Analysis of negative pressure forced leaching device for extractor
Extractor is an important equipment for oil leaching,improving the performance of the extractor not only reduces the residual oil in the meal,but also reduces the load of subsequent high-temperature desolventizing or low-temperature desolventizing,which saves steam consumption.Extractor negative pressure forced leaching device provides negative pressure to the leaching closed oil hopper using a different way to forcibly leach the low concentration miscella in wet meal materials,and achieve further reduction of solvent content in wet meal.In order to reduce the solvent content in wet meal and improve the economic efficiency of enterprise,the process,characteristics and scope of application of the negative pressure device of the extractor leaching section with liquid ring vacuum pump,steam vacuum pump and negative pressure fan were introduced respectively,and the forced negative pressure leaching closed oil hopper of different types of commonly used extractors were also described.Finally,a comprehensive analysis of the leaching effect and economic benefits were carried out.Through the negative pressure forced leaching device of extractor can effectively reduce the solvent content in wet meal,and save steam consumption in the high-temperature desolventizing and thus bring certain economic benefits for the enterprise.
