
Five: solvent
As a kind of industrial auxiliary agent, oil solvent exists in the whole oil leaching process. Therefore, the composition and properties of the solvent used have different degrees of influence on the technical index and product quality of the leaching production. The solubility of oil in solvent, the separation of solvent and oil, the separation of solvent and oil, the separation of solvent and water, the safety of leaching production, and the dissolution of fat-soluble substances in oil in solvent are closely related to the composition of the solvent. Therefore, the solvent should meet the requirements of the leaching production in terms of technology and process.
Six: the solvent requirements for oil leaching
Generally speaking, there are two main requirements for the solvent used in oil leaching: first, the oil yield obtained in the leaching process; The second is to obtain high quality oil and finished meal after leaching. Other requirements are: try to avoid the harmful effect of solvents on the human body to ensure the safety of production operations.
